Optimize your Genshin Impact character builds by calculating the exact Energy Recharge (ER) percentage needed to guarantee your Elemental Burst is ready on every rotation.

Variables:
- Q (Burst Cost): The total energy required to cast the Elemental Burst (e.g., Raiden is 90, Zhongli is 40).
- F (Flat Energy): Energy gained through static sources that ignore ER% (e.g., Venti’s Ascension 4, Raiden’s Burst hits, Amenoma Kageuchi).
- P (Particles): The base quantity of elemental particles generated during a rotation.
- V (Multiplier): The value efficiency of particles based on character element and active/inactive field status.

What is a Genshin ER Calculator?
A Genshin ER Calculator is an essential tool for theorycrafters and casual players alike. It determines the minimum Energy Recharge percentage needed to ensure a character can cast their Elemental Burst as soon as its cooldown ends (often called “Bursting on CD”).
Without sufficient ER, your team rotation breaks, leading to massive DPS losses. However, over-investing in ER wastes sub-stats that could have gone into Crit Rate or Attack. Finding the “Golden Ratio” is key to mastering the game’s combat mechanics.
How to Calculate Genshin ER Calculator (Example)
- Identify your character’s Burst Cost (e.g., 80 for Ayaka).
- Subtract any Flat Energy (e.g., -12 from Diona’s Favonius Bow).
- Sum up all Base Particles expected in a 20-second rotation.
- Apply the Field Multiplier (usually 3x for matching element particles on-field).
- Divide the remaining cost by the particle value to get your ER decimal.
Frequently Asked Questions (FAQ)
Is 200% ER always enough? For high-cost characters like Faruzan or Raiden, 200% is often a baseline, but 250%+ might be needed in solo-element teams.
Does ER increase Flat Energy? No. Sources like Venti’s passive or Prototype Amber provide fixed energy regardless of your ER stat.
What are “Clear” particles? These come from killing enemies or reducing their HP. They provide energy to the whole team but have different scaling than skill particles.
Should I use an ER Sands? If your sub-stats cannot reach the calculated requirement, an ER Timepiece is usually the most efficient way to bridge the gap.
