Calculation Formula

Armor reduction:

eff = armor − armor² / (armor×4 + toughness×8 + 8×dmg)

reduction_armor = eff / 25 (max 80%)

Enchantment reduction:

reduction_enc = EPF × 4 / 100 (max 80%)

EPF = sum of effective protection levels

Total reduction (Java):

final = dmg × (1 − armor_reduction) × (1 − enc_reduction)

each reduction is individually capped at 80%

How to Use the Armor Calculator

Enter the raw damage of the attack and your max health, choose the damage type (physical, projectile, fire, explosion, fall, or magic), and assemble your armor by selecting the material for each piece. The toughness is automatically calculated based on equipped diamond and netherite pieces.

Under "Protection Enchantments", enable the ones applied to your armor — each enchantment only reduces its corresponding damage type (Projectile, Fire, Blast, or Feather Falling), except Protection, which reduces all types including a portion of magic damage. The "Result" section displays final damage taken and remaining HP, while the "Armor Comparison" shows how each material set would perform in the same scenario.

Why is magic damage different?

In Minecraft Java Edition, magic damage completely ignores armor points — which is why harming potions and certain boss attacks deal heavy damage even through full armor. The Protection enchantment still mitigates a portion of magic damage, but raw armor points provide no protection against it.
