By using What-If Analysis tools in Excel, you can use several different sets of values in one or more formulas to explore all the various results.

For example, you can do What-If Analysis to build two budgets that each assumes a certain level of revenue. Or, you can specify a result that you want a formula to produce, and then determine what sets of values will produce that result. Excel provides several different tools to help you perform the type of analysis that fits your needs.

Note that this is just an overview of those tools. There are links to help topics for each one specifically.

What-If Analysis is the process of changing the values in cells to see how those changes will affect the outcome of formulas on the worksheet.

Three kinds of What-If Analysis tools come with Excel: Scenarios, Goal Seek, and Data Tables. Scenarios and Data tables take sets of input values and determine possible results. A Data Table works with only one or two variables, but it can accept many different values for those variables. A Scenario can have multiple variables, but it can only accommodate up to 32 values. Goal Seek works differently from Scenarios and Data Tables in that it takes a result and determines possible input values that produce that result.

In addition to these three tools, you can install add-ins that help you perform What-If Analysis, such as the Solver add-in. The Solver add-in is similar to Goal Seek, but it can accommodate more variables. You can also create forecasts by using the fill handle and various commands that are built into Excel.

For more advanced models, you can use the Analysis ToolPak add-in.

A Scenario is a set of values that Excel saves and can substitute automatically in cells on a worksheet. You can create and save different groups of values on a worksheet and then switch to any of these new scenarios to view different results.

For example, suppose you have two budget scenarios: a worst case and a best case. You can use the Scenario Manager to create both scenarios on the same worksheet, and then switch between them. For each scenario, you specify the cells that change and the values to use for that scenario. When you switch between scenarios, the result cell changes to reflect the different changing cell values.

worst case scenario

1. Changing cells

2. Result cell

best case scenario

1. Changing cells

2. Result cell

If several people have specific information in separate workbooks that you want to use in scenarios, you can collect those workbooks and merge their scenarios.

After you have created or gathered all the scenarios that you need, you can create a Scenario Summary Report that incorporates information from those scenarios. A scenario report displays all the scenario information in one table on a new worksheet.

excel scenario summary report

Note: Scenario reports are not automatically recalculated. If you change the values of a scenario, those changes will not show up in an existing summary report. Instead, you must create a new summary report.

If you know the result that you want from a formula, but you’re not sure what input value the formula requires to get that result, you can use the Goal Seek feature. For example, suppose that you need to borrow some money. You know how much money you want, how long a period you want in which to pay off the loan, and how much you can afford to pay each month. You can use Goal Seek to determine what interest rate you must secure in order to meet your loan goal.

Goal Seek

Cells B1, B2, and B3 are the values for the loan amount, term length, and interest rate.

Cell B4 displays the result of the formula =PMT(B3/12,B2,B1).

Note: Goal Seek works with only one variable input value. If you want to determine more than one input value, for example, the loan amount and the monthly payment amount for a loan, you should instead use the Solver add-in. For more information about the Solver add-in, see the section Prepare forecasts and advanced business models, and follow the links in the See Also section.

If you have a formula that uses one or two variables, or multiple formulas that all use one common variable, you can use a Data Table to see all the outcomes in one place. Using Data Tables makes it easy to examine a range of possibilities at a glance. Because you focus on only one or two variables, results are easy to read and share in tabular form. If automatic recalculation is enabled for the workbook, the data in Data Tables immediately recalculates; as a result, you always have fresh data.

Mortgage Loan Analysis

Cell B3 contains the input value. 
Cells C3, C4, and C5 are values Excel substitutes based on the value entered in B3.

A Data Table cannot accommodate more than two variables. If you want to analyze more than two variables, you can use Scenarios. Although it is limited to only one or two variables, a Data Table can use as many different variable values as you want. A Scenario can have a maximum of 32 different values, but you can create as many scenarios as you want.

If you want to prepare forecasts, you can use Excel to automatically generate future values that are based on existing data, or to automatically generate extrapolated values that are based on linear trend or growth trend calculations.

You can fill in a series of values that fit a simple linear trend or an exponential growth trend by using the fill handle or the Series command. To extend complex and nonlinear data, you can use worksheet functions or the regression analysis tool in the Analysis ToolPak Add-in.

Although Goal Seek can accommodate only one variable, you can project backward for more variables by using the Solver add-in. By using Solver, you can find an optimal value for a formula in one cell—called the target cell—on a worksheet.

Solver works with a group of cells that are related to the formula in the target cell. Solver adjusts the values in the changing cells that you specify—called the adjustable cells—to produce the result that you specify from the target cell formula. You can apply constraints to restrict the values that Solver can use in the model, and the constraints can refer to other cells that affect the target cell formula.

IF function

The IF function is one of the most popular functions in Excel, and it allows you to make logical comparisons between a value and what you expect.

So an IF statement can have two results. The first result is if your comparison is True, the second if your comparison is False.

For example, =IF(C2=”Yes”,1,2) says IF(C2 = Yes, then return a 1, otherwise return a 2).

Use the IF function, one of the logical functions, to return one value if a condition is true and another value if it’s false.

IF(logical_test, value_if_true, [value_if_false])

The condition you want to test.

The value that you want returned if the result of logical_test is TRUE.

The value that you want returned if the result of logical_test is FALSE.

Simple IF examples

In the above example, cell D2 says: IF(C2 = Yes, then return a 1, otherwise return a 2)

In this example, the formula in cell D2 says: IF(C2 = 1, then return Yes, otherwise return No)As you see, the IF function can be used to evaluate both text and values. It can also be used to evaluate errors. You are not limited to only checking if one thing is equal to another and returning a single result, you can also use mathematical operators and perform additional calculations depending on your criteria. You can also nest multiple IF functions together in order to perform multiple comparisons.

B2,”Over Budget”,”Within Budget”)» loading=»lazy»>

=IF(C2>B2,”Over Budget”,”Within Budget”)

In the above example, the IF function in D2 is saying IF(C2 Is Greater Than B2, then return “Over Budget”, otherwise return “Within Budget”)

B2,C2-B2,»»)» loading=»lazy»>

In the above illustration, instead of returning a text result, we are going to return a mathematical calculation. So the formula in E2 is saying IF(Actual is Greater than Budgeted, then Subtract the Budgeted amount from the Actual amount, otherwise return nothing).

In this example, the formula in F7 is saying IF(E7 = “Yes”, then calculate the Total Amount in F5 * 8.25%, otherwise no Sales Tax is due so return 0)

Note: If you are going to use text in formulas, you need to wrap the text in quotes (e.g. “Text”). The only exception to that is using TRUE or FALSE, which Excel automatically understands.

Common problems

What went wrong

There was no argument for either value_if_true or value_if_False arguments. To see the right value returned, add argument text to the two arguments, or add TRUE or FALSE to the argument.

This usually means that the formula is misspelled.

Using IF with AND, OR and NOT functions

The IF function allows you to make a logical comparison between a value and what you expect by testing for a condition and returning a result if that condition is True or False.

=IF(Something is True, then do something, otherwise do something else)

But what if you need to test multiple conditions, where let’s say all conditions need to be True or False ( AND), or only one condition needs to be True or False ( OR), or if you want to check if a condition does NOT meet your criteria? All 3 functions can be used on their own, but it’s much more common to see them paired with IF functions.

Use the IF function along with AND, OR and NOT to perform multiple evaluations if conditions are True or False.

IF(AND()) — IF(AND(logical1, [logical2], . ), value_if_true, [value_if_false]))

IF(OR()) — IF(OR(logical1, [logical2], . ), value_if_true, [value_if_false]))

IF(NOT()) — IF(NOT(logical1), value_if_true, [value_if_false]))

The condition you want to test.

The value that you want returned if the result of logical_test is TRUE.

The value that you want returned if the result of logical_test is FALSE.

Here are overviews of how to structure AND, OR and NOT functions individually. When you combine each one of them with an IF statement, they read like this:

AND – =IF(AND(Something is True, Something else is True), Value if True, Value if False)

OR – =IF(OR(Something is True, Something else is True), Value if True, Value if False)

NOT – =IF(NOT(Something is True), Value if True, Value if False)

Examples

Following are examples of some common nested IF(AND()), IF(OR()) and IF(NOT()) statements. The AND and OR functions can support up to 255 individual conditions, but it’s not good practice to use more than a few because complex, nested formulas can get very difficult to build, test and maintain. The NOT function only takes one condition.

Here are the formulas spelled out according to their logic:

=IF(AND(A2>0,B2 0,B4 50),TRUE,FALSE)

IF A6 (25) is NOT greater than 50, then return TRUE, otherwise return FALSE. In this case 25 is not greater than 50, so the formula returns TRUE.

IF A7 (“Blue”) is NOT equal to “Red”, then return TRUE, otherwise return FALSE.

Note that all of the examples have a closing parenthesis after their respective conditions are entered. The remaining True/False arguments are then left as part of the outer IF statement. You can also substitute Text or Numeric values for the TRUE/FALSE values to be returned in the examples.

Here are some examples of using AND, OR and NOT to evaluate dates.

Here are the formulas spelled out according to their logic:

IF A2 is greater than B2, return TRUE, otherwise return FALSE. 03/12/14 is greater than 01/01/14, so the formula returns TRUE.

=IF(AND(A3>B2,A3 B2,A4 B2),TRUE,FALSE)

IF A5 is not greater than B2, then return TRUE, otherwise return FALSE. In this case, A5 is greater than B2, so the formula returns FALSE.

Using AND, OR and NOT with Conditional Formatting

You can also use AND, OR and NOT to set Conditional Formatting criteria with the formula option. When you do this you can omit the IF function and use AND, OR and NOT on their own.

From the Home tab, click Conditional Formatting > New Rule. Next, select the “ Use a formula to determine which cells to format” option, enter your formula and apply the format of your choice.

Edit Rule dialog showing the Formula method» loading=»lazy»>

Using the earlier Dates example, here is what the formulas would be.

If A2 is greater than B2, format the cell, otherwise do nothing.

=AND(A3>B2,A3 B2,A4 B2)

If A5 is NOT greater than B2, format the cell, otherwise do nothing. In this case A5 is greater than B2, so the result will return FALSE. If you were to change the formula to =NOT(B2>A5) it would return TRUE and the cell would be formatted.

Note: A common error is to enter your formula into Conditional Formatting without the equals sign (=). If you do this you’ll see that the Conditional Formatting dialog will add the equals sign and quotes to the formula — =»OR(A4>B2,A4

  3. Data Table in Excel

You can download this What-If Analysis Excel Template here – What-If Analysis Excel Template

#1 Scenario Manager in What-If Analysis

As a business head, it is important to know the different scenarios of your future project. Based on the scenarios, the business head will make decisions. For example, you are going to undertake one of the important projects. You have done your homework and listed all the possible expenditures from your end, and below is the list of all your expenses.

What-if analysis Example 1

The expected cash flow from this project is $75 million, which is in cell C2. Total expenses comprise all your fixed and variable expenses, the total cost is $57.45 million in cell C12. Total profit is $17.55 million in cell C14, and profit % is 23.40% of your cash inflow.

It is the basic scenario of your project. Now, you need to know the profit scenario if some of your expenses increase or decrease.

Scenario 1

  • In a general case scenario, you have estimated the “Project License” cost to be $10 million, but you are sure anticipating it to be $15 million
  • Raw material costs to be increased by $2.5 million
  • Other expensesOther expenses comprise all the non-operating costs incurred for the supporting business operations. Such payments like rent, insurance and taxes have no direct connection with the mainstream business activities.read more to be decreased by 50 thousand.

Scenario 2

  • The “Project Cost” to be at $20 million
  • The “Labor Daily Wages” to be at $5 million
  • The “Operating Cost” is to be at $3.5 million

Now, you have listed out all the scenarios in the form. Based on these scenarios, you need to create a table about how it will impact your profit and profit %.

To create What-If Analysis scenarios, follow the below steps.

  1. Go to DATA > What-If Analysis > Scenario Manager.

    What-if analysis Example 1-1

  2. Once you click “Scenario Manager,” it will show you below the dialog box.

    What-if analysis Example 1-2

  3. Click on “Add.” Then, give “Scenario name.”

    What-if analysis Example 1-3

  4. In changing cells, select the first scenario changes you have listed out. The changes are Project License (cell C10) at $15 million, Raw Material Cost (cell C7) at $11 million, and Other Expenses (cell C11) at $4.5 million. Mention these three cells here.

    What-if analysis Example 1-4

  5. Click on “OK.” It will ask you to mention the new values as listed in scenario 1.

    What-if analysis Example 1-5

  6. Do not click on “OK” but click on “OK Add.” It will save this scenario for you.
  7. Now, it will ask you to create one more scenario. As we listed in scenario 2, make the changes. This time we need to change Project Cost (C10), Labour Cost (C8), and Operating Cost (C9).

    What-if analysis Example 1-6

  8. Now, add new values here.

    What-if analysis Example 1-7

  9. Now click on “OK.” It will show all the scenarios we have created.

    What-if analysis Example 1-8

  10. Click on “Scenario summary.” It will ask you which result cells you want to change. Here, we need to change the Total Expense Cell (C12), Total Profit Cell (C14), and Profit % cell (C16).

    What-if analysis Example 1-9

  11. Click on “OK.” It will create a summary report for you in the new worksheet.

    What-if analysis Example 1-10

Total Excel has created three scenarios even though we have supplied only two scenario changes because Excel will show existing reports as one scenario.

From this table, we can easily see the impact of changes in pour profit %.

#2 Goal Seek in What-If Analysis

Now, we know the Scenario Manager’s advantage. What-if-Analysis Goal Seek can tell you what you must do to achieve the target.

Andrew is a class 10th student. His target is to achieve an average score of 85 in the final exam. He has already completed 5 exams and left with only 1 exam. Therefore, in the completed 5 exams.

What-if analysis Example 2

To calculate the current average, apply the average formula in the B7 cell.

What-if analysis Example 2-1

The current average is 82.2.

What-if analysis Example 2-2

Andrew’s GOAL is 85. His current average is 82.2. He is short by 3.8 with one exam.

Now, the question is how much he has to score in the final exam to eventually get an overall average of 85. It can be found by the What-If Analysis GOAL SEEK tool.

  • Step 1: Go to DATA > What-If Analysis > Goal Seek.

What-if analysis Example 2-3

  • Step 2: It will show you below the dialog box.

What-if analysis Example 2-4

  • Step 3: Here, we need to set the cell first. “Set cell” is nothing but which cell we need for the final result, i.e., our overall average cell (B7). Next is “To value.” Again, Andrew’s overall average GOAL is nothing but for what value we need to set the cell (85).

The next and final step is changing which cell you want to see the impact on. So, we need to change cell B6, the cell for the final subject’s score.

What-if analysis Example 2-5

  • Step 4: Click on “OK.” Excel will take a few seconds to complete the process, but it eventually shows the result like the one below.

Example 2-6

Now, we have our results here. To get an overall average of 85, Andrew has to score 99 in the final exam.

#3 Data Table in What-If Analysis

We have already seen two wonderful techniques under What-If Analysis in Excel. First, the Data Table can create different scenario tables based on the variable change. We have two kinds of Data Tables here: one variable Data Table and a “Two-variable data tableA two-variable data table helps analyze how two different variables impact the overall data table. In simple terms, it helps determine what effect does changing the two variables have on the result.read more.” This article will show you One variable data table in ExcelOne variable data table in excel means changing one variable with multiple options and getting the results for multiple scenarios. The data inputs in one variable data table are either in a single column or across a row.read more.

Assume you are selling 1,000 products at ₹15, your total anticipated expense is ₹12,500, and your profit is ₹2,500.

Example 3

You are not happy with the profit you are getting. Your anticipated profit is ₹7,500. You have decided to increase your per-unit price to increase your profit, but you do not know how much you need to increase.

Data tables can help you. Create a table below.

What-if analysis Example 3-1

Now, in the cell, F1 links to the “Total Profit” cell, B6.

What-if analysis Example 3-2

  • Step 1: Select the newly created table.

Example 3-3

  • Step 2: Go to DATA > What-if Analysis > Data Table.

Example 3-4

  • Step 3: Now, you will see below dialog box.

Example 3-5

  • Step 4: Since we are showing the result vertically, leave the ”Row input cell.” In the “Column input cell,” select cell B2, which is the original selling price.

Example 3-6

  • Step 5: Click on “OK” to get the results. It will list out profit numbers in the new table.

Example 3-7

So, we have our Data Table ready. To profit from ₹7,500, you need to sell at ₹20 per unit.

Things to Remember

  • The What-If Analysis data table can be performed with two variable changes. Refer to our article on What-If Analysis two-variable Data Table.
  • What-If Analysis Goal Seek takes a few seconds to perform calculations.
  • What-If Analysis Scenario Manager can give a summary with input numbers and current values together.

Что возвращает функция

Заданное вами значение при выполнении двух условий ИСТИНА или ЛОЖЬ.

Синтаксис

=IF(logical_test, [value_if_true], [value_if_false]) — английская версия

=ЕСЛИ(лог_выражение; [значение_если_истина]; [значение_если_ложь]) — русская версия

Аргументы функции

  • logical_test (лог_выражение) — это условие, которое вы хотите протестировать. Этот аргумент функции должен быть логичным и определяемым как ЛОЖЬ или ИСТИНА. Аргументом может быть как статичное значение, так и результат функции, вычисления;
  • [value_if_true] ([значение_если_истина]) — (не обязательно) — это то значение, которое возвращает функция. Оно будет отображено в случае, если значение которое вы тестируете соответствует условию ИСТИНА;
  • [value_if_false] ([значение_если_ложь]) — (не обязательно) — это то значение, которое возвращает функция. Оно будет отображено в случае, если условие, которое вы тестируете соответствует условию ЛОЖЬ.

Дополнительная информация

  • В функции ЕСЛИ может быть протестировано 64 условий за один раз;
  • Если какой-либо из аргументов функции является массивом — оценивается каждый элемент массива;
  • Если вы не укажете условие аргумента FALSE (ЛОЖЬ) value_if_false (значение_если_ложь) в функции, т.е. после аргумента value_if_true (значение_если_истина) есть только запятая (точка с запятой), функция вернет значение “0”, если результат вычисления функции будет равен FALSE (ЛОЖЬ).
    На примере ниже, формула =IF(A1> 20,”Разрешить”) или =ЕСЛИ(A1>20;»Разрешить») , где value_if_false (значение_если_ложь) не указано, однако аргумент value_if_true (значение_если_истина) по-прежнему следует через запятую. Функция вернет “0” всякий раз, когда проверяемое условие не будет соответствовать условиям TRUE (ИСТИНА).

  • Если вы не укажете условие аргумента TRUE(ИСТИНА) (value_if_true (значение_если_истина)) в функции, т.е. условие указано только для аргумента value_if_false (значение_если_ложь), то формула вернет значение “0”, если результат вычисления функции будет равен TRUE (ИСТИНА);
    На примере ниже формула равна =IF (A1>20;«Отказать») или =ЕСЛИ(A1>20;»Отказать»), где аргумент value_if_true (значение_если_истина) не указан, формула будет возвращать “0” всякий раз, когда условие соответствует TRUE (ИСТИНА).

Функция Если в Excel примеры с несколькими условиями

Пример 1. Проверяем простое числовое условие с помощью функции IF (ЕСЛИ)

При использовании функции ЕСЛИ в Excel, вы можете использовать различные операторы для проверки состояния. Вот список операторов, которые вы можете использовать:

IF-EXCEL-03

Ниже приведен простой пример использования функции при расчете оценок студентов. Если сумма баллов больше или равна «35», то формула возвращает “Сдал”, иначе возвращается “Не сдал”.

Excel-IF-04

Пример 2. Использование вложенной функции IF (ЕСЛИ) для проверки условия выражения

Функция может принимать до 64 условий одновременно. Несмотря на то, что создавать длинные вложенные функции нецелесообразно, то в редких случаях вы можете создать формулу, которая множество условий последовательно.

В приведенном ниже примере мы проверяем два условия.

  • Первое условие проверяет, сумму баллов не меньше ли она чем 35 баллов. Если это ИСТИНА, то функция вернет “Не сдал”;
  • В случае, если первое условие — ЛОЖЬ, и сумма баллов больше 35, то функция проверяет второе условие. В случае если сумма баллов больше или равна 75. Если это правда, то функция возвращает значение “Отлично”, в других случаях функция возвращает “Сдал”.

Excel-If-06

Пример 3. Вычисляем сумму комиссии с продаж с помощью функции IF (ЕСЛИ) в Excel

Функция позволяет выполнять вычисления с числами. Хороший пример использования — расчет комиссии продаж для торгового представителя.

В приведенном ниже примере, торговый представитель по продажам:

  • не получает комиссионных, если объем продаж меньше 50 тыс;
  • получает комиссию в размере 2%, если продажи между 50-100 тыс
  • получает 4% комиссионных, если объем продаж превышает 100 тыс.

Рассчитать размер комиссионных для торгового агента можно по следующей формуле:

=IF(B2<50,0,IF(B2<100,B2*2%,B2*4%)) — английская версия

=ЕСЛИ(B2<50;0;ЕСЛИ(B2<100;B2*2%;B2*4%)) — русская версия

Excel-IF-07

В формуле, использованной в примере выше, вычисление суммы комиссионных выполняется в самой функции ЕСЛИ. Если объем продаж находится между 50-100K, то формула возвращает B2 * 2%, что составляет 2% комиссии в зависимости от объема продажи.

Пример 4. Используем логические операторы (AND/OR) (И/ИЛИ) в функции IF (ЕСЛИ) в Excel

Вы можете использовать логические операторы (AND/OR) (И/ИЛИ) внутри функции для одновременного тестирования нескольких условий.

Например, предположим, что вы должны выбрать студентов для стипендий, основываясь на оценках и посещаемости. В приведенном ниже примере учащийся имеет право на участие только в том случае, если он набрал более 80 баллов и имеет посещаемость более 80%.

Excel-If-09

Вы можете использовать функцию AND (И) вместе с функцией IF (ЕСЛИ), чтобы сначала проверить, выполняются ли оба эти условия или нет. Если условия соблюдены, функция возвращает “Имеет право”, в противном случае она возвращает “Не имеет право”.

Формула для этого расчета:

=IF(AND(B2>80,C2>80%),”Да”,”Нет”) — английская версия

=ЕСЛИ(И(B2>80;C2>80%);»Да»;»Нет») — русская версия

Excel-IF-10

Пример 5. Преобразуем ошибки в значения “0” с помощью функции IF (ЕСЛИ)

С помощью этой функции вы также можете убирать ячейки содержащие ошибки. Вы можете преобразовать значения ошибок в пробелы или нули или любое другое значение.

Формула для преобразования ошибок в ячейках следующая:

=IF(ISERROR(A1),0,A1) — английская версия

=ЕСЛИ(ЕОШИБКА(A1);0;A1) — русская версия

Формула возвращает “0”, в случае если в ячейке есть ошибка, иначе она возвращает значение ячейки.

ПРИМЕЧАНИЕ. Если вы используете Excel 2007 или версии после него, вы также можете использовать функцию IFERROR для этого.

Точно так же вы можете обрабатывать пустые ячейки. В случае пустых ячеек используйте функцию ISBLANK, на примере ниже:

=IF(ISBLANK(A1),0,A1) — английская версия

=ЕСЛИ(ЕПУСТО(A1);0;A1) — русская версия

EXCEL-IF-11


If you’ve ever experimented with different variables to see how your changes would affect the outcome of a situation, you’ve done a what if analysis. 

Would you be able to sell more items if you had a sale this week? Or would you make more money by increasing the price instead? In the above scenarios, you want to know the degree to which each change affects the overall outcome. For this reason, a what if analysis is also known as a sensitivity analysis.

Most what if analyses are really mathematical calculations, and that is Excel’s specialty. To help you do a what if analysis, Excel uses commands from the Forecast command group on the Data tab to prepare simple forecasts or advanced business models.

Goal Seek

The simplest sensitivity analysis tool in Excel is Goal Seek. Assuming that you know the single outcome you would like to achieve, the Goal Seek feature in Excel allows you to arrive at that goal by mathematically adjusting a single variable within the equation.

What if analysis Excel - Goal SeekTo illustrate how it works, imagine that the bank is offering an interest rate of 9% per annum on personal loans with 24 months to repay, and that you would like to borrow $40,000. 

Using the above information, the bank calculates that the amount borrowed plus interest over the loan period will be $47,200, as shown in cell B5. The amount to be paid each month is also calculated and shown in cell B6.

What if analysis Excel - Goal SeekBy using the Goal Seek command, we can indicate a desired outcome and Excel will determine the adjustment we need to make to a single variable.

In the example above, cell B5 is dependent on the variables in cells B1, B2, and B3. Cell B6 is dependent on cells B3 and B5. Therefore, if we determine that the monthly repayment amount quoted is higher than desired, we can use Goal Seek to set the monthly amount to $1750. Excel can work backwards to change either cell B1, B2, or B3 to reach that goal.

Practically speaking, we may not have much control over the interest rate, so it is more likely that we have the option of adjusting the amount we borrow, or the repayment period. 

Our first inclination may be to find out how much we will be able to borrow if we pay $1750 per month and all other variables remain the same. Excel will change the principal (B1) based on the number we enter as the new value for cell B6.

What if analysis Excel - Goal SeekAssuming that the interest amount (9%) and loan period (24 months) remain the same, the new principal amount is calculated and displayed in cell B1 if a valid solution exists.

What if analysis Excel - Goal SeekPoints to note:

  1. The cell chosen in the “Set cell” field must be a cell containing a formula.
  2. The cell chosen in the “By changing cell” field must be a cell containing a constant.
  3. Once “OK” is selected from the Goal Seek Status window, the values on the worksheet are adjusted and are only retrievable by selecting the ‘Undo’ command (Ctrl+Z Windows shortcut/Cmd+Z Mac shortcut).

Scenario Manager

Another what if analysis tool is the Scenario Manager. This option is somewhat more advanced than Goal Seek in that it allows the adjustment of multiple variables at the same time. 

What if analysis Excel - scenario managerSome other noticeable differences between Goal Seek and Scenario Manager are listed below:

  • The Scenario Manager allows the creation of an unlimited number of possible scenarios by changing up to 32 variables at a time.
  • Each scenario can be saved for comparative purposes.
  • Scenarios may be named and edited, and a brief description provided.
  • Only constant values should be changed within the Scenario Manager — cells with formulas should not be manually adjusted.

If we continue our bank loan example, we can determine our model’s sensitivity to change by adjusting any or all of the values in cell B1, B2, or B3.

Best practice

As a best practice, the original worksheet data should be saved as a scenario so that you can revert to it after all the experiments have been completed.

Step 1 — Click ‘What If Analysis’ from the Data tab and select Scenario Manager.

Step 2 — Click ‘Add’ from the Scenario Manager pop-up window.

Step 3 — Name this scenario “Original” and enter the cell references of all cells with constant values that you may consider changing in other scenarios (maximum 32 cells). Click OK.

What if analysis Excel - scenario managerStep 4 — For the “Original” scenario, do not adjust any values in the ‘Scenario Values’ window.

What if analysis Excel - scenario managerStep 5 — Click ‘Add’ to create your first experimental scenario.

Creating experimental scenarios

When creating an experimental scenario, give the scenario a descriptive name from the ‘Add Scenario’ pop-up window. The changing cells will be the same as the ones referenced in your ‘Original’ scenario. 

Even if you will not be adjusting all the values in those cells, it is highly recommended that they remain referenced in the ‘changing cells’ field. You may place additional details about the experimental scenario in the ‘Comment’ field (see below).

What if analysis Excel - scenario managerAs illustrated above, our experimental scenario is given the name “36 months” and refers to cells B1 to B3 as changing cells. An additional comment indicates that this scenario is to determine the effect of borrowing $40,000 over a 36-month period.

In the ‘Scenario Values’ window, each changing cell is displayed as a field where we can manipulate the constant value so as to affect the outcome of the dependent cells — in our case, cells B5 and B6. As described in our scenario name and comments, we only adjust cell B3 by changing the value to 36.

To add another scenario at this point, select ‘Add’. If not, click OK.

Adjust multiple variables

To experiment with adjusting multiple variables within one scenario, the steps are the same as above, with the exception that the desired changes would be made in the Scenario Values window.

For example, to get Excel to perform a what if analysis on borrowing $50,000 over a 36-month period in the above situation at the same rate of interest, we would simply adjust the fields referencing those variables after creating a new scenario. Excel’s Scenario Manager can handle an unlimited number of scenarios created in this same way. 

A list of created scenarios can be viewed by clicking OK from the Scenario Values window, or by selecting Scenario Manager from the What If Analysis dropdown menu.

What if analysis Excel - scenario managerTo see the outcome of each adjustment on the output cell(s), either double click on a scenario name, or highlight a name and click Show.

Scenario summary

Scenarios that have been created may also be compared side by side with the creation of a Scenario summary worksheet, which is generated by selecting ‘Summary’ from the Scenario Manager window. 

There are two report types available — Scenario summary and Scenario PivotTable report. Result cells are the cells that will be displayed in the summary. Ideally, these should include all cells which were adjusted as well as result cells. It’s also a good idea to select cells that contain header names so that these are clearly displayed in the summary.

What if analysis Excel - scenario managerChoosing the ‘Scenario summary’ option will create a new sheet within the workbook that displays each scenario in columnar format. Changing Cells are highlighted in gray, and Result Cells are displayed under Changing Cells.

What if analysis Excel - scenario summaryNote that if named ranges were created for Changing or Result Cells, range names will be displayed instead of cell references.

Selecting the Scenario PivotTable report type will create a pivot table report in a new worksheet. Learn more about pivot tables from our Resource Library.

Using data tables for what if analysis

The third what if analysis tool from the Forecast command group is the Data Table. Data tables allow the adjustment of only one or two variables within a dataset, but each variable can have an unlimited number of possible values. Data tables are designed for side-by-side comparisons in a way that makes them easier to read than scenarios, once they are set up correctly.

Data tables are under-utilized, but are not as scary as they may seem.

One-variable data tables 

If the only variable to be considered in our loan example were the amount being borrowed, we could set up a one-variable data table.

Step 1 — make a list of all possible principal loan amounts. The list may be by column or row. In our example, we will enter a column list in the range D9 to D12.

What if analysis Excel - data tableStep 2 — In an adjacent column, enter the formula which was used to arrive at the original outcome. In this case, we can simply type =B6 in cell E8. This links our new data table to the original variables. 

What if analysis Excel - data tableStep 3 — Select the entire data table range, including the list of variable values, the formula, and blank cells. 

Step 4 — From the What If Analysis dropdown menu, select Data Table. 

Step 5 — In the column input cell field (since we entered our variables in column format), enter the cell reference that was used to calculate the result in the original dataset. In the above example, this would be cell B1 since this is the variable we have adjusted. No value is entered in the ‘Row input cell’ field in this instance since this is a one-variable data table.

What if analysis Excel - data tableStep 6 — Select OK. The result is a list of outcomes created by adjusting the one variable in cell B1, assuming that all other variables remain constant.

What if analysis Excel - data tableTo create a row-oriented data table, the variables would be listed horizontally, and the row input cell would be used in the Data Table window instead of the column input cell.

Two-variable data tables

When creating a two-variable data table, one set of values is listed horizontally and the other set is listed vertically. In our example, we will add the loan period (term) as our second variable, displayed horizontally.

In this case, the formula which was used to arrive at the original outcome must be replicated above the vertical list of variables. As shown below, we type =B6 in cell D7. This links our new data table to the original variables. 

What if analysis Excel - data tableAs before, highlight the entire data table range and select Data Table from the What If Analysis menu. The row input cell is the cell reference (B3) that corresponds to the horizontal variables from the original dataset, while the column input cell (B1) corresponds to the vertical variables.

When we select OK, Excel returns a matrix that can be used to compare the outcome of different changes to our original scenario. It may be necessary to adjust the output cells to the appropriate number format for your data type (in the case of the above example, currency).
