Understanding the Genshin Crit Rate Calculator
Optimizing character damage in Genshin Impact involves balancing three main stats: Attack, Critical Rate (CR), and Critical Damage (CD). Many players make the mistake of stacking purely Critical Damage while neglecting Critical Rate, resulting in big numbers that appear rarely, leading to lower overall damage over time (DPS).
This calculator helps you determine your Average Damage, which is the mathematical expectation of your damage output over a long fight. It considers how often you crit and how hard you hit when you do.
The Golden Ratio: 1:2
In the Genshin Impact theorycrafting community, the "Golden Ratio" for stats is widely considered to be 1:2. This means for every 1% of Crit Rate, you should ideally have 2% of Crit Damage.
- Example: If you have 50% Crit Rate, you should aim for 100% Crit Damage.
- Example: If you have 70% Crit Rate, you should aim for 140% Crit Damage.
Once your Crit Rate reaches 100%, any additional Crit Rate is wasted stat value, and you should focus entirely on Attack or Crit Damage. Until you hit that cap, maintaining the 1:2 balance generally yields the highest mathematical Average Damage for the stats invested.
Formulas Used in This Calculator
Understanding the math behind your artifacts can help you make better gear decisions.
1. Average Damage
This is the most important metric for DPS consistency.
Average DMG = Total ATK × (1 + (Crit Rate% × Crit Damage%))
Note: If Crit Rate is above 100%, it is capped at 100% (or 1.0) for this calculation.
2. Critical Hit Damage
The damage number you see on screen when you land a crit (big font).
Crit Hit = Total ATK × (1 + Crit Damage%)
3. Artifact Crit Value (CV)
While not calculated in the total damage formula above, "CV" is often used to judge individual artifacts. The formula for CV is:
CV = (Crit Rate × 2) + Crit Damage
Generally, an artifact with 20+ CV is decent, 30+ is good, and 40+ is excellent ("unicorn" tier).
How to Use This Tool
- Total Attack: Open your character attribute screen details and input the white number + green number sum (the final ATK value).
- Crit Rate: Input your total Crit Rate percentage.
- Crit Damage: Input your total Crit Damage percentage.
- Analyze: Click calculate to see if your build is efficient. If the tool suggests your ratio is skewed, consider swapping your Circlet (Headpiece) artifact between CR and CD main stats to balance the build.
