CAGR = (end/start)^(1/years) -1; Total return = (end-start)/start

How does this work?

CAGR smooths annual growth over years, assuming compounding. It is end divided by start to the power of one over years, minus one. Total return is simple percent change.

Use CAGR to compare investments with different horizons. It hides volatility — two investments with same CAGR can have very different risk.

For YMYL investment comparisons, pair CAGR with volatility and drawdown, not alone. Past CAGR does not guarantee future.

What is Compound Annual Growth Rate?

CAGR smooths annual growth over years, assuming compounding. It is end divided by start to the power of one over years, minus one. Total return is simple percent change. Formula: CAGR = (end/start)^(1/years) -1; Total return = (end-start)/start

Quick Answer

Compound Annual Growth Rate Calculator computes calculate cagr from start and end values over years — see annual growth rate, total return and doubling time. Formula: CAGR = (end/start)^(1/years) -1. Example: With $10k to $25k in 5 years: total return 150%, CAGR about 20.

Frequently Asked Questions

QCAGR vs average?

CAGR is geometric, accounting for compounding. Arithmetic average overstates when volatile.

QNegative?

If end < start, CAGR negative, showing annual decline. Total return also negative.

QDoubling time?

72 divided by CAGR percent approximates doubling years at that rate.
