Appliance Control Board Quote Margin Calculator with quoted control board selling price of 9.38 $ / board: a worked example

This worked example runs the appliance control board quote margin calculator numbers for a tougher week than the baseline: quoted control board selling price of 9.38 $ / board instead of the typical 18.75 $ / board. Calculate quote margin for appliance electronic assemblies from quoted selling price, estimated board cost, and margin reference amount.

The inputs for this scenario

  • Quoted control board selling price: 9.38 $ / board (the input this scenario stresses; the baseline uses 18.75)
  • Estimated total board cost: 14.25 $ / board (held at the documented default)
  • Margin reference price: 18.75 $ / board (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross margin per board = quoted control board selling price - estimated total board cost.
  • Quoted control board margin works out to -25.97 % at these inputs, and this is the headline figure for the scenario.
  • Gross margin per board works out to -4.87 $ / board at these inputs.
  • Quoted selling price works out to 9.38 $ / board at these inputs.
  • Estimated total board cost works out to 14.25 $ / board at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where quoted control board selling price sits at 18.75 $ / board and the headline result is 24 %, this scenario comes in 208% below the baseline at -25.97 %.
  • Use it when quoting a control board or PCBA program to an appliance OEM, before committing a firm per-board price. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
