Upkeep Calculator
Count your blocks and get the exact wood, stone, fragments and HQM your cupboard eats every day.
OpenTools
Rust tools
Calculators and references for the things the game never tells you. Every one is free, none of them need an account or your Steam login, and none of them are metered. The game data behind them is versioned and dated, so what you get is the current patch rather than a number someone remembered from a wipe or two ago.

Every tool states where its numbers came from and when they were last checked. Rust is patched monthly; re-check anything critical after a force wipe.
Calculators
Decay Timer
How long a base survives with no upkeep, from its building grade and current health.

How to read these
Numbers, not vibes
The raid, electricity, FPS and console data all live in versioned modules with a provenance comment and a “last verified” date. Facepunch retunes explosive damage, deployable power draw and convar ranges in the monthly patch, so anything with a number in it is current-patch data rather than a permanent truth.
The wipe timer and genetics calculator are pure maths and do not go stale: force wipe is the first Thursday of the month at roughly 19:00 UTC, and the crossbreed weighting has held across every farming patch so far.
Server lookup is the one tool that talks to a third party. It reads BattleMetrics at request time and shows only what BattleMetrics actually tracks.
