Investment screening

Payback Period Calculator

Calculate how long it takes annual cash flow to recover an initial investment.

Limitation

Simple payback ignores time value of money, cash flows after payback, risk and financing costs. Use it as a screening metric, not a full investment decision.

Example

An initial investment of 10,000 with annual cash flow of 2,500 has a simple payback period of 4 years.

How to use the result

Use payback to compare how quickly alternatives recover their upfront cost. Then check return, risk and cash flow timing with more complete metrics.

Common mistakes

Do not treat the fastest payback as automatically best. A project may pay back quickly but have lower lifetime value than a slower, more profitable alternative.
