Industrial Equipment, Machinery & Capital Goods calculator

Custom Option Cost Calculator

Use this calculator to estimate the cost of custom options on industrial equipment. It helps estimators separate repeatable option cost from one-time engineering, validation, procurement, and documentation effort.

What this calculator does

  • Estimate custom option cost from optioned machines, option cost per machine, option adoption share, and fixed design or validation cost.
  • Use it when pricing nonstandard guards, controls, tooling, motors, drives, sensors, documentation, or customer requested features.
  • The result estimates cost for a custom machine option or option family.

Formula used

  • Variable custom option cost = machines with the custom option × option cost per machine × option adoption or quote share
  • Total custom option cost = variable custom option cost + fixed option design and validation cost

Inputs explained

  • Machines with the custom option: Count machines, cells, skids, or systems that include the nonstandard option.
  • Option cost per machine: Include purchased components, fabrication, controls changes, assembly labor, testing, and option specific materials.
  • Option adoption or quote share: Use expected take rate, awarded share, or the portion of the project carrying this option.
  • Fixed option design and validation cost: Include design work, risk assessment, supplier qualification, test procedure updates, and customer documentation.

How to use the result

  • Use it to price options, decide whether to standardize a feature, and review option profitability.
  • It depends on design reuse, supplier pricing, controls changes, and customer acceptance requirements.

Common questions

  • What is the custom option cost calculator for? It estimates the cost of nonstandard machine options or customer requested features.
  • What information should I enter? Use optioned machine count, option cost per machine, adoption share, and fixed option design cost.
  • What does the result tell me? The result helps decide whether option pricing covers both recurring and nonrecurring cost.
  • When is the result only an estimate? It is only an estimate when option scope, supplier cost, testing, or design reuse changes.
