What this ROI calculator does
Use this page for a quick simple ROI calculation when you know the amount invested and the value returned from the investment or project. The calculator shows net return and ROI as a percentage of the original cost.
ROI formula
Net return is the difference between the ending value or return and the original investment cost.
ROI expresses the gain or loss as a percentage of the original investment cost.
For example, a $100,000 investment that returns $130,000 has a $30,000 net return and a simple ROI of 30%.
When simple ROI is not enough
- Different holding periods should not be compared without annualizing or using a time-based method.
- Fees, taxes, and inflation can reduce the real return.
- Projects with irregular cash flows may need NPV, IRR, or a payback analysis.
- Higher ROI can also mean higher risk or incomplete cost assumptions.
