Return on Investment (ROI)
Return on investment (ROI) is a financial metric that measures the percentage gain or loss generated by an investment relative to its cost, calculated as (Net Profit / Cost of Investment) x 100.
Explanation
ROI is one of the simplest and most widely used financial metrics for evaluating projects. It tells stakeholders how much return they receive for each dollar invested. For example, an ROI of 150% means the project returns $1.50 for every $1.00 invested.
ROI is popular because it is easy to calculate and understand. However, it has limitations: the basic formula does not account for the time value of money, the duration of the investment, or the risk profile of the project. Two projects could have the same ROI, but one delivers returns in one year while the other takes five. For this reason, ROI is often used alongside time-adjusted metrics like NPV and IRR.
On the exam, higher ROI is better, and you should recognize ROI as a benefit measurement method used in project selection. Questions may compare ROI across projects or ask about its limitations compared to NPV.
Key Points
- •Calculated as (Net Profit / Cost of Investment) x 100
- •Higher ROI percentage is preferred
- •Simple but does not account for time value of money
- •Often used alongside NPV and IRR for more complete analysis
Exam Tip
Higher ROI is better. But remember that ROI alone does not account for the time value of money—NPV is the more comprehensive measure.

Net Present Value (NPV)
Net present value (NPV) is the difference between the present value of cash inflows and the present value of cash outflows over a period of time, used to assess the profitability of a project or investment.
Internal Rate of Return (IRR)
The internal rate of return (IRR) is the discount rate at which the net present value of all cash flows from a project equals zero, representing the project's expected annualized rate of return.
Benefit-Cost Ratio (BCR)
The benefit-cost ratio (BCR) is a financial metric that compares the present value of benefits to the present value of costs, expressed as a ratio, to determine whether a project's benefits outweigh its costs.
Project Selection Methods
Project selection methods are the techniques organizations use to evaluate and choose which projects to pursue, including mathematical models (NPV, IRR, BCR) and comparative approaches (scoring models, peer review).
