ROI Calculator
Use this ROI calculator to compare an investment cost with its ending value and estimate the percentage return. It can help compare simple scenarios, but ROI does not explain timing, risk, taxes, fees, cash-flow quality, opportunity cost, or whether the return was achieved consistently over time.
How to use this calculator
- Enter the original investment cost as the amount spent or committed.
- Enter final value as the ending value of the investment or project, not only the gain.
- Read net profit as final value minus cost, and ROI as that net profit compared with the original cost.
Formula
- Net profit = final value - investment cost
- ROI percentage = net profit / investment cost x 100
Example calculation
If an investment costs $10,000 and is later worth $12,500, net profit is $2,500 and ROI is 25%.
How to interpret the results
- Positive ROI means the final value is higher than the original cost, but it does not show how long the return took or how much risk was involved.
- Compare ROI with net profit, payback period, cash-flow timing, taxes, and alternative uses of the same money.
- Make sure final value is the ending value after the investment, not only the gain.
Frequently asked questions
Is final value the same as profit?
No. This calculator treats final value as the ending amount. Profit is calculated by subtracting the original investment cost from that ending value.
Does ROI include time?
Basic ROI does not show how long the return took. A 20% ROI over one year and a 20% ROI over ten years are very different situations.
Does ROI measure risk?
No. ROI is a simple outcome ratio and does not account for uncertainty, volatility, taxes, or liquidity.
Should I enter gain instead of final value?
No. Enter the ending value. For example, if a $10,000 investment becomes $12,500, enter $12,500 as final value, not $2,500.
