DPS Calculator
Calculate damage per second with attack speed and critical hits.
About this calculator
This calculator turns four common weapon/build stats into a single damage-per-second figure. Basic DPS is the simplest baseline: Base Damage multiplied by Attack Speed, ignoring critical hits entirely. Effective DPS then layers critical hits on top by computing an "effective multiplier" -- 1 plus your Crit Chance (as a fraction) times (Crit Multiplier minus 1) -- and applying it to Basic DPS. That formula works because a hit either lands as a normal hit (contributing its full damage) or as a crit (contributing Crit Multiplier times as much), so the expected value per hit averages out to base damage times this blended multiplier.
Avg Damage / Hit applies that same multiplier directly to Base Damage rather than to the DPS figure, giving you the expected damage of a single swing before attack speed is factored in. Burst Damage (5s) is simply Effective DPS times five, a quick estimate of total damage output over a short burst window often used to compare cooldown-heavy builds. TTK (10K HP target) divides a fixed 10,000 hit-point pool by Effective DPS to estimate how many seconds it would take to defeat a target with that health total -- useful for comparing builds head to head against a common benchmark, though it assumes constant, uninterrupted damage output with no misses, resistances, or defensive mitigation on the target's side.

How to Use This Calculator
- Enter your character's Base Damage per hit and Attack Speed in attacks per second.
- Enter Crit Chance as a percentage and Crit Multiplier (e.g., 2× for double damage on crits).
- Review Effective DPS accounting for critical hit probability versus Basic DPS without crits.
- Check Average Damage Per Hit and Burst Damage over 5 seconds for short combat encounters.
- Use Time to Kill (TTK) against a 10,000 HP target to compare weapon or build efficiency.

Frequently Asked Questions
Why is Effective DPS higher than Basic DPS?
Effective DPS multiplies Basic DPS by an effective-multiplier factor of 1 plus Crit Chance times (Crit Multiplier minus 1). As long as Crit Multiplier is above 1 (any crit deals more than a normal hit) and Crit Chance is above zero, that factor is always greater than 1, so Effective DPS is always at or above Basic DPS -- the two are only equal when Crit Chance is 0% or Crit Multiplier is exactly 1x.
How does raising Crit Multiplier change TTK?
Raising Crit Multiplier raises Effective DPS (since crits now deal more damage per hit), and TTK (10K HP target) is 10,000 divided by Effective DPS, so a higher Effective DPS always produces a lower or equal TTK. In other words, a bigger crit multiplier shortens the estimated time to defeat a 10,000 HP target, all else held equal.
What's the difference between Avg Damage / Hit and Basic DPS?
Avg Damage / Hit applies the crit-adjusted effective multiplier to Base Damage alone, giving the expected damage of a single attack. Basic DPS instead multiplies raw Base Damage by Attack Speed with no crit adjustment at all -- so Avg Damage / Hit answers "how much does one swing do on average," while Basic DPS answers "how much damage per second with crits ignored entirely."
Does Attack Speed affect Avg Damage / Hit?
No. Avg Damage / Hit only depends on Base Damage, Crit Chance, and Crit Multiplier -- it represents the expected damage of a single hit and has no time dimension. Attack Speed only enters the calculation for the per-second figures (Basic DPS, Effective DPS, and everything derived from them), since it converts a per-hit damage value into a per-second rate.
Why does TTK (10K HP target) use a fixed 10,000 HP figure?
TTK is meant as a comparison benchmark between different weapon or build configurations rather than a prediction for a specific in-game enemy, so it uses a round, fixed target health pool rather than asking you to enter one. If your actual target has a different HP total, scale TTK proportionally: doubling the target's HP roughly doubles the time to kill for the same Effective DPS.
