About the ROI Calculator
The ROI Calculator measures the profitability of an investment as a percentage of the money invested, and annualizes it over the holding period.

ROI = (Return − Investment) ÷ Investment. Annualized ROI = (1 + ROI)^(1/Years) − 1.
ROI = (Gain / Cost) × 100%
Annualized ROI = (End/Start)^(1/Years) − 1How to use this calculator
- Enter the amount invested.
- Enter the amount returned (or current value).
- Enter the holding period in years for annualized ROI.
Example
$10,000 invested, worth $16,000 after 4 years, is a 60% total ROI or about 12.5% annualized.
Frequently asked questions
What is a good ROI?
For public equities, 7–10% annualized is average. Higher expected ROI generally means higher risk.
Should I use gross or net returns?
Net of fees, taxes, and inflation gives the most realistic ROI for personal finance decisions.
Is ROI the same as profit margin?
No. Profit margin is profit ÷ revenue; ROI is profit ÷ investment. They answer different questions.
