EVE Online reprocessing calculator

Paste modules, ships, ammo, ore or ice copied from your hangar and see exactly what comes out at your skills - and whether reprocessing pays more than selling the items as they are.

How the yield is calculated

Modules, ships, ammo and everything else reprocess at 50% × (1 + 2% × Scrapmetal Processing) - 55% at level V. Structures, rigs and implants do not change it.
Ore, moon ore and ice: (50% + rig) × (1 + system bonus, only with a rig) × (1 + structure) × (1 + 3% × Reprocessing) × (1 + 2% × Reprocessing Efficiency) × (1 + 2% × the ore's own processing skill) × (1 + implant). Athanor adds 2%, Tatara 5.5%; low-sec adds 6% and null-sec or wormhole space 12%.
Batches. Items reprocess in whole batches - one module, 100 units of ore or ammo. What does not make a batch stays in your hangar, and the calculator says how much.
Rounding and tax. Each material is rounded down for the whole stack, as in the game, and the reprocessing tax is taken from what comes out.

Need minerals instead? The ore reprocessing planner picks the cheapest compressed ore for them.
