Percentage Increase Calculator
Find the percentage increase from an original value to a larger new value.
Example
Going from 80 to 100 is a 25% increase because the gain of 20 is one quarter of 80.How do you calculate percentage increase?
To calculate a percentage increase, subtract the original value from the new value, divide that difference by the original value, then multiply by 100. The formula is: percentage increase = (new value − original value) ÷ original value × 100.
Example: a price rising from 80 to 100 is a 25% increase, because the gain of 20 divided by the original 80 equals 0.25, or 25%. If the result is negative, the value actually decreased.
