ROI
What Is ROI?
ROI (Return on Investment) is one of the most widely used financial metrics for evaluating the profitability of an investment.
It tells you how much money you've earned — or lost — relative to the amount you originally invested. The higher your ROI, the better your investment has performed.

ROI Formula
The standard ROI formula is:
ROI (%) = ((Final Value − Initial Investment) ÷ Initial Investment) × 100
- Initial Investment = Amount invested
- Final Value = Current value or sale price
- ROI = Percentage return
Example ROI Calculation
Suppose you invest an Initial Investment of $10,000, and it grows to a Final Value of $13,000. That is a profit of $3,000.
ROI: (($13,000 − $10,000) ÷ $10,000) × 100 = 30%. Your investment generated a 30% Return on Investment.

Frequently Asked Questions
What is a good ROI?
A "good" ROI depends on the type of investment and your risk tolerance. Generally, a positive ROI indicates a profitable investment.
Is ROI always accurate?
ROI is an excellent starting point but does not consider investment duration, inflation, taxes, or risk.
Can I calculate marketing ROI?
Yes. The calculator is useful for measuring advertising and digital marketing campaign performance — use total spend as the initial investment and revenue generated as the final value.
Does ROI include taxes?
Typically, no. You should account for taxes and transaction costs separately, or add them as additional costs in the calculator.
Can I compare different investments?
Absolutely. ROI is commonly used to compare multiple investment opportunities before making a decision.
Is this ROI Calculator free?
Yes. CalcWisee offers this calculator completely free, with no sign-up or account required. You can calculate return on investment for any combination of initial cost and final value as often as needed, and nothing you enter is stored or transmitted — all maths runs locally in your browser.
How is ROI different from annualized return?
ROI measures total return over the entire holding period, while annualized return spreads that gain evenly across each year — useful when comparing investments held for different lengths of time.
What counts as a cost in the calculation?
Any fees, commissions, taxes, or maintenance expenses tied to the investment should be included as additional costs for an accurate net ROI.
