Fixture, Gauge & Workholding Management calculator

Fixture ROI Calculator

Estimate payback for a new or upgraded fixture by comparing the fixture investment with annual setup, scrap, inspection, and uptime savings. Use it when a tooling engineer or production manager needs to justify a machining fixture, checking fixture, pallet, tombstone, or dedicated nest before capital approval.

What this calculator does

  • Estimate payback for a new or upgraded fixture by comparing the fixture investment with annual setup, scrap, inspection, and uptime savings.
  • Use it when a tooling engineer or production manager needs to justify a machining fixture, checking fixture, pallet, tombstone, or dedicated nest before capital approval.
  • Screens the business case for a fixture, jig, nest, pallet, tombstone, or checking fixture investment.

Formula used

  • Net annual fixture ROI savings = annual fixture savings - annual fixture support cost
  • Fixture ROI payback period = fixture project investment รท net annual savings

Inputs explained

  • Fixture project investment: Enter the complete project investment: fixture build, pallets, clamps, tombstones, design, programming, tryout, training, installation, and launch support.
  • Annual fixture savings: Use documented annual savings from setup reduction, scrap reduction, less inspection time, higher uptime, added spindle utilization, or avoided outsourcing.
  • Annual fixture support cost: Include annual maintenance, replacement clamps, calibration, spare locators, software, storage, and toolroom support required to keep the system usable.

How to use the result

  • Use it before a detailed capital request, supplier quote approval, or make-versus-buy review for dedicated workholding or inspection tooling.
  • Payback depends on stable volume, setup frequency, scrap history, operator adherence, machine availability, and tool maintenance. Treat it as a screening estimate before a full capital request.

Common questions

  • What information do I need before using the Fixture ROI? Use the full fixture investment, annual savings from the same part family or production cell, and yearly support costs such as maintenance, replacement locators, clamps, calibration, and storage.
  • What does the result mean? It estimates the number of years required for annual net savings to recover the fixture or workholding investment.
  • When is the result only an estimate? It is an estimate when part mix, datum scheme, tolerance stack, clamp layout, operator method, inspection plan, gauge condition, calibration status, maintenance history, machine uptime, or production volume differs from the assumptions entered.
  • What decision can I make from the result? Use the payback to decide whether to proceed with fixture design, request quotes, add the project to a capital list, or compare it with other setup-reduction ideas.
