Which metrics are commonly used to evaluate capital budgeting projects?

• A. NPV
• B. IRR
• C. Payback
• D. All of the above

Answer: (D)

Evaluating capital budgeting projects often relies on multiple metrics because each one highlights a different aspect of a project’s potential.

Net present value looks at value creation by discounting all future cash flows back to today and subtracting the initial outlay. A positive NPV signals that the project adds value at the chosen discount rate, making it a solid overall profitability measure that accounts for both timing and scale of cash flows.

Internal rate of return expresses the project’s profitability as a percentage return, finding the discount rate that makes NPV zero. IRR is intuitive for comparing projects of different sizes and cash-flow patterns because it translates value into a rate of return you can compare to the cost of capital or hurdle rates.

Payback focuses on liquidity and risk by showing how quickly the initial investment is recovered. It’s simple and easy to understand, which makes it useful for shorter-term planning, but it doesn’t capture all cash flows after payback and ignores the time value beyond the cutoff.

Because each metric sheds light on different dimensions—overall value, percentage return, and liquidity—both practitioners and textbooks commonly use them together. That’s why the best answer is that all of the above are commonly used.
