What Is ROI?
ROI (Return on Investment) measures how much you make or lose compared to what you put in. It tells you if an investment is profitable for its cost.
ROI is typically expressed as a percentage and is widely used to compare different investments or assess performance.
How ROI Is Calculated
ROI is calculated using the following formula:
ROI (%) = (Net Profit ÷ Investment Cost) × 100
Where:
- Investment cost is the total amount you invested
- Net profit is the return minus the investment cost
This ROI calculator performs the calculation instantly based on the values you enter.
How to Use the ROI Calculator
To calculate ROI:
- Select your currency
- Enter the investment cost
- Enter the total return (revenue or final value)
- View your ROI percentage, net profit, and return multiple
If you enable “Include duration”, the calculator will also estimate:
- Annualised ROI
- Estimated payback period
All results update automatically when values change.
Understanding Your ROI Results
ROI Percentage
The ROI percentage shows how much profit you made relative to your investment.
- A positive ROI means the investment generated a profit
- A negative ROI means the investment resulted in a loss
Net Profit
Net profit is the difference between your total return and your investment cost.
Return Multiple
The return multiple shows how many times your investment was returned (for example, 2.0× means you doubled your investment).
What Is Annualised ROI?
Annualised ROI estimates the average yearly return of an investment over a given period. This is useful when comparing investments with different durations.
This calculator estimates annual ROI, assuming returns are evenly spread. Actual returns may differ based on cash flow timing.
What Is the Payback Period?
The payback period shows how long it takes to get back the money you spent.
A shorter payback period usually means less risk. A longer one may mean more risk.
