How do you calculate quote margin?

Subtract job cost from selling price, then divide by the reference amount and multiply by 100. With a $24,500 price, $18,400 cost, and $24,500 reference: ($24,500 - $18,400) / $24,500 x 100 = 24.9%.

What is a good quote margin for elastomer jobs?

It varies by shop and competition, but molded seal and gasket work commonly targets 25–40% gross margin. Our 24.9% example sits at the low end — acceptable for a strategic account but thin once rework risk is considered.

Is this margin or markup?

This is margin — profit as a percent of price — because the reference amount is the selling price. Markup divides profit by cost instead. The same $6,100 profit is a 24.9% margin but a 33.2% markup on the $18,400 cost.

What should I use as the reference amount?

Use the selling price for true gross margin, which is the standard for quoting. You'd only change it to cost if you specifically want markup, or to a different base for a custom contribution analysis.

What are the quote margin dollars?

They are the raw profit: price minus cost. In our example that's $24,500 - $18,400 = $6,100, the dollars left to cover unallocated overhead and profit before the percentage is calculated.

Why is my actual margin lower than the quoted margin?

Usually because the required job cost was understated — missing setup labor, optimistic tooling amortization, or no allowance for rework. Feed a fully loaded cost so the 24.9% you quote is the margin you actually keep.

Quote Margin Calculator

Quote margin tells you what percentage of a gasket, seal, or O-ring job's price is profit after the fully loaded job cost — material, labor, tooling amortization, and overhead. Estimators and sales engineers in elastomer manufacturing use it as the final go/no-go check before sending an RFQ response. Because elastomer jobs carry hidden costs like setup, deflashing, and rework risk, a margin that looks healthy on material alone can evaporate, making this the number that decides whether a quote is worth winning.

What this calculator does

Calculate quote margin for gasket, seal, O-ring, and elastomer component jobs by comparing quoted selling price with required cost.
Use it when estimating molded seals, die-cut gaskets, extrusion profiles, adhesive-backed parts, service kits, or custom elastomer components and deciding whether the quote can absorb material, labor, tooling, scrap, inspection, and packaging cost.
It computes the margin dollars (price minus cost) and expresses them as a percentage of a chosen reference amount, typically the selling price.

Formula used

Quote margin dollars = quoted selling price - required job cost
Quote margin = quote margin dollars ÷ quote reference amount × 100

Inputs explained

Quoted selling price:
Required job cost:
Quote reference amount:

How to use the result

Use it as the last step in building a quote, after you've totaled all job costs, to confirm the margin clears your shop's threshold.
It is only as good as the job cost you feed it; if tooling amortization, rework risk, or setup labor are understated, the margin will look better than the job actually delivers.
