How Damage Calculations Work in Games

Most games calculate outgoing damage using a base value modified by a sequence of multipliers: base stat, weapon damage, flat bonuses, percentage bonuses, critical hit modifier, and finally reduced by the target's defense or resistance. Understanding the order of operations lets you optimise your build effectively.

Critical Hits Explained

A critical hit multiplier of 150% means crits deal 1.5× your normal (post-bonus, post-resistance) damage. Most games express crit multiplier as a percentage above base (so 150% = 50% extra), while some express it as the total multiplier (1.5×). Check your game's documentation to confirm which system is used.

Average DPS With Crit Chance

Average DPS accounts for the fact that not every hit crits. With a 25% crit chance and 150% crit multiplier, your average hit is: (0.75 × normal) + (0.25 × crit) = (0.75 × 1) + (0.25 × 1.5) = 1.125× normal — a 12.5% DPS increase from crits alone. This calculator shows that average for you.

Resistance and Flat Reduction

Resistance is typically a percentage reduction applied after all offensive multipliers. A 20% resistance means the target takes 80% of your calculated damage. Some games use flat armor values with a formula instead — this tool models the simpler percentage-based resistance common in many RPGs and action games.
