What is ROI?

Annualized ROI = ((Final / Initial)^(1/years) − 1) × 100Annualized ROI is more useful for comparing investments held for different time periods.
Frequently Asked Questions
What's a good ROI?
It depends on the asset class and time period. For stocks, the long-term S&P 500 average is around 7u201310% annually after inflation. Real estate often returns 8u201312%. For business investments, 15%+ is generally considered strong.
Why use annualized ROI instead of total ROI?
Total ROI of 50% over 10 years is much weaker than 50% over 2 years. Annualized ROI normalizes returns into per-year rates so different investments can be compared fairly.
Does this account for taxes or fees?
No. To get net ROI, subtract taxes, transaction fees, and inflation from your final value before entering it. The calculator gives the pure mathematical return.
