What is the Game Damage Calculator?
Calculate normal damage, critical hit damage, and expected average damage per hit for RPG, action, and similar games. Enter your character's attack power, crit rate, crit damage multiplier, and defense penetration to find the optimal stat build. Compare different combinations to maximize your DPS output.
Formulas
- Effective Defense = max(0, Enemy Defense − Penetration)
- Normal Damage = Attack × (1 − Effective Defense / 100)
- Critical Damage = Attack × (Crit DMG% / 100) × Defense Multiplier
- Average Damage = Normal × (1 − Crit Rate) + Crit × Crit Rate
Frequently Asked Questions
Your critical hits deal 2× your base damage. Check your game's description, as some games define crit damage as the bonus above normal (e.g., 100% bonus = 2× total).
Effective defense becomes 0%, ignoring the enemy's defense entirely. Extra penetration beyond their defense has no additional benefit.
When crit rate is low, increasing it provides more value. At high crit rates, boosting crit damage or base attack often yields better returns. Use this calculator to compare options.
