Charcoal runs 23,966 short of what the recipe needs, so about 95,864 extra wood has to be burned to top it up.

Quick answers

Frequently asked questions

How much sulfur does it take to craft C4 in Rust?

A single Timed Explosive Charge needs 2,200 sulfur once the gunpowder and explosives underneath it are expanded. Set the target to C4 and a quantity to see the running total for a full raid load.

Does the planner count furnace time and wood?

Yes. Any raw material that comes from ore is routed through the furnace you pick. The tool sums the ore to smelt, the wood burned, and the charcoal that comes back as a byproduct before crafting begins.

Where do the node counts come from?

Yield per node is a planning average you can edit to match your server rate and tools. The gather figures then divide the raw total by the yield you set, so the node count reflects your own farm.

Is crafting time affected by my server?

Craft and smelt time both scale with the craft and gather rates saved in your wipe profile, so a modded server shows shorter times than a vanilla one.
