What formula is used?

Average Damage = Base Damage × (1 + Crit Chance × (Crit Multiplier − 1)). For example, 100 base, 50% crit chance, 200% crit multiplier gives 100 × (1 + 0.5 × 1) = 150 average damage.

What does crit multiplier of 200% mean?

It means crits deal 200% of base damage (2× base). Some games express it as "bonus crit damage" — in that case, add 100% to get the total multiplier before entering it here.

How is DPS calculated?

DPS = Average Damage × Attacks Per Second. If you leave APS blank, only per-hit stats are shown.

Which is better: more crit chance or more crit damage?

It depends on your current values. The marginal gain from crit chance decreases as it approaches 100%. Use the Sensitivity panel in the calculator to compare the per-unit gain of each stat at your current values.

Does this work for games with additive vs multiplicative crit?

This calculator uses the standard multiplicative crit formula. Some games (e.g. those with additive damage bonuses stacked before the crit multiply) may differ slightly, but the core formula applies to most ARPGs and action games.
