ROI vs CAGR
ROI is the total percentage gain or loss. CAGR is the steady yearly growth rate that would take you from the start value to the end value, which makes investments held for different periods comparable.
ROI = (final − invested) ÷ invested × 100
CAGR = (final ÷ invested)^(1 ÷ years) − 1
Worked example
100,000 grows to 180,000 in 4 years. ROI = 80%. CAGR = 1.8^(1/4) − 1 = 15.83% a year.
ROI ignores time and CAGR ignores volatility along the way, so use both, and remember costs and taxes are not included.
Frequently asked questions
How do you calculate ROI?
Subtract the amount invested from the final value, divide by the amount invested and multiply by 100.
What is a good ROI?
It depends on risk and time. Compare CAGR to alternatives like inflation, deposits and index funds.
Why use CAGR?
It converts total growth into a yearly rate, so a 3-year and a 10-year investment can be compared fairly.
Can ROI be negative?
Yes. A negative ROI means the final value is below the amount invested.
