Q:

# How do you calculate percentage change in Excel?

A:

Microsoft Excel does not have an automatic function that allows you to calculate percentage change. Despite this, you can find the percentage change between two numbers in a spreadsheet if you know the proper formula to enter into the document. Assuming the two numbers for which you want to find the percentage change are in cells A2 and B2, the formula to use would be =(B2/A2)-1.

For example, let's assume your salary in your first year of employment at a job were \$40,000 and your salary in your second year of employment at the same job were \$50,000. If you were to enter 40,000 into cell A2 and 50,000 into cell B2, you would then select an empty cell on the Excel document and enter the following formula into that cell: =50,000/40,000)-1.

The percentage change in salary from the first year to the second year will appear in the cell as a decimal. To change the decimal to a percentage, right click the cell and choose "Format Cells" from the drop-down menu. When the dialog box opens, choose "Percentage" from the list, then click "OK."

Repeat this process as many times as needed with other numbers for which you want to find the percentage change.
