What is the Percent Difference Formula?

The percentage change formula is:


It's simple to find the percentage difference if you have a start and an end number.

  1. Subtract the end number from the start number (even if the result is negative)
  2. Divide the resulting amount by the start number
  3. Multiply by 100

That resulting number is the percentage difference going from start to finish.

Percent Difference Formula Example

It helps to walk through a real-life example.

If your initial number was 500 and your final number was 750, that's a 50% increase. Here are the steps to compute that:

(\frac{750-500}{500})*100 \\ \frac{250}{500}*100\\.5*100=50\%
