How to use
- Choose “% increase between two values” or “Increase a value by X%”.
- Enter the original value and the new value (or the percentage).
- Read the percentage and absolute increase.
How it works
Percentage increase = (new − original) ÷ original × 100. The original value is always the reference, which is why going from 50 to 100 is a 100% increase while going from 100 to 50 is only a 50% decrease.
To increase a value by p%, multiply it by (1 + p ÷ 100): 2,400 increased by 7% = 2,400 × 1.07 = 2,568.
Examples
- Salary raise
- 2,400 → 2,568 = +7%.
- Rent
- 750 → 800 = +6.67%.
Common uses
- Salary negotiations
- Price rises and rent increases
- Growth in sales, traffic or followers

Frequently asked questions
What if the original value is zero?
A percentage increase from zero is undefined, because you can't divide by zero.
Is percentage increase the same as percentage points?
No. A rate rising from 2% to 3% is a 1 percentage-point increase but a 50% increase.
