It considers the cost of the money spent today against the savings that we might see tomorrow.

• A. Net Present Value (NPV)
• B. Payback
• C. EF
• D. SLE

Answer: (B)

The key idea is how long it takes to recover the money you spend today from future savings. The payback period does exactly that: it looks at the initial outlay and asks how many years (or periods) it takes for the inflows to equal that cost. It’s a simple quick-check that focuses on recovery time rather than how money’s value changes over time, which is why it’s the best fit for this description. In contrast, Net Present Value would discount future savings back to today’s value and compare the total to the initial cost to judge overall profitability, not just how fast you break even. The other options relate to different risk measures rather than investment payback.
