How do you calculate quote margin on an appliance control board?

Subtract the estimated total board cost from the quoted selling price to get gross margin per board, then divide by the reference price and multiply by 100. At $18.75 quoted and $14.25 cost, that is $4.50 per board, or 24%.

What is a good margin on a PCBA control board?

EMS control board quotes commonly target 15–30% gross depending on volume and complexity; high-volume commodity boards run lower, complex or low-volume boards higher. The 24% in the example is a healthy mid-volume figure.

Why is board margin so sensitive to component cost?

On a $14.25 board, a single MCU or power device that moves $0.50 swings margin by nearly 3 points, so a quote that looks safe at 24% can drop below target on one component price increase across a 200k-unit run.

Margin vs markup on control boards — which should I quote against?

Quote against margin, which is profit over price. The same $4.50 spread is a 31.6% markup on $14.25 cost but only 24% margin on the $18.75 price, so confirm your floor uses the right basis.

Should NRE and test development be in the board cost?

Not in the per-board cost — quote those separately as NRE and tooling. But remember the 24% per-board margin does not fund them, so a program with heavy test development needs either NRE recovery or a higher per-board margin.

How does scrap and rework affect quoted board margin?

Yield loss eats directly into per-board margin, so if you expect 2–3% scrap on a new control board, build that into the estimated total cost or the realized margin will fall short of the quoted 24%.

Appliance Control Board Quote Margin Calculator

Quoted control board margin is the percentage of a control board's selling price that remains as gross profit after the estimated total cost to build it. EMS and OEM sales teams use it when quoting appliance control boards and PCBA programs to appliance makers, where annual volumes run into the hundreds of thousands and pennies per board decide program profitability. It matters because component prices, especially MCUs, power devices and connectors, swing with the market while the customer expects a firm per-board price, so margin discipline at quote protects the program across its full production run. Most EMS quoting desks gate per-board pricing against a floor margin before release.

What this calculator does

Calculate quote margin for appliance electronic assemblies from quoted selling price, estimated board cost, and margin reference amount.
an estimator or contract manufacturer needs to check margin on an appliance control board quote
It computes the gross margin per board in dollars and as a percentage between the quoted selling price and the estimated total board cost.

Formula used

Gross margin per board = quoted control board selling price - estimated total board cost
Quoted control board margin = gross margin per board ÷ margin reference price × 100

Inputs explained

Quoted control board selling price: undefined
Estimated total board cost: undefined
Margin reference price: undefined

How to use the result

Use it when quoting a control board or PCBA program to an appliance OEM, before committing a firm per-board price.
It is a per-board gross margin and excludes NRE, tooling, test development, scrap and end-of-life component risk, so the realized program margin is usually lower.

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).
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
The U.S. has 11,261 computer and electronic products establishments employing about 815,443 workers (Census County Business Patterns, 2023).
