Heat Exchanger, Coil & Radiator Manufacturing calculator

Cost Per Coil Calculator

Use this calculator to build a practical cost per coil from material, labor, outside processing, burden, and setup assumptions. It helps estimators compare product variants and catch quote gaps before pricing is released.

What this calculator does

  • Estimate cost per coil or radiator assembly from build quantity, variable cost per unit, cost capture factor, and fixed setup or tooling cost.
  • Use it when quoting HVAC coils, radiators, condensers, evaporators, oil coolers, or heat exchanger assemblies and you need a fast unit cost build-up.
  • Builds a unit cost estimate from quote quantity, variable coil cost, capture factor, and fixed setup or tooling cost.

Formula used

  • Total captured coil cost = coils in quote lot × variable cost per coil × cost capture factor + fixed setup or tooling cost
  • Estimated cost per coil = total captured coil cost ÷ coils in quote lot

Inputs explained

  • Coils in quote lot: undefined
  • Variable cost per coil: undefined
  • Cost capture factor: undefined
  • Fixed setup or tooling cost: undefined

How to use the result

  • Use it for early quoting, make-buy comparisons, customer negotiations, and cost reviews before a full routing or ERP cost roll-up is available.
  • It does not replace detailed BOM costing. Material surcharges, scrap, freight, margin, warranty, and customer tooling terms may need separate lines.

Common questions

  • What should variable cost per coil include? Include material, direct labor, consumables, outside processing, and variable burden that scales with each coil if those costs are part of your quote basis.
  • Why include a fixed setup or tooling cost? It spreads setup, programming, fixtures, tooling, documentation, or engineering cost across the quote lot so low-volume jobs are not underpriced.
  • How should I use the cost per coil? Use it as an internal cost basis before applying margin, commercial terms, freight, warranty allowance, and customer-specific pricing rules.
  • When is this too simple? Use a full cost roll-up when tube material, fin stock, headers, manifolds, brazing, testing, packaging, and labor all vary by option or revision.
