ISO 9001 Audit Cost at 110% billable audit effort share: a worked example

This scenario runs the iso 9001 audit cost calculation on the strong side: 110% billable audit effort share, with every other input held at its documented default. A management representative budgets the upcoming ISO 9001 surveillance or recertification audit for the fiscal year.

The inputs for this scenario

  • Auditor-Days Required: 6 auditor-days (unchanged)
  • Certification Body Day Rate: 1,500 $/day (unchanged)
  • Billable Audit Effort Share: 110 % (raised for this scenario; the documented default is 100)
  • Certification & Prep Fees: 3,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total audit cost = auditor-days x day rate x billable share + certification and prep fees) to the inputs above produces each figure below.
  • At this operating point the engine returns 12,900 $ for total iso 9001 audit cost, the number this scenario is built around.
  • At this operating point the engine returns 2,150 $ / piece for iso 9001 audit cost per unit.
  • At this operating point the engine returns 9,900 $ for variable iso 9001 audit cost.
  • At this operating point the engine returns 3,000 $ for fixed iso 9001 audit cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where billable audit effort share sits at 100% and the headline result is 12,000 $, this scenario comes in 7.5% above the baseline at 12,900 $.
  • Use it when budgeting a Stage 1/Stage 2 certification, an annual surveillance visit, or a three-year recertification. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total iso 9001 audit cost: 12,900 $ (headline result)
