Genshin Er Calculator

Determine the optimal Energy Recharge for your burst rotations

What is a Genshin ER Calculator?

A Genshin ER Calculator is an essential tool for players looking to optimize their character rotations. In Genshin Impact, Energy Recharge (ER) determines how quickly a character can regain their Elemental Burst. Using a Genshin ER Calculator helps you avoid “dead rotations” where your characters are waiting for energy, thus significantly increasing your team’s total DPS (Damage Per Second).

Every character has a unique energy requirement and particle generation rate. Without a Genshin ER Calculator, most players either build too much ER (wasting potential damage stats like Crit or ATK) or too little (breaking their rotation). This tool calculates the exact percentage needed based on your team composition and weapon choices.

Genshin ER Calculator Formula and Mathematical Explanation

The math behind energy gain is complex because it factors in particle type, character element, and whether the character is on or off the field. The Genshin ER Calculator uses the following core logic:

Required ER% = [(Burst Cost – Flat Energy) / (Raw Energy from Particles)] * 100

Variable	Meaning	Base Value	Range
Burst Cost	Energy required for Elemental Burst	40-90	Fixed per character
Flat Energy	Direct energy gain (no ER scaling)	0-20	Varies by weapon/passive
Same Element Particle	Energy from matching element	3.0	On-field (100%)
Diff Element Particle	Energy from non-matching element	1.0	On-field (100%)
Off-field Multiplier	Reduction for inactive characters	0.6	Fixed for 4-man party

Practical Examples

Example 1: Ayaka in a Freeze Team
Ayaka has an 80-cost burst. She generates 4-5 particles. If Diona (Same Element) generates 4 particles with Sacrificial Bow, the Genshin ER Calculator would factor in those 9 cryo particles. With some neutral particles from enemies, Ayaka usually needs around 140% ER to burst on cooldown.

Example 2: Bennett as a Solo Pyro
Bennett needs 60 energy. If he is the only Pyro on the team and spends most time off-field, he only gets 0.6 energy per different-element particle. The Genshin ER Calculator would show he needs significantly more ER—often 200% or higher—to ensure his field is always ready.

How to Use This Genshin ER Calculator

• Step 1: Select your character’s Burst Cost from the dropdown menu.
• Step 2: Input the average number of particles your character generates with their Skill.
• Step 3: Add particles generated by your teammates. Matching elements give significantly more energy.
• Step 4: Include “Flat Energy” sources like Favonius weapon procs (approx 6 energy) or specific character passives.
• Step 5: Toggle between On-Field or Off-Field depending on your character’s role.
• Step 6: Review the Genshin ER Calculator result and adjust your artifact sub-stats accordingly.

Key Factors That Affect Genshin ER Calculator Results

1. Team Composition: Running a “Battery” (a character of the same element) drastically reduces the result of the Genshin ER Calculator.

2. Favonius Weapons: These generate neutral particles that benefit the entire team, making them the single best way to lower teamwide ER needs.

3. Rotation Length: Longer rotations allow for more Skill uses, providing more particles and lowering the ER requirement per second.

4. Enemy Particle Drops: High-HP enemies drop particles at certain thresholds. The Genshin ER Calculator assumes a baseline, but “boss fights” usually provide fewer particles.

5. Artifact Sets: Sets like Emblem of Severed Fate provide a flat 20% ER, which is the first building block in your Genshin ER Calculator settings.

6. Ping and Execution: If you swap characters too slowly, they might catch particles off-field, reducing energy gain and requiring a higher ER buffer.

Frequently Asked Questions (FAQ)

Why is my ER higher than what the Genshin ER Calculator suggests?

You might be missing particle catches or your teammates are not generating as many particles as estimated. Always add a 10% safety buffer.

Does ER affect flat energy gain?

No. Flat energy from sources like Raiden’s Burst or Amenoma Kageuchi does not scale with ER. The Genshin ER Calculator subtracts these from the cost first.

What is the “Soft Cap” for ER?

While there is no hard cap, building over 250% ER (except for Raiden or Mona) usually results in a significant loss of offensive stats.

Is 100% ER enough for anyone?

Only for characters who don’t rely on their burst or those paired with extreme batteries in very specific Genshin ER Calculator scenarios.

How do Neutral Particles work?

Neutral particles (white) give 2 energy to the active character and 1.2 to off-field characters regardless of element.

Does the number of enemies matter?

Yes. More enemies mean more HP-threshold particles, which the Genshin ER Calculator often averages out.

Should I use an ER Sands?

If your Genshin ER Calculator result is above 160-170% and you don’t have an ER weapon, an ER Sands is usually necessary.

What is a “Battery” in Genshin?

A character who generates a high volume of particles to feed another character, effectively lowering their Genshin ER Calculator requirement.
