Calculator
Formula Used
Total health = target health × target quantity.
Raw damage = damage per hit + extra splash or fire damage.
Effective damage = raw damage × hit rate × (1 − resistance).
Base ammo = ceiling(total health ÷ effective damage).
Total ammo = ceiling(base ammo × (1 + waste margin)).
Craft batches = ceiling(additional ammo needed ÷ ammo yield per batch).
Resources = craft batches × resource cost per batch.
How To Use This Calculator
- Select a target preset or use custom values.
- Enter target health and target quantity.
- Set expected damage per explosive ammo hit.
- Add hit rate, resistance, and waste margin.
- Enter available ammo and crafting values.
- Press calculate to view ammo, resources, stacks, and time.
- Use CSV or PDF buttons to save the result.

Rust Explosive Ammo Planning Guide
What This Calculator Does
This calculator helps Rust players estimate explosive rifle ammo for a planned virtual raid. It does not claim one fixed raid chart. Rust updates, server settings, weapon choice, and missed shots can change the final count. The tool lets you edit every key value, so the answer matches your own test data.
Why Editable Damage Matters
Explosive ammo damage can feel different across surfaces and situations. A door, wall, hatch, or deployable may absorb shots differently. Range, spread, recoil, and splash placement also matter. For that reason, the calculator asks for target health and effective damage per hit. You can use your own server testing, a trusted raid chart, or conservative practice numbers.
Resource Planning
A raid usually fails because players bring too little material, not because the formula is hard. This page estimates required rounds, extra craft batches, surplus rounds, stacks, reloads, sulfur, gunpowder, metal fragments, and craft time. Available ammo is included. That lets you separate ammo already stored from ammo that still needs crafting.
Waste and Accuracy
The waste field is useful for real play. Add a margin when shooting under pressure, fighting counters, or damaging grouped targets. Hit rate lowers damage when you expect misses. Resistance lowers damage when your chosen target or ruleset reduces explosive effect. These fields make the result more realistic than a simple health divided by damage shortcut.
How To Use Results
Start with one target. Enter health, quantity, and damage per hit. Keep a modest waste value. Then submit the form. Review total ammo first. Check batches next, because batch yield can create spare rounds. Compare from-scratch cost with additional crafting cost. Export the report when planning with teammates. Test values after game updates or on modded servers.
Practical Raid Notes
This calculator is for planning in a game. It is not a combat guarantee. Carry extra ammunition, tools, and protection. Consider noise, travel time, respawns, replacement weapons, and escape routes. Save several plans for different targets. Update presets when a server wipes, mods change, or a balance patch lands. A clean spreadsheet or PDF can help a group agree on loadouts before leaving base. Better planning reduces confusion, wasted resources, and improves shared raid decisions clearly.
FAQs
What does this calculator estimate?
It estimates explosive ammo, craft batches, resources, stacks, reloads, and crafting time for Rust raid planning.
Are the preset values official raid numbers?
No. They are editable planning examples. Rust updates, servers, weapons, and test methods can change actual values.
Why is there a waste margin?
Waste margin covers missed shots, bad angles, splash loss, counters, panic shooting, and unexpected target repairs.
What is effective damage?
Effective damage is adjusted damage after hit rate and resistance are applied. It is the working damage used in the formula.
Why do batches create surplus ammo?
Ammo is crafted in batches. If the needed amount does not divide evenly by yield, extra rounds remain after crafting.
Can I use this for modded servers?
Yes. Change health, damage, resource cost, yield, stack size, and craft speed to match your server settings.
What does available ammo mean?
Available ammo is the explosive ammo already stored. The calculator subtracts it before estimating new crafting needs.
Why export CSV or PDF?
CSV helps with spreadsheets. PDF helps share a clean raid plan with teammates before gathering resources.
