How to use CAGR Calculator
- Enter a positive starting value and the ending value.
- Enter the elapsed years, including a decimal if needed.
- Review the annualized rate and endpoint growth.
Example: CAGR Calculator
Starting value 1000, ending value 1500, elapsed years 5.
You add
Starting value 1000, ending value 1500, elapsed years 5.
You get
CAGR is approximately 8.447177%.
Supported inputs and limits
Starting value must be positive; the ending value may be zero. Years must be greater than zero and at most 100. Additional deposits, withdrawals and intermediate volatility are outside this endpoint model. Enter plain decimals with at most 64 characters, 25 digits and 12 fractional places. Monetary inputs are limited to 10^12. Very small or large nonzero amounts use scientific notation. Use one currency throughout; no exchange rates, taxes or fees are added unless you enter them.

A rate between endpoints
CAGR = (ending / starting)^(1 / years) - 1. Both amounts must describe comparable values over the same elapsed interval.
Questions about CAGR Calculator
Does CAGR show each year’s actual return?
No. It is the constant rate that connects the two endpoints, even when the actual path varies.
Can I use a zero ending value?
Yes. A positive start reduced to zero gives a CAGR of -100%. A zero starting value cannot define this ratio.
What happens with added contributions?
The tool does not adjust for them. Contributions change the endpoint, so this rate may not represent investment performance.
