How ROI is Calculated
Return on investment (ROI) measures how much profit you earned relative to how much you spent. It is used to evaluate stocks, business campaigns, real estate deals, and other financial decisions.
ROI formula
ROI = (Net Profit / Total Cost) * 100
Net Profit = Final Value - Total Cost, where Total Cost = Initial Investment + Additional Costs.
Annualized ROI adjusts your return for time using the CAGR formula, so you can compare investments held for different periods.
Investment multiple (MOIC) shows the final value as a multiple of total cost. A 1.35x multiple means every $1 invested became $1.35.
Include fees, commissions, and related costs for a realistic ROI estimate. Excluding costs usually overstates performance.
Frequently Asked Questions
Common questions about ROI, annualized returns, and interpreting results.
ROI is total return over the full period. Annualized ROI converts that total return into an equivalent yearly rate, which is better for comparing investments held for different lengths of time.
Yes. Fees, commissions, and related costs reduce real returns. Include them in Additional Costs so ROI reflects what you actually earned, not a gross estimate.
Yes. Negative ROI means you lost money overall. This calculator supports loss scenarios and displays negative results in red for quick interpretation.
ROI is a simple total-return ratio. IRR accounts for timing across multiple cash flows and is better for complex projects. For single-entry, single-exit scenarios, ROI is usually sufficient.
