How to estimate it
Fermi’s official “Napkin math”
Start with Costco's stores, about 900 worldwide. That rotisserie case by the meat counter never seems to run out. Maybe 500 chickens roll out of each store a day, at about $5 apiece.
- Costco warehouses worldwide
- ≈ 900
- Chickens sold per store, per year (500/day × 365)
- ≈ 180,000
- Price each
- × $5
- 900 × 180,000 × $5
- ≈ $810,000,000
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Rotisserie chickens sold, fiscal 2025 (Costco Q4 earnings call)
- ≈ 157.4 million
- Price per chicken, unchanged since 2009
- × $4.99
- 157.4M × $4.99
- ≈ $785 million
