Additive Manufacturing Service Bureau Quoting calculator

AM Order Profitability Calculator

Order profitability is the dollar contribution a single additive manufacturing job leaves on the table after variable material, machine and labor costs are covered. Service bureau estimators and shop owners use it to decide whether a quote is worth running, how much discount room exists, and which customers actually fund the overhead. Unlike a flat markup, this view ties profit to the contribution each printed part or billable build hour generates, then layers in any fixed per-order profit such as a setup or rush fee. It is the number that separates a busy print farm from a profitable one.

What this calculator does

  • Estimate additive order profit contribution from accepted parts or hours, contribution rate, billable capture, and fixed profit adjustments.
  • a service bureau owner or quoting manager needs to judge whether an order is worth accepting
  • It computes the total dollar contribution an additive order generates from its sellable units, per-unit margin, the share of that margin you actually capture after concessions, plus any fixed profit add.

Formula used

  • Captured contribution = sellable units × contribution per unit × profitability capture
  • Order profitability basis = captured contribution + fixed profit adjustment

Inputs explained

  • Sellable parts or billable print hours:
  • Contribution margin per part or print hour:
  • Margin capture rate after discounts:
  • Fixed setup and post-processing profit add:

How to use the result

  • Use it when reviewing a quote before it goes out, comparing two jobs competing for the same build plate, or setting a floor price below which an order should be declined.
  • It assumes your per-unit contribution margin is already net of true variable cost; if material waste, support removal time or failed-print scrap are missing from that figure, the profitability shown will be optimistic.

Current U.S. benchmarks

  • The producer price index for plastic resins and materials stands at 319.371 (BLS, May 2026), up 19.5% from a year earlier. Quotes priced off last quarter's material cost miss this move.
  • 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.

Common questions

  • How do you calculate order profitability for a 3D printing job? Multiply sellable units by contribution per unit to get gross contribution, multiply by your capture rate, then add any fixed profit. With 65 parts at $22 contribution, 100% capture and a $380 fixed add, captured contribution is $1,430 and total order profitability is $1,810.
  • What is a good contribution margin per part for an AM service bureau? Most healthy bureaus target $15-$40 contribution per part on production resin and SLS work after material and machine time, or 35-55% of sell price. The $22 per part in the worked example sits in a typical range for mid-volume nylon parts.
  • What does margin capture rate mean here? It is the share of nominal contribution you keep after volume discounts, negotiated concessions and giveaways. At 100% you capture full margin; drop it to 85% and the same 65-part order yields only about $1,216 of captured contribution before the fixed add.
  • Contribution margin vs gross profit, which should I quote on? Quote variable decisions on contribution margin because fixed machine depreciation does not change whether you run one more order. Use gross profit for annual P&L. This tool deliberately works in contribution terms so a partially-loaded build still looks correctly profitable.
  • Why add a fixed profit adjustment instead of folding it into per-unit margin? Setup, slicing, build-plate prep and rush surcharges do not scale with part count, so spreading a $380 fee across 65 parts distorts your per-part economics. Keeping it as a fixed add keeps the per-unit margin clean for comparing different order sizes.
