# How to Use a Percentage Formula in Excel

In this short how-to tip, we will see how you can use a percentage formula in Excel.

Below, you can see an example of an Excel spreadsheet, that contains some sample values, based on which we will create a percentage formula.

As you can see, the spreadsheet has 3 columns:

• Month/Year
• Sales
• Growth Percentage

What we need to do know, is to calculate the values for the column “Growth Percentage”.

To this end, we need to find the proper percentage formula, that will be calculating the growth percentage of sales between months, based on the given scenario. ## Finding the Percentage Formula

So, the percentage formula, for finding the growth percentage of sales between months, would take the sales amount for a given month and then divide this value to the sales value of the previous month. Then, the result of this division can either be manually multiplied by 100 for giving the final percentage value, or if you select the Excel cell and click on the percentage icon, Excel will do this for you.

So let’s see the below example, where we implement this logic: As you can see in the above screenshot, for cell C2, it is not applicable to calculate the growth percentage of sales, since there is not a preceding month. Therefore, we begin by setting the formula for cell C3.

To this end, as you can see in the above screenshot, the formula is to divide the value of C3 (that is the sales of Feb-21), by the value of the previous month, that is cell B3 (sales of Jan-21).

If we apply this formula, this is what we get: So, now you can see, that the result of the formula for C3 is 1.5, which actually means 150%.

Now, in order to set the relevant formula for the rest of the cells, we click on the little green square rectangle on our formula, and then we hold and drag the fill handle down the column over the cells where we want to copy the formula, that is in our example, up to cell C7.

Along with the above action, we click on the percentage icon on the ribbon menu, while we have select all cells between C3 and C7, and right after we click, the values are transformed to actual percentage values as per the below screenshot. ## Featured Online Courses:
