Damage Per Second
Calculator

Base DPS is damage per hit multiplied by attacks per second (or divided by the time between attacks); for weapons with variable damage, average damage per hit is used, and for hit-chance-dependent attacks, that probability is factored in as well.

DPS depends on the product of damage and attack speed, not either alone — a weapon that hits twice as hard but half as often has identical DPS to one that hits half as hard twice as often, so raw hit damage alone doesn't tell you which weapon is stronger.

A full DPS calculation should blend critical and non-critical damage by their probability of occurring — average damage per hit becomes (crit chance × crit damage) + (non-crit chance × base damage) — rather than using either base or critical damage alone, which would misrepresent actual output.

DoT effects add their own damage-per-second contribution on top of direct-hit DPS, calculated as the DoT's total damage divided by its duration; sustained DPS in a real fight should sum direct damage and any active DoT effects together.

In-game meters measure real combat, which includes missed attacks, target movement, downtime reloading or repositioning, and buffs or debuffs that change over the fight, while a theoretical DPS calculation usually assumes ideal, uninterrupted conditions.
