Sulfur to break each structure
Total raw sulfur to destroy one of each, from the hard (exterior) side. The cheapest column is the one to plan around — it's frequently a different explosive from the one people assume.
| Structure | HP | Cheapest sulfur | via | C4 sulfur | Rocket sulfur |
|---|---|---|---|---|---|
| Wooden Door | 200 | 300 | 1× Incendiary Rocket | 2,200 | 1,400 |
| Sheet Metal Door | 250 | 1,575 | 63× Explosive 5.56 Ammo | 2,200 | 2,800 |
| Garage Door | 600 | 3,750 | 150× Explosive 5.56 Ammo | 4,400 | 4,200 |
| Armored Door | 1,000 | 6,250 | 250× Explosive 5.56 Ammo | 6,600 | 7,000 |
| Wooden Wall | 250 | 300 | 1× Incendiary Rocket | 2,200 | 2,800 |
| Stone Wall | 500 | 4,400 | 2× C4 | 4,400 | 5,600 |
| Sheet Metal Wall | 1,000 | 8,800 | 4× C4 | 8,800 | 11,200 |
| Armored Wall | 2,000 | 17,600 | 8× C4 | 17,600 | 21,000 |
| Tool Cupboard | 100 | 250 | 10× Explosive 5.56 Ammo | 2,200 | 1,400 |
Every structure, including vehicles and deployables, is broken down on the full raid chart.
Full craft cost per explosive
Raw materials to craft one of each, all the way down the gunpowder chain. Sulfur is what gates a raid, but charcoal and metal fragments are what actually stall the crafting — plan for all three.
| Explosive | Sulfur | Charcoal | Metal frags | Sulfur ×10 |
|---|---|---|---|---|
| C4 | 2,200 | 3,000 | 200 | 22,000 |
| Rocket | 1,400 | 1,900 | 146 | 14,000 |
| Satchel Charge | 480 | 660 | 80 | 4,800 |
| Beancan Grenade | 120 | 180 | 20 | 1,200 |
| Explosive 5.56 Ammo | 25 | 38 | 5 | 250 |
| High Velocity Rocket | 200 | 300 | — | 2,000 |
| Incendiary Rocket | 300 | 450 | — | 3,000 |
| Propane Explosive Bomb | 900 | 1,350 | — | 9,000 |
| F1 Grenade | 60 | 90 | 25 | 600 |
A dash under metal fragments means the recipe needs a different component instead (a Metal Pipe, for example) rather than raw fragments.

Sulfur — common questions
How much sulfur for 1 rocket?expand_more
1 Rocket costs 1,400 sulfur to craft. That's the raw sulfur in the full recipe chain (via gunpowder) — the calculator above adds it up automatically for however many you need.
How much sulfur for 4 satchels?expand_more
4 Satchel Charges cost 1,920 sulfur — 480 sulfur per satchel.
How much sulfur for 10 satchels?expand_more
10 Satchel Charges cost 4,800 sulfur — the amount you'd need for most stone walls (see the table above for the exact figure per structure).
How much sulfur for 1 C4?expand_more
1 Timed Explosive Charge (C4) costs 2,200 sulfur to craft — the most sulfur-expensive explosive per unit, but usually the fewest units needed since it hits hardest.
How much sulfur for explosive 5.56 ammo?expand_more
1 round of Explosive 5.56 Rifle Ammo costs 25 sulfur, so a 100-round stack is 2,500 sulfur. It's the cheapest sulfur per unit of any explosive, but it takes far more rounds to break anything, so the total often isn't cheaper.
Do I need charcoal as well as sulfur?expand_more
Yes — every explosive runs through gunpowder, which needs charcoal alongside the sulfur. 1 Rocket takes 1,400 sulfur and 1,900 charcoal; 1 C4 takes 2,200 sulfur and 3,000 charcoal. Charcoal comes free from burning wood in a furnace while you smelt, which is why raid planning is usually sulfur-limited rather than charcoal-limited.
