What is ROI?
Return on Investment, or ROI, is a financial metric used to measure the profitability of an investment by comparing the profit earned with the amount invested. Its appeal lies in its simplicity: whether you are buying an established business, opening a franchise outlet or funding a new venture, ROI condenses the outcome into a single percentage that is easy to understand and compare.
It is one of the most widely used indicators among investors and business owners for evaluating opportunities and comparing the viability of different projects, because it answers a basic question: how much did I earn for every riyal I put in?
The formula and how it works
ROI is calculated as follows:
ROI = (Net Profit ÷ Investment Cost) × 100
- Net profit: the total gain from the investment after deducting all related costs, such as fees, operating expenses and any applicable taxes.
- Investment cost: the full amount spent to make the investment, including the purchase price, brokerage or advisory fees, fit-out and other upfront costs.
- Multiplying by 100: converts the result into an easy-to-read percentage.
Example: calculating ROI step by step
Example: you invest QAR 100,000 and generate a net profit of QAR 20,000.
ROI = (20,000 ÷ 100,000) × 100 = 20%
This means your investment generated a 20% return: every riyal invested came back along with QAR 0.20 of net profit.
Now suppose that return was earned over two years rather than one. The annualised (compound) return is lower and is calculated as: Annualised return = (1 + total ROI)^(1 ÷ number of years) − 1, which works out to roughly 9.5% a year. This is why an ROI figure always needs a time frame next to it.
Why ROI matters and when it is used
- Comparing opportunities: it puts investments of different sizes and types on a common footing.
- Buy and sell decisions: it helps a buyer judge whether a business's asking price is justified by its expected profits.
- Assessing franchise opportunities: it helps estimate the return on franchise fees and fit-out costs, and how long recovery might take.
- Tracking performance: it lets management measure whether an expansion, campaign or initiative paid off.
Common mistakes and limitations
- Ignoring time: a 20% return in one year is very different from 20% over five years.
- Leaving out costs: omitting brokerage, renewal or financing costs inflates the result.
- Confusing revenue with profit: the formula uses net profit, not total sales.
- Overlooking risk: two investments with the same ROI are not equal if one is far riskier.
- Relying on optimistic forecasts: an expected ROI is not a guaranteed one, so test it under several scenarios.
For a fuller picture, use ROI alongside other measures such as payback period, net present value (NPV) and internal rate of return (IRR).
