Does this set the required certification audit duration?

No. Certification audit duration and scope follow the applicable scheme and certification body process. This estimates only the entered labor scope.

Do interviews belong in the review pace?

Exclude them from the record review pace. Enter auditor interview labor separately so a two-person interview counts both auditors’ time.

Where should the follow-up percentage come from?

Use comparable completed reviews. Divide their additional follow-up labor by their base record review labor and multiply by 100.

Can fewer sampled records prove adequate audit coverage?

No. Sampling and evidence sufficiency depend on the approved audit plan and professional assessment, beyond this labor calculation.

AS9100 Evidence Review Workload Calculator

Plan labor for a defined AS9100 evidence review. Enter selected records, observed review pace, follow-up allowance, interview hours and your labor budget.

What this calculator does

Estimate auditor labor for evidence review, follow-up and planned interviews against your available budget.

Formula used

Review labor = records ÷ review pace ÷ 60
Follow-up labor = review labor × allowance ÷ 100
Total auditor labor = review + follow-up + interview labor
Labor margin = available budget − total auditor labor

Inputs explained

Evidence Records: Evidence items selected in your audit plan.
Evidence Review Pace: Observed evidence records reviewed per auditor minute.
Follow-Up Labor Allowance: Additional follow-up labor as a percentage of base review.
Planned Interview Labor: Auditor hours reserved for interviews, excluding record review.
Available Labor Budget: Hours reserved for this complete planned work scope.

How to use the result

Best suited to internal audit Planning, evidence review staffing.
This does not set certification audit duration or demonstrate AS9100 conformity. Review pace must be at least 0.001 records per minute. Margins within numerical precision are zero; equality does not confirm spare capacity.
