Inspection Cost Per Part with total inspection cost of 1,100 $: a worked example

What does the result look like when total inspection cost reaches 1,100 $? The full calculation is worked below with real intermediate numbers. Use it when comparing inspection methods, justifying automation, or loading inspection cost into a quote.

The inputs for this scenario

  • Total inspection cost: 1,100 $ (raised for this scenario; the documented default is 450)
  • Parts inspected: 600 parts (unchanged)
  • Reporting conversion factor: 1 x (unchanged)

Working through the calculation

  • Applying the documented formula (Inspection cost per part = total inspection cost รท parts inspected) to the inputs above produces each figure below.
  • At this operating point the engine returns 1.83 $ / part for inspection cost per part, the number this scenario is built around.
  • At this operating point the engine returns 1.83 value for raw ratio.
  • At this operating point the engine returns 1 x for conversion factor.
  • At this operating point the engine returns 600 value for parts inspected.

How this compares with the baseline

  • Against the tool's baseline example, where total inspection cost sits at 450 $ and the headline result is 0.75 $ / part, this scenario comes in 144% above the baseline at 1.83 $ / part.
  • A figure at this level is achievable when total inspection cost is genuinely sustained, not just peaked for a shift. A single blended cost per part hides the difference between a fast go/no-go gage check and a full CMM layout; mixing inspection types in one number can mislead unless you separate them.

Results at a glance

  • Inspection cost per part: 1.83 $ / part (headline result)
  • Raw ratio: 1.83 value
  • Conversion factor: 1 x
  • Parts inspected: 600 value
