Detailed Calculation Breakdown

HSR Damage Calculator Formula

AED = ATK × (M/100) × (1 - (DEF_R/100)) × (1 + (D_B/100)) × (1 + (CR/100) × (CD/100))

Source of Formula: The damage calculation used here is a simplified model of the Honkai: Star Rail damage formula, focusing on core multipliers for Expected Damage. Official Wiki Damage Formula Guide, Prydwen Damage Guide

Variables Explained

  • Base Attack (ATK): The character’s total Attack value, including Light Cone and Relics.
  • Skill Multiplier (M %): The scaling percentage of the ability used (e.g., 150% skill damage is 150).
  • Crit Rate (CR %): The chance of landing a critical hit (must be between 0 and 100).
  • Crit Damage (CD %): The bonus damage added upon landing a critical hit (180 means 180% bonus).
  • Enemy Defense Reduction (DEF_R %): Total Defense Shred/Ignore applied to the enemy.
  • Total Damage Boost (D_B %): Sum of all Elemental/Type Damage Bonuses (e.g., Lightning DMG Boost).

What is HSR Damage Calculator?

The HSR Damage Calculator is an indispensable tool for players of Honkai: Star Rail, helping to accurately estimate the destructive potential of their characters. It moves beyond simple stat comparisons by integrating all major damage components—Attack, multipliers, critical stats, and enemy resistances—into a single expected value.

By calculating the Average Expected Damage (AED), this tool provides a single, reliable metric for comparing different character builds, relic sets, and Light Cone choices. Maximizing AED is often the primary goal for DPS units in the game, making this calculation crucial for Spiral Abyss and Forgotten Hall optimization.

How to Calculate HSR Damage (Example)

  1. Input Base Stats: Enter 3000 for ATK, 250 for Skill Multiplier, 70 for CR, and 180 for CD.
  2. Input Modifiers: Enter 25 for Enemy DEF Reduction and 46 for Total Damage Boost.
  3. Calculate Crit Multiplier: The Expected Crit Multiplier is $$(1 + (0.70 \times 1.80)) = 2.26$$.
  4. Calculate Total Damage Modifiers: Combine the Defense and Damage Boost modifiers: $$(1 – 0.25) \times (1 + 0.46) = 0.75 \times 1.46 = 1.095$$.
  5. Final Damage: Multiply all components: $$3000 \times 2.5 \times 1.095 \times 2.26 = 18586.5$$.

Frequently Asked Questions (FAQ)

How important is the Crit Value (CV) in the damage formula?
The Crit Value (CV) heavily influences the Expected Damage by factoring into the final Critical Multiplier, which scales the entire damage output. It’s often the most valuable offensive stat pair.
Does this calculator account for Weakness Break damage?
No, this calculator focuses on the standard, non-Break damage of a single attack. Break damage is calculated separately based on character level and Toughness values.
Why is the result called “Average Expected Damage (AED)”?
AED accounts for your Crit Rate, meaning it is the average damage you can expect to see over many attacks (a mix of non-crit and crit hits). It is the true measure of a build’s performance.
What is the maximum achievable Defense Reduction?
While the in-game display caps Defense Reduction at certain points, the mathematical calculation can sometimes exceed 100%, though the damage increase follows complex curves not fully modeled here.
