Comparing two Path of Exile builds by eye is misleading because the game treats two kinds of damage bonus completely differently. This calculator applies the real formula so you can see your true damage per second and judge whether a gear or passive change is actually an upgrade.
How it works
The damage model follows Path of Exile’s actual order of operations:
hitDamage = baseHit * (1 + increased/100) * (1 + more/100)
averageHit = hitDamage * (1 + critChance * (critMulti - 1))
DPS = averageHit * attacksPerSecond
All of your increased modifiers are summed into one additive bonus, while the
more multiplier compounds on top. That single distinction is why a more
source is usually worth far more than the same number printed as increased.
Crit and attack speed
Critical strikes multiply your hit by the crit multiplier whenever they land. Averaged over many hits, your effective damage rises by `critChance * (critMulti
- 1)`. Multiplying the average hit by your attacks or casts per second turns a single-hit number into sustained DPS.
Example
A 400 base hit with +180% increased, +40% more, 35% crit at 150% multi and
1.8 APS yields a modified hit of 400 * 2.8 * 1.4 = 1568, an average hit of
about 1843 after crit, and roughly 3317 DPS. Swap the +40% more for
+40% increased instead and DPS drops noticeably — proof of why more wins.
