Path of Exile (PoE) is a complex Action RPG known for its deep character customization and challenging combat. A key metric for assessing your character's effectiveness is Damage Per Second (DPS). Understanding and calculating your DPS allows you to optimize your build, gear, and skills to defeat tougher enemies and bosses more efficiently.
DPS is not a single, simple calculation in Path of Exile. It's influenced by a multitude of factors, including your weapon's base damage, your attack speed, your chances to land critical strikes, and various damage multipliers. This calculator provides a simplified estimation of your potential DPS, focusing on common offensive mechanics.
Key Components of DPS Calculation:
Base Damage: The fundamental damage value of your primary skill or attack. This is often derived from your weapon's damage range or a skill's inherent damage.
Attack Speed: How many times per second your character can perform an attack or cast a spell. Higher attack speed directly translates to more damage instances over time.
Critical Strike Chance: The probability that an attack will be a critical strike, dealing significantly more damage.
Critical Strike Multiplier: The percentage by which a critical strike's damage is increased beyond its normal value. A 100% multiplier means double damage; a 200% multiplier means triple damage.
Added Damage: Flat damage values (minimum and maximum) that are added to your base damage on each hit. This can come from gear, jewels, or skill modifications.
Damage Over Time (DoT) Multipliers: For skills that apply damage over time effects (like poison, bleed, or burning), these multipliers increase the damage of that effect.
Hit to DoT Conversion: Some mechanics allow a portion of your hit damage to be converted into damage over time.
This calculator aims to give you a foundational understanding of how these elements interact. For a truly exhaustive calculation, you would need to account for numerous other modifiers such as elemental resistances, penetration, specific skill gems, support gems, passive tree nodes, and much more. However, this tool serves as an excellent starting point for comparing different gear pieces or skill setups and understanding their impact on your offensive power.
Example Calculation:
Let's say you have a character with the following stats:
Base Damage: 150
Attack Speed: 3.0 attacks per second
Critical Strike Chance: 40%
Critical Strike Multiplier: 450%
Added Damage (Min): 20
Added Damage (Max): 35
Damage Over Time Multiplier: 100%
Hit to DoT Conversion: 0%
The average hit damage would be calculated considering base damage, added damage, and critical strike chance. The overall DPS then multiplies this average hit damage by attack speed, critical strike multipliers, and any DoT conversions.

var averageHitDamage = (averageNonCritDamage * (1 – criticalStrikeChance)) + (averageCritDamage * criticalStrikeChance);
// Calculate DPS from hits
var hitDPS = averageHitDamage * attackSpeed;

// In reality, DoT duration and application are more complex. This is a simplified representation.
var averageDoT damagePerHit = averageNonCritDamage * hitToDotConversion; // Damage that converts to DoT

// Total DPS is a combination of hit damage and DoT damage.
// For a general DPS calculator, we often sum them. However, in PoE, it's common to
// report Hit DPS and DoT DPS separately if they are from different sources or mechanics.
// For simplicity here, we'll calculate a combined DPS if DoT conversion is present,
// otherwise, it's just hit DPS.
var totalDPS = hitDPS;
