Minecraft Enchantment Calculator

About the Enchantment Calculator

Putting seven or eight enchantments on one sword or chestplate takes several trips to the anvil. Every trip makes the next one more expensive, because the anvil adds a prior work penalty each time an item or book is used. Combine books in the wrong order and the last step can jump past 39 levels and get blocked. This enchantment order calculator tries every legal merge order and gives you the one with the lowest total cost.

What you get on this page:

• Cheapest merge order: every legal anvil order is checked, and the lowest total wins
• Left and right slots: each step says exactly what goes where
• Level cost per step: plus the total, the most expensive step, and the XP points
• Conflict check: enchantments that can’t go together are greyed out
• Every item: swords, axes, tools, mace, bow, crossbow, trident, armor, elytra, fishing rod, shears and shields

How to Use the Enchantment Calculator

Step 1: Choose Your Item

Pick the item you want to enchant, like a Netherite sword or Diamond boots. The list only shows the enchantments that item can take.

Step 2: Tick Your Enchantment Books

Check every enchanted book you have and set its level, like Sharpness V or Unbreaking III. Conflicting choices are greyed out, so you can’t pick Silk Touch and Fortune together.

Step 3: Follow the Steps

The calculator lists each anvil step in order. Put the first item in the left slot and the second one in the right slot, pay the levels, and move to the next step.

Step 4: Check the Total

Under the steps you’ll see the total level cost, the most expensive single step, and how many anvil uses the item has afterward. Make sure you have enough levels for the biggest step before you start.

Why Anvil Order Matters

Each time an item or book goes through an anvil, its prior work penalty grows: 0, 1, 3, 7, 15, 31 levels. Both the left and right item add their penalty to the cost. If you stack books onto your sword one by one, the sword’s penalty doubles every time and the last books get very expensive.

The trick is to merge books in pairs first, then merge the pairs, so every item goes through the anvil as few times as possible. That’s a balanced merge order, and it’s what the calculator builds for you.

How Anvil Costs Are Calculated

The cost of one anvil step in Java Edition is:

• Enchantment cost of the item in the right slot: each enchantment’s level times its multiplier
• Plus the prior work penalty of the left item
• Plus the prior work penalty of the right item

Books have lower multipliers than items, which is why you always combine books and put them on the item, not the other way around.

Too Expensive: the 40 Level Limit

In Survival, any anvil step that costs 40 levels or more shows Too Expensive and can’t be done. The calculator only returns orders where every step stays at 39 levels or less. If no order works, it tells you, and you need to drop an enchantment or use fewer books.

Which Enchantments Can’t Be Combined

Best Enchantment Order for a Netherite Sword

A full sword usually means Sharpness V, Unbreaking III, Mending, Looting III, Sweeping Edge III, Fire Aspect II and Knockback II. With fresh books, the calculator finds an order where no step costs more than 15 levels, so you can do it all from about level 15. Tick those seven books with Sword selected to see the exact steps.

Best Enchantment Order for Armor

For boots, the common set is Protection IV, Feather Falling IV, Depth Strider III, Soul Speed III, Unbreaking III, Mending and Thorns III. Thorns and Soul Speed have a high multiplier, so they cost more. The calculator puts them in steps where the penalty is still low.

Tips to Save XP

• Get max-level books first: combining two lower books costs extra trips.
• Use the enchanting table for the item: a level 30 enchant from the table costs only 3 levels and gives the item free enchantments.
• Merge books, not items: sacrificing an enchanted item costs double the multiplier.
• Rename last: renaming adds cost and also counts as an anvil use.
• Get Mending from villagers: a librarian can sell a Mending book for emeralds.

Can the Prior Work Penalty Be Reset?

Yes. A grindstone removes all non-curse enchantments and resets the penalty to zero. You lose the enchantments, so it only helps if you plan to start over with books.

Java and Bedrock Anvil Costs

The calculator uses Java Edition rules. Bedrock Edition uses the same merge idea and the same 40 level limit, but it calculates some costs differently, so a few steps can be cheaper or more expensive on Bedrock. The order still works well as a plan on Bedrock.
