Measure the profitability of your investments with our free ROI calculator. Perfect for evaluating marketing campaigns, business projects, or personal investments.
Calculate your return on investment
ROI commonly means (gain from investment − investment cost) ÷ investment cost × 100.
Enter the investment amount and the return or gain according to the calculator’s definitions.
Be clear about whether revenue, profit, cash flow, fees, or another measure is being treated as the return.
ROI is a ratio and does not automatically account for time. Two investments with the same ROI can have very different durations.
Use it to compare campaigns, projects, purchases, or investments when the inputs are measured consistently.
Different ROI results often come from different definitions of cost and return, inclusion of fees, or different time periods.
