Elden Ring Weapon Attack Rating Formula Explained

The Elden Ring weapon AR formula calculates total Attack Rating by summing base damage, upgrade bonus, and scaling contributions from each stat. Understanding this formula is essential for optimizing your Tarnished build.

Total AR = Base Damage × Upgrade Multiplier + Σ (Base Damage × Scaling Coefficient × Stat Saturation Factor) + Elemental Damage × Upgrade Multiplier

Each damage type (Physical, Magic, Fire, Lightning, Holy) is calculated separately and then summed for the total AR displayed on your equipment screen.

Stat Soft Cap Saturation

Stat contribution follows diminishing returns beyond soft caps. Below 20 yields full contribution (1.0×), 20-50 yields 0.70×, 50-80 yields 0.35×, and 80-99 yields only 0.15× effectiveness. This means pushing a stat beyond 80 provides minimal additional AR benefit.

How Elden Ring Weapon Scaling Works

Weapon scaling is the core mechanic that determines how your character's attributes translate into bonus damage. Follow this framework to understand and optimize your weapon setup:

  1. Identify scaling grades — Each weapon displays letter grades (S through E) next to STR, DEX, INT, FTH, and ARC icons on its equipment screen.
  2. Match stats to scaling — Invest your runes into the stats your weapon scales best with. A weapon with A-grade STR scaling benefits far more from Strength than from Dexterity.
  3. Apply the scaling formula — Bonus damage = base_damage × grade_coefficient × (stat / 99) × saturation_factor for each scaling stat.
  4. Consider upgrade level — Higher upgrade levels increase both base damage and the effectiveness of scaling, making upgrades the single most impactful way to boost AR.
  5. Factor in elemental damage — Weapons with split damage types apply scaling separately to each damage component, so total AR is the sum of all physical and elemental values.
  6. Compare affinities — Use different affinities (Heavy, Keen, Quality, Magic, etc.) to redistribute scaling grades and optimize for your specific stat allocation.

Elden Ring Weapon Calculation Examples

Example 1: Quality Claymore at +15 with 40 STR / 40 DEX

Base Damage: 138 Physical | Scaling: C STR, C DEX | Upgrade: +15 (1.85× multiplier)

Physical Base: 138 × 1.85 = 255
STR Bonus: 255 × 0.90 × (40/99) × 0.70 = ~65
DEX Bonus: 255 × 0.90 × (40/99) × 0.70 = ~65
Total AR: ~385 Physical

Example 2: Magic Uchigatana +20 with 20 STR / 50 DEX / 60 INT

Base: 115 Physical + 125 Magic | DEX C, INT B | +20 (2.20×)

Physical: 115 × 2.20 = 253 | DEX Bonus: 253 × 0.90 × (50/99) × 0.35 = ~40
Magic: 125 × 2.20 = 275 | INT Bonus: 275 × 1.20 × (60/99) × 0.35 = ~70
Total AR: ~638 (293 Physical + 345 Magic)

Example 3: Heavy Giant-Crusher +25 with 80 STR

Base: 165 Physical | STR S | +25 (2.50×)

Physical Base: 165 × 2.50 = 413
STR Bonus: 413 × 1.80 × (80/99) × 0.15 = ~90
Total AR: ~503 Physical (two-handed adds 50% STR bonus)

Elden Ring Affinity Comparisons for Weapon Optimization

Affinities fundamentally alter how your weapon scales with your stats. Choosing the right affinity for your build can increase total AR by 30-50% compared to a mismatched setup.

Physical Affinities

  • Standard — Balanced scaling across STR and DEX. Ideal for early-game or hybrid builds that haven't specialized yet.
  • Heavy — Maximizes Strength scaling, often upgrading to A or S grade. Best for pure Strength builds wielding large weapons.
  • Keen — Maximizes Dexterity scaling. Ideal for katanas, curved swords, and thrusting weapons on pure DEX builds.
  • Quality — Balances STR and DEX scaling at moderate grades (typically C/C or B/B). Excels when both stats are at 40-55.

Elemental Affinities

  • Magic — Adds INT scaling and splits damage into Physical + Magic. Essential for sorcerer-hybrid builds.
  • Fire — Splits into Physical + Fire damage with STR scaling. Effective against beasts and unarmored enemies.
  • Lightning — Splits into Physical + Lightning with DEX scaling. Strong against heavily armored foes and in rainy environments.
  • Holy — Splits into Physical + Holy with FTH scaling. Devastating against undead and Those Who Live in Death.
  • Occult — Adds ARC scaling for physical damage. Ideal for bleed builds using Arcane as the primary stat.
Best Affinity Rule: Match your highest stat to the affinity that grants the best scaling grade for that stat.

People Also Ask About Elden Ring Weapons

Weapon Attack Rating (AR) in Elden Ring is the sum of base damage multiplied by upgrade level plus scaling bonuses from your character stats. Each stat with a scaling grade contributes bonus damage based on the grade coefficient, your stat value divided by 99, and a saturation factor that applies soft caps at 20, 50, and 80. Physical and elemental damage types are calculated separately and then summed for the total AR.
Scaling grades range from S (best) to E (weakest) and determine the bonus damage multiplier applied to your weapon's base damage. S-grade provides approximately 1.8× the base scaling value, A-grade about 1.5×, B-grade about 1.2×, C-grade about 0.9×, D-grade about 0.6×, and E-grade about 0.35×. A weapon with no scaling letter in a stat receives zero bonus from that attribute regardless of how many points you invest.
Affinities change a weapon's scaling grade distribution and damage types. Heavy affinity boosts STR scaling (often to A or S), Keen boosts DEX scaling, Quality balances both, while Magic, Fire, Lightning, and Holy affinities add elemental damage and introduce INT, FTH, or ARC scaling. Choosing the correct affinity for your stat allocation can increase total AR by 30-50% compared to using a mismatched affinity.
Elden Ring uses diminishing returns beyond soft cap thresholds. Strength and Dexterity soft cap at 20, 55, and 80. Intelligence and Faith soft cap at 20, 50, and 80. Arcane soft caps at 20, 50, and 80 for status buildup and at 45 for item discovery. Weapon scaling follows these curves, meaning investment beyond 80 in any damage stat yields minimal additional AR benefit.
Upgrading a standard weapon from +0 to +25 increases base damage by approximately 2.5× to 3×. Somber weapons upgraded from +0 to +10 also reach roughly 2.5× to 3× base damage. Each upgrade increment provides a small percentage increase, with larger jumps at milestone levels. Higher upgrade levels also amplify scaling bonus calculations since scaling applies to the upgraded base damage value.

Frequently Asked Elden Ring Weapon Questions

Yes. The calculator computes physical damage plus one optional elemental damage type (Magic, Fire, Lightning, or Holy). Each damage component applies its own scaling calculations based on the relevant stat grades, then all values are summed for the total Attack Rating displayed on your equipment screen.
Two-handing a weapon in Elden Ring provides a 1.5× multiplier to your effective Strength stat for damage calculation purposes. While this calculator computes one-handed AR by default, you can simulate two-handing by multiplying your Strength stat by 1.5 before entering it. This is especially impactful on Heavy-infused weapons with high STR scaling.
In-game AR can vary by 1-5 points due to rounding mechanics and hidden decimal precision in Elden Ring's engine. The calculator uses community-derived scaling coefficients that closely approximate in-game values. For exact min-max planning, treat calculator results as accurate within a small margin of error.
Absolutely. Adjust the scaling grade selections to match different affinities and recalculate. For example, switch STR from C to A and DEX from C to E to simulate Heavy affinity, or set both to B for Quality. This allows direct AR comparisons between any affinity setup for your current stat allocation.
This calculator focuses on Attack Rating (direct damage) rather than status effect buildup. Bleed, Frost, Poison, Scarlet Rot, and Madness buildup scale primarily with Arcane and follow different formulas. Use this tool for raw damage optimization and consult specialized status calculators for buildup comparisons.
Yes. Many players use the weapon AR calculator to determine raw Attack Rating and then use the Elden Ring Damage Calculator to factor in enemy defenses, negation, and motion values for specific attacks. Combining both tools provides the most complete picture of your actual damage output in combat.

Elden Ring Weapon Glossary

Attack Rating (AR)

The total damage value displayed on a weapon's equipment screen, representing the sum of all physical and elemental damage before enemy defenses are applied.

Scaling Grade

A letter rating (S, A, B, C, D, E) indicating how effectively a weapon converts a specific stat into bonus damage. S is strongest, E is weakest.

Soft Cap

A stat threshold beyond which additional investment yields diminishing returns. Most damage stats soft cap at 20, 50, and 80 in Elden Ring.

Affinity

A weapon modification that changes scaling grade distribution and damage types. Examples include Heavy (STR), Keen (DEX), Magic (INT), and Holy (FTH).

Upgrade Multiplier

The factor by which base damage increases at each upgrade tier. Standard weapons reach ~2.5× at +25; Somber weapons reach ~2.5× at +10.

Split Damage

Weapons that deal multiple damage types (e.g., Physical + Magic). Each type passes through enemy defenses separately, which can reduce effective damage.

Two-Handing Bonus

Wielding a weapon with both hands multiplies effective Strength by 1.5× for damage calculation and meeting minimum requirements.

Motion Value

A hidden multiplier tied to specific attack animations that determines what percentage of AR is applied on each hit. Varies by weapon class and move type.
