Abrasive Blasting, Shot Peening & Surface Prep worked example

Blast Quote Margin with quoted job price of 9,300 $: a worked example

Suppose quoted job price falls to 9,300 $. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate gross margin percentage from quoted surface prep price, estimated job cost, and quote price reference.

The inputs for this scenario

  • Quoted job price: 9,300 $ (the input this scenario stresses; the baseline uses 18,500)
  • Estimated blast job cost: 13,200 $ (held at the documented default)
  • Margin reference price: 18,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross margin dollars = quoted job price - estimated blast job cost.
  • Gross margin works out to -21.08 % gross margin at these inputs, and this is the headline figure for the scenario.
  • Margin dollars works out to -3,900 $ at these inputs.
  • Quoted price works out to 9,300 $ at these inputs.
  • Estimated job cost works out to 13,200 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where quoted job price sits at 18,500 $ and the headline result is 28.65 % gross margin, this scenario comes in 174% below the baseline at -21.08 % gross margin.
  • It computes gross margin dollars (quoted price minus estimated job cost) and the gross margin percent against a reference price for a blasting or surface-prep job. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
