How to Calculate Raid Cost for Your Rust Base
Raid cost tells you how expensive it is for someone to break into your base. Learn how to calculate it in rockets, C4, and satchels — and how to maximize it.
One of the most important questions in Rust is: how expensive is my base to raid? The answer — your raid cost — determines whether griefers and casual raiders skip your base or target it. Understanding and maximizing this number is one of the best things you can do for your survival.
The Three Main Raiding Tools
Most raids in Rust happen with one of three explosive types:
Rockets
The standard raiding tool. Rockets deal 350 damage per hit to stone walls (485 HP). This means you need roughly 2 rockets per stone wall. For metal walls (1000 HP), you need 4 rockets. For HQM walls (500 HP), about 2 rockets.
- Cost to craft: 1,400 sulfur per rocket
- Best for: Large raids, efficient damage per sulfur
C4 (Timed Explosive Charge)
C4 deals more damage per charge than rockets but costs more sulfur. One C4 deals 550 damage to stone walls. Most raiders use a mix of C4 and rockets depending on the situation.
- Cost to craft: 2,200 sulfur per C4
- Best for: Hard sides, tight spaces where rockets splash inefficiently
Satchel Charges
Satchels are the budget option. They deal ~75 damage each and have a chance to dud. You need 10–12 satchels to break a stone wall. They're unreliable but accessible early game.
- Cost to craft: 480 sulfur per satchel
- Best for: Early game raiding, offline targets with no online defense
How to Calculate Your Base's Raid Cost
Step 1: Count the weakest path to your loot room. Raiders always take the path of least resistance — they won't raid through your HQM walls if there's a stone wall shortcut.
Step 2: Add up the walls along that path. Count every wall, floor, or door they'd need to break.
Step 3: Multiply by the raid cost per building piece:
- Stone wall: ~2 rockets / 1 C4 / 10 satchels
- Metal wall: ~4 rockets / 2 C4 / 23 satchels
- HQM wall: ~2 rockets / 1 C4 / 10 satchels (same HP as stone but bullet resistant)
- Sheet metal door: ~1 rocket / 0.5 C4
- Garage door: ~2 rockets / 1 C4
- Armored door: ~4 rockets / 2 C4
Always calculate your raid cost from the outside in — take the path a raider would take, not the path you use to access your loot.
How to Increase Your Raid Cost
- Upgrade your walls — HQM walls cost the same as stone in rockets but are much harder to damage with bullets and fire.
- Add honeycomb — every extra wall layer forces raiders to spend more explosives.
- Use armored doors on your TC room — armored doors cost 4 rockets vs 1 for sheet metal.
- Separate your loot — if raiders have to go through multiple rooms, each costs extra explosives.
- Use hard sides — the 'soft side' of a wall takes double damage. Build so raiders always hit the hard side.
Raid Cost in Sulfur Terms
To compare different explosive options, convert everything to sulfur:
- 1 rocket = 1,400 sulfur to craft
- 1 C4 = 2,200 sulfur to craft
- 1 satchel = 480 sulfur to craft
A base that costs 10 rockets to raid requires 14,000 sulfur worth of explosives. That's a significant investment — most casual raiders will skip it.
A base that costs 20 rockets needs 28,000 sulfur — that's a large group commitment. At this point, your base is likely online-raid proof for most of the server.
