🐉 Encounter Difficulty Calculator
Enter your party’s level and size, the number of monsters, and their total XP value to estimate how difficult the encounter will be.
What this calculator does
This calculator applies the classic tabletop RPG encounter-building method to estimate how tough a fight will feel for a given party, based on character level, party size, and the monsters involved.
How the calculation works
Each character level has published XP thresholds for Easy, Medium, Hard, and Deadly encounters; multiplying the per-character threshold by party size gives the party’s threshold. The monsters’ combined base XP is then scaled up by a multiplier that increases with the number of monsters, since fighting several enemies at once is harder than the raw XP total suggests. Comparing the adjusted XP to the four thresholds gives the difficulty band.
This is a simplified version of the standard multiplier table (it doesn’t shift multiplier tiers for very small or very large parties) and is meant as a general planning guide, not a strict rule.
