Frame Paint Scrap at 1.08% target maximum paint scrap rate: a worked example

Suppose target maximum paint scrap rate falls to 1.08%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate bicycle, e-bike, or scooter paint scrap from scrapped painted parts against inspected painted parts, with a target scrap rate.

The inputs for this scenario

  • Frames scrapped for paint defects: 18 parts (held at the documented default)
  • Painted frames inspected: 720 parts (held at the documented default)
  • Target maximum paint scrap rate: 1.08 % (the input this scenario stresses; the baseline uses 1.5)

Working through the calculation

  • The calculation starts from the formula this tool documents: Paint scrap rate = scrapped painted parts ÷ inspected painted parts × 100.
  • Paint scrap rate works out to 2.5 % paint scrap at these inputs, and this is the headline figure for the scenario.
  • Paint scrap gap to target works out to -1.42 points at these inputs.
  • Scrapped painted parts works out to 18 parts at these inputs.
  • Inspected painted parts works out to 720 parts at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target maximum paint scrap rate sits at 1.5% and the headline result is 2.5 % paint scrap, this scenario lands almost exactly on the baseline at 2.5 % paint scrap.
  • It computes the paint scrap rate as scrapped frames divided by inspected frames, then reports the gap in percentage points between that rate and your target. 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.

Results at a glance

  • Paint scrap rate: 2.5 % paint scrap (headline result)
  • Paint scrap gap to target: -1.42 points
  • Scrapped painted parts: 18 parts
  • Inspected painted parts: 720 parts

Run it with your numbers

  • To rerun this with your own numbers, open the live Frame Paint Scrap calculator, set target maximum paint scrap rate to your actual value, and adjust the remaining inputs to match your operation.
