Work out exactly what it costs to raid a Rust base. Set how many of each wall and door you need to get through, and this calculator shows the rockets, C4, satchel charges, beancans or explosive 5.56 required — and the total sulfur for each method, so you can pick the cheapest raid. Costs are for the strong (hard) side, rounded up to whole explosives.

Set a quantity above to see the totals. The cheapest method by sulfur is highlighted in green.
Sulfur is the raw, fully-broken-down craft cost per explosive: Rocket 1,400 · C4 2,200 · Satchel 480 · Beancan 120 · Explosive 5.56 25 (per round). Raid values are hard-side, verified against RustLabs / wiki.rustclash (2026 build). Building and raiding get rebalanced most wipes, so treat these as a close guide and confirm against the current patch.
Every design in our gallery already lists its full build cost, upkeep and rockets to raid, so you can pick a base with a high raid-cost-to-build ratio without calculating anything. Browse by team size: solo, duo, trio, quad and clan bases — or filter by raid cost and budget on the home page. New to bunkers? See the Rust bunker guide.
Want to design a layout, not just price a raid? Here's how the popular Rust base builders and planners compare. Most are free but desktop-heavy or early-access; the paid one (FORTIFY) is the most complete. None of them link a design straight to its build and raid cost the way our gallery does.
