The method, explained

Simple payback period = initial outlay ÷ constant annual net cash inflow.

A WORKED EXAMPLE

An initial outlay of 10,000 with 2,500 in annual net cash inflow has a simple payback of 4 years.

What to keep in mind

Assumes even, positive annual inflows. It ignores discounting, taxes unless reflected in inputs, and cash flows after payback.

Common questions

Does this account for the time value of money?

No. Discounted payback and net present value require a discount rate and cash-flow schedule.

Can I use accounting profit as cash flow?

Not automatically. Depreciation, working-capital changes and other adjustments can make cash flow differ from profit.
