DPS / Damage Calculator

Calculate DPS from min/max hit, attack speed, crit chance and crit multiplier, plus average hit, effective hit and time to kill.

About this tool

The DPS / Damage Calculator turns a weapon's stats into damage per second and time to kill, the numbers behind every RPG or shooter build comparison. It all runs in your browser with nothing uploaded. Enter the minimum and maximum hit (set them equal for a flat average), attacks per second, critical chance and multiplier, hit chance, and optionally the target's health.

It starts from the average hit (min + max) / 2, then applies a critical factor of 1 + (crit% / 100)·(critMult − 1), which is the long-run damage boost from criticals. Damage per second is avgHit · attacksPerSec · critFactor · (hitChance / 100), folding in how often you actually connect. If you supply target HP, the time to kill is simply HP / DPS.

The effective hit tile shows your average damage per landed blow including criticals, and the max-crit tile shows the biggest single number you can roll (max × multiplier). Because the crit factor is an average, DPS represents sustained output over many swings rather than any one hit — useful for comparing weapons, not for predicting a specific attack.

Frequently asked questions

How is the crit factor worked out?
critFactor = 1 + (crit chance / 100)·(crit multiplier − 1). At 25% chance and a 2× multiplier that is 1 + 0.25·1 = 1.25, meaning criticals raise your average damage by 25% over the long run.
What if my weapon has a fixed damage, not a range?
Enter the same number in both the minimum and maximum fields. The average hit becomes that value and every other figure follows from it exactly.
How is time to kill calculated?
Time to kill = target HP ÷ DPS, the sustained-damage estimate. It assumes your average output including crit and hit chance; a run of bad luck or a burst of criticals will make a real fight shorter or longer.
Does hit chance affect DPS?
Yes. DPS is multiplied by hit chance / 100, so a 90% hit chance scales your damage to 90% of its perfect-accuracy value. Set it to 100 if your attacks always land.
