Rust Upkeep Calculator
Estimate your base's daily tool cupboard upkeep.
1. Base Size
2. Total Build Cost
Sum of every resource spent building the base (your building blocks' own crafting costs already show this per-piece on each item's page).
Estimated Daily Upkeep
Assumes build cost is spread evenly across all blocks. A base with a few very expensive pieces (e.g. lots of doors/windows) mixed in with cheap ones will vary slightly from this estimate.
Decay Time Without Upkeep
| Grade | Hours to Fully Decay |
|---|---|
| Twig | 1.0 |
| Wood | 3.0 |
| Stone | 5.0 |
| Metal | 8.0 |
| Armored (Top Tier) | 12.0 |
Rates are Rust's own dedicated-server defaults (the decay.bracket_*/decay.duration_* ConVars), most servers run unmodified.
Upkeep is charged as a percentage of your base's total build cost, in the same resources it was built from, and that percentage rises the more blocks your base has.
If a server has changed these values, the real numbers there will differ from what's shown here.
The base upkeep calculator works out how much wood, stone, metal fragments and high quality metal your base costs per day from its block count and total build cost, using Rust's own default decay brackets.
