ROI Calculator
Return on a gain versus cost.
Loading tool
Enter what you spent and what you got back, plus how long you held it. Percentages are estimates, not a performance report.
How to use this tool
- Enter the amounts. Fill in principal, rate, term, or prices. Use the same currency throughout.
- Read the estimate. The figures are a simplified model, not a lender or tax quote.
- Compare a related tool. Open amortization, compound interest, or paycheck if you need another view.
Annualized figure
CAGR-style annualization assumes a smooth path. Real investments jump around. Taxes and fees are omitted unless you net them in the inputs.
Frequently asked
Should I include dividends?
Add them to proceeds if you want a total-return estimate.
Can I compare two projects?
Run each separately. This page does not rank a portfolio.
Is a high ROI always better?
Risk, time, and cash timing matter. This tool does not judge that.
Should I buy or sell based on this ROI?
No. The percent is an estimate from two cash figures, not a recommendation.
Does it use XIRR?
No. Cash flows are a single in and a single out.
