## Evaluate Formula in Excel

When you try to solve complex problems in excel, we might fail most of the time. When we decided to search on the internet, we may get a solution that is readymade, but it is very hard to understand due to the nested formulas they have used.

The good thing is we got the solution that we wanted but not understanding the formula is not a good sign because in the future, if we want to alter or change the references of the formula, we must know how the formula is working.

So, in such situations, it is important to understand the formula, so to understand the formula, we can use the “Evaluate Formula” tool in excel. In this article, we will take you through the process of evaluation of the formula.

**How to Use Evaluate Formula Using F9 Key in Excel?**

As I told to understand big formulas, we need first to understand parts of the formula step by step, and this is called an evaluation of the formula or debugging.

For an example, look at the below formula for this example.

If you don’t understand anything from the formula, we can evaluate part by part by pressing the F9 key.

The F9 key is used to quickly evaluate and debug the formula to understand and efficiently work with excel. Using this F9 key, we can evaluate only the part of the formula by replacing the actual formula with the result of the formula.

#### Example #1

In the above example, we have applied a logical test, i.e. A2>40. Based on the logical test, we are analyzing the price status. If the price is >40, then we need the result as “Costly”, or else we need the result as “Cheap”. So, IF condition tests the logical test and returns “Costly” if the logical test is TRUE or if the logical test is FALSE, it will return “Cheap”.

In cell B2, we have got the result as “Cheap”, to understand how we got this result, let’s evaluate the logical part of the formula.

The formula bar selects only the logical test part of the formula.

Once the logical test part is selected, press the F9 key and see what the result is.

It says “FALSE” because in the A2 cell price value is not >40, so the logical test is FALSE. Since the logical test is FALSE, we got the result as “Cheap”.

Now go to cell B4, where we have the result of “Cheap”. In that cell, select the logical test part and press the F9 key.

Now press the F9 key to see the result of the logical test.

The logical test result is TRUE. Since we have applied the result as “Costly” for the TRUE part, we got the same result in the B4 cell because the price of is A4 cell is >40.

But when it comes to cell B6, we got the result as Cheap even though the price is 40; this is because we have applied the logical test as >40, not >=40.

#### Example #2

Now take a look at one more example of evaluating the formula. Take a look at the below data.

In the below table, we need to check whether the Jan total is equal to the Feb total. If both the totals are equal, we should get the result as “Same” or else “Not Equal”.

I have applied the formula as below.

**=IF(SUM(A2:A6)=SUM(B2:B6),”Same”,”Not Same”)**

I have applied two SUM function to get the total Jan & Feb respectively. Select both the SUM functions equation in the formula.

Press the F9 key and see what the result is.

We got the result as FALSE because Jan total is equal to Feb total. How do you know Jan total is not equal to Feb total???

To check only Jan total, select only the first SUM function and press the F9 key.

So, Jan total is 2062; similarly, evaluate for Feb total.

Feb total is 1909, so the logical test is FALSE, and the result is “Not Same”.

To see the values of the SUM function, considering selecting only the cell range part in the SUM function.

Now press the F9 key; we should see all the values from the cells A2 to A6.

### Evaluate Formula Feature

One more way of evaluating the formula is by using the built-in excel feature “Evaluate Formula” option. This option is available with excel under the FORMULA tab.

To use this feature, select the formula cell that we want to evaluate and click on this feature.

As soon as we click on this button, we get the below window.

Now click on **“**Evaluate**”, **it will evaluate the underlined part.

Click on Evaluate to evaluate the second SUM function.

Both the equations are selected simultaneously, and click on Evaluate; it will show whether the logical test is TRUE or FALSE.

Now the entire formula is selected, so click on Evaluate one last time it will show the final result.

So, the result is “Not Same” because Jan total is not equal to Feb total.

**Things to Remember **

We need to be wary of the F9 key because when we are evaluating the formula, we should just evaluate and press the Esc key; otherwise, it will replace it with calculated results. For example, in the above example, we have evaluated all the cell values.

Now, if I press enter key, we will get the formula as it is.

So, in this aspect of the F9 key, we need to be careful. Once its calculated values or cell values replace the formula, it is no longer a dynamic formula, so this is the one area we need to be careful of while debugging the formula.
