Payback period calculator

Payback is the crudest capital test and the one owners actually use, because it answers the question that keeps them awake: when does the money come back?

  • Payback ignores everything that happens after break-even — pair it with NPV.

How to use this calculator

  1. 1Enter the investment amount and the annual net cash benefit.
  2. 2Add ongoing annual costs so the benefit is a net figure.
  3. 3Set a discount rate to see the discounted payback.

Simple vs discounted payback

Simple payback divides the investment by annual net cash flow. Discounted payback applies your cost of capital first, which typically pushes the break-even point out by 15-30%.

Neither method values anything after break-even, so a project with a short payback and no tail can rank ahead of a far more valuable long-lived asset. Read payback with NPV, never instead of it.

Setting a payback policy

Many SMEs set a rule: equipment must pay back in under three years, software under 18 months, marketing within a quarter. Rules like these protect cash when capital is scarce.

Where a purchase also removes a bottleneck, add the value of the extra throughput to the cash flow rather than budgeting the saving alone.

Frequently asked questions

Should I use profit or cash flow?

Cash flow. Depreciation is not a cash cost, so profit understates the cash the asset actually returns.

What payback do lenders want?

Comfortably inside the loan term. A five-year loan against an asset with a seven-year payback will usually be declined.

Does payback account for asset life?

No, which is its main weakness. Use NPV or IRR to capture value earned after the payback point.
