How to use the Rust Raid Calculator
- Add your targets. Search for a wall, door or deployable and press Enter. Add as many as you need and set the quantity for each.
- Choose how to raid. Use the cheapest mix, or force a single explosive such as C4 only if that is all you have.
- Read the total. You get the sulfur cost, the number of each explosive, and a comparison of every method.
- Check your budget. Enter the sulfur you hold to see if you have enough, or how far short you are.
How the numbers are worked out
Every wall and door has a health value, and each explosive does a fixed amount of damage to it. Targets resist explosives differently, which is why the count for the same explosive can differ between two targets with the same health. Satchels and explosive ammo are measured from the number of items each target is known to take.
Sulfur costs used are 2,200 for C4, 1,400 for a rocket, 480 for a satchel charge and 25 for each round of explosive 5.56 ammo.
What the cheapest mix does
It tries every combination of C4, rockets and satchels for each target and fills any remaining health with explosive ammo, then picks the one with the lowest sulfur cost. For a stone wall that comes out to one C4 plus 84 rounds of explosive ammo, which is cheaper than the two C4 you would use on its own.
Good to know
- Explosive ammo assumes every shot lands. Plan a few extra for misses.
- Floors and ceilings have the same health as walls of the same tier, so use the matching wall.
- Servers with plugins or changed settings can alter raid damage, so check your server's rules.
- Game updates sometimes rebalance explosives. We review these numbers when that happens.
Frequently asked questions
Which raid method is cheapest?
It depends on the target. Explosive ammo is cheapest for doors and weak walls if you can land every shot, while C4 is cheapest for stone, metal and armored walls. The compare table shows the exact totals for your list.
Do these numbers apply to the soft side too?
Yes. Explosives do the same damage from either side, so the counts apply to both.
Why is a mix cheaper than a single explosive?
A single explosive often wastes damage on the last item. A mix uses a big explosive for most of the health and cheap ammo for the remainder.
Are vehicles and turrets included?
Not yet. This version covers walls, doors, bars, hatches and tool cupboards.
Is this the number I need to grind?
Yes. The sulfur total is the raw sulfur used to craft the explosives, so it is the figure to farm toward.
