What is Return on Investment (ROI)?

ROI is a financial metric used to measure the profitability of an investment. It is expressed as a percentage and calculated by dividing net profit by the cost of the investment.

How is ROI calculated?

ROI = (Net Profit / Cost of Investment) × 100 Net Profit = Final Value of Investment - Initial Cost.

Why is ROI important?

ROI helps investors compare the efficiency and profitability of different investments, making it easier to decide where to put money.

Does ROI consider the time period of investment?

Basic ROI does not consider time. For time-adjusted performance, metrics like annualized ROI or CAGR (Compound Annual Growth Rate) are used.

Yes, a negative ROI indicates a loss on the investment.

Is ROI the only metric to evaluate investments?

No, ROI is simple but does not capture risk, time value of money, or cash flow timing. Other metrics like IRR, NPV, and payback period provide deeper insights.

Return on Investment (ROI) - Complete Guide

What is ROI?

Return on Investment (ROI) is a popular financial metric used to evaluate the profitability of an investment. It shows the percentage return gained relative to the cost of the investment. ROI is widely used across personal finance, business, and marketing to determine the efficiency of spending and investment strategies.

How does ROI work?

Return on Investment (ROI) is a basic profitability metric that helps evaluate the performance of an investment. It calculates how much return you earned compared to what you spent. It does not consider compounding, time, or risk — it’s purely a profit-to-cost ratio expressed as a percentage.

ROI Formula:

ROI = ((Gain from Investment - Cost of Investment) / Cost of Investment) × 100

Where:

Gain from Investment: Total amount received from the investment
Cost of Investment: The amount initially spent

Example:

If you invest ₹10,000 in a stock and later sell it for ₹12,000 after 5 years, the ROI would be:

Net Gain = ₹12,000 - ₹10,000 = ₹2,000
ROI = (₹2,000 / ₹10,000) × 100 = 20%
CAGR = [(12,000 / 10,000)^1/5 - 1] × 100 ≈ 3.71%

Important Note: CAGR helps understand annual growth rate over time, making it useful for comparing investments with different durations. ROI is great for quick comparisons, but for long-term investments, consider using CAGR (Compound Annual Growth Rate) for a time-adjusted return.

Who Should Use ROI?

Individual investors assessing stock or real estate returns
Businesses measuring project or marketing performance
Startups justifying product development costs
Anyone comparing multiple investment options

Types & Variations of ROI

Annualized ROI: Adjusts ROI for time, helpful for comparing long vs short-term investments.
Marketing ROI (MROI): Used to track revenue generated from marketing spend.
Social ROI (SROI): Evaluates social/environmental returns along with monetary ones.

Limitations of ROI

Does not account for time value of money
Ignores risk, external market factors, or inflation
Can be manipulated based on how gains or costs are reported
Not always reliable for comparing long-term investments

Best Practices

Compare ROI with investment duration
Use with other metrics like IRR, Payback Period, and NPV
Adjust for inflation or opportunity cost if needed
Make sure to include all relevant costs and gains

Conclusion

ROI is a straightforward yet powerful tool for analyzing the efficiency of any investment. It helps investors and businesses make informed decisions. However, it should be used in conjunction with other financial metrics to get a complete picture of the investment's potential.
