How the cagr calculator works
The compound annual growth rate is CAGR = (ending ÷ starting)^(1/years) − 1. It’s the constant annual rate that would take the start value to the end value over the period, smoothing out the ups and downs so you can compare investments of different lengths.
CAGR hides volatility — it says nothing about the bumpy path in between, only the start and end. Educational — not financial advice.
Frequently asked questions
How do I calculate CAGR?
CAGR = (ending value ÷ starting value)^(1/years) − 1. Growing $10,000 to $18,000 over 5 years is (1.8)^(0.2) − 1 ≈ 12.5% per year.
What is CAGR used for?
To express an investment’s growth as a single annual rate, so you can compare returns over different time periods on an equal footing.
How is CAGR different from total return?
Total return is the overall percentage gain; CAGR is the equivalent smoothed annual rate. A 80% total return over 5 years is a CAGR of about 12.5%.
Does CAGR account for volatility?
No — it only uses the start and end values, ignoring the path between. Two investments with the same CAGR can have very different risk.
Can CAGR be negative?
Yes — if the ending value is below the starting value, CAGR is negative, showing an average annual loss.
