What is Return on Investment (ROI)?
Return on Investment (ROI) is a performance metric used to evaluate the profitability or efficiency of an investment. It directly measures the amount of return on a particular investment, relative to the investment's cost.
ROI is expressed as a percentage and is calculated by dividing the net profit (or loss) from an investment by the cost of the investment. The result is multiplied by 100 to get a percentage value.
ROI is popular because of its versatility and simplicity. It can be used to compare the profitability of different investments, evaluate business proposals, or assess the performance of completed projects.
The ROI Formula
The basic formula for calculating ROI is straightforward:
Basic ROI Formula
$$ROI = \frac{Net\,Profit}{Investment\,Cost} \times 100\%$$
This formula gives you the total ROI for your investment, expressed as a percentage.
Formula Parameters
- Net Profit: The gain from the investment minus the cost of the investment (Final Value - Initial Investment)
- Investment Cost: The initial amount invested in the project or asset
Advanced ROI Calculations
Annualized ROI
When investments span different time periods, it's useful to annualize the ROI to make fair comparisons. Annualized ROI normalizes returns to a yearly rate:
Annualized ROI Formula
$$Annualized\,ROI = \left(1 + \frac{Net\,Profit}{Investment\,Cost}\right)^{\frac{1}{n}} - 1$$
Where 'n' is the number of years the investment is held. This accounts for the compounding effect over time.
ROI in Different Contexts
ROI calculations vary slightly depending on the investment type:
- Stock Investment ROI: For stocks, ROI includes both capital gains and dividends received.
- Real Estate ROI: For property, ROI considers rental income, property appreciation, and expenses like maintenance, taxes, and insurance.
- Business Investment ROI: For business projects, ROI evaluates profits generated against resources allocated to the project.
