How it works
Total ROI is (returned − invested) ÷ invested × 100. Annualized ROI (CAGR) is (returned ÷ invested)1/years − 1, which spreads the gain evenly across the holding period so a 3-year deal and a 1-year deal can be compared apples-to-apples.
Frequently asked questions
What is a good ROI?
It depends on the asset. The stock market has averaged roughly 7–10% per year after inflation; real estate investors often target higher to compensate for effort and risk. Compare against what else you could do with the money.
Why does annualized ROI matter?
A 50% total return sounds great — but over 5 years it's only ~8.4% per year. Annualizing reveals the true pace of growth and lets you rank opportunities fairly.
What does ROI miss?
Risk, timing of cash flows, taxes, and your time. Two investments with identical ROI can feel very different if one paid out monthly and the other locked your money up for a decade.
