Enchant Calculator

by Wolftifact

Enchant Calculator is a Fabric client mod that works out the cheapest order for combining enchantments on an anvil.

FabricClient-side onlyMIT LicenseOpen source1.21 – 26.3

What it does

Players open an anvil, place an item in the first slot, and pick the enchantments they want. The mod then shows the exact order in which to combine the books, with the levels each step costs. Its search covers combining several enchanted books before applying them, and it accounts for the prior work penalty that builds up with each anvil use, so it considers the true cost of each step rather than a rule of thumb.

The mod is aimed at survival play, where an anvil refuses any combination costing 40 levels or more and the order of combining books matters a great deal. It knows which enchantments fit the item, and it takes into account modded datapack enchantments with real costs and conflicts. Pressing the mode button above the plan switches the quantity the plan tries to reduce. Enchant Calculator requires Fabric API, and it is published for Fabric only, across 17 release versions 1.21 – 26.3, under the MIT License and open source.

Enchant Calculator is a client-side only mod, so only the player's client needs it and servers run without it. Its latest Fabric file is 2.0.0+26.3, published 2026-09-23.

Key features

  1. Cheapest combination order

    The search finds the order of anvil combinations with the lowest total cost, including the penalty for each step.

  2. Enchantment panel

    A left panel lists the enchantments that fit the item in the first anvil slot, so choices can be made quickly.

  3. Book handling

    Enchanted books are treated as a separate step, and the plan accounts for books combined before the item is used.

  4. Adaptive screen layout

    When the screen is narrow or the GUI scale is large, the side panels combine into a single tabbed panel, and any panel can be hidden and later reopened.

  5. Resource pack colours

    Panels take colours from the anvil texture, so dark resource packs produce dark panels.
