560,000,000
consoles
How to estimate it
Fermi’s official “Napkin math”
There have been five PlayStations. The PS2 is the best-selling console ever, maybe 150 million. The others sold less, so call it 100 million each on average.
- PlayStation home consoles
- 5
- Average sold per console
- × 100,000,000
- 5 × 100M
- ≈ 500,000,000
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- PS1 + PS2
- 102.4M + 160M
- PS3 + PS4
- 87.4M + 117.2M
- PS5 (to June 30, 2026)
- 95.3M
- Total
- ≈ 562,000,000
Reference cited by Fermi: Sony Interactive business data: PS1 102.4M, PS2 160M, PS3 87.4M, PS4 117M, PS5 95M+
