IATF 16949 Audit Day Calculation Application

The Audit Day Calculation Application is based on IATF Rules 6th Edition sections 5.2 - 5.4 requirements for determining the minimum audit days required to accomplish a complete and effective IATF 16949 audit of the organization's quality management system. The application does not consider every requirement impacting the minimum audit day calculation, especially where additional audit time is required.

Furthermore, the application uses the apportionment method for determining the minimum audit days for an organization that has standalone remote support location(s). The apportionment method is the method used most by IATF-recognized certification bodies. Another calculation method is permitted per IATF Rules 6th Edition, section 5.2.3, but it is not used in this application for calculating minimum audit days.

Section 2

Applicable Audit Day Reductions:

Mark all that apply per manufacturing site
Mfg.Site Name Currently IATF 16949 Certified No Design Responsibility Corporate Scheme Upgrade from ISO 9001 Upgrade from LOC Reapply for LOC
Reduction Amount N/A -15% -15% -30% -30% -30%
Note 1: The applicable audit day reductions listed above are based on the IATF Rules 6th Edition section 5.3 and 5.4.
Note 2: When combining reductions, the maximum possible audit day reduction is thirty percent (30%).


Section 3

Apportionment Method for SA-RSL Employees to Each Manufacturing Site:

This section is not applicable because there are no Standalone Remote Support Locations identified in Section 1.
Mfg.Site Name Number of Employees Apportionment Ratio Apportioned Employees from SA-RSL Total Employees
Total (Rounded):


To calculate the SA-RSL employee apportionment ratio:
  1. Sum the total number of employees at each manufacturing site.
  2. Divide the sum of employees at all manufacturing sites by the number of employees at each manufacturing site, separately. This results in the apportionment ratio to be used for determining the number of SA-RSL employees apportioned to each manufacturing site.
  3. Multiply the number of SA-RSL employees for each SA-RSL by the apportionment ratio for each manufacturing site, separately. This results in the number of employees apportioned from the SA-RSL(s) to each manufacturing site it supports.
  4. Sum the number of employees from the manufacturing site and the apportioned number of employees from SA-RSL to get the total number of employees used for the minimum audit day calculation in Section 4.


Section 4

Minimum Audit Day Breakdown:

Note 1: The minimum audit days is determined based on the number of employees entered Section 1 – 3, where applicable and using the IATF Rules 6th Edition, Table 5.2. The reduction percentages are calculated based on the responses in Section 2 above and following IATF Rules 6th Edition requirements. When combining all reductions from Section 2, the maximum reduction allowed is 30%.
Note 2: Final Audit Days are rounded up to the nearest .5 day.
Note 3: CBs may increase the final audit days by .5 days for each audit type for off-site audit planning, per Rules 5.7.
Note 4: Assumes no changes in number of employees or other changes over the 3-year audit cycle.
