What this calculator does

Payback period shows how long it takes for a project, tool, machine or campaign to recover its upfront cost from net monthly benefit.

Formula used

Net monthly benefit equals monthly benefit minus ongoing monthly cost. Payback period equals upfront cost divided by net monthly benefit.

How to read the result

A shorter payback period can reduce risk, but it does not prove the best investment. Compare payback with useful life, cash flow, risk and total return.

Assumptions

  • Assumes the same net benefit every month.
  • Does not discount future cash flows.
  • Does not include financing costs, tax or residual value.

Frequently asked questions

Is payback period the same as ROI?
