Cheapest way to raid the common targets
The building blocks you actually raid, at a glance — the cheapest method by sulfur and the C4 count players ask for most. Every structure is broken down on the full raid chart.
| Target | HP | Cheapest | Sulfur | C4 |
|---|---|---|---|---|
| Sheet Metal Door | 250 | 63× Explosive 5.56 Ammo | 1,575 | 1 |
| Garage Door | 600 | 150× Explosive 5.56 Ammo | 3,750 | 2 |
| Armored Door | 1,000 | 250× Explosive 5.56 Ammo | 6,250 | 3 |
| Wooden Door | 200 | 1× Incendiary Rocket | 300 | 1 |
| Sheet Metal Wall | 1,000 | 4× Timed Explosive Charge | 8,800 | 4 |
| Stone Wall | 500 | 2× Timed Explosive Charge | 4,400 | 2 |
| Wooden Wall | 250 | 1× Incendiary Rocket | 300 | 1 |
| Armored Wall | 2,000 | 8× Timed Explosive Charge | 17,600 | 8 |
| Sheet Metal Double Door | 250 | 63× Explosive 5.56 Ammo | 1,575 | 1 |
| Tool Cupboard | 100 | 10× Explosive 5.56 Ammo | 250 | 1 |
Straight answers
Already know what you're breaking? These skip the calculator and just give you the number, the sulfur cost and whether there's a cheaper way.
Melee & softsiding
No boom? These count tools worn out rather than sulfur — and for walls the soft side is a different game entirely.
Fire — burning wood bases
Wood burns. Molotovs and fire arrows are the cheapest way through a wooden wall or door — thrown from range, no gunpowder needed.
How the numbers work
Every raid figure comes from one formula on Rust's own values: shots = HP ÷ (explosive damage × (1 − resistance)). These are datamined straight from the game.
Explosive damage
| C4 | 550 |
| Rocket | 275 |
| Satchel Charge | 75 |
| HV Rocket | 30 |
| Beancan Grenade | 15 |
Wall HP & explosion resist
| Tier | HP | Resist |
|---|---|---|
| Twig | 10 | 0% |
| Wood | 250 | 10% |
| Stone | 500 | 50% |
| Metal | 1,000 | 50% |
| Armored | 2,000 | 50% |
Worked example: a Stone Wall has 500 HP and 50% explosion resist, so each C4 (550 dmg) deals 275 → 500 ÷ 275 = 2 C4.

Raiding — common questions
How many C4 for a sheet metal door?expand_more
A Sheet Metal Door takes 1 C4 (about 2,200 sulfur). It's the fastest way in, though satchels are cheaper if you have the time — the calculator above ranks every method by sulfur cost.
How many C4 for a garage door?expand_more
A Garage Door takes 2 C4 (4,400 sulfur). Garage doors have no soft side, so you pay full price from either direction.
How many rockets for a stone wall?expand_more
A Stone Wall takes 4 rockets (5,600 sulfur) from the hard side. The cheapest method is actually 2× Timed Explosive Charge at 4,400 sulfur — always soft-side a wall if you can reach it.
What's the cheapest way to raid a sheet metal wall?expand_more
The cheapest way to break a Sheet Metal Wall is 4× Timed Explosive Charge for 8,800 sulfur (hard side). Hitting the soft interior side drops that by roughly a third — pick the wall and toggle the soft side in the calculator above.
How many satchels for a wooden door?expand_more
A Wooden Door takes 2 satchel charges (960 sulfur) — but at 200 HP a couple of hits from a decent melee weapon is cheaper still if you're not in a rush.
How many C4 for an armored wall?expand_more
An Armored Wall — the toughest building tier at 2,000 HP — takes 8 C4 (17,600 sulfur). This is why raiders almost always go through the cheaper walls or doors instead.
How is the raid cost calculated?expand_more
Every number comes from the community-tested Rust raid chart — the base explosive counts to destroy each structure at full HP — and is multiplied out for the quantity and softsided if you choose. Sulfur is the raw amount in each explosive's craft chain, so you can compare methods on true cost, not just item count.

Raiding something bigger?
This calculator prices one structure at a time across all 9 explosive methods, for any of the 27 targets in the data — walls, doors, deployables and vehicles. For a whole raid route, or for the craft cost behind the explosives, the sibling tools pick up where this one stops.
Add every wall and door on the route and total the explosives for the whole base at once.
What the explosives cost to craft — raw sulfur, charcoal and metal fragments per unit.
Tugboats, RHIBs and submarines — each hull has its own armour profile, not a shared one.
What these numbers cover
Counts are hard side — the exterior face — unless you flip the soft-side toggle. Interior faces take more damage, so a wall you can reach from inside costs meaningfully less than the same wall hit from outside.
The resource figures are the gunpowder chain: the raw sulfur, charcoal and metal fragments behind each explosive. They deliberately stop there. A rocket also needs a Metal Pipe and C4 needs tech trash and cloth, and we don't publish a number for those until it comes from the same sourced recipe data as everything else — an approximate figure in a raid plan is worse than no figure.
Vehicles are priced per hull rather than by applying one damage table to a health bar. Explosive damage against a Tugboat is not the same as against a Rowboat, so each entry is sourced individually. Torpedoes and cannonballs are absent for the same reason — no verified craft cost yet, so ranking them against the other methods would be a guess.
