DPS Calculator

Calculate base, effective, burst, and sustained DPS for any weapon. Factor in attack speed, critical hit chance, magazine size, and reload time. Compare two weapons side by side.

Effective DPS (no reload downtime)

Enter base damage and attack speed to see DPS results.

All DPS formulas assume uniform crit probability across attacks. Sustained DPS requires magazine size and reload time. Burst DPS equals effective DPS — it represents peak output while firing without reload interruptions.

How to use

  1. 1

    Enter weapon stats

    Type your weapon's base damage and attack speed (attacks per second) into the input fields. DPS results update live as you type.

  2. 2

    Add critical hit values

    Enter your critical hit chance (0-100%) and critical hit multiplier (e.g. 2.0x) to calculate effective DPS that factors in average crit damage.

  3. 3

    Add magazine and reload stats

    Optionally enter magazine size and reload time in seconds to calculate sustained DPS and time to empty the magazine.

  4. 4

    Compare two weapons

    Toggle compare mode to add a second weapon loadout and see both sets of DPS results side by side to determine which weapon is stronger.

Frequently asked questions

What is the difference between base DPS and effective DPS?
Base DPS is simply base damage multiplied by attack speed — it ignores crits entirely. Effective DPS factors in your critical hit chance and multiplier to give the average damage per second you'll actually deal over many attacks.
How is sustained DPS different from burst DPS?
Burst DPS is your effective DPS while actively firing — the peak damage rate with a full magazine. Sustained DPS accounts for reload downtime, giving you the true average DPS over multiple magazine cycles. In long fights, sustained DPS matters more.
What formula does the calculator use for effective DPS?
Effective DPS = Base Damage × Attack Speed × (1 + Crit Chance/100 × (Crit Multiplier − 1)). This averages out the damage boost from crits over many attacks rather than assuming you always or never crit.
What formula is used for sustained DPS?
Sustained DPS = (Magazine Size × Effective Damage Per Shot) / (Magazine Size / Attack Speed + Reload Time). It divides total magazine damage by the full cycle time including the reload, giving your real-world average output.
Why is my sustained DPS lower than burst DPS?
Sustained DPS will always be equal to or lower than burst DPS because it includes reload downtime. The longer your reload time relative to your firing time, the bigger the gap. Weapons with large magazines and fast reloads have the smallest difference.
Can I use this calculator for any game?
Yes. The formulas are universal damage-per-second math that applies to any game with attack speed, crits, and magazine mechanics — shooters, RPGs, MOBAs, ARPGs, and more. Just enter the stats from your game.

Instantly calculate damage per second for any weapon or ability loadout.

— the metrics that actually matter in prolonged engagements. Every result

card shows the formula used so you can verify the math or apply it in

spreadsheets. Toggle compare mode to place two weapon loadouts side by

side and instantly see which one wins on burst, sustained, or effective

DPS. All calculations run entirely in your browser with zero latency —
