  You invest ₹10,000. After a year, you earn ₹12,000.
  Profit = ₹2,000 → ROI = (2,000 ÷ 10,000) × 100 = 20% 

How to Calculate Absolute ROI and ROI Formula

The ROI formula is easy to understand. It simply compares your gain or loss from an investment to the original amount you invested.

ROI = (Net Profit / Cost of Investment) × 100

• Cost of investment is the amount of money you put in.

You invest ₹50,000 in a business. After 6 months, the business earns ₹65,000.
Your net profit = ₹65,000 – ₹50,000 = ₹15,000
Now apply the ROI calculation method:

ROI = (15,000 / 50,000) × 100 = 30%

This means you made a 30% profit on your investment.

ROI vs Other Financial Metrics

Metric	Definition	Difference from ROI
Net Profit Margin	Measures profit as a percentage of revenue	Doesn’t include cost of investment
Internal Rate of Return (IRR)	Shows profitability over time	IRR considers when cash flows happen
Net Present Value (NPV)	Predicts profit in today’s value	Adjusts for inflation and risk
Payback Period	Time needed to recover the investment	Doesn’t measure profit, only recovery time

When to Use ROI vs Other Metrics?

Knowing when to use ROI vs other metrics is crucial for making smart financial decisions. Each metric serves a different purpose depending on the type, duration, and risk level of the investment.

• Use ROI for quick decisions on profitability
  Return on Investment (ROI) is ideal when you need a simple and fast way to measure the profitability of a project or investment. It gives a percentage-based snapshot of what you’ve earned compared to what you spent. This makes it highly useful for short-term decisions or comparing two or more options side by side.
• Use IRR for complex, long-term investmentsInternal Rate of Return (IRR) considers the timing of cash flows and provides a more realistic view of profitability over time. It is especially helpful for large projects or investments with multiple inflows and outflows. When future cash flows are irregular or span over many years, ROI vs IRR shows a clear difference—IRR is the better choice in such cases.
• Use NPV to understand value today
  Net Present Value (NPV) calculates how much profit your investment is expected to generate in today’s terms. It adjusts for inflation and risk, making it suitable for decisions where the value of money over time is a key factor. Comparing ROI vs NPV helps investors see both short-term gains and long-term value.
• Use Payback Period for liquidity-focused decisions
  If your priority is to know how fast you will recover your investment, the payback period is useful. It tells you how long it will take to break even, without focusing on overall profit. This is useful when cash flow and risk reduction are more important than return.

In summary:

• Use ROI for simple, short-term decisions.
• Choose IRR or NPV for long-term, high-value projects.
• Use Payback Period when you need to recover your money quickly.

Conclusion

Return on Investment (ROI) and how to measure ROI effectively are key tools for understanding how profitable an investment is.

The ROI formula is (Net Profit / Investment Cost) × 100
