D&D Encounter Balance: How to Set Difficulty at Your Table
Learn how to balance D&D 5e encounters with XP budgets, the 2014 and 2024 difficulty rules, worked examples and fixes you can make mid-fight.
A balanced D&D encounter is one that is neither a pushover nor a wipe for your party. To build one, pick a difficulty, work out your party's XP budget from character level and party size, and spend that budget on monsters. Then adjust for the things the math cannot see: how rested the party is, the terrain, and how many actions each side gets per round. This guide covers both rulesets, 2014 and 2024, with worked examples.
TL;DR
Encounter balance is the match between a fight's danger and your party's resources. Too easy bores players, and too hard risks a total party wipe.
The 2014 rules use four tiers (Easy, Medium, Hard, Deadly) and a monster-count multiplier. The 2024 rules use three tiers (Low, Moderate, High) and no multiplier.
Build in four steps: choose a difficulty, find the XP budget, multiply by party size, then add monsters that fit.
Treat the result as a starting point. Resources, terrain and action economy can move a fight up or down a full tier.
Keep a few on-the-fly levers ready: reinforcements, fleeing monsters and hit points within the dice range.

What encounter balance actually means
Encounter balance is the difficulty of a fight relative to the party. An unbalanced encounter is much too easy or much too hard. It helps to know what each tier promises, because the labels are about outcomes, not numbers.
The 2014 Dungeon Master's Guide defines four categories on page 82:
Easy: doesn't tax the party's resources, and victory is pretty much guaranteed.
Medium: one or two scary moments, but no casualties. Healing resources may be needed.
Hard: could go badly. Weaker characters might get taken out, with a slim chance of a death.
Deadly: could be lethal for one or more characters. Survival takes good tactics and quick thinking.
The 2024 rules collapse these into three. According to the SRD combat encounters page, a Low encounter has one or two scary moments, and the characters should win with no casualties. A Moderate encounter could go badly without healing, and there is a slim chance someone dies. A High encounter could be lethal for one or more characters and calls for smart tactics, quick thinking and maybe a little luck.
One thing to settle before you open any chart: balance is not a single number. One designer-minded blogger argues that a balanced fight is one where the table felt threatened enough to care, free enough to be clever and done before patience thinned. That is a good target for the rest of this guide. The math gets you close, and your read of the table does the rest.
Which ruleset are you using?
The two systems produce different numbers, so pick one and stay with it for the whole encounter.
| | 2014 rules | 2024 rules |
| Difficulty tiers | Easy, Medium, Hard, Deadly | Low, Moderate, High |
| Monster-count multiplier | Yes | No |
| What you compare | Adjusted monster XP vs. summed party thresholds | Raw monster XP vs. party budget |
| Adventuring day | 6 to 8 Medium or Hard encounters for 3 to 5 characters | Dropped |
The comparison of the two methods comes down to this: 2014 compares adjusted XP to summed thresholds, while 2024 compares raw monster XP to a budget of per-character XP times party size.
The designers changed this deliberately. In an interview, senior game designer James Wyatt said the old multiplier "didn't work properly" and that the math was off. Separately, a simulation study published in April 2025 found the 2024 rules predict the damage a party takes correctly, while the 2014 rules overestimate it by around 32%. That study also found 2014 is most accurate for single-monster fights and overestimates more as monster count rises.
If your table plays 2024 or a mix, the budget method is simpler. If you run 2014 modules, use the older method. The monster stat blocks mostly carry over either way.
