CAGR Calculator
Find the Compound Annual Growth Rate (CAGR) of your investments over any period of years.
Understanding CAGR (Compound Annual Growth Rate)
CAGR, the compound annual growth rate, is the single steady annual rate at which an investment would have had to grow, compounding every year, to turn its starting value into its ending value. The formula is (final value / initial value)^(1 / years) - 1, and its job is to make investments held for different lengths of time comparable. If ₹1 lakh becomes ₹2.5 lakh in 5 years, the CAGR is about 20.1%: not because the fund rose exactly 20.1% each year, but because that steady rate reproduces the same end value.
CAGR is not the same as absolute return, which measures the total change ignoring time: ₹1 lakh growing to ₹2.5 lakh is a 150% absolute return, whether it took 5 years or 10. Annualising is what makes comparisons fair: that 2.5x works out to a 20.1% CAGR over 5 years but only about 9.6% over 10. For a one-time investment such as a lump sum, CAGR is usually the headline number, and the calculator shows the absolute return alongside it.
Two limitations are worth knowing. CAGR assumes a single investment at the start and a single value at the end, so it cannot digest money added or withdrawn in between, a SIP needs XIRR instead, computed by the sibling XIRR calculator; our guide to CAGR vs XIRR explains when each measure applies. And CAGR is a nominal figure: a 12% CAGR with 6% inflation works out to only about a 5.7% real return, which is the part that actually grows your purchasing power.
