How to calculate Percentage Change

To calculate the percent change (percentage increase or percentage decrease), you must first determine the difference between the two numbers you are comparing.

To calculate the percentage increase, you must minus the original number from the new number. E.g.
Increase = Original number - New Number

Then, divide the increaes by the original number and multiply by 100. E.g.
Percentage increase = increase amount ÷ Original Number × 100.

Similarly, to calculate the percentage decrease you must minus the new number from the original number. E.g.
Decrease = New number - original Number

Then, divide the decreaes by the original number and multiply by 100. E.g.
Percentage decrease = increase amount ÷ Original Number × 100.
