DPS Calculator

GamingDamage and Combat Stats

Average non-critical damage of one hit, after the target's armour if you know it.

Hits per second. For a 0.8 s swing timer, enter 1 ÷ 0.8 = 1.25.

A crit that deals 150% damage is 1.5×; +100% crit damage is 2×.

Optional: adds a time-to-kill estimate.

How much of your DPS comes from crits
The chart appears with your result

Expected DPS is damage per hit times attacks per second times (1 + crit chance × (crit multiplier − 1)). A weapon hitting for 100 at 1.5 hits per second with a 25% chance of a 2× crit averages 125 per hit, so it deals 187.5 damage per second instead of 150 without crits.

About this tool

Players comparing two weapons, deciding between attack speed and crit stats, or checking whether a build can clear a boss before an enrage timer all need the same number: sustained damage per second. Enter the damage of a normal hit, how many hits land each second, and your crit chance and crit multiplier. The calculator returns expected DPS, the average hit with crits folded in, the DPS you would have without crits, how much crits add in percent, damage per minute and, if you give a target's health, the time to kill. A donut chart splits your DPS into normal damage and crit bonus. The result is a long-run average: it ignores cooldowns, damage over time, armour that changes per hit and the streakiness of random crits over a short fight.

How to use it

  1. Enter hit damage and speed

    Type the damage of one normal hit and the attacks per second. Convert a swing timer by dividing 1 by the seconds per swing.

  2. Set crit chance

    Drag the slider or type the exact percentage from your character sheet.

  3. Enter the crit multiplier

    Use the total multiplier on a crit: 150% damage is 1.5, a +100% bonus is 2.

  4. Add target health

    Optionally enter the enemy's health to see how many seconds the fight takes at this DPS.

Examples

100 damage, 1.5 hits/s, 25% crit at 2×

Damage per hit
100
Attack speed
1.5
Crit chance
25
Crit damage multiplier
2

Result Expected DPS: 187.5
Average hit (crits included): 125
DPS without crits: 150
Damage of one crit: 200
DPS added by crits: 25%
Damage per minute: 11,250
Time to kill: No target set

  1. Base DPS = 100 × 1.5 = 150
  2. Average hit = 100 × (1 + 0.25 × (2 − 1)) = 125
  3. Expected DPS = 125 × 1.5 = 187.5

One hit in four doubles, so the average hit is 125 and crits lift DPS from 150 to 187.5, a 25% gain.

50 damage, 2 hits/s, 1,000 HP target

Damage per hit
50
Attack speed
2
Crit chance
0
Crit damage multiplier
2
Target health
1000

Result Expected DPS: 100
Average hit (crits included): 50
DPS without crits: 100
Damage of one crit: 100
DPS added by crits: 0%
Damage per minute: 6,000
Time to kill: 10 s

  1. Base DPS = 50 × 2 = 100
  2. Average hit = 50 × (1 + 0 × (2 − 1)) = 50
  3. Expected DPS = 50 × 2 = 100
  4. Time to kill = 1000 ÷ 100 = 10 s

With no crit chance DPS is plain damage times rate, 100, so a 1,000 HP target falls in 10 seconds.

200 damage, 0.8 hits/s, 50% crit at 2.5×

Damage per hit
200
Attack speed
0.8
Crit chance
50
Crit damage multiplier
2.5

Result Expected DPS: 280
Average hit (crits included): 350
DPS without crits: 160
Damage of one crit: 500
DPS added by crits: 75%
Damage per minute: 16,800
Time to kill: No target set

  1. Base DPS = 200 × 0.8 = 160
  2. Average hit = 200 × (1 + 0.5 × (2.5 − 1)) = 350
  3. Expected DPS = 350 × 0.8 = 280

Half the hits deal 500, so the average hit is 350 and DPS is 350 × 0.8 = 280.

How it is calculated

DPS = D × S × (1 + c × (M − 1))

D
damage of one non-critical hit
S
attacks per second
c
crit chance as a fraction (25% = 0.25)
M
crit damage multiplier

Each hit is either normal, with probability 1 − c, or critical, with probability c. Its expected damage is (1 − c)·D + c·M·D, which simplifies to D × (1 + c(M − 1)). Multiplying by hits per second gives expected DPS. The term c(M − 1) is the fraction crits add, so 25% at 2× adds 25% and 50% at 2.5× adds 75%. Time to kill is target health divided by expected DPS.

When not to use it

  • Skill rotations with cooldowns and cast times need a full rotation simulation.
  • Damage-over-time effects and procs are not modelled unless you fold them into hit damage.
  • Short fights of a few hits can land far above or below the average because crits are random.

Common mistakes

  • Entering crit damage as a bonus (100) instead of the total multiplier (2).
  • Typing the swing interval where attacks per second is asked for.
  • Taking tooltip damage before enemy armour or resistance reduces it.
  • Counting crit chance above 100%, which most games cap.

Frequently asked questions

Is attack speed or crit chance worth more?

Compare the percentage each adds. Raising attack speed by 10% raises DPS by exactly 10%. Raising crit chance by 10 points adds 10 × (M − 1) percent of base damage, so at a 2× multiplier it also adds 10% of base DPS, and at 2.5× it adds 15%. Enter both options here and compare the expected DPS.

What does a crit multiplier of 1.5 mean?

A critical hit deals 1.5 times normal damage, so a 100-damage hit crits for 150. Games that list crit damage as +50% mean the same thing. If a game shows crit damage as 150%, that is also 1.5×.

Why is my in-game DPS meter different?

Meters record real hits over a real fight, including misses, armour, buffs, procs, damage over time and pauses for movement. Over a short fight, random crits also push the measured number away from the average. This calculator gives the long-run expected value for steady hitting.

How do I convert a weapon's attack interval to attacks per second?

Divide 1 by the interval. A weapon that swings every 2.6 seconds makes 1 ÷ 2.6 = 0.385 attacks per second; a 0.5 second interval is 2 attacks per second.

How is time to kill worked out?

Target health divided by expected DPS. A 5,000 HP target against 187.5 DPS lasts about 26.7 seconds. It assumes every hit lands and the target does not heal or gain shields during the fight.

Does 100% crit chance just multiply DPS by the crit multiplier?

Yes. With c = 1 every hit is a crit, so the formula reduces to D × S × M. At that point extra crit chance does nothing and only crit damage, hit damage or attack speed raise DPS.
