A worked example
A $10,000 outlay returning $3,000 a year pays back in exactly 3.33 years — three full years of $3,000 plus a third of a year to cover the remaining $1,000.
Frequently asked questions
What does payback period leave out that other measures capture?
It ignores any cash flow after the breakeven point entirely, and doesn't discount future cash flows to account for the time value of money. It's a quick risk/liquidity check, not a full profitability measure — pair it with IRR or NPV for the fuller picture.
Why might a shorter payback period still not mean a better investment?
A project with a fast payback but low cash flows afterward could earn less overall than one with a slower payback but much larger flows later. Payback period favors speed of return, not total return.
