Inspection Capacity Calculator
How many inspections can your quality team handle each month? Use this free calculator to estimate inspection capacity based on available inspectors, inspection time, working hours, and required inspection volume.
Your Numbers
How many people perform inspections on your team.
Typical scheduled hours per week for each inspector.
Share of the work week actually spent performing inspections, after breaks, meetings, and other duties.
Typical hands-on time to complete one inspection, not including paperwork/admin afterward.
How many inspections your operation actually needs completed each month.

How the calculation works
This calculator estimates monthly inspection capacity from your available inspectors, their working hours, and how much of that time typically goes to inspection work versus other duties.
Available hours per inspector per month = weekly hours × the share of time spent on inspections × 4.33 weeks/month (52 weeks ÷ 12 months). Monthly capacity = total available hours across all inspectors × 60 ÷ average minutes per inspection.
This is a capacity estimate, not a guarantee — it doesn't account for absences, seasonal swings, or inspection complexity that varies inspection to inspection.
Realistic example
A team of 3 inspectors working 40 hours a week, with 70% of that time actually spent inspecting, completing an inspection every 12 minutes, has a theoretical monthly capacity of about 1,820 inspections. Against a requirement of 1,000 inspections a month, that's roughly 55% utilization — about 820 inspections a month of headroom before the team would be fully booked.
