Plating Batch Cost at 110% chargeable yield or pass-through factor: a worked example

What does the result look like when chargeable yield or pass-through factor reaches 110%? The full calculation is worked below with real intermediate numbers. Use it when quoting zinc, zinc-nickel, phosphate, black oxide, or other fastener coating work for a defined lot.

The inputs for this scenario

  • Chargeable fastener quantity or weight: 1,200 pieces or lb (unchanged)
  • Plating rate for that unit: 0.04 $ / unit (unchanged)
  • Chargeable yield or pass-through factor: 110 % (raised for this scenario; the documented default is 100)
  • Minimum lot, bake, or handling fee: 85 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Plating batch cost = chargeable quantity × plating rate × chargeable factor + fixed plating fee) to the inputs above produces each figure below.
  • At this operating point the engine returns 131 $ for total plating batch cost, the number this scenario is built around.
  • At this operating point the engine returns 0.11 $ / unit for plating cost per chargeable unit.
  • At this operating point the engine returns 46.2 $ for variable plating charge.
  • At this operating point the engine returns 85 $ for fixed plating fee.

How this compares with the baseline

  • Against the tool's baseline example, where chargeable yield or pass-through factor sits at 100% and the headline result is 127 $, this scenario comes in 3.31% above the baseline at 131 $.
  • A figure at this level is achievable when chargeable yield or pass-through factor is genuinely sustained, not just peaked for a shift. It uses one blended chargeable factor and one fixed fee, so it won't separately model masking, special racking, or certification charges — add those as their own line items.
