How to Find Percent Increase

Percent increase is the change in a value by a percentage and can be found by finding the difference between the current value and the increased value and then adding the difference to the current value. Use the following formula to calculate the increase in a value by a percentage:

y = (value × (percent ÷ 100)) + value

Start by finding the amount to increase the value by multiplying the value by the percentage in decimal form(% ÷ 100). Then add the amount to increase to the original value to find the increased value.

Our percent change calculator can help measure the amount of change in a value.

Example: Increase 80 by 50%

y = (value × (percent ÷ 100)) + value
y = (80 × (50 ÷ 100)) + 80
y = (80 × .5) + 80
y = 40 + 80
y = 120
