Formula and variables

B = T(L, tier) × n; X = XP × c; classify X against Low, Moderate and High thresholds

L: party level
n: party size
XP: XP per monster
c: number of monsters
B: party XP budget
T: 2024 XP threshold by level and tier

2024 budgets: B = T(level, tier)×party size; total monster XP = XP per monster×count, without a count multiplier. Compare with Low, Moderate and High thresholds.

Frequently asked questions

How does the 2024 encounter estimate work?

It adds monster XP without a monster-count multiplier and compares the total with the party-size-adjusted Low, Moderate, and High XP budgets for the party level. The label is a rules-based estimate; monster abilities, terrain, resources, and party composition can change how difficult an encounter feels.
