CAGR calculator
Find the constant annual rate connecting two values.
Formula
CAGR = ((end / start)^(1 / years) − 1) × 100%
Compound annual growth ≈ 100×(((1,210)÷(1,000))^(1÷(2))-1) · Total change ≈ 100×((1,210)÷(1,000)-1)
How to use
- Enter positive starting value and nonnegative ending value.
- Enter elapsed years greater than zero.
- Read CAGR and total percentage change.
Examples
- 1,000 growing to 1,210 in 2 years has 10% CAGR.
- 1,000 falling to 810 in 2 years has −10% CAGR.
Frequently asked questions
Does CAGR show each year’s return?
No. It smooths the complete interval into one annual rate.
What if I add or withdraw money?
Those cash flows distort this comparison; use a cash-flow return method.
Can CAGR be negative?
Yes. A lower ending value gives a negative rate; zero ending value gives −100%.
