CAGR Calculator
CAGR: it computes the compound annual growth rate, CAGR = (ending value ÷ beginning value)^(1/years) − 1. Worked through below with real figures, and the calculator repeats the working on your own inputs — free, on-device, instant.
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
CAGR is easiest to get wrong in the setup, not the arithmetic. It computes the compound annual growth rate, CAGR = (ending value ÷ beginning value)^(1/years) − 1. It matters any time money changes value over time — savings, loans, investments, prices and pay all reduce to these relationships. The worked example on this page (Growing from 100,000 to 200,000 in 5 years: CAGR = (200,000/100,000) 1/5 − 1 = 14.87% .) shows the full substitution; the calculator above runs the same working on your own numbers, in your browser, with nothing uploaded.
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.
Why use the CAGR Calculator
Instant
Every figure is computed on your device the moment you tap Calculate.
Private
Your numbers stay in your browser; nothing is sent to a server or saved.
Free
No signup, no paywall, and no ads placed inside your results.
Works offline
Once the page has loaded it keeps working even on a weak connection.
Mobile-first
Laid out for phones and tablets just as much as for desktops.
Honest estimates
Uses simplified formulas for educational estimates; actual results vary with taxes, fees, compounding rules, market returns, scheme rules, inflation, and local regulations.
Common uses
Use it when comparing growth across periods
Use it when annualising a multi-year return
Use it for a quick growth-rate check
Use it for a beginning-to-ending value over years
Use it when reviewing a fund's long-run return
Use it for a year-on-year growth summary
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.
