Plating Batch Cost at 72% chargeable yield or pass-through factor: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop chargeable yield or pass-through factor to 72%, then walk the calculation through step by step. Estimate outsourced or in-house plating batch cost from fastener lot weight or piece count, plating rate, chargeable factor, and fixed fees.

The inputs for this scenario

  • Chargeable fastener quantity or weight: 1,200 pieces or lb (held at the documented default)
  • Plating rate for that unit: 0.04 $ / unit (held at the documented default)
  • Chargeable yield or pass-through factor: 72 % (the input this scenario stresses; the baseline uses 100)
  • Minimum lot, bake, or handling fee: 85 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Plating batch cost = chargeable quantity × plating rate × chargeable factor + fixed plating fee.
  • Total plating batch cost works out to 115 $ at these inputs, and this is the headline figure for the scenario.
  • Plating cost per chargeable unit works out to 0.1 $ / unit at these inputs.
  • Variable plating charge works out to 30.24 $ at these inputs.
  • Fixed plating fee works out to 85 $ at these inputs.

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 9.26% below the baseline at 115 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to chargeable yield or pass-through factor, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. 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.
