CAGR Calculator is a browser-based way to work out the compound annual growth rate. Feed it your beginning value, ending value and number of years and it computes the annualised return on the spot, keeping your data local.
Estimate only. Not financial, investment, tax, retirement, pension, crypto, or legal advice. Returns, rates, fees, taxes, inflation, market prices, product rules, and government schemes can change. Verify with official sources or a qualified professional before relying on results.
About this calculator
With the CAGR Calculator you can work out the compound annual growth rate in a few seconds. Supply your beginning value, ending value and number of years and read the annualised return, computed via (ending ÷ beginning)^(1/years) − 1. The tool is free, runs locally, and keeps every value on your machine.
How to use
- Enter the beginning value at the start of the period.
- Enter the ending value at the close of the period.
- Set the number of years between the two values.
- Tap Calculate to see the compound annual growth rate.

Technical notes
CAGR Calculator computes the compound annual growth rate, CAGR = (ending value ÷ beginning value)^(1/years) − 1.
Uses the start value, end value and period you enter to compute the annual growth rate; past growth doesn't predict future returns.
Because it runs locally, results appear instantly with no server round-trip.
Worked example
Growing from 100,000 to 200,000 in 5 years: CAGR = (200,000/100,000)1/5 − 1 = 14.87%.
FAQ
What is the CAGR formula?
CAGR equals the ending value divided by the beginning value, raised to the power of one over the years, minus one, expressed as a percentage.
Does the CAGR Calculator send my data to a server?
No. The CAGR Calculator runs entirely in your browser with JavaScript; the values you enter never leave your device and nothing is uploaded or saved.
Why use CAGR instead of total return?
CAGR converts total growth into a per-year rate, so investments held for different lengths of time can be compared on equal terms.
Does CAGR reflect year-to-year volatility?
No. It assumes smooth, steady growth and hides the ups and downs along the way, so two very different paths can share the same CAGR.
