How do you calculate fixture build cost?

Multiply build labor hours by your toolroom shop rate, then by the billable utilization percentage, and add the flat material and hardware cost. With 60 hours at $95/hr, 90% utilization and $1,500 in material, that is 60 x 95 x 0.90 + 1,500 = $6,630.

Why apply a billable utilization percentage?

Not every clocked hour in the toolroom is recoverable — some goes to setup, waiting, or non-billable touch-up. Applying 90% utilization means you recover $5,130 of labor instead of the full $5,700, which reflects what you can realistically bill or absorb into the part price.

What is a good cost per fixture build hour?

In the example the fully-loaded cost per build hour is $110.50, because the $1,500 material adder is spread across 60 hours on top of the ~$85.50 recovered labor rate. Watch this number when material-heavy fixtures push effective hourly cost well above your posted shop rate.

Should design engineering be included in fixture build cost?

This calculator covers build labor and material only. Design, CAD modeling and first-article proving are typically tracked as separate engineering hours; roll them in before amortizing the fixture over annual part volume.

How do I amortize a fixture into part price?

Divide the total fixture cost — $6,630 here — by the expected number of parts the fixture will hold over its life. A fixture running 50,000 parts adds about $0.13 per part; the same fixture on a 500-part job adds $13.26 per part.

Build in-house or buy the fixture outside?

Compute your in-house total ($6,630) and compare against the outside quote plus your own receiving, inspection and integration time. In-house wins when toolroom capacity is idle; outsourcing wins when your billable utilization is already maxed on revenue work.

Fixture Build Cost Calculator

Fixture build cost is the fully-loaded price of designing and fabricating a workholding or check fixture in your toolroom, combining recovered labor and a flat material-and-hardware charge. Manufacturing engineers, tool designers and estimators use it to quote fixture jobs, decide build-versus-buy, and set the tooling amortization line on a part quote. Getting it right matters because an under-costed fixture quietly erodes margin on every part it holds, while an over-costed one loses the job. This calculator separates the variable (recovered labor) piece from the fixed material adder so you can see exactly where the money goes.

What this calculator does

Estimate the cost to design and build a workholding fixture from labor hours, shop rate and material.
A toolroom quotes a custom locating fixture for a new part before releasing the build order.
It computes the total fully-loaded build cost of a fixture as recovered labor (hours x rate x billable utilization) plus a flat material and hardware charge, and the resulting cost per build hour.

Formula used

Total fixture cost = build hours x shop rate x billable utilization% + material flat
Cost per build hour = total cost / build labor hours

Inputs explained

Fixture build labor hours:
Toolroom shop rate:
Billable labor utilization:
Material & hardware flat cost:

How to use the result

Use it when quoting a new fixture, setting the tooling amortization on a part quote, or comparing an in-house build against an outside toolmaker's price.
The utilization factor recovers only booked-and-billable time; it does not capture design engineering, first-article proving, or rework loops, so add those separately for a true program cost.

Current U.S. benchmarks

As of May 2026, U.S. manufacturing runs at 75.6% of capacity (Federal Reserve via FRED), up 0.2 points from a year earlier. Enter your own plant's utilization; the national figure is a reference point for how loaded the industry is.
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).
