Upkeep chart
What one block costs to keep per day at each grade and base size, and how long each grade lasts once the Tool Cupboard runs dry.
The game has no fixed upkeep for a block: every piece pays the same share of its cost per 24 hours, and that share grows with the size of the base. A half-size piece, such as a floor, pays half.
Costs and HP from the game files of Rust build 25797961, upkeep and decay rules from the server settings and the patch notes; compiled 2 Nov 2026.
