PoE2 DPS Calculation Formula

Step 1: Calculate Effective Critical Multiplier (ECM)

$$ECM = 1 + (\frac{CSC}{100} \times (\frac{CM}{100} – 1))$$

Step 2: Calculate Average Hit Damage (AHD)

$$AHD = BaseDamage \times (1 + \frac{IncreasedMods}{100}) \times \frac{DamageEffectiveness}{100} \times ECM$$

Step 3: Calculate Final DPS

$$DPS = AHD \times AttackSpeed$$

Variables Explained

  • Base Hit Damage: The flat, unscaled damage number from your weapon or skill.
  • Attack/Cast Speed: The number of times your character can hit or cast a skill per second.
  • Critical Strike Chance: Your percentage chance (0 to 100) to land a critical hit.
  • Critical Multiplier: The total damage multiplier applied on a critical hit (e.g., 150 means 150% of base damage, or 50% extra).
  • Skill Damage Effectiveness: A unique skill modifier determining how much of your base damage applies to the skill.
  • Total “Increased” Damage Modifiers: The sum of all generic “Increased Damage” percentages from passive trees, gear, etc. (e.g., 200 for +200%).

What is PoE2 DPS Calculation?

Damage Per Second (DPS) is the most important metric for evaluating the offensive power of any character build in Path of Exile 2. Unlike simple attack damage, DPS takes into account the rate at which you deal damage (speed) and the statistical chance and magnitude of your critical strikes (multipliers).

The calculation is based on several layers of multiplicative and additive scaling. Base damage is first modified by additive “Increased” sources, then scaled by the skill’s effectiveness, and finally amplified by the average critical strike chance. Understanding this hierarchy is crucial for optimizing your passive tree and gear choices, ensuring you invest in the stats that provide the greatest overall return on damage.

How to Calculate PoE2 DPS (Example)

  1. Gather Variables: Start with Base Damage (500), Attack Speed (2.5), Crit Chance (60%), Crit Multiplier (200%), Effectiveness (100%), and Increased Mods (200%).
  2. Calculate Effective Critical Multiplier (ECM): The critical multiplier is 2.0. The extra damage is 1.0 (2.0 – 1). With a 60% chance, the ECM is $1 + (0.6 \times 1) = 1.6$.
  3. Calculate Increased Damage: 200% increased damage means a $1 + 2.0 = 3.0$ multiplier on the base damage.
  4. Calculate Average Hit Damage (AHD): $500 \times 3.0 \times 1.0 \times 1.6 = 2400$ Damage per Hit.
  5. Calculate Final DPS: $2400 \times 2.5$ Attacks per Second $= 6,000$ DPS.

Frequently Asked Questions (FAQ)

Q: Why is “Increased Damage” additive and “Critical Multiplier” multiplicative?

A: In ARPGs like PoE2, all sources of “Increased Damage” are added together before being applied to the base damage. This is an additive layer. Critical Strike Multipliers, however, act as a final, separate multiplier, which is why they offer massive scaling potential.

Q: What is the most important stat for scaling DPS?

A: It depends on your current build. Generally, focusing on the weakest layer provides the largest immediate gain. If your Crit Chance is low, scaling that helps the most. If your total “Increased Damage” is already 500%, seeking a “More Damage” or Critical Multiplier source will yield better results.

Q: Does the calculator include elemental damage conversion?

A: For simplicity, this calculator assumes all damage is of one type. In a real build, damage conversion and resistance penetration would need to be factored in separately after the AHD calculation.

Q: Can I use the calculator for Cast Speed instead of Attack Speed?

A: Yes. The “Attack/Cast Speed” field represents the rate of skill activation per second. The math remains the same whether the skill is an attack or a spell cast.
