Tool Sharpening, Reconditioning & Industrial Repair Services worked example

Repair Margin with recondition price quoted to customer of 63 units: a worked example in tool sharpening, reconditioning & industrial repair services

Here is what the math looks like when conditions slip. We hold every other input steady and drop recondition price quoted to customer to 63 units, then walk the calculation through step by step. Repair margin is the profit left after you subtract the full cost of reconditioning a tool from the price you charge the customer.

The inputs for this scenario

  • Recondition price quoted to customer: 63 units (the input this scenario stresses; the baseline uses 125)
  • Total cost to recondition the tool: 100 units (held at the documented default)
  • Reference base for margin (usually price or cost): 100 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Repair Margin margin = available value - required value.
  • Margin works out to -37 % at these inputs, and this is the headline figure for the scenario.
  • Absolute margin works out to -37 value at these inputs.
  • Available amount works out to 63 value at these inputs.
  • Required amount works out to 100 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where recondition price quoted to customer sits at 125 units and the headline result is 25 %, this scenario comes in 248% below the baseline at -37 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to recondition price quoted to customer, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The percent depends entirely on which reference base you pick — dividing by price gives gross margin, dividing by cost gives markup, and the two are not interchangeable.
