How do you calculate fixture payback period?

Subtract annual support cost from annual savings to get net savings, then divide fixture cost by net savings. A $25,000 fixture saving $18,000/yr with $2,500/yr support has $15,500 net savings and a 1.61-year payback.

What is a good fixture payback period?

On a shop floor, most fixture projects target under 12-18 months. The 1.61-year (about 19-month) default is acceptable for a durable fixture but would be reviewed hard if the program life is short.

Why subtract support cost from savings?

A fixture isn't free to keep running — recalibration, wear parts, and cleaning cost money. Netting $2,500/yr support against $18,000 savings gives the real $15,500/yr the fixture returns.

What does five-year net value mean here?

It's net annual savings times five, minus the fixture cost: $15,500 x 5 - $25,000 = $52,500. It shows the cumulative return if the fixture serves the full five-year horizon.

Payback period vs ROI — which should I use?

Payback answers how fast you get your money back; five-year net value answers how much total value you capture. Use payback to screen risk and net value to compare project size.

How can I shorten fixture payback?

Raise annual savings (more parts through the fixture, bigger scrap reduction), cut support cost, or lower build cost through simpler design. Each dollar of net savings above $15,500 pulls the 1.61-year payback down.

Tooling, Fixtures, Dies & Mold Economics calculator

Fixture ROI Calculator

Fixture ROI expresses how long a workholding, welding, or assembly fixture takes to pay for itself out of the labor and scrap savings it generates, net of its upkeep. Manufacturing engineers and continuous-improvement teams use it to justify capital requests and to rank competing fixture projects. A fixture that cuts setup time and scrap but needs regular recalibration only earns its keep once net savings exceed the build cost. Payback period and five-year net value together tell you whether to build, defer, or redesign.

What this calculator does

Estimate fixture roi for tooling, fixtures, dies and mold economics using production-ready inputs so teams can screen a capital project before a detailed business case.
Use it when fixture roi in tooling, fixtures, dies and mold economics is being compared against another tooling, fixtures, dies and mold economics project for the same budget.
It computes the payback period and five-year net value of a fixture from its build cost, gross annual savings, and annual support cost.

Formula used

Net annual fixture roi savings = annual fixture roi savings - annual fixture roi support cost
Fixture roi payback period = fixture roi investment ÷ net annual savings

Inputs explained

Fixture design and build cost:
Annual labor and scrap savings from the fixture:
Annual fixture upkeep cost:

How to use the result

Use it when justifying a fixture capital request, comparing build-vs-buy or manual-vs-fixtured options, or ranking a backlog of fixture projects.
It uses simple undiscounted payback and assumes savings and support costs are flat every year; it ignores the time value of money and volume changes that shift savings.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 319.371 (BLS, May 2026), up 19.5% 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).
