CAGR Calculator

You cannot just divide total growth by the number of years — growth compounds, so the annual rate needs a root, not a division.

Your numbers

CAGR

19.14%

Total growth

140%

Formula

CAGR = ((After ÷ Before) ^ (1 ÷ Years) − 1) × 100

140% over five years is 19.14% a year, not 28%. Dividing overstates the yearly rate.

What to enter
