Official answer
794,000
US dollars
How to estimate it
Fermi’s official “Napkin math”
Start with the iPhone. How many does Apple sell in a year? Maybe 200 million, at about $1,000 each. Phones feel like half the business, so double it, then spread it over the 525,600 minutes in a year.
- iPhones a year
- ~200,000,000
- $1,000 each, doubled for everything else
- ≈ $400 billion
- Minutes in a year
- ÷ 525,600
- $400B ÷ 525,600
- ≈ $760,000
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Apple net sales, fiscal 2025 (52 weeks ended Sept 27, 2025)
- $416,161 million
- Minutes in 52 weeks (364 × 1,440)
- ÷ 524,160
- $416,161M ÷ 524,160
- ≈ $794,000
