The D&D encounter XP calculator determines whether your planned encounter is Easy, Medium, Hard, or Deadly by calculating adjusted XP based on monster count and comparing to party thresholds.

How to Use the D&D Encounter XP Calculator
Balancing D&D encounters is one of the DM's most important skills. This D&D encounter XP calculator uses the official 5e encounter building system to tell you if your planned fight is trivially easy or lethally dangerous.
Step 1: Enter your party details
Select the number of players and their level. If party members have different levels, use the average. Most groups play 3-5 players at the same level.
Step 2: Add your monsters
Add each monster's Challenge Rating. The tool automatically looks up XP values. A CR 1 monster is worth 200 XP; CR 5 = 1,800 XP; CR 10 = 5,900 XP. Adjust quantity — numbers matter enormously due to the XP multiplier.
Step 3: Aim for the right difficulty
For a standard adventuring day (6-8 encounters), mix Easy and Medium encounters with 1-2 Hard encounters and one Deadly encounter. A single Deadly encounter as the dungeon boss is satisfying; back-to-back Deadly encounters drain party resources to zero.

What is adjusted XP in D&D 5e?
Adjusted XP multiplies the total monster XP by a multiplier based on the number of monsters to account for action economy. 1 monster = 1x, 2 = 1.5x, 3-6 = 2x, 7-10 = 2.5x, 11-14 = 3x, 15+ = 4x. A group of 10 zombies (25 XP each = 250 total) has 625 adjusted XP — much harder than one 250-XP monster.
What are the encounter difficulty thresholds?
Each character level has XP thresholds for Easy, Medium, Hard, and Deadly encounters. These scale by level. At level 5, a 4-person party thresholds: Easy=1,000, Medium=2,000, Hard=3,000, Deadly=4,400 adjusted XP. Below Easy is a trivial encounter.
What Challenge Rating monsters should I use for my party level?
CR = party level is roughly a Medium encounter for a 4-person party. CR = party level − 3 is Easy/trivial. CR = party level + 2 is Hard. CR = party level + 4 is potentially Deadly. These are rough rules of thumb — actual difficulty varies with party composition and resources.
Does this include 2024 rules revisions?
This calculator uses the 5e (2014 PHB) encounter difficulty system. The 2024 Player's Handbook revises some mechanics but the core encounter building framework remains similar. Always adjust for your specific table's power level and resources.
