How do you calculate gross margin on a 3D printing quote?

Subtract estimated job cost from the quoted selling price to get margin dollars, then divide by the reference price. A $6,200 quote minus $4,100 cost gives $2,100 in margin, which on a $6,200 reference price is a 33.9% gross margin.

What is a good gross margin for additive manufacturing work?

Bureaus commonly target 30-50% gross margin to cover overhead, build failures, and reinvestment. The 33.9% in this example is healthy but on the lower end, so there is little room for a build to fail or for cost to overrun.

What's the difference between margin dollars and margin percent?

Margin dollars ($2,100 here) is the absolute profit on the job; margin percent (33.9%) is that profit relative to the reference price. Two jobs can have the same percent but very different dollar contributions, so check both.

Why use a separate margin reference price instead of the selling price?

Usually the reference equals the selling price, giving standard gross margin. But you can set the reference to a list or target price to measure margin against what you should have charged, which is useful when discounting.

How do I improve margin on an AM quote?

Either raise the selling price or lower job cost, nest parts more densely to cut build time, reduce support material, or batch jobs to spread machine setup. Dropping the $4,100 cost to $3,800 would lift this quote's margin from 33.9% toward 39%.

Is gross margin the same as profit on a job?

No. Gross margin excludes overhead, sales cost, and the cost of failed builds. A 33.9% gross margin can become a thin net margin once a 10-15% build-failure allowance and shop overhead are applied.

Additive Manufacturing calculator

Additive Quote Margin Calculator

The additive quote price check tells you whether a 3D printing job is actually worth winning by converting your quote into a gross margin. AM estimators and sales engineers use it to sanity-check a number before it goes to the customer, because build-time and material estimates can drift and quietly erode margin. It takes your quoted selling price, your estimated job cost, and a reference price, then returns both the margin dollars and the margin percentage. On a busy bureau floor, this is the 30-second test that stops you from booking work below your target margin.

What this calculator does

Calculate gross margin for an additive manufacturing quote from sell price, estimated cost, and quote reference price.
a service bureau estimator needs to check whether a 3D printing quote is profitable
It computes gross margin in dollars and as a percentage from the quoted selling price, the estimated job cost, and a margin reference price.

Formula used

Margin dollars = quoted selling price - estimated job cost
Gross margin = margin dollars ÷ margin reference price

Inputs explained

Quoted AM selling price: undefined
Estimated AM job cost: undefined
Margin reference price: undefined

How to use the result

Use it right before sending an AM quote, or when reviewing booked jobs to see which ones cleared your margin floor.
It measures gross margin only, it ignores overhead, failed builds, and post-processing rework, so the true bottom-line margin is lower than this figure.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 292.875 (BLS, Jul 2026), up 10.7% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 22,301 printing and related support establishments employing about 386,248 workers (Census County Business Patterns, 2023).
