How do you calculate First Article Inspection cost for a mold?

Add the three cost elements: sample production cost (material, press time, setup), measurement and inspection labor, and documentation/reporting. With $2,500 + $1,800 + $900 the total FAI cost is $5,200.

What should be included in sample production cost?

Resin and colorant for the sample shots, press time to mount the mold and run qualifying cycles, and the setup labor to dial in the process. In the example this is the largest bucket at $2,500.

Why is inspection labor so expensive on a first article?

A full FAI is a 100% dimensional layout against the print — every feature on a CMM or with hand gauges — plus capability studies. That hands-on metrology time runs $1,800 in the example and is often the second-largest cost.

Should FAI cost be quoted to the customer or absorbed in tooling?

Quote it. FAI is a deliverable the customer requires, so it belongs as a visible line item in the mold quotation. Burying $5,200 in overhead directly erodes your tooling margin.

What is the difference between FAI cost and PPAP cost?

FAI is the dimensional and material validation of the first parts; PPAP is the broader automotive submission package that contains the FAI plus control plans, FMEAs, and more. PPAP cost is usually higher because of the added documentation.

How can I reduce mold first article cost?

Reduce sample scrap with a well-developed process before the formal run, batch inspection on a programmed CMM routine, and reuse documentation templates. The documentation bucket ($900 here) is usually the easiest to trim with reusable AS9102 or PPAP forms.

Injection Molding calculator

Mold First Article Cost Calculator

Mold First Article Cost is the total spend required to produce and fully validate the first parts off a new or modified injection mold before the customer signs off on production. Tooling engineers, mold project managers, and quoting estimators use it to recover FAI effort that is otherwise buried in overhead and erodes tooling margin. It matters because PPAP-level inspection of a first article — full dimensional layout, material certs, capability studies — routinely costs thousands per program, and customers expect it line-itemed in the quote rather than absorbed silently.

What this calculator does

Estimate the total cost of a first article inspection (FAI) from sample production cost, measurement labor, and documentation time.
Use this when budgeting for new mold qualifications, quoting PPAP or FAI costs to customers, or planning resources for mold trial activities.
It sums the three real cost buckets of a First Article Inspection — sample press production, dimensional inspection labor, and documentation — into one total FAI charge.

Formula used

Total FAI cost = Production cost + Measurement cost + Documentation cost
Include in mold project budget and customer quotation

Inputs explained

Sample production cost (material + press + setup):
Measurement and inspection labor cost:
Documentation and reporting cost:

How to use the result

Use it when quoting a new mold, after an engineering change that triggers a re-validation, or any time a customer requires a documented PPAP or AS9102 first-article submission.
It is a simple sum of estimated costs, so it is only as good as your line-item estimates; it does not account for re-runs caused by failed dimensions, scrapped samples, or supplier-charge markups.

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 9,635 plastics product manufacturing establishments employing about 677,302 workers (Census County Business Patterns, 2023).
