About MinecraftCalc
MinecraftCalc is a free, fan-built enchantment planner for Minecraft Java Edition. It computes a lower-cost anvil order so you avoid the dreaded “Too Expensive!” cap and save tens of XP levels per piece of gear.
What you can do here
- Plan combos for the 24 enchantable item types (sword, pickaxe, bow, spear, mace, elytra, shield, etc.) - see all items.
- Compare all 43 enchantments including Spear + Lunge and the Mace additions (Density, Breach, Wind Burst) - see all enchantments.
- Read practical guides on anvil mechanics, prior-work penalty, villager trading, and bookshelf layouts - guides hub.
How accurate is the math?
The calculator core is a TypeScript port of the open-source
SJAR04/Minecraft-Enchanter
(MIT license). It implements the documented anvil cost formula -
including base enchantment cost, prior-work penalty 2^n - 1,
and the level-40 “Too Expensive!” cap on survival mode.
The live calculator is scoped to Java Edition planning with current
spear and mace enchantment data; it does not claim to simulate Bedrock,
modded, datapack, or snapshot rules.
