CALCULATOR · ANVIL
Minecraft Anvil Calculator
Put the item in slot one and the books in slot two, on the page, before you do it in survival. Each printed step is one anvil use with its XP cost and the item you would take out.
Anvil calculator
Up to 8 books · Level cost · Survival capPick the gear you want to enchant. Books you add below will be merged onto it in the cheapest order we can find.
Worked example: pickaxe combine
Inputs: Fresh pickaxe (prior-work 0); Efficiency V book; Unbreaking III book; Silk Touch book. First anvil use is the Efficiency V book onto a fresh pickaxe: base cost 5, prior-work penalty 0, total 5 levels. Result: Pickaxe (Efficiency V), prior-work 1.
The full plan then folds Unbreaking III and Silk Touch into that pickaxe. Total for the tree: 16 levels, with every step under the survival cap.
- Combine Pickaxe with Book (Silk Touch I) 4 levels
- Combine Pickaxe (Silk Touch I), prior-work 1 with Book (Unbreaking III) 4 levels
- Combine Pickaxe (Silk Touch I, Unbreaking III), prior-work 2 with Book (Efficiency V) 8 levels
Failure case: Silk Touch and Fortune
Inputs: fresh pickaxe, Efficiency V, Fortune III, Silk Touch. The planner returns Fortune conflicts with Silk Touch. Choose one; this planner preserves every requested enchantment.. Those two enchantments cannot share a pickaxe, so no anvil order exists.
If the combine is legal but still refused in survival, switch to the XP cost calculator and check the 40-level cap. For merge-tree order, use the enchantment order calculator.
FAQ
- What does the anvil calculator show?
- Each step is one anvil use: the current target, the sacrificed book, the XP cost for that use, and whether survival would print Too Expensive. The final line is the item you would take out of the anvil.
- Do sacrificed tools cost the same as books?
- No. The Java item multiplier and book multiplier differ. Thorns III contributes 12 levels from a fresh book; its item-enchantment contribution would be 24 before other charges. This tool accepts books as sacrifices and does not model equipment repairs.
- Can I combine two enchanted pickaxes?
- Yes in Java Edition, if the enchantments do not conflict. This page's live tool models books onto an item. The planner preserves all requested enchantments, so it rejects a Silk Touch and Fortune bundle rather than silently discarding one. Actual item-to-item repairs and conflict handling are outside this tool.
- Which edition is modeled?
- Java Edition 26.3 book planning with pinned spear and mace data. Check the final combine in-game for Bedrock, mods, datapacks, or snapshots.
Data and method
Compatibility, maximum levels and anvil multipliers are checked against Java Edition 26.3 (released 2026-09-15). The enchantment definitions (anvil cost, maximum level, supported items, exclusive sets) and the table, trade and loot tags are the same as in 1.21.11. The book fee is half the definition’s anvil_cost, rounded down with a minimum of one, multiplied by the resulting enchantment level. Prior-work penalties are added separately.
These are worked planning examples and editorial loadout choices, not claims of in-game testing or guaranteed match results. The calculator handles an unenchanted target and up to eight single-enchantment book rows; it does not model repair materials, renaming, mods or newer version changes.
