📈 ROI Calculator
Estimate investment gain, total ROI, and annualized ROI from your total cost, final value, and holding period. Educational estimate only; not investment advice.
Amount inputs support up to 2 decimal places. Holding period supports whole months or whole years only. If your holding period is 18 months, enter `18` and choose Months; do not enter `1.5 years`.
Total ROI reflects the return over the full holding period. Annualized ROI only converts that return into a per-year equivalent and does not imply the same result will repeat every year in the future.
Results on this page do not automatically include taxes, inflation, risk, leverage, dividend reinvestment, rent, or any other interim cash flows. If those matter to your scenario, include them in your inputs manually or use a more complex model.
Result amounts stay in your input currency unit. Interpret both the on-page values and copied results in that same currency context; this tool does not perform FX conversion or force USD/CAD labels.
Disclaimer: This tool is for educational estimation only. It is not investment, financial, legal, or tax advice, and it is not a return forecast, guarantee, recommendation, or risk rating. Results depend on your inputs and the current formula model, and only reflect the mathematical relationship between total cost, final amount returned, and holding period.
Privacy note: Calculations run locally by default. Your numeric inputs are not uploaded.
