Plan the raid. Count the cost. Farm the sulfur.
RaidCalc is three workbench-grade calculators for Rust raiders: price any target list explosive by explosive, find the sulfur-cheapest route, and see exactly how long the grind will take.
Three tools, one pipeline
Raid Cost Calculator
Pick walls, doors, garage doors, TC, turrets or SAM sites with quantities - get the exact C4, rocket, satchel, beancan, explosive-ammo, MLRS or torch count plus the sulfur bill.
Price a raid →Cheapest Raid Solver
Every way to kill your target, ranked by sulfur: “cheapest raid = 185 explosive rounds + 2 C4 = 7,550 sulfur” - with workbench tiers flagged.
Rank my options →Sulfur Farming ETA
Enter your sulfur-per-minute or nodes-per-hour and see the ETA, node count, ore and charcoal for the raid you planned.
Time the grind →The numbers everyone asks for
Computed from the same verified table the tools use - HP ÷ damage, rounded up.
| Target | HP | Rockets | C4 | Satchels | Cheapest route (sulfur) |
|---|---|---|---|---|---|
| Wooden Door | 200 | 1 | 1 | 2 | 19× Explo ammo = 475 |
| Sheet Metal Door | 250 | 2 | 1 | 4 | 63× Explo ammo = 1,575 |
| Garage Door | 600 | 3 | 2 | 9 | 150× Explo ammo = 3,750 |
| Stone Wall | 500 | 4 | 2 | 10 | 2× C4 = 4,400 |
| Sheet Metal Wall | 1,000 | 8 | 4 | 23 | 4× C4 = 8,800 |
| Armored Wall | 2,000 | 15 | 8 | 46 | 8× C4 = 17,600 |
| Tool Cupboard | 100 | 1 | 1 | 1 | 10× Explo ammo = 250 |

Why raiders keep RaidCalc open
Math you can audit
Every count is ceil(HP ÷ damage) from published wiki tables, cross-checked against the RustClash raid data. The methodology shows the receipts.
Tools that hand off
Price a raid → rank the routes → time the farm. Your target list follows you across all three calculators automatically.
No dark patterns
No account, no upload of your plans, no pop-ups over the calculator. If data is stale or disputed, the page says so.
Built mobile-first
Big steppers, mono numerals and one-thumb quantity tweaks - because the plan happens at the workbench, on a phone.
How RaidCalc works
- Pick targets in the raid cost calculator - quantities, and which side you can hit.
- Get the shopping list: units per explosive, sulfur per line, workbench flags, raid total in sulfur and nodes.
- Optimize: the solver re-ranks every explosive by sulfur for your exact list and quotes the cheapest mixed raid.
- Plan the farm: enter your rate, get the ETA and the node count. Then go take it.

Frequently asked questions
How many rockets does it take to break an armored wall?
15 rockets (2,000 HP ÷ 137.575 damage per rocket, rounded up) = 21,000 sulfur. Sheet metal walls take 8, stone walls 4, wood walls 2.
How much sulfur do I need for a typical raid?
A simple wood-or-sheet-metal base with a few doors usually dies for 2,000–8,000 sulfur; stone bases run 10,000–25,000; armored walls push past 60,000. Price your exact target list in the raid cost calculator instead of guessing.
What explosive is cheapest per damage?
Per sulfur, explosive 5.56 ammo and beancan grenades win on paper; satchels are the practical early-game pick; rockets are the all-rounder; C4 is for when you need speed or a T3 setup. The cheapest raid solver ranks them for each target, because the winner changes with wall tier.
Is RaidCalc free? Do I need an account?
Free, no sign-up, no ads covering the tools, and your raid plans never leave your browser - they live in local storage so you can hand a plan between the three calculators.
