QA Bottleneck Calculator
Is QA review keeping up with your inspections? Use this free calculator to estimate your QA review capacity based on reviewers, review time, and inspection volume — and see whether your review backlog is shrinking or growing.
Your Numbers
How many completed inspection records reach QA for review each month.
How many people review and approve inspection records.
Typical scheduled hours per week for each reviewer.
Share of the work week actually spent reviewing inspection records, after audits, meetings, and other QA duties.
Typical time to review one inspection record and approve or flag it.
How many inspection records are sitting in the QA review queue right now.

How the calculation works
This calculator compares how many inspection records your QA team can review each month with how many are submitted for review, then shows what that means for the records already waiting in the queue.
Review hours per month = reviewers × weekly hours × the share of time spent reviewing × 4.33 weeks/month (52 weeks ÷ 12 months). Monthly review capacity = review hours × 60 ÷ average minutes per review. Utilization = records submitted ÷ review capacity.
If capacity exceeds submitted volume, the difference is how fast the existing backlog shrinks each month, which gives the estimated time to clear it. If submitted volume exceeds capacity, the backlog grows by the difference every month and won't clear on its own.
This is a planning estimate, not a guarantee — it doesn't account for absences, review complexity that varies record to record, or records sent back for correction and re-review.
Realistic example
A QA team of 2 reviewers working 40 hours a week, with 30% of that time spent reviewing inspection records at about 5 minutes per review, can review roughly 1,250 records a month. With 1,000 records submitted each month, reviewers are at about 80% utilization, and a backlog of 200 records would take about 3.5 weeks to clear. If submitted volume grew 25%, review would be at capacity and the backlog would stop shrinking.
