Plating Cost at 110% coverage requiring plating: a worked example

What does the result look like when coverage requiring plating reaches 110%? The full calculation is worked below with real intermediate numbers. A finishing buyer quoting a corrosion-resistant spring uses it to roll plating into the delivered piece price.

The inputs for this scenario

  • Parts plated in the lot: 30,000 parts (unchanged)
  • Plating cost per part: 0.05 $/part (unchanged)
  • Coverage requiring plating: 110 % (raised for this scenario; the documented default is 100)
  • Rack and bath setup charge: 175 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Plating cost = parts plated x plating cost per part x coverage% + setup charge) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,660 $ for total plating cost, the number this scenario is built around.
  • At this operating point the engine returns 0.06 $ / piece for plating cost per unit.
  • At this operating point the engine returns 1,485 $ for variable plating cost.
  • At this operating point the engine returns 175 $ for fixed plating cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where coverage requiring plating sits at 100% and the headline result is 1,525 $, this scenario comes in 8.85% above the baseline at 1,660 $.
  • A figure at this level is achievable when coverage requiring plating is genuinely sustained, not just peaked for a shift. It assumes one plating operation and a flat per-part rate; multi-layer stacks, reject re-plates, masking labor and thickness-driven metal draw are not modeled and must be added separately.

Results at a glance

  • Total plating cost: 1,660 $ (headline result)
  • Plating cost per unit: 0.06 $ / piece
  • Variable plating cost: 1,485 $
  • Fixed plating cost adder: 175 $
