What is Percentage Increase Calculator?
The Percentage Increase Calculator is a handy online maths tool designed to instantly calculate the percentage by which a value rises from an original (old) amount to a new amount.

It's extremely useful for quickly understanding relative changes in numbers, instead of just the absolute difference.
Formula or Logic Behind Percentage Increase Calculator
The basic formula used for percentage increase is:
Percentage Increase = ((New Value – Original Value) / Original Value) × 100%
This means you first subtract the original value from the new value to get the increase. Next, divide this increase by the original value to find the ratio of change. Finally, multiply by 100 to convert your result into a percentage. If the answer is negative, this means you have a percentage decrease instead.
