Calculate Percentage Increase In Excel

Introduction to Calculating Percentage Increase in Excel

Calculating percentage increase is a common task in Excel that helps you understand the difference between two values over time. It’s widely used in various fields such as finance, sales, and data analysis. In this article, we will explore how to calculate percentage increase in Excel using formulas and functions.

Understanding Percentage Increase

Percentage increase is the difference between the new value and the old value, divided by the old value, and then multiplied by 100. The formula to calculate percentage increase is: ((New Value - Old Value) / Old Value) * 100. For example, if the old value is 100 and the new value is 120, the percentage increase is ((120 - 100) / 100) * 100 = 20%.

Calculating Percentage Increase in Excel

To calculate percentage increase in Excel, you can use a simple formula. Let’s assume you have two columns, one for the old values and one for the new values.

Old Value	New Value	Percentage Increase
100	120	=((B2-A2)/A2)*100

In the above table, A2 represents the old value and B2 represents the new value. The formula =((B2-A2)/A2)*100 calculates the percentage increase.

Using Functions to Calculate Percentage Increase

Excel also provides functions that can be used to calculate percentage increase. One such function is the PERCENTAGE function, but it’s not directly available in Excel. However, you can use the PERCENTRANK function in combination with other functions to achieve the same result.

Alternatively, you can use the formula =(New Value / Old Value) - 1 to calculate the percentage increase as a decimal, and then multiply by 100 to convert it to a percentage.

Formatting Percentage Increase in Excel

Once you have calculated the percentage increase, you can format the result as a percentage. To do this, select the cell containing the formula, go to the Home tab, and click on the Percentage button in the Number group. This will format the result as a percentage.
