Percent Decrease Calculator for Students

The following free Percent Decrease Calculator can be used for calculating percent decrease between two numbers (a starting value and a final value) as a percentage.

To use the calculator, simply enter the starting value and the final value and press ENTER or DONE to calculate the percent decrease.

The percent decrease calculator performs the following 3 steps:

  • Find the difference of the values by subtracting the final value from the starting value

  • Divide that difference by the starting value

  • Multiply the result by 100

*Note that for any percent decrease problem, the final value will be smaller than the starting value.

What is the percent decrease formula?

You can always use the percentage decrease formula to solve any problem where you have to calculate the percent decrease between a starting value and a final value.

Again, in any percent decrease problem, the final value must be smaller than the starting value (otherwise, it would be a percent increase problem).
