When calculating payback period, which statement is true?

• A. It is always measured annually.
• B. It ignores initial investment.
• C. It is the time required for cumulative net benefits to equal the initial investment, often measured monthly or quarterly.
• D. It equals the project’s internal rate of return.

Answer: (C)

Payback period measures how long it takes for the project to recover the initial investment from its cash inflows. You add up the project’s cash inflows by period until those cumulative inflows equal the upfront outlay. Because you can track cash flows more precisely than once a year, it’s common to measure the payback in months or quarters to get a more exact date. For example, with a certain upfront cost, you’d reach the initial investment during a specific period and could interpolate to find the exact time within that period. This metric is about recovering the initial outlay, not about comparing to other measures like IRR, and it isn’t restricted to annual calculations. If you’re using a simple (undiscounted) version, it doesn’t account for the time value of money, which is why discounted methods are used when a more accurate picture is needed.
