What Is An ROI Calculator?
The ROI Calculator is a financial tool used to evaluate the profitability or efficiency of an investment. It calculates ROI by comparing the gain or loss from an investment relative to its cost.
Return On Investment Formula
The basic ROI formula used by an ROI Calculator is:
ROI = (Net Profit / Investment Cost) × 100For example, if you invest Rs 1,000 in a project and earn Rs 1,300, your net profit is Rs 300. The ROI would be 30%. This simple calculation can offer valuable insights into whether an investment is worthwhile.

Limitations of the ROI Calculator
- Ignores Time Value of Money: Basic ROI does not account for how long it takes to earn returns.
- Does Not Measure Risk: A high ROI investment may also carry higher risk.
- Can Oversimplify Complex Projects: Intangible benefits like brand awareness or customer satisfaction may not be fully reflected.
For these reasons, ROI should often be used alongside other financial metrics such as Net Present Value (NPV) or Internal Rate of Return (IRR).
Difference Between ROI, IRR, And NPV
| Metric | Full Form | Definition | Key Focus | Best Used For | Limitations |
|---|---|---|---|---|---|
| ROI | Return on Investment | Measures the profitability of an investment relative to its cost | Profitability percentage | Quick comparison of investments | Ignores time value of money and risk |
| IRR | Internal Rate of Return | The discount rate at which the net present value of cash flows equals zero | Annualized growth rate | Evaluating long-term projects | Can be misleading for non-conventional cash flows |
| NPV | Net Present Value | The difference between present value of cash inflows and outflows | Total value added | Assessing absolute profitability | Depends heavily on discount rate assumptions |
