NPI, DFM/DFA & Engineering Change calculator

First Article Cost Calculator

Estimate first article cost for npi, dfm/dfa and engineering change using production-ready inputs so teams can estimate total exposure, compare scenarios, or decide whether the cost is material to the quote. Quantity times rate times capture factor, plus a fixed adjustment, builds a defensible weighted cost.

What this calculator does

  • Estimate first article cost for npi, dfm/dfa and engineering change using production-ready inputs so teams can estimate total exposure, compare scenarios, or decide whether the cost is material to the quote.
  • Use it when first article cost in npi, dfm/dfa and engineering change is being put through a npi, dfm/dfa and engineering change weighted-cost review.
  • Turns first article cost quantity, first article cost or rate, first article cost scope or occurrence share into a weighted cost for first article cost in npi, dfm/dfa and engineering change.

Formula used

  • Variable first article cost = first article cost quantity × first article cost or rate × first article cost scope or occurrence share
  • Total first article cost = variable first article cost + fixed first article cost adder

Inputs explained

  • First article cost quantity: Enter the unit, assembly, claim, test, hour, or event count covered by the estimate.
  • First article cost or rate: Use the current supplier quote, BOM cost, labor rate, warranty cost, utility rate, or production cost basis.
  • First article cost scope or occurrence share: Enter the percentage of the population, build, claim set, or cost scope that this estimate should include.
  • Fixed first article cost adder: Add setup, tooling, validation, freight, engineering, containment, or program cost not captured per unit.

How to use the result

  • Use it when first article cost in npi, dfm/dfa and engineering change is being scored for capture or weighted cost.
  • Risk-adjustments and discount rates are not in the formula; layer them on top for capital reviews.

Common questions

  • How does this first article cost calculator help my npi, dfm/dfa and engineering change team? Estimate first article cost for npi, dfm/dfa and engineering change using production-ready inputs so teams can estimate total exposure, compare scenarios, or decide whether the cost is material to the quote. You get a weighted cost you can defend before quoting, scheduling, or sign-off.
  • Which inputs change the weighted cost the most? first article cost quantity, first article cost or rate, first article cost scope or occurrence share usually move the weighted cost most. Pull from measured npi, dfm/dfa and engineering change runs, supplier data, and recent quotes rather than memory.
  • How should I act on the output? Use the weighted cost in the npi, dfm/dfa and engineering change business case or quote build-up.
  • What should I double-check before acting? Confirm the capture factor is honest; over-stated capture is the most common reason these models miss.
