How do you calculate contract manufacturing gross margin?

Subtract estimated total job cost from the quoted selling price to get margin dollars, then divide by the quoted price and multiply by 100. With a $48,500 quote and $35,600 cost, that is $12,900 ÷ $48,500 = 26.6%.

What is a good gross margin for a contract manufacturer or job shop?

Many machine and fab shops target 25-35% gross margin on quoted jobs to cover SG&A and leave operating profit. The 26.6% in our example sits at the low end of healthy — workable, but with little room for overruns.

Is gross margin the same as markup?

No. Markup is margin dollars over cost; margin is margin dollars over price. A 26.6% margin on a $48,500 quote equals a 36.2% markup on the $35,600 cost — quoting one when you mean the other underprices jobs.

Why is my realized margin lower than my quoted margin?

Quoted margin uses estimated cost. Scrap, rework, setup overruns, expedite freight, and underestimated cycle times erode it. Build a buffer or track quoted-versus-actual to size the gap.

Should I price on margin or on shop rate?

Both. Shop rate builds the cost; margin sets the price above that cost. Margin is the check that the marked-up quote actually leaves enough after a realistic estimate.

Contract Manufacturing, Job Shop Quoting & Make-to-Order calculator

Contract Manufacturing Margin Calculator

Contract manufacturing gross margin is the share of a quoted job price left after subtracting the estimated cost to build it. Estimators, sales engineers, and shop owners use it to decide whether an RFQ response is worth winning and whether it covers the overhead the headline number hides. On a make-to-order floor, a job can look busy and still bleed cash if the margin is thin, so this figure gates the go/no-go on every quote. It is the single number that tells you if a build pays for itself before you commit machine time.

What this calculator does

Calculate gross margin for a quoted contract manufacturing job or customer program.
checking whether a customer quote meets the shop margin target before release
It computes gross margin dollars (quoted price minus estimated job cost) and expresses that as a percentage of the quoted price.

Formula used

quoted gross margin dollars = quoted selling price for the job - estimated total job cost
contract manufacturing gross margin = quoted gross margin dollars ÷ quoted selling price margin basis × 100

Inputs explained

quoted selling price for the job: Use the net price expected on the customer quote after discounts, freight terms, commissions, and customer-specific allowances.
estimated total job cost: Include material, setup, run labor, machine time, outside services, tooling, inspection, packaging, overhead, and normal scrap allowance.
quoted selling price margin basis: Use the same net quote price or finance-approved revenue basis used for gross margin reporting.

How to use the result

Use it while pricing an RFQ, reviewing a quote before it goes out, or auditing whether won jobs are hitting target margin.
It is a gross margin on estimated cost only — it ignores SG&A, rework, scrap drift, and cost overruns, so realized margin is usually lower than quoted.

The U.S. prime lending rate is 6.75% (Federal Reserve via FRED, 2026-07-02). Payback and financing math should start from today's rate, not a remembered one.
