How do you calculate electronics manufacturing cost?

Multiply build quantity by the variable cost per assembly, then add assembly labor/setup and manufacturing overhead. For 1,500 assemblies at $18.50 each plus $4,200 labor/setup and $3,100 overhead, total cost is $35,050, or about $23.37 per assembly.

What is included in variable cost per assembly?

It is the marginal cost to build one more board: typically the BOM component cost plus per-board consumables and direct machine time. It excludes the one-time setup and the overhead that are entered separately, which is why the $18.50 here is lower than the $23.37 loaded figure.

Why is cost per assembly higher than the variable cost?

Because fixed labor, setup, and overhead are amortized across the run. Here $7,300 of fixed cost spread over 1,500 boards adds about $4.87 per board, lifting the $18.50 variable cost to $23.37 loaded.

How does build quantity affect cost per assembly?

Larger quantities dilute the $7,300 fixed block, so cost per assembly falls toward the $18.50 variable floor. Doubling the run to 3,000 would cut the fixed adder roughly in half to about $2.43, giving a loaded cost near $20.93.

What is a good manufacturing cost per assembly?

There is no universal number - it depends entirely on board complexity and BOM. The useful test is the ratio of loaded to variable cost: at $23.37 vs $18.50 the fixed burden is about 26%, which is reasonable for a 1,500-unit run but would be high for high-volume production.

Electronics manufacturing cost vs landed cost - what's the difference?

This tool covers the factory-gate manufacturing cost. Landed cost adds freight, duties, packaging, and inbound logistics on top, so your shipped cost will exceed the $23.37 per-assembly figure shown here.

Electronics Manufacturing calculator

Electronics Manufacturing Cost Calculator

Electronics manufacturing cost is the total loaded cost to build a PCBA run, combining the per-board variable cost with the fixed labor, setup, and overhead that get spread across the quantity. EMS account managers, manufacturing engineers, and hardware program managers use it to quote builds, validate supplier pricing, and find the break point where a larger run drops the per-assembly cost into target. On SMT lines the NRE-style setup and stencil/program burden can dominate small runs, so seeing the split between variable and fixed cost is what turns a quote into a decision. This calculator gives you both the total and the cost per assembly from one set of inputs.

What this calculator does

Estimate total electronics manufacturing cost from build quantity, variable assembly cost, labor/setup cost, and overhead.
an estimator or operations manager needs a fast cost rollup for an electronics build
It computes total manufacturing cost as build quantity times variable cost per assembly plus assembly labor/setup and manufacturing overhead, then divides by quantity for cost per assembly.

Formula used

Total electronics manufacturing cost = build quantity × variable manufacturing cost + labor/setup + overhead
Manufacturing cost per assembly = total electronics manufacturing cost ÷ build quantity

Inputs explained

Build quantity:
Variable manufacturing cost:
Assembly labor and setup cost:
Manufacturing overhead and program burden:

How to use the result

Use it when quoting a PCBA build, evaluating an EMS quote, or sizing the volume needed to hit a target board cost.
It treats variable cost per assembly as flat and bundles all fixed cost into two buckets, so it will not capture component price breaks, scrap, rework, or yield-driven cost growth at the line.

Current U.S. benchmarks

The producer price index for copper and brass mill shapes stands at 559.593 (BLS, May 2026), up 76.8% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,484 per tonne (IMF via FRED, May 2026).
The U.S. has 11,261 computer and electronic products establishments employing about 815,443 workers (Census County Business Patterns, 2023).
