How to Calculate Pathfinder 2e Damage Per Round (DPR)

DPR = (Hit Chance × Avg Damage per Hit) × Number of Attacks per Round.

In Pathfinder 2e, your attack bonus against a target's AC determines your hit chance. A d20 roll needs to meet or exceed (AC - Attack Bonus). The formula for hit chance is:

Hit Chance = max(0, min(100, (21 - (AC - Attack Bonus)) / 20) × 100)

Critical hits on a natural 20 deal double damage dice. Critical fumbles on a natural 1 always miss.

Use this calculator to compare builds, optimize your action economy, and plan your combat strategy for your Pathfinder 2nd Edition game. Whether you're a weapon-focused fighter or a spell-slinging wizard, understanding your average DPR helps you make informed tactical decisions at the table.
