Rust Raid Costs: How Many C4, Rockets and Satchels per Wall and Door

You have spent two evenings farming sulfur, there is a base across the valley with a garage door and what looks like a sheet metal wall behind it, and the question is simple: is what you have enough? Guess wrong and you blow your whole stack on the outer wall and walk home empty-handed. Raiding in Rust is arithmetic before it is anything else.

Every raid tool is really an amount of sulfur, and the cheapest way in is almost always through doors, not walls. One C4 costs 2,200 sulfur, a rocket 1,400, a satchel 480 and an explosive 5.56 round 25. A sheet metal door falls to one C4, an armored wall needs eight.

This guide is for players planning their first real raids. It gives the current number of C4, rockets, satchels and explosive rounds for the common doors and walls, the sulfur behind each, and how to use those numbers to pick a route. The figures were checked against item pages verified for the build Facepunch released on 5 November 2026 and against a second chart; where the two give a range, so does this guide.

How raid costs are counted

Players count raids in sulfur because sulfur is the slow part. Charcoal comes from burning wood, metal fragments and cloth are everywhere, but every explosive in the game is built on gun powder and sulfur, and sulfur ore is what you have to go out and mine.

Every number below assumes the same three things:

• The door or wall is at full health. A wall someone already hit, or that is decaying, needs less.
• Every charge lands. A rocket that clips the edge or a satchel that rolls away does not count.
• You are attacking from outside, with explosives. Melee tools and fire are a different game.

What each explosive costs in sulfur

The sulfur cost comes from the crafting chain. Gun powder is made from 30 charcoal and 20 sulfur for 10 powder, so each gun powder is worth 2 sulfur. Everything else is built on top of that:

• Explosives: 50 gun powder, 3 low grade fuel, 10 sulfur and 10 metal fragments. That is 110 sulfur each.
• Timed Explosive Charge (C4): 20 explosives, 5 cloth and 2 tech trash. 2,200 sulfur. Workbench Level 3.
• Rocket: 10 explosives, 150 gun powder and 2 metal pipes. 1,400 sulfur. Workbench Level 3, and you need a rocket launcher.
• Satchel Charge: 4 beancan grenades, 1 small stash and 1 rope. Each beancan is 60 gun powder and 20 metal fragments, so a satchel is 480 sulfur. Workbench Level 1.
• Explosive 5.56 Rifle Ammo: 20 gun powder, 10 sulfur and 10 metal fragments for 2 rounds. 25 sulfur per round. Workbench Level 3, and you need a 5.56 rifle.

The mixing table makes gun powder with less charcoal, but the sulfur stays the same, so none of these totals change. Since the November 2026 update, unlocking these blueprints on the tech trees costs blueprint fragments, pages and books instead of scrap; researching a blueprint you found still costs scrap at the research table.

Raid costs for doors

Doors are the weak point of almost every base, and the numbers show why.

Double doors take the same as a single door of the same material: a sheet metal double door is still one C4 or four satchels. The explosive round count moves a little with the rifle and the distance, which is why the wooden door shows a range.

Raid costs for walls

Walls are where raids get expensive. These are the three grades you will meet on any base worth raiding:

Compare the bottom rows of both tables. An armored door, the best door in the game, costs three C4. A sheet metal wall, a mid-grade wall, costs four. That single comparison is most of raid planning.

The cheapest tool for each target

Multiply the counts by the sulfur per item and the cheapest option changes from target to target:

• Sheet Metal Door: explosive ammo 1,575, satchels 1,920, C4 2,200, rockets 2,800.
• Garage Door: explosive ammo 3,750, rockets 4,200, satchels 4,320, C4 4,400.
• Armored Door: explosive ammo 6,250, C4 6,600, rockets 7,000, satchels 7,200.
• Stone Wall: C4 4,400, explosive ammo 4,625, satchels 4,800, rockets 5,600.
• Sheet Metal Wall: C4 8,800, explosive ammo 10,000, satchels 11,040, rockets 11,200.
• Armored Wall: C4 17,600, explosive ammo 19,975, rockets 21,000, satchels 22,080.

Two patterns stand out. Explosive ammo is the cheapest way through doors, and C4 is the cheapest way through walls. Rockets are never the cheapest on these targets; you pay for them because they reach a door from a distance or a high window without anyone standing at the wall.

Cheap is not the same as fast. On an armored door, three C4 take about 16 seconds; 250 explosive rounds through a semi-automatic rifle take close to two minutes, loudly, while the owners log in. Many raiders use explosive ammo on the first door and save C4 for the doors deeper inside, where time matters more.

Planning a raid: count the path

The base itself decides the bill. Before you craft anything:

1. Find the tool cupboard, or your best guess. Loot is usually near it, and destroying it is what takes building privilege away from the owners.
2. Count every layer on the way. Write the route down: garage door, then sheet metal door, then armored door, for example.
3. Price each layer and compare with walls. If one route goes through three doors and another through two sheet metal walls, the doors almost always win.
4. Add a margin. Bring at least one spare charge per layer for misses, duds and a door that turns out to be armored.

A worked example: a garage door, a sheet metal door and an armored door to the cupboard. With C4 only that is 2 + 1 + 3 = 6 C4, 13,200 sulfur. With explosive ammo on the first door and C4 for the rest it is 3,750 + 2,200 + 6,600 = 12,550 sulfur, and the slow, cheap part happens on the outer door, while the fast C4 is kept for the inside. Going through two sheet metal walls instead of those doors would cost 8 C4 for the walls alone.

What changes the numbers

• Satchels can dud. A fair share fail to go off. You can walk up and try to pick a dud up again, and now and then one goes off by itself, so never stand over it. Beancan grenades, which satchels are made of, burn a different fuse length every time.
• Bullets lose damage with distance. Explosive rounds from far away need more shots than from close up.
• Owners repair. A wall half destroyed and then repaired is back to full, and so is your bill.
• Building grade matters more than the pieces. A stone wall upgraded to sheet metal doubles its cost; a wall left at wood or stone behind a strong door is an invitation.
• Small fixes in November 2026. Triangle frames no longer take splash damage through walls in some placements, and the battering ram stopped hitting tool cupboards through walls in October.

All of this is vanilla Rust. Modded servers can change explosive damage, crafting costs or add raid protection while owners are offline, so read the server’s rules before you farm 20,000 sulfur for a raid that is not allowed.

The checklist

• Sulfur per item: C4 2,200, rocket 1,400, satchel 480, explosive round 25.
• Doors: wooden 1 C4, sheet metal 1 C4, garage 2 C4, armored 3 C4.
• Walls: stone 2 C4, sheet metal 4 C4, armored 8 C4.
• Explosive ammo is cheapest on doors, C4 cheapest on walls, rockets buy reach rather than savings.
• The route to the cupboard is counted and priced before crafting, with a spare per layer.
• You know your server’s raid rules.

Where Badgyver comes in

I make custom Rust maps, and the map decides where people build and how they reach each other’s bases: open valleys, cliffs, monuments to hide behind. Maps like RATS 2, where over 71% of the land is buildable, give a server plenty of bases to build and plenty to raid. If you are looking for a server that suits the way you raid, the free Rust server list here is a good place to start.
