# how the numbers are calculated
All math is transparent and conservative. You can audit every formula in the source of this page.
- Total pages / year = engineers × pages/engineer/week × 52
- Toil pages / year = total pages × toil %
- Annual toil hours = toil pages × (minutes/page ÷ 60)
- Annual toil cost = toil hours × hourly rate
- OnCallReady savings = annual toil cost (assumes ~95% auto-resolution rate on toil pages)
- Net savings = savings − $3,588 (Pro subscription, $299/mo × 12)
- Payback period = $3,588 ÷ (savings ÷ 365) days
