How to estimate it

Fermi’s official “Napkin math”

Most of the 40 squares on the board are for sale, so you are looking at about 28 deeds. What does the average one cost? The cheapest is $60, Boardwalk is $400, and the climb between them is steady, so call it $200.

Deeds on the board
≈ 28
Average price
≈ $200
28 × 200
≈ $5,600

Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.

Source calculation & reference
22 street deeds, from Mediterranean at $60 to Boardwalk at $400
$4,590
4 railroads at $200 each
$800
2 utilities at $150 each
$300
Total across all 28 deeds
$5,690
