About RaidCalc
A free, independent toolkit for Rust raiders - built to make raid costs honest, checkable and fast to look up.
Why this site exists
Every Rust raider asks the same three questions: what will it cost, what’s the cheapest way, and how long will the sulfur take? The answers exist - scattered across wiki charts, Discord pins and spreadsheet folklore - and they quietly rot every time the game patches.
RaidCalc puts the three answers in one pipeline. The math is deliberately boring - ceil(HP ÷ damage) and count × sulfur - because boring math can be checked. Every dataset value cites its source, every reconciliation between disagreeing sources is documented, and the snapshot date tells you exactly how fresh the numbers are.
Who makes it
RaidCalc is built and maintained by a small team of long-time Rust players and web developers. We don’t publish personas or invented credentials - what we publish instead is method: every number on this site traces to a cited source, and the full reasoning lives on the methodology page. When a count is disputed or stale, we say so on the page rather than smoothing it over.
How it’s paid for
It isn’t. No ads, no affiliate links, no paywall, no account system. The tools run entirely in your browser; your raid plans are stored in your device’s local storage and are never uploaded. Hosting is a fixed cost we cover because we wanted the tool to exist.
Relationship with Facepunch
