Frequently asked questions
What is the difference between payback period and discounted payback period?
The payback period ignores the time value of money, while the discounted payback period discounts future cash flows to present value, giving a more accurate measure of when the investment is recovered in today's dollars.
Is a shorter payback period always better?
Generally, a shorter payback period is preferred because it reduces risk and frees up capital sooner. However, it does not consider profitability after the payback period, so a longer payback investment might be more profitable overall.
Can this calculator handle irregular cash flows?
No, this calculator assumes constant annual cash flows. For irregular cash flows, a more detailed cash flow analysis is needed.
