About this tool
Compound annual growth rate between a starting and ending value over any period, with absolute return and doubling time.
CAGR is the single constant yearly rate that would carry a starting value to an ending value over a given period, calculated as (end ÷ start)^(1 ÷ years) − 1. This calculator returns that rate along with the absolute return, the growth multiple, and the number of years the money would take to double at the same pace. Investors, founders and analysts use it to compare holdings of different sizes and holding periods on one scale.

Uses the compounding identity rather than dividing total gain by years, so the rate actually reproduces the ending value.
Enter a plain number of years, or two calendar dates and let the fractional period be worked out for you.
Applies t = ln 2 ÷ ln(1 + r) so you can see how long the same rate needs to double your money.
Divide the ending value by the starting value, raise the result to the power of 1 divided by the number of years, then subtract 1. For example, ₹2,50,000 growing to ₹10,00,000 over 10 years gives (4)^(1/10) − 1 = 14.87% a year.
Absolute return is the total percentage gain over the whole period, while CAGR spreads that gain across the years with compounding. A 100% absolute return over 5 years is a CAGR of 14.87%, not 20%.
No — it depends on the asset class and the period. Broad equity indices have historically compounded in the high single to low double digits over long stretches, while cash and bonds sit far lower; judge any figure against a relevant benchmark over the same window, not in isolation.
Yes. If the ending value is lower than the starting value the rate is negative, and if the investment ends at zero the CAGR is exactly −100%. Negative CAGR simply means the value shrank at that compounded rate each year.
