How to find a percent of change

To calculate the percentage increase:

   First: work out the difference (increase) between the two numbers you are comparing.

   Increase = New Number - Original Number.

   Then: divide the increase by the original number and multiply the answer by 100.

   % increase = Increase ÷ Original Number × 100.
