CAGR answers: "If value grew smoothly at the same rate every year, what yearly rate would take me from start to end?" Enter your beginning amount, ending amount, and the number of years. The result is an annualized percentage useful for comparing long horizons; it ignores path volatility and cash flows in between.
CAGR = ((end ÷ start)^(1 ÷ years) − 1) × 100 with continuous compounding-style smoothing across the whole span—one rate that would take start to end in exactly years. No cash flows in between; start/end must be positive.
This calculator uses plain decimal numbers. If a result looks wrong, check whether you used a comma instead of a dot (or vice versa) where the field expects one.
