Rust Decay & Upkeep Calculator
Tune your server's base decay settings. Adjust decay.scale, upkeep period, and bracket cost fractions — see how long bases survive without a Tool Cupboard and preview upkeep costs for different base sizes.
Decay Settings
Global multiplier on all decay timers. 0 = no decay, 1.0 = default, 2.0 = twice as fast.
How often upkeep is consumed from the TC. Default = 1440 (24 hours).
Upkeep Bracket Settings
Cost fraction increases as base block count crosses each bracket threshold.
| Bracket | Block Count Threshold | Cost Fraction |
|---|---|---|
| 0 | ||
| 1 | ||
| 2 | ||
| 3 |
Base Decay Timers (no TC, unprotected)

Upkeep Cost Examples
Approximate upkeep consumed per period based on bracket settings.
| Base Size | Blocks | Effective Cost Fraction | Period |
|---|---|---|---|
| Solo (small) | 25 | 10 % | 24.0 hr |
| 2-3 Man (mid) | 80 | 15 % | 24.0 hr |
