What is a good payback period for capital investments?

Most corporations target payback periods between 2 and 4 years. Shorter payback periods minimize risk and free up capital for reinvestment.

How do you calculate payback period for uneven cash flows?

Sum yearly cash flows until cumulative inflows exceed initial outlay. Then add the fraction: (Unrecovered Cost at Start of Year / Cash Inflow During Year).

What is the main limitation of the standard Payback Period method?

Standard payback ignores the time value of money (a dollar today is worth more than a dollar tomorrow) and ignores all cash flows earned after the payback point.

How does Payback Period differ from Net Present Value (NPV)?

Payback measures liquidity and recovery speed, whereas NPV measures total lifetime economic profit added to the firm discounted to present value.

Can a project have a short payback period but a negative NPV?

Yes! If a project pays back in 1 year but cash flows cease immediately thereafter, it may fail to exceed the cost of capital, resulting in a negative NPV.

What is Discounted Payback Period?

Discounted payback applies a discount rate to each cash flow before summing them, addressing the time value of money limitation.
