Get percent change

Excel formula: Get percent change
Generic formula 

If you need to calculate the percentage change between two values in Excel, you can use a formula that divides the change itself by the "old" value. A classic example would be to calculate the percentage between sales last month and sales this month.

How the formula works

In the example, the active cell contains this formula:


In this case, Excel first calculates the difference between the values (the actually change in sales) then divides that result by the original, or "old" value to get the decimal value -0.3435:


Note: you must format the result using Percentage number format to display the final result as -34%
