How to use CAGR Calculator
This CAGR calculator finds the compound annual growth rate that takes an investment from a beginning value to an ending value over a set number of years, using CAGR = (ending divided by beginning)^(1 divided by years) minus 1. It expresses uneven growth as one smooth yearly rate, making different investments easy to compare. Investors and analysts use it to gauge performance over time.

- 1Enter the initial value of the investment.
- 2Enter the final value and the number of years held.
- 3Read the compound annual growth rate shown as a percentage.
Fair comparison
Turns total returns into an annualized rate so different holdings line up side by side.
Smooths volatility
Reports one steady yearly figure regardless of how bumpy the actual path was.
Simple inputs
Only the start value, end value and years are needed to get the answer.
Compare two investments fairly
One holding doubled in 5 years, another in 8 — which actually grew faster? Total return alone hides that. Enter each investment's start value, end value and years to get a single annualized CAGR for both, so you can line up a stock, fund and savings account on the same yearly-rate basis and see which truly outperformed.
Find a stock or fund's annual return
Know what a stock or mutual fund was worth when you bought it and what it's worth now? Enter the purchase price, current price and the number of years held to get its compound annual growth rate. This smooths volatile up-and-down years into one steady percentage — the figure prospectuses quote as annualized return.
Calculate a business's revenue growth rate
Track yearly revenue, users or profit growth for a pitch deck or report. Enter the figure from the first year, the latest year, and the years between to get the CAGR — the standard metric investors expect. It works for any metric and goes negative automatically if the ending value fell, showing an annualized decline.
CAGR Calculator — frequently asked questions
What is the CAGR formula?
CAGR equals (ending value / beginning value) raised to the power of (1 / number of years), minus 1, expressed as a percentage. It is the constant rate that would compound the starting amount into the ending amount over the period.
How is CAGR different from average annual return?
A simple average just adds yearly returns and divides them, ignoring compounding. CAGR accounts for compounding and reflects the true geometric growth rate, so it is usually lower than a simple average when returns fluctuate.
Can CAGR be negative?
Yes. If the ending value is lower than the beginning value, the rate is negative, showing an annualized loss. The formula still applies the same way.
