D&D 5e Encounter Difficulty Calculator
Build balanced D&D 5th Edition encounters: enter party size, average level, number of monsters and XP per monster to get the adjusted encounter XP, difficulty rating and the party's Easy / Medium / Hard / Deadly thresholds.

How does this calculator work?
Adjusted encounter XP = (monsters × XP each) × monster-count multiplier (1× to 4×, adjusted up for small parties, down for large ones). Compare to party thresholds (sum of per-character Easy/Medium/Hard/Deadly values by level from the 2014 DMG). Players receive raw XP — not adjusted — for levelling. These rules are from the 2014 D&D 5e DMG.
Formula
How this is calculated
The D&D 5e Dungeon Master's Guide defines encounter difficulty using per-character XP thresholds that scale by level. Each character has four threshold values (Easy, Medium, Hard, Deadly); you sum them across all party members to get party-wide targets. Raw encounter XP is the sum of each monster's listed reward from its stat block.
Because multiple monsters are disproportionately dangerous — they spread damage faster, apply stacking conditions, and limit focus-fire — a multiplier is applied to raw XP to produce "adjusted XP" for difficulty comparison: one monster ×1, two ×1.5, three to six ×2, seven to ten ×2.5, eleven to fourteen ×3, fifteen or more ×4. For parties of 1–2 players the multiplier steps up one tier (greater individual threat); for parties of 6+ it steps down one tier (action-economy advantage to the party).
Adjusted XP is compared to the party thresholds only for difficulty classification. The XP actually awarded to players for levelling is always the raw total (not adjusted), divided equally among surviving party members. These rules come from the 2014 5e DMG; the 2024 revised DMG uses a different "encounter budget" system.
Frequently asked questions
Multiple enemies create an action-economy advantage: they can attack multiple characters per round, concentrate fire to down one PC quickly, and apply overlapping conditions. The multiplier compensates for this — five 100-XP goblins are a substantially harder fight than one 500-XP monster, even though their raw XP is equal.
Raw XP is the sum of the monsters' listed XP values — this is what characters earn for levelling, divided equally among the party. Adjusted XP (raw × multiplier) is a bookkeeping number used only to classify difficulty; it is never given to players.
The DMG suggests a typical adventuring day includes 6–8 encounters worth of Medium or Hard challenge before a long rest. In practice, many DMs run fewer but more impactful encounters: one or two Medium resource-draining fights and one climactic Hard or Deadly encounter per session keeps tension high without grinding the party down.
