What is the Percent Change Formula?

The percentage change formula is:


It's straightforward to find the percentage change with a start and final value.

  1. Subtract the final number from the first number (this might result in a negative - that is fine)
  2. Divide the result by the initial number
  3. Multiply by 100

The number that you are left with is the percentage change from the first to second. Next, let's walk through the calculation together.

Percent Change Formula Example

Now, let's work an example.

If your initial number was 200 and your final number was 250, that's a 25% increase. Let's walk through the formula:

(\frac{250-200}{200})*100 \\ \frac{50}{200}*100\\.25*100=25\%
