CAGR Calculator
Calculate the compound annual growth rate between a starting and ending value.
An investment that grew from 1 lakh to 2 lakh sounds like it "doubled" — but whether that took 3 years or 10 years changes everything. CAGR (compound annual growth rate) answers the real question: what steady yearly growth rate would have produced this result? It's the standard way to compare investments, revenue growth, or any metric across different time spans.
Enter the starting value, ending value and number of years, and this calculator returns the CAGR along with the total growth percentage. Use it to compare a mutual fund's 5-year performance against a stock's 3-year run, or to annualize your company's revenue growth for a pitch deck.

Frequently asked questions
Common mistakes to avoid
- Dividing total growth by years (simple average) instead of using the compound formula — this overstates the annual rate.
- Comparing CAGRs over very different periods without noting volatility: a smooth 12% and a wild ride to the same endpoint have equal CAGR.
