Rust Base Design: Build, Upkeep and Raid Cost
What one piece of each grade costs to build and keep, how long it lasts without upkeep, and what it takes to raid. Light and sound reach is on its own page.
One piece by grade
| Grade | HP | Wall or foundationbuild, then upkeep a day | Triangle foundationbuild, then upkeep a day | Decays inno upkeep |
|---|---|---|---|---|
| 10 | 1 hour | |||
| 250 | 3 hours | |||
| 500 | 5 hours | |||
| 1,000 | 8 hours | |||
| 2,000 | 12 hours |
Upkeep is for one piece in a base of 15 pieces or fewer, per 24 hours. Decay is the time from full health to zero with no upkeep. A piece the base shelters on every side decays at 10% of that speed. Every other shape is on building grades.
Upkeep grows with base size
| Pieces in the base | Upkeep a day, share of build cost |
|---|---|
| 1 to 15 | 10% |
| 16 to 65 | 15% |
| 66 to 190 | 20% |
| 191 and up | 33.3% |
The cupboard averages these shares over every piece in the base and charges that average on each one: a base of 100 pieces pays 16% of each piece's build cost a day. Work out a whole base with the upkeep calculator.
Doors
| Door | HP | Upkeep a day | Decays inno upkeep |
|---|---|---|---|
| 200 | 3 hours | ||
| 250 | 8 hours | ||
| 600 | 8 hours | ||
| 1,000 | 12 hours | ||
| 1,000 | 12 hours |
Upkeep is per 24 hours and the same at any base size: doors are not blocks, so they never change the bracket.

How many it takes to break one target. Least of these is the one above with the least sulfur, with its total. Explosive ammo counts are for an Assault Rifle.

Tested in game on our own server: the upkeep a cupboard bills for each grade and door, and the time each grade and door takes to decay with no upkeep. Tested on the current version of Rust.

Rust base design: common questions
- Which building grade is hardest to raid in Rust?
- Armored. An armored wall has 2,000 HP, against 500 for stone. The raid table on this page shows how many rockets, C4 or satchels each one takes.
- How much upkeep does one stone wall cost?
- 30 Stones a day while the base has 15 pieces or fewer. A bigger base pays a higher share on every piece: at 100 pieces, 16% of each piece's build cost a day instead of 10%.
- How long does a base take to decay without upkeep?
- From full health: twig 1 hour, wood 3 hours, stone 5 hours, sheet metal 8 hours, armored 12 hours.
