Tempering Cycle Cost at 65% cost capture rate: a worked example

Suppose cost capture rate falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate tempering cycle cost from batch size, per-part tempering rate, cost capture, and fixed furnace or certification adders.

The inputs for this scenario

  • Parts tempered per cycle: 250 parts (held at the documented default)
  • Tempering rate per part: 1.85 $/part (held at the documented default)
  • Cost capture rate: 65 % (the input this scenario stresses; the baseline uses 90)
  • Furnace and cert adder: 350 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total cost = parts tempered x tempering rate per part x cost capture% + furnace and cert adder.
  • Total tempering cycle cost works out to 651 $ at these inputs, and this is the headline figure for the scenario.
  • Tempering cost per part works out to 2.6 $ / part at these inputs.
  • Captured tempering cost works out to 301 $ at these inputs.
  • Fixed tempering cycle adder works out to 350 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where cost capture rate sits at 90% and the headline result is 766 $, this scenario comes in 15.09% below the baseline at 651 $.
  • It computes total tempering cycle cost as captured variable cost plus a fixed furnace/cert adder, then divides by parts to give cost per part. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Total tempering cycle cost: 651 $ (headline result)
