Payback period measures:

The payback period is a capital budgeting technique used to evaluate potential investment projects. Its primary focus is on how quickly an initial investment can be recouped from the project's cash flows. Therefore, Time to recover investment is the correct answer. It calculates the number of years required for the cumulative cash inflows from a project to equal the initial cash outlay.

• While a shorter payback period might be preferred, it does not directly measure overall profitability, as it ignores cash flows occurring after the payback point.
• It is not a direct measure of a company's general liquidity, which assesses overall short-term solvency.
• It also doesn't provide a comprehensive assessment of a project's overall risk, although a quicker payback might be seen as less risky in some contexts.
