What damage formula does this use?

It follows Genshin Impact's outgoing-damage model: base talent damage times the total damage multiplier, then a DEF-reduction factor, then a resistance multiplier, then the crit-weighted average. Each stage matches how the game actually applies modifiers.

How is the crit-weighted average calculated?

Average damage equals non-crit damage times one plus CRIT rate times CRIT damage. With 60 percent CRIT rate and 120 percent CRIT damage the multiplier is 1 + 0.6 times 1.2 = 1.72. CRIT rate above 100 percent is capped at 100 percent.

How does enemy defense reduce my damage?

The DEF multiplier is (your level + 100) divided by ((your level + 100) + (1 minus DEF reduction) times (enemy level + 100)). Higher enemy level means a smaller multiplier, which is why DEF shred and level matter.

How does resistance work?

If enemy resistance is between 0 and 75 percent, the multiplier is 1 minus resistance. Negative resistance uses 1 minus half the negative value. Resistance at or above 75 percent uses 1 divided by (4 times resistance + 1).

Is this exact for every character?

It captures the core multiplicative chain that drives most hits. Reaction damage, amplifying reactions, and infusion add separate multipliers you can fold into the damage-bonus field. Use it to compare builds, not as a frame-perfect simulator.

Genshin Impact damage is a chain of multipliers, not a single number. This calculator applies the game’s real outgoing-damage formula — talent base, total damage bonus, defense reduction, resistance, and a crit-weighted average — then divides by your attack interval to give a comparable DPS figure.

How it works

The per-hit and DPS calculation follows the in-game order of operations:

nonCrit  = baseDmg × abilityMult% × (1 + dmgBonus%)
defMult  = (lvl + 100) / ((lvl + 100) + (1 − defReduction) × (enemyLvl + 100))
resMult  = res ≥ 0.75 ? 1 / (4·res + 1) : res < 0 ? 1 − res/2 : 1 − res
avgHit   = nonCrit × defMult × resMult × (1 + min(crit,1) × critDmg)
DPS      = avgHit / hitInterval

Capping CRIT rate at 100 percent and applying the piecewise resistance rule are both true to the game and matter for high-investment builds.

Example and tips

A hit with 400 base damage, a 250 percent ability multiplier, 80 percent damage bonus, 65 percent CRIT rate and 130 percent CRIT damage against an equal-level enemy with 10 percent resistance lands for roughly 1,600 average damage. Lower the enemy resistance with shred effects and you will see the resistance multiplier climb, which is often a bigger gain than stacking more ATK percent.
