What is the ROI Calculator?
A positive ROI is a gain relative to cost; a negative ROI is a loss.
The Calcwise ROI tool is designed to give a fast answer while keeping the arithmetic visible. Enter the requested values, check the units, and the result updates in your browser. Your calculator entries are not sent to a Calcwise server.
How to use this calculator
- Enter values using the units shown beside each field. In the interactive calculator, each field also shows a plain-language example or meaning guide.
- Check that the values describe the same period or situation where relevant.
- Read the main result and the supporting figures shown beside it.
- Use the reset button to return to the example values.
Inputs used
- Initial cost — Amount invested or spent
- Final value — Current value or amount returned
ROI Calculator formula
The formula is shown so you can understand the relationship between the inputs instead of treating the result as a black box.
Worked example
A cost of ₹1,00,000 and final value of ₹1,25,000 gives a 25% ROI.
Your own result may differ because it uses the exact values you enter. For comparisons, keep the method and units consistent from one calculation to the next.
Important assumptions and limitations
ROI does not account for time, risk, taxes, fees or additional cash flows. Use CAGR when the holding period matters.
Calculator outputs are estimates unless the underlying arithmetic is exact by definition. For decisions involving tax filing, lending, health, contracts or institutional grading rules, use the calculator as a first check and confirm the final decision with the relevant authoritative source.
