Name one major limitation of the payback period method.

• A. It ignores inflation entirely in every case.
• B. It is the most practical method for evaluating long-term profitability.
• C. It accounts for risk through discounting.
• D. It ignores the time value of money and cash flows occurring after the payback period.

Answer: (D)

The main concept being tested is the limitation of the payback period method: it ignores the time value of money and cash flows after the payback point. Since a dollar today is worth more than a dollar tomorrow, not discounting future cash inflows means they’re treated as equally valuable regardless of when they occur. This distorts the true profitability of a project because later cash receipts can be worth much less in present-value terms.

Additionally, by stopping the assessment at the point the initial investment is recovered, the method ignores all cash flows that come after that moment. That means it doesn’t capture the total return of the project, its overall risk, or the opportunity cost of investing capital elsewhere. As a result, a project with a quick payback but weak long-term gains might look attractive, while one with larger late cash flows could be overlooked.
