Heat Treat Cost per Part Calculator

Price each finished part using the supplier’s actual minimum-charge structure. Enter the finished count, per-part quote, minimum and separate fee.

What this calculator does

  • Find the quoted cost per finished part after a minimum processing charge and separate batch fee.

Formula used

  • Variable processing = finished parts × processing rate
  • Processing charge = max(variable processing, minimum processing charge)
  • Lot cost = processing charge + separate batch fee
  • Cost per finished part = lot cost ÷ finished parts

Inputs explained

  • Finished Parts: Accepted finished count covered by this supplier quotation.
  • Processing Rate: Quoted processing price before any minimum charge.
  • Minimum Processing Charge: Supplier minimum excluding the separate batch fee.
  • Separate Batch Fee: Certification or setup fee outside the processing minimum.

How to use the result

  • Best suited to supplier minimum Comparison, small lot quote review.
  • This model excludes separately unquoted freight, rework and scrap. Minimum charges that include certification need a different fee allocation.

Current U.S. benchmarks

  • Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.

Common questions

  • Is the minimum added to the variable charge? No, the larger of the variable charge and processing minimum is used. The separate batch fee is then added once.
  • What if certification is included in the minimum? Enter zero for the separate fee unless another charge remains outside that minimum. Confirm the invoice structure with the processor.
  • Which part count belongs in the denominator? Use the finished parts covered by this quote. A load containing rejected parts needs a separate incurred-cost analysis.
  • Will doubling the lot halve the unit cost? Only the fixed contribution is diluted. Once variable processing exceeds the minimum, the per-part rate continues to apply to each part.
