Direct Answer: To calculate Return on Investment (ROI), subtract your initial investment cost from the final value, divide that net profit by the initial cost, and multiply by 100. For multi-year horizons, calculate annualized CAGR to benchmark performance accurately.
This free tool provides a quick, transparent estimate for measuring return on capital, net profitability, and annualized investment gains.
ROI = ((Net Profit) / Initial Investment Cost) × 100%

This calculator estimates your Return on Investment (ROI), net profit, and annualized growth rate using standard financial formulas. We are committed to transparency—here is exactly how it works.
Your total ROI is calculated using the standard formula:
ROI = ((Gain from Investment – Cost of Investment) / Cost of Investment) × 100
Where:
The calculator also calculates annualized ROI (CAGR) when you provide the number of years held:
Annualized ROI = [(1 + Total ROI)^(1/n) – 1] × 100
Where n = number of years the investment was held.
This calculator uses the following assumptions:

Return on Investment (ROI) measures the financial efficiency and profitability of an investment or business expenditure relative to its capital cost.
ROI = [(Final Value - Initial Cost) ÷ Initial Cost] × 100| Variable | Description & Context | Measurement Unit | Sample Input |
|---|---|---|---|
Amount Invested / Initial Cost |
Amount Invested / Initial Cost ($) | $ | 10000 |
Amount Returned / Final Value |
Amount Returned / Final Value ($) | $ | 15000 |
Investment Time Horizon |
Investment Time Horizon (Years) | Years | 3 |
Understanding these foundational concepts ensures you interpret your results with precision:
Return on Investment (ROI) is the universal metric for comparing competing capital investments across stocks, real estate, technology upgrades, and business ventures.
Simple ROI ignores the passage of time. A 50% return over 1 year is exceptional (50% CAGR), whereas a 50% return over 10 years is only 4.14% CAGR, trailing conservative index funds. Always evaluate ROI in relation to time horizon and risk profile.
If you're analyzing marketing efficiency, compare your ROI with our dedicated ROAS Calculator to separate campaign performance from overall profitability.
When evaluating a capital purchase, use our Loan Calculator to model the impact of financing on your cash flow.
Before deploying capital, establish your required hurdle rate—the minimum acceptable return considering inflation and alternative risk-free yields like Treasury bills.
Example: Invest $10,000, Return $15,000 over 3 years = Total ROI 50.00%, CAGR 14.47%/year
