In this article, we will see the formula to calculate the percentage difference between two Numbers in Excel. There is basically one formula to calculate this which is, % of Difference = (New Value-Old Value)/Old Value. Normally after applying this formula, we multiply the result with 100 to get the percentage of difference. But in Excel, you don’t need to multiply 100 with the resultant number. There is a built-in feature available in Excel which automatically formats a number into a percentage.
Calculate Percentage Difference Between Two Numbers
As I stated, the formula to calculate the percentage of difference is, % of Difference = (New Value-Old Value)/Old Value. After applying this formula, you will get your result in number format. So, you have to format it into a percentage to get the actual result. This formula actually provides the result of percentage increase. So, if you get a negative value it means, instead of getting the percentage of increase you will get the percentage of decreases result.
Look into the above picture. Here although we applied the percentage of difference formula, the result is not in the percentage format. To get the result in percentage format, select the cells where you want to apply the formatting. After selecting the cells, select the Percentage Style Option which is under the Number section in the Home tab.
After applying the Percentage Style Option, you will get the below result.

Let`s say you want to highlight the percentage of differences such that the positive values get green color and the negative values get the red color. To perform that you need to apply the Custom Number Formatting. First, select the cells where you want to apply this formatting and click on to the right button of your mouse to select the Format Cells option.
After selecting the Format Cells option you will get the Format Cells Dialogue box. In the Format Cells dialogue box select the Custom option and, in the Type filed are write, [Green]+ 0%; [Red]- 0%; 0% and press OK.
