Rust Furnace Calculator | AR Rust Hub

Calculate Rust smelting time, wood or power needs, and per-furnace ore splits.

  • Split ore across furnaces without waste.
  • Estimate smelting time and fuel demand fast.
  • Adjust around wood and power constraints before crafting.

Interactive calculators, live lookups, and authenticated features become available after the client app loads.

How it works

  1. Choose small, large, or electric furnace mode.
  2. Enter ore amount, furnace count, and an optional target finish time.
  3. Use the load distribution table to copy practical split rows.

Data and methodology

Furnace results are formula-based estimates for slots, active furnaces, smelt timing, fuel, charcoal, and electric power.

FAQ

Why are some furnaces idle?
Tiny batches can finish with fewer active furnaces, so idle furnaces are excluded from finish estimates.
Does the table scroll on mobile?
Only the detailed split table scrolls horizontally; the page itself should not.
