Balancing a fight is one of the hardest parts of running Dungeons & Dragons. The rules give the Dungeon Master an XP-based method: every monster has a challenge rating (CR) with a fixed experience-point value, and every character level has XP thresholds for each difficulty. Adding up the party’s thresholds and the monsters’ XP tells you how dangerous an encounter is likely to be.
Under the 2014 rules, groups of monsters are more dangerous than their XP suggests because they get more actions, so the total monster XP is multiplied by an encounter multiplier that grows with the number of monsters – from ×1 for a single foe to ×4 for fifteen or more – and shifted one step for unusually small or large parties. The adjusted XP is compared with the party’s Easy, Medium, Hard and Deadly thresholds. The 2024 rules simplify this: they drop the multiplier and compare the plain XP total with Low, Moderate and High budgets per character.
Enter your party as a list of levels, add up to four groups of monsters by CR and any extra monsters by XP, and the calculator shows the rating, the thresholds, how much more XP would push the fight to the next tier and the XP each character earns.

How it works
List the characters’ levels, choose the rule set, then pick CR and number for each monster group. The tool sums thresholds per level, totals the monster XP, applies the multiplier for 2014 rules and returns the highest threshold the encounter reaches.
Worked example
A party of four 3rd-level characters has thresholds of 4 × 75 = 300 (Easy), 4 × 150 = 600 (Medium), 4 × 225 = 900 (Hard) and 4 × 400 = 1,600 (Deadly). Four CR 1/4 goblins (50 XP each) and a CR 1 leader (200 XP) total 400 XP. Five monsters use the ×2 multiplier, so the adjusted XP is 800 – a Medium encounter, 100 XP short of Hard. Each character earns 400 ÷ 4 = 100 XP. Under the 2024 budget (600 / 900 / 1,600) the same 400 XP is below Low.
XP thresholds per character (2014)

|---|---|---|---|---|
| 1 | 25 | 50 | 75 | 100 |
| 2 | 50 | 100 | 150 | 200 |
| 3 | 75 | 150 | 225 | 400 |
| 4 | 125 | 250 | 375 | 500 |
| 5 | 250 | 500 | 750 | 1,100 |
| 6 | 300 | 600 | 900 | 1,400 |
| 7 | 350 | 750 | 1,100 | 1,700 |

Formula
2014: party threshold = Σ per-character thresholds; adjusted XP = Σ monster XP × multiplier(number of monsters)
Multipliers: 1 ×1 · 2 ×1.5 · 3–6 ×2 · 7–10 ×2.5 · 11–14 ×3 · 15+ ×4 (one step up for parties under 3, one step down for 6+)
2024: compare total monster XP (no multiplier) with Σ per-character Low / Moderate / High budgets
Worked example
Inputs — Rule set: 2014 rules – Easy / Medium / Hard / Deadly; Character levels (one per character): 3, 3, 3, 3; Adjust for party size (fewer than 3 or 6+ characters): Yes; Monster group 1 – challenge rating: CR 1/4 (50 XP); Group 1 – number of monsters: 4; Monster group 2 – challenge rating: CR 1 (200 XP); Group 2 – number of monsters: 1; Monster group 3 – challenge rating: CR 2 (450 XP); Group 3 – number of monsters: 0; Monster group 4 – challenge rating: CR 4 (1,100 XP); Group 4 – number of monsters: 0; Extra monsters by custom XP (0 = none): 0.
Results — Encounter difficulty = Medium; Total monster XP = 400 XP; Number of monsters = 5; Encounter multiplier = ×2; Adjusted XP = 800 XP; Threshold 1 = Easy.
Key terms
- Challenge rating (CR)
- A monster's power level; a party of four characters of that level should be able to defeat one such monster.
- XP threshold
- The experience-point value that marks each difficulty level for one character.
- Encounter multiplier
- 2014-rules factor that raises the effective XP of fights with several monsters.
- Adventuring day
- The amount of encounters a party can handle between long rests – about 6–8 medium or hard fights under 2014 guidance.
Frequently asked questions
How do you calculate encounter difficulty in 5e?
Add each character's XP threshold to get the party's thresholds, add up the monsters' XP, multiply by the encounter multiplier (2014 rules) and see which threshold the result reaches.
What are the encounter multipliers?
×1 for one monster, ×1.5 for two, ×2 for 3–6, ×2.5 for 7–10, ×3 for 11–14 and ×4 for 15 or more. Parties of 1–2 characters use the next higher multiplier, parties of 6+ the next lower.
Is the multiplier used for XP rewards?
No – characters earn the unadjusted XP, divided among them. The multiplier only measures difficulty.
What changed in the 2024 rules?
The multiplier and the Easy/Deadly tiers are gone: you compare the total XP with Low, Moderate and High budgets per character, which are also generally higher than the 2014 thresholds.
Is four goblins and a CR 1 monster hard for level-3 characters?
Under 2014 rules: 4 × 50 + 200 = 400 XP, × 2 for five monsters = 800 XP, against thresholds of 300 / 600 / 900 / 1,600 – Medium.
What counts as a Deadly encounter?
One whose adjusted XP meets the party's Deadly threshold; it may kill one or more characters without luck or good tactics.
Should weak minions count toward the multiplier?
The 2014 guidance says you may ignore monsters whose CR is far below the average CR of the group.
