Calibration Cost Per Gauge with total annual calibration spend of 12,000 $: a worked example

This worked example runs the calibration cost per gauge numbers for a tougher week than the baseline: total annual calibration spend of 12,000 $ instead of the typical 24,000 $. Estimate the average calibration cost per gauge by dividing total calibration spend by the number of gauges in the program.

The inputs for this scenario

  • Total annual calibration spend: 12,000 $ (the input this scenario stresses; the baseline uses 24,000)
  • Active gauges in the calibration program: 160 gauges (held at the documented default)
  • Reporting conversion factor: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Calibration cost per gauge = total calibration spend รท gauges in the program.
  • Calibration cost per gauge works out to 75 $ / gauge at these inputs, and this is the headline figure for the scenario.
  • Raw ratio works out to 75 value at these inputs.
  • Conversion factor works out to 1 x at these inputs.
  • Gauges in the program works out to 160 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where total annual calibration spend sits at 24,000 $ and the headline result is 150 $ / gauge, this scenario comes in 50% below the baseline at 75 $ / gauge.
  • Use it during annual quality budgeting, when comparing in-house versus outsourced calibration, or when building a case to purge idle gauges from the calibration schedule. 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.

Results at a glance

  • Calibration cost per gauge: 75 $ / gauge (headline result)
  • Raw ratio: 75 value
  • Conversion factor: 1 x
  • Gauges in the program: 160 value
