About MinecraftCalc

MinecraftCalc is a free, fan-built enchantment planner for Minecraft Java Edition. It computes a lower-cost anvil order and see whether any required step exceeds the survival limit. Some inputs have no survival-feasible plan.

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 original calculator began as a TypeScript port of the open-source SJAR04/Minecraft-Enchanter (MIT license). The ordered subset search and validation were revised on October 18, 2026. 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 data checked against Java 26.3 (2026-09-15); it does not claim to simulate Bedrock, modded, datapack, or snapshot rules.
