Explo ammo counts assume every shot lands.

TL;DR C4 is the cheapest way through stone, sheet metal and armored walls. Explosive ammo is the cheapest way through every door, but only if every shot lands. A stone wall costs 4,400 sulfur (2 C4), a sheet metal wall 8,800 sulfur (4 C4) and an armored wall 17,600 sulfur (8 C4).

How to Use the Rust Raid Calculator

This Rust raid calculator prices a raid before you spend a single hour farming sulfur. Count what stands between you and the tool cupboard, add it to the calculator, and it tells you exactly what to craft.

Add your targets. Click a wall, door or deployable to add it to your raid. Click it again, or use the + and − buttons, to change the count.
Pick a boom type. Choose C4, rockets, satchels or explosive ammo to raid everything with one explosive, or leave it on Smart Mix to use the cheapest option for each target.
Read the total. The total sulfur cost updates live, along with how many of each explosive you need.
Open the farming bill. The Full Farming Bill lists every resource to gather, including charcoal, metal fragments, low grade fuel, cloth, tech trash, pipes and rope.

Scout firstWalk the base before you commit. Count the doors and walls on the shortest path to the TC, look for soft sides and weak doors, and price that path. The cheapest raid is almost never straight through the front.

The same numbers the calculator uses, for every target. The highlighted value is the cheapest explosive for that target, and the last column shows its sulfur cost.

Hit the weakest spotDoors are nearly always cheaper than the wall next to them. An armored door costs 6,250 sulfur in explo ammo, while the armored wall beside it costs 17,600 sulfur in C4. A sheet metal door is the cheapest way into most bases at 1,575 sulfur.

Sulfur Cost of Every Rust Explosive

Sulfur is the bottleneck in every raid, so it is the number that matters. Here is what one of each raiding explosive costs to craft.

2,200sulfur per C4

1,400sulfur per rocket

480sulfur per satchel

25sulfur per explo round

Explosive	Sulfur	Charcoal	Metal Frags	Other
C4	2,200	3,000	200	60 low grade, 5 cloth, 2 tech trash
Rocket	1,400	1,950	100	30 low grade, 2 metal pipes
Satchel Charge	480	720	80	10 cloth, 1 rope
Explosive Ammo	25	30	3	None

C4 vs Rockets vs Satchels vs Explo Ammo

C4 packs the most damage per sulfur against thick walls, which is why it wins on stone, sheet metal and armored walls. It also needs tech trash, so it is the hardest to mass craft early in a wipe.

Rockets cost more sulfur for the damage, but you fire them from range. That makes them the pick when you need to hit a high target or raid under fire, not when you are trying to save sulfur.

Satchels are cheap to unlock and only need cloth and rope, so they are the early wipe raiding tool. They are close to C4 on stone walls, but they can dud, so bring a spare.

Explosive ammo is the cheapest per sulfur against doors and wooden targets. The catch is volume: you need hundreds of rounds, a good rifle and time, and every missed shot costs you.

Soft Side Eco Raiding

Melee tools hit the soft side of building blocks around 10x harder than the hard side. If a builder left a soft side facing out, you can dig in for free. Here is the tool bill:

Target (Soft Side)	Tools Needed	Time
Wooden Wall	2 hatchets or 1 salvaged axe	~1 min
Stone Wall	7 pickaxes, 7 icepicks, or 1 jackhammer with 1 refill	~2 to 10 min
High External Wooden Wall	~7 tools	~16 min
High External Stone Wall	~5 jackhammers	~60+ min

The jackhammer trickJackhammers never break, they just run out of charge. Drop a portable workbench next to the wall and keep repairing one jackhammer forever. A stone wall soft side becomes a one tool job. Loud, but free.

Know when to walk awaySheet metal and armored blocks can’t realistically be eco raided. And the rule cuts both ways: on stone, the soft side looks smooth and pebbly while the hard side looks like fitted blocks. Scout before you commit your tools.

Rust Raiding Tips to Save Sulfur

Go through doors, not walls. A door is almost always the cheapest boom target on a raid path.
Use Smart Mix. Mixing C4 on walls with explo ammo on doors beats any single explosive type.
Kill the turrets first. An auto turret takes just 2 satchels (960 sulfur), far less than getting shot off the raid.
Watch the wipe timer. Bases are fullest just before a wipe and weakest just after. Raiding a few hours before the Rust force wipe means less loot to keep but fewer people online to defend.
Craft at a workbench. The costs here assume workbench-crafted explosives. Build everything ahead of time so the raid stays quick.

Rust Raid Calculator FAQ

How much sulfur does it take to raid a stone wall in Rust?

A stone wall has 500 HP and takes 2 C4 (4,400 sulfur), 4 rockets (5,600 sulfur), 10 satchels (4,800 sulfur) or 185 explosive ammo (4,625 sulfur). Two C4 is the cheapest option at 4,400 sulfur.

How much C4 does it take to break a sheet metal wall?

A sheet metal wall has 1,000 HP and takes 4 C4, which is 8,800 sulfur. Rockets need 8 (11,200 sulfur) and explosive ammo needs about 400 rounds (10,000 sulfur), so C4 is the cheapest boom for metal walls.

How many rockets does it take to raid an armored wall?

An armored wall has 2,000 HP and needs 15 rockets (21,000 sulfur). C4 is cheaper here: 8 C4 costs 17,600 sulfur.

What is the cheapest way to raid doors in Rust?

Explosive ammo is the cheapest boom for every door. A sheet metal door takes 63 explo ammo (1,575 sulfur), a garage door takes 150 (3,750 sulfur) and an armored door takes 250 (6,250 sulfur). You need a rifle and every shot has to land.

How much sulfur is in one C4, rocket and satchel?

One timed explosive charge (C4) costs 2,200 sulfur, one rocket costs 1,400 sulfur, one satchel charge costs 480 sulfur and one explosive 5.56 round costs 25 sulfur.

Is the Rust raid calculator accurate for modded servers?

The calculator uses vanilla values. Modded servers often change explosive damage, crafting costs or building HP, so treat the numbers as a baseline and check your server's rules.

What does Smart Mix mean in the raid calculator?

Smart Mix picks the cheapest explosive for each target on its own, then adds them up. It is usually cheaper than raiding everything with one boom type, and the calculator shows how much sulfur it saves.
