(0.00 - 0.00) / 0.00 × 100

How to use this calculator?

1. Enter the initial value

2. Enter the final value

3. The evolution rate is calculated automatically

Quick answer

How do you calculate percentage change between two values?

Percentage change is the difference between the final value and the initial value, divided by the initial value, then multiplied by 100. Formula: (final value - initial value) / initial value × 100. Example: revenue rising from 200 to 250 gives (250 - 200) / 200 × 100 = +25%. A negative result means a decrease.

About the Evolution Rate

What is it?

The growth rate calculator measures the relative change between two values over time: revenue growth, traffic evolution, KPI variation...

Why use it?

The growth rate is the basic indicator for measuring business performance. It lets you communicate clear, time-comparable results.

How does it work?

Formula: Growth rate = ((Final value - Initial value) ÷ Initial value) × 100. A positive result indicates growth, a negative result indicates a decline.

Usage tips

  • Always compare identical periods (month vs month, year vs year)
  • Be wary of base effects: a big drop last year inflates the growth rate this year
  • For rapidly growing monthly revenue, also calculate the CAGR (compound annual growth rate)
  • A positive growth rate on a small volume may be less significant than it appears
