Rust Raid Calculator
Add multiple Rust doors, walls, and deployables to one raid plan, then compare current full-method C4, rocket, satchel, and explosive-ammo reference routes. See sulfur, crafting resources, workbench requirements, target-by-target counts, and a shareable plan.

Plan a Complete Raid Path, Not Just One Wall
Add every independent layer you expect to break, including different doors, walls, gates, hatches, and deployables. A plan can contain several target types at once, so two sheet metal doors, one garage door, and a tool cupboard can be calculated as one raid instead of four separate lookups.
The calculator keeps each target quantity separate and then totals the required explosives for every supported full-method route.
Lowest Sulfur and Fewest Items Answer Different Questions
The lowest-sulfur result finds the available full-method route with the smallest raw sulfur total. The fewest-items result finds the route using the smallest number of explosive items.
Those results can be different. C4 uses relatively few items, while explosive ammunition can require many more rounds but use less sulfur on some targets.
Fewest items is not presented as the fastest raid. Real raid time depends on placement, reloads, weapon handling, fuse behaviour, movement, defenses, counters, and player execution.
See the Full Crafting Cost Behind the Boom
Sulfur alone does not tell you whether a raid route is practical. The calculator expands each explosive count into sulfur, charcoal, metal fragments, low-grade fuel, cloth, tech trash, metal pipes, and rope.
Resource totals cover the modeled crafting cost of the explosive items themselves. They do not include reusable equipment such as rocket launchers or rifles, workbench construction, research scrap, armor, healing, transportation, or replacement gear.
Crafting Resources per Explosive Item
Per-item totals used by the calculator after intermediate crafting recipes and recipe yields are expanded. Zero means that resource is not required for the modeled item.

Use Workbench Limits and a Safety Buffer
Set the highest workbench available to remove methods you cannot currently craft. Satchels remain available at Tier 1, while the reference model requires Tier 3 for C4, rockets, and explosive 5.56 ammunition.
The optional safety buffer increases the complete explosive count after all selected targets have been added, then rounds upward to a whole item. A 10% buffer on four rockets therefore becomes five rockets.
The buffer is a planning convenience, not a guarantee. Server rules, damaged structures, raid geometry, and the exact breach path can change what is actually required.
How the Conservative Raid Model Works
The calculator uses Vanilla Rust reference checked September 16, 2026. Each target stores a conservative full-method reference count for C4, rockets, satchels, and explosive ammunition.
Explosive-ammo counts use Semi-Automatic Rifle (conservative full-method planning reference). Explosive 5.56 structure damage varies by weapon, so the calculator does not treat one ammunition count as universally correct for every rifle.
The app multiplies each target's reference count by the selected quantity, adds the complete raid path together, applies the optional safety buffer, and calculates crafting-resource totals for each method.
Targets are treated independently. Rocket splash, shared damage, impact geometry, soft-side damage, partially damaged structures, fire damage, melee eco-raiding, and mixed explosive finishers are not automatically credited.
A carefully executed live raid can therefore cost less than the conservative result. The calculator is intended as a planning reference rather than a promise of the exact cheapest possible raid.
Rust Raid Target Reference per Independent Target
Conservative full-method reference counts used by the calculator before target quantity and safety buffer are applied. Explosive-ammo values use Semi-Automatic Rifle (conservative full-method planning reference). Rocket splash, mixed finishers, soft-side damage, and partially damaged targets are excluded.

Why Explosive Ammo Counts Can Differ Between Raid Guides
Explosive 5.56 Rifle Ammo does not produce one universal structure-damage result across every weapon. Different rifles can produce different required round counts against the same target.
Oliv ez uses Semi-Automatic Rifle (conservative full-method planning reference) so the calculator has one explicit and reproducible baseline instead of silently mixing values from different weapons.
If another current raid guide shows a different explosive-ammo count, check which rifle, target state, server configuration, and damage assumptions it uses before treating one value as incorrect.
Share a Raid Plan Without an Account
The Share button places the selected targets, workbench level, and safety buffer in the page URL. Opening that link restores the same raid plan without requiring an account.
Review a restored plan before relying on it, especially after a Rust update or when playing on a modded server.
Raid Count and Resource Formulas
The calculator totals the full-method reference count for each selected target, applies an optional percentage buffer to the complete route, rounds upward to a whole explosive item, and multiplies the result by the method's crafting resources.
Formula variables
- Explosive method being compared
- One selected raid target type
- Quantity selected for target i
- Reference items of method m required for one target i
- Base explosive count for the complete raid path
- Selected safety buffer percentage
- Whole explosive count after the buffer
- Per-item cost of resource r for method m
- Total amount of resource r
Examples
Compare a mixed door path
1Input
Targets: 2 sheet metal doors and 1 garage door; Workbench: Tier 3; Safety buffer: 0%.
Show result
Result
The full-method reference routes are 4 C4, 7 rockets, 17 satchels, or 276 explosive 5.56 rounds using the Semi-Automatic Rifle baseline. Explosive ammunition uses 6,900 sulfur, while 4 C4 is the fewest-item route.
This example shows why lowest sulfur and fewest explosive items are separate comparisons.
Plan a garage-door raid with Tier 1 access
2Input
Target: 1 garage door; Workbench: Tier 1; Safety buffer: 0%.
Show result
Result
The available modeled route is 9 satchel charges, requiring 4,320 sulfur, 6,480 charcoal, 720 metal fragments, 90 cloth, and 9 rope.
Tier 3 methods remain visible for comparison but are unavailable and cannot become the selected lowest-sulfur route.
Add a safety buffer to a stone-wall route
3Input
Target: 1 stone wall; method comparison: rockets; Safety buffer: 10%.
Show result
Result
The base count is 4 rockets. Applying a 10% buffer gives 4.4, which rounds upward to 5 rockets: 7,000 sulfur, 9,750 charcoal, 500 metal fragments, 150 low-grade fuel, and 10 metal pipes.
The buffer applies to the complete item count and rounds upward to a usable whole item.
Frequently Asked Questions
Can I add different Rust raid targets to one calculation?
Yes. Add any supported combination of doors, walls, gates, hatches, and deployables. The calculator totals the selected layers and keeps a target-by-target breakdown for every explosive method.
Does the calculator combine C4, rockets, satchels, and explosive ammo?
No. It compares complete single-method reference routes across the selected targets. Mixed explosive finishers can save resources in real raids, but the calculator does not automatically assume those combinations.
Does the Rust raid calculator include rocket splash damage?
No. Every selected target is treated independently. Rocket splash depends on spacing, impact position, line of sight, falloff, and base geometry, so shared damage is not assumed automatically.
Why can explosive-ammo counts differ between Rust raid calculators?
Explosive 5.56 structure damage can vary by weapon. This calculator uses Semi-Automatic Rifle (conservative full-method planning reference) as its explicit planning baseline rather than mixing counts from different rifles.
Why does the calculator sometimes show more explosives than a raid guide?
The reference table uses conservative full-method counts. Some guides use a rocket or C4 followed by a cheaper finisher, assume splash damage, target an already damaged structure, use a different rifle for explosive ammunition, or use different server settings.
What does the safety buffer do?
It increases the complete explosive count by the selected percentage and rounds upward. For example, four rockets with a 10% buffer becomes five rockets. Resource totals are calculated from the buffered count.
What is included in the crafting-resource totals?
The result includes sulfur, charcoal, metal fragments, low-grade fuel, cloth, tech trash, metal pipes, and rope used by the modeled explosive items. It does not include reusable weapons, launchers, workbenches, research scrap, armor, healing, or replacement gear.
How does the workbench setting affect the result?
Methods above the selected workbench tier cannot become the recommended route. In this model, satchels are available at Tier 1 while C4, rockets, and explosive 5.56 ammunition require Tier 3.
Will these values match modded Rust servers?
Not necessarily. The calculator is based on its stated vanilla reference. Mods, plugins, custom damage, crafting changes, and server-specific balance can change the live result.
Can I share my Rust raid plan?
Yes. The Share button creates a URL containing the selected targets, workbench level, and safety buffer. Opening that link restores the same calculator inputs without requiring an account.
