Method
How we calculate this
No black box. Every figure comes from the inputs on this page, so you can test the assumptions yourself — and bring your real numbers to the demo.
- QA hours today
- calls a month × share reviewed × minutes per review ÷ 60
- 100% coverage by hand
- calls a month × minutes per review ÷ 60
- 100% coverage with COSA
- calls a month × share flagged × minutes per flagged review ÷ 60
- Reviewer cost
- hours a month × 12 × (salary ÷ 1680 hours a year)
The model counts reviewer time only. It doesn't try to put a number on avoided complaints, redress or regulatory action — and it leaves out COSA's subscription, which is priced on your call volume.
