This tool calculates the Compound Annual Growth Rate (CAGR) of an investment between two points in time. Enter the beginning value, ending value, and the number of years, and it returns the smoothed annualized rate of return — the constant rate that would take you from the starting value to the ending value over that period.

CAGR is the standard metric for comparing investments with different time horizons or volatile year-to-year returns. Unlike a simple average return, CAGR accounts for compounding, so it accurately reflects the actual annualized growth an investor experienced.

Use it to evaluate portfolio performance, compare mutual funds and ETFs, benchmark business revenue growth, or measure how a single position has grown since you bought it. CAGR is especially useful when you need a single number to summarize multi-year performance.
