How to use

  1. Choose “% increase between two values” or “Increase a value by X%”.
  2. Enter the original value and the new value (or the percentage).
  3. 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.
