RustRaid Calculator

Work out exactly how much boom you need. Add the doors, walls and deployables in your way, pick your explosive, and get the raw sulfur and full shopping list in seconds.

Raid with

Each structure is raided with its cheapest practical explosive (C4, rockets, satchels, beancans or fire).

Side hit

The weak face with the support frame, the side raiders aim for. Cheapest counts.

Sulfur needed

Load structures and the raw sulfur shows up here.

Counts are calculated from live in-game structure health and explosive damage, for the side you pick above. Facepunch tweaks values between updates, so treat these as a planning guide. Data verified July 2026.

How accurate is this

?

Every count is calculated straight from the game's own values: each structure's real in-game health and each explosive's actual damage, run through the same math the game uses (damage minus the structure's resistance, rounded up). Nothing is hand-typed, so the numbers re-derive themselves every wipe. Counts default to the weakest (soft) side, the cheapest way in, and the Soft / Hard toggle flips to the strong outer face.

The sulfur and full material list behind every explosive comes from its real craft recipe, walked all the way down (gunpowder to explosives to the finished charge), so a C4 really is 2,200 sulfur and a rocket 1,400. Most efficient mode then picks the cheapest practical explosive for each wall or door, so C4 handles sheet metal and armored, fire eats wood, and satchels cover early-wipe doors. It skips explosive ammo and HV rockets in auto: they win on raw sulfur but need a rifle and an online raid.

It depends on the structure and which side you hit. From the soft side it takes 1 C4 for a wood wall, 2 for stone, 4 for sheet metal, and 8 for an armored wall. Doors are cheaper: 1 C4 for a sheet metal door and 3 for an armored door. Add every wall, door and deployable in your path to this calculator and it totals the C4 (and raw sulfur) for you.
