Payback Period
The payback period is the length of time required for an investment to recover its initial cost from the net cash inflows it generates.
Explanation
Payback period answers a straightforward question: how long until we get our money back? It is calculated by dividing the initial investment by the annual net cash inflow (for uniform cash flows) or by adding cash flows year by year until the cumulative total equals the investment.
Shorter payback periods are preferred because they reduce the window of risk and free up capital sooner. Organizations often set a maximum acceptable payback period as a screening criterion. Projects that exceed this threshold are rejected regardless of other merits.
The limitation of payback period is that it ignores cash flows that occur after the payback point and does not account for the time value of money. A project that pays back in 2 years but generates massive returns in years 3-5 would look identical to one that pays back in 2 years with no further returns. For this reason, payback period is best used as a supplementary metric alongside NPV or IRR.
Key Points
- •Measures how long it takes to recover the initial investment
- •Shorter payback period is preferred
- •Does not consider cash flows after the payback point
- •Does not account for the time value of money
Exam Tip
Shorter payback period is better. Remember its key limitation: it ignores all cash flows after the investment is recovered.

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.
