Frequently Asked Questions
A shorter payback period is generally better because it means faster return on investment and lower risk. Most businesses prefer a payback period of 3 to 5 years. Capital-intensive industries may accept 7 to 10 years. It depends on your industry and risk tolerance.
Simple payback period does not account for the time value of money — it just divides cost by annual cash flow. Discounted payback period uses present value of future cash flows, giving a more accurate but longer payback timeframe.
Payback period ignores cash flows that occur after the payback date, does not account for the time value of money (in its simple form), and does not measure total profitability. It is best used alongside NPV and IRR for a complete investment analysis.
