How This Calculator Works
CAGR (Compound Annual Growth Rate) measures the smoothed, year-over-year growth rate an investment would need to grow from its starting value to its ending value over the given period, assuming steady compounding — even if the real growth was uneven year to year. Formula: CAGR = (End Value / Start Value)^(1/Years) − 1.
FAQ
How is CAGR different from average annual return?
A simple average of yearly returns can be misleading when returns are volatile (a 50% gain followed by a 50% loss doesn’t average to 0% actual growth). CAGR instead measures the single, smoothed compounding rate that actually connects the start and end values.
Does CAGR account for volatility along the way?
No — it only looks at the start and end values, ignoring what happened in between. Two investments with the same CAGR can have had very different, and very differently risky, paths to get there.
