What Is Return on Investment (ROI)?
Return on Investment (ROI) is a performance metric used to evaluate the efficiency or profitability of an investment. It compares the gain or loss from an investment relative to its cost, expressed as a percentage.
ROI is one of the most widely used financial metrics because it is simple, versatile, and works for evaluating stocks, real estate, business ventures, and even marketing campaigns.
The ROI Formula
Where Net Profit = Final Value − Initial Investment
Interpreting Your ROI
Positive ROI
The investment generated more value than it cost — a profitable outcome.
Zero ROI
The investment returned exactly what was put in — break-even with no profit or loss.
Negative ROI
The investment lost value — you recovered less than the original cost.
Limitations of ROI
While ROI is a powerful tool, it has limitations: it does not account for the time value of money or the duration of the investment. For comparing investments of different lengths, consider using the annualized ROI or metrics like NPV (Net Present Value) or IRR (Internal Rate of Return).
Pro Tip: Compare ROI across different investments over the same time period to make meaningful apples-to-apples comparisons.
Frequently Asked Questions
A 'good' ROI depends on the asset class and your risk tolerance. For example, 7-10% is often considered good for the stock market, while a business venture might require 20% or more to justify the risk.
Profit is an absolute dollar amount (e.g., $500), while ROI is a relative percentage (e.g., 50%). Profit tells you how much you made, but ROI tells you how efficiently you used your capital to make that money.
No. A 50% ROI over 1 year is much better than a 50% ROI over 10 years. To account for time, you should calculate the 'Annualized ROI' which shows the geometric mean return per year.
You should include all costs associated with the investment, including the purchase price, taxes, commissions, maintenance costs, and any other fees incurred to acquire or hold the asset.
