How ROI Is Calculated
Return on investment expresses your gain as a percentage of what you put in, which makes it possible to compare returns across completely different investments — a rental property against a stock portfolio, for instance. Adding a time period lets you also see the annualized figure, since a 30% return over five years performs very differently from a 30% return in one.
Formula Used
Net Gain = Final Value − Amount Invested
ROI (%) = (Net Gain ÷ Amount Invested) × 100
Annualized ROI (%) = ((Final Value ÷ Invested)^(1/Years) − 1) × 100
Frequently Asked Questions
What's a good ROI?+
It depends entirely on the asset class and risk involved. Stock market returns have historically averaged around 7–10% annually, while higher-risk ventures may target much higher returns to compensate.
Why does annualized ROI matter?+
Total ROI ignores how long your money was tied up. Annualizing the return lets you compare a 3-year investment fairly against a 1-year one, or against a savings account's annual interest rate.
