Equal Mend Calculator
Equal Mend Calculator is a Fabric client-side HUD that works out the maximum equal durability an armor set can reach with mending from experience bottles.
What it does
The HUD reads the current durability of each of the four armor pieces, the number of experience bottles in the inventory, and the armor mending enchantment. From these it estimates how many bottles are needed to bring the set to an equal durability, within a maximum difference of 10 points between pieces.
Each experience bottle gives between 3 and 11 experience points, a random value, so the result is not exact: the displayed figure can differ from what the game produces. The calculation depends on two key factors, the armor durability and the bottle yield, and the HUD only shows its estimate when the armor mending enchantment is present. Cloth Config API is required for the settings screen, and Mod Menu is required to open it from the game menu.
The mod runs on the client alone. Players install it on Fabric; servers do not need it. Files exist for 1.21.1 and 1.21.11, and the latest Fabric build is 1.0.0 for 1.21.11, published 2026-09-20. The code is released under the MIT License, but the project is not open source.
Key features
Equal durability estimate
The HUD shows the number of experience bottles needed to bring all four armor pieces to a shared durability level.
Mending-only display
The HUD appears only when the armor mending enchantment is present, so it stays out of the way otherwise.
Always-on or bottle-only view
The HUD can stay visible at all times or show only while an experience bottle is held, set through the options.
Random yield noted
Because each bottle gives a random 3 to 11 experience points, the estimate is a guide rather than an exact value.

What the author says
A lightweight, client-side HUD that calculates the maximum equal durability you can reach on all 4 of your armor pieces, based on the current durability of each armor piece and the number of XP bottles in your inventory. Each XP bottle gives you 3-11 experience points (RNG) which is not a fixed value meaning the…
