Tooling, Fixtures, Dies & Mold Economics calculator

Fixture Payback Calculator

Check when a fixture repays its installed cost. Enter annual savings, incremental upkeep, remaining useful program life and your permitted payback period.

What this calculator does

  • Check whether the fixture investment recovers within your permitted payback and remaining useful program life.

Formula used

  • Annual net savings = annual gross savings − annual incremental upkeep
  • Simple payback = investment ÷ positive annual net savings
  • Remaining net benefit = annual net savings × remaining life − investment
  • Target headroom = maximum allowed payback − simple payback
  • Life headroom = remaining useful program life − simple payback

Inputs explained

  • Fixture Investment: Installed quote including qualification and directly attributable startup costs.
  • Annual Gross Savings: Annual labor, scrap or rework cash savings against the baseline.
  • Annual Incremental Upkeep: Incremental annual support costs on the same comparison basis.
  • Remaining Useful Program Life: Remaining tool service or committed program life, whichever is shorter.
  • Maximum Allowed Payback: Your organization’s permitted recovery period for this investment.

How to use the result

  • Best suited to fixture capital Approval, program life check.
  • Discounting, tax, financing and resale proceeds are excluded. Uneven yearly savings require a separate cash-flow schedule.

Current U.S. benchmarks

  • The producer price index for plastic resins and materials stands at 280.569 (BLS, Aug 2026), up 6.6% from a year earlier. Quotes priced off last quarter's material cost miss this move.
  • The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).

Common questions

  • Why is payback blank? A positive investment needs positive net annual cash savings. Verify the savings and upkeep inputs if recovery cannot be calculated.
  • Should upkeep be the whole maintenance budget? Use only the annual cost attributable to this investment, consistently with the baseline used for gross savings.
  • Does payback include the time value of money? No. This is simple payback using steady annual cash flows. Use a discounted analysis for financing and timing decisions.
  • Why enter remaining life? A short recovery period still fails if the tool or part program ends first. The remaining-life headroom checks that limit.
