Dnd 5e Encounter Calculator
Balancing a Dungeons & Dragons 5th Edition fight comes down to two totals: what the monsters are worth in XP, and what your party can handle at each difficulty. This calculator does the full Dungeon Master’s Guide encounter method for you: party XP thresholds by level, raw monster XP, the official monster-count multiplier with the party-size shift, and a Trivial to Deadly verdict.
It is pre-filled with a classic test case: four 5th-level characters against four ogres (CR 2 each). The raw XP is 1,800, the multiplier for four monsters is x2, and the adjusted 3,600 XP lands on Hard. Keep the two XP numbers separate in your head: raw XP is the award, adjusted XP only measures the danger.

How to use the encounter calculator
Enter the party first, then the monsters, then read the verdict against the thresholds. Three format details decide whether the answer is right.
Party size and levels must agree. If the party box says 4, the levels box needs four numbers. Mixed-level parties are handled the DMG way: each level is looked up on its own and the thresholds are summed, so 3,3,4,5 is priced differently from four 4th-level characters even though both parties average out near the same place.
Monsters go in as CR:count groups. One group per monster type: “2:4” is four CR 2 monsters, “1:1, 1/2:3” is one CR 1 monster plus three CR 1/2 monsters. Fractional ratings use slashes (1/8, 1/4, 1/2), and ratings run from 0 to 30. If you built the monster yourself and have not rated it yet, price it first with the D&D 5e CR calculator, then bring the rating back here.
Read raw and adjusted XP as different numbers. The result box prints both, on purpose. Raw XP is the award. Adjusted XP is the difficulty yardstick. Tools that show a single XP figure force you to guess which one it is, and guessing wrong in either direction corrupts the encounter: award adjusted XP and the party levels too fast, judge difficulty by raw XP and group fights look safer than they are.
How encounter difficulty is calculated
The method has three steps, all from the encounter building rules in the Dungeon Master’s Guide.
Step 1: party thresholds. Every character level carries four XP thresholds, one per difficulty band. Add the four bands across the whole party. A 5th-level character contributes 250 Easy, 500 Medium, 750 Hard, and 1,100 Deadly, so four of them set the party bar at 1,000 / 2,000 / 3,000 / 4,400.
Step 2: monster XP, raw then adjusted. Each challenge rating converts to XP (CR 1/2 is 100, CR 1 is 200, CR 2 is 450, up to CR 30 at 155,000). Multiply by counts and sum for the raw total. Then apply the encounter multiplier for the total monster count, shifted for party size, to get adjusted XP.
Step 3: the verdict. Adjusted XP below the Easy threshold is Trivial. From Easy up to Medium is Easy, then Medium, then Hard, and anything at or past the Deadly threshold is Deadly.
Multiplier by monster count: 1 monster x1, 2 x1.5, 3 to 6 x2, 7 to 10 x2.5, 11 to 14 x3, 15 or more x4.
Party-size shift: parties of 1 to 2 use the next higher multiplier; parties of 6 or more use the next lower one (a single monster against 6 plus characters drops to x0.5).
Verdict bands: below Easy = Trivial, then Easy, Medium, Hard, and Deadly at or above the Deadly threshold.
Why a multiplier at all? Action economy. Four ogres take four turns every round: four attacks, four chances to focus a character down, four piles of hit points to chew through. A single monster worth the same raw XP takes one turn. The multiplier is the DMG’s price on that difference, and it is the reason headcount changes a fight more than most DMs expect. Note what does not enter the math: a monster’s damage output is already priced into its CR, so there is no separate damage term. If you want to see how that damage was priced, the D&D average damage calculator shows the per-round math behind a stat block. Every one of those extra attacks is settled by dice, and the dice average calculator works out the exact expected average of any dice pool, including the drop-lowest rolls tabletop games use for ability scores.
Worked example: four ogres against a level 5 party
Four ogres is the smallest group that exposes bad multiplier math, which is why it is the pre-filled example. Run it by hand:
Thresholds: four 5th-level characters give 4 x (250 / 500 / 750 / 1,100) = 1,000 / 2,000 / 3,000 / 4,400. Raw XP: an ogre is CR 2, worth 450 XP, so four ogres total 1,800 XP. Multiplier: four monsters sits in the 3 to 6 band, x2, and a party of four triggers no size shift. Adjusted XP: 1,800 x 2 = 3,600. Verdict: 3,600 is at or past Hard (3,000) and below Deadly (4,400), so the encounter is Hard. Award: 1,800 raw XP split four ways, 450 each. Adventuring day: four 5th-level characters carry a daily XP budget of 4 x 3,500 = 14,000 XP, and this fight’s 3,600 adjusted XP spends 26% of it, roughly a quarter of what the DMG expects the party to handle before a long rest.
Cross-check with the DMG’s own printed example, which this calculator reproduces exactly: a party of three 3rd-level characters and one 2nd-level character (thresholds 275 / 550 / 825 / 1,400) against one bugbear (CR 1, 200 XP) and three hobgoblins (CR 1/2, 100 XP each). Raw 500 XP, four monsters, x2, adjusted 1,000 XP, Hard. Try it: players 4, levels 3,3,3,2, monsters 1:1, 1/2:3. A tool that calls that fight Medium is not running the DMG numbers.
XP thresholds by character level
These are the per-character values the calculator sums. Nothing here is averaged: a mixed party is the sum of its members’ rows, which is why one low-level character drags the Deadly bar down less than a full party of their level would.
| Level | Easy | Medium | Hard | Deadly |
|---|---|---|---|---|
| 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 |
| 8 | 450 | 900 | 1,400 | 2,100 |
| 9 | 550 | 1,100 | 1,600 | 2,400 |
| 10 | 600 | 1,200 | 1,900 | 2,800 |
| 11 | 800 | 1,600 | 2,400 | 3,600 |
| 12 | 1,000 | 2,000 | 3,000 | 4,500 |
| 13 | 1,100 | 2,200 | 3,400 | 5,100 |
| 14 | 1,250 | 2,500 | 3,800 | 5,700 |
| 15 | 1,400 | 2,800 | 4,300 | 6,400 |
| 16 | 1,600 | 3,200 | 4,800 | 7,200 |
| 17 | 2,000 | 3,900 | 5,900 | 8,800 |
| 18 | 2,100 | 4,200 | 6,300 | 9,500 |
| 19 | 2,400 | 4,900 | 7,300 | 10,900 |
| 20 | 2,800 | 5,700 | 8,500 | 12,700 |
What other encounter calculators miss
The heavyweight builders, Kobold Fight Club and the D&D Beyond Encounter Builder, pick monsters from a full database with filters for type and environment. That is genuinely useful for browsing, and genuinely slow for a quick check: if you already know you want four ogres, typing “2:4” beats searching a compendium four times. D&D Beyond’s builder also sits behind an account. The quick calculators have different problems, and they are worth knowing because the errors are quiet:
Softened multipliers. A softened variant of the multiplier table circulates among quick tools: x1.2 for two monsters, x1.5 for 3 to 6, x1.75 for 7 to 10, x2 for 11 plus. Those are not the DMG values. Run four ogres through them and a Hard fight (3,600 adjusted) comes out as 2,700 and gets called Medium. Group fights are exactly where the error bites, so check any tool against the table in the formula box before trusting it.
No party-size shift. Omni Calculator’s encounter tool is strong on explanation and prints the correct base table, but its worked example never applies the small and large party adjustment, and its example text miscounts its own monsters (five creatures described as four). The shift matters most at the tables where quick tools get used: two-player duet games and six-player open tables.
Worked examples that fail their own math. One ranking encounter calculator walks through two CR 2 monsters against four 4th-level characters, computes 1,350 adjusted XP, and calls the fight Hard. The party’s Hard threshold is 1,500; 1,350 is Medium. If the example is wrong, the tool behind it deserves a second look.
One XP number, unexplained. Several tools display a single “total XP” that is actually the adjusted figure. That mislabels the award and teaches DMs to hand out multiplier XP. This page prints raw and adjusted side by side, labelled, every time. The wider combat picture is printed too: XP per player and the party’s adventuring day XP budget sit alongside the verdict in the same result box, so one run prices both the fight and its share of the day.
Many monsters or one big monster?
Two encounters can carry the same adjusted XP and play completely differently. The multiplier narrows the gap; it does not close it.
A group of monsters
- More turns per round, so steadier pressure and more chances to surround or focus one character
- Area spells and crowd control punch above their weight against grouped targets
- Morale, reinforcements, and split objectives are easy to stage
- Risk: the fight bogs down, and focused fire can delete a character before the party reacts
One big monster
- One stat block to run, one initiative count, a cleaner boss-fight feel
- The party can focus everything on one target, so single monsters often feel easier than their rating
- Legendary actions and resistances exist to patch exactly that action gap
- Risk: one failed save or one big crit streak swings the whole fight
A practical rule from the math: if the verdict surprises you, check the headcount before the CRs. Dropping from four monsters to three changes both the raw total and the multiplier band at 7 to 10 and 11 to 14 boundaries, and adding one cheap minion to a solo fight can move the multiplier a full step while barely touching raw XP.
Pacing the adventuring day
A single verdict is not a session plan. The DMG expects a party to handle roughly six to eight Medium or Hard encounters between long rests, with about two short rests mixed in, and its daily XP budget table exists to keep that total honest. In practice most tables run fewer, bigger fights, which pushes each encounter toward Hard and Deadly and makes nova classes look stronger than the math assumes.
Use this calculator as the per-fight check inside that bigger budget: rate each planned fight, note its adjusted XP, and keep a running total against what the party can spend in a day. The result box starts that total for you: it prints the party’s daily budget from the DMG table and the percentage of it this encounter spends. A day of one Deadly fight and nothing else plays nothing like a day of five Medium fights at the same total, and the difference is resource drain, not difficulty labels. Terrain, surprise, and a party that starts the fight already hurt all sit outside the XP math entirely; the verdict is the starting point for judgment, not a substitute for it.
Frequently asked questions
It totals the XP of your monsters, applies the DMG encounter multiplier for the monster count and party size, and compares the adjusted XP with your party’s XP thresholds to rate the fight Trivial, Easy, Medium, Hard, or Deadly.
Raw XP is the sum of the monsters’ XP values, and it is what the party earns, split evenly. Adjusted XP is raw XP multiplied by the encounter multiplier. It measures difficulty only and is never awarded.
Because action economy matters. Four monsters take four turns of actions and attacks each round, so a group is more dangerous than a single monster worth the same raw XP. The multiplier prices that extra pressure when judging difficulty.
For parties of three to five, the standard table applies. Parties of one or two use the next higher multiplier, and parties of six or more use the next lower one, down to x0.5 for a single monster facing six or more characters.
Yes. Enter every character’s level in order, for example 3,3,4,5. The calculator looks up each level’s thresholds separately and sums them, which is how the DMG handles mixed-level parties.
The adjusted XP is below the party’s Easy threshold. The fight should cost the party almost nothing: no meaningful resources, no real risk. Trivial fights still earn their raw XP.
The raw monster XP divided evenly by the number of players, never the adjusted XP. Four ogres (CR 2, 450 XP each) award 1,800 XP in total, which is 450 XP per player in a party of four.
It is the DMG’s estimate of how much adjusted XP a party can handle between long rests, summed per character from the Adventuring Day XP table: 3,500 XP for a 5th-level character, 40,000 XP for a 20th-level one. The calculator prints the party’s total budget and the share of it this encounter spends, so a Hard fight that uses 26% of the day reads differently from one that uses 90%.
Yes. The calculator only needs each monster’s challenge rating. If you built the monster yourself and do not know its CR yet, rate it first with a challenge rating calculator, then enter that CR here.
