What Are Hit Points in DnD 5e?
Hit points (HP) represent your character’s ability to survive damage in Dungeons & Dragons 5th Edition. When your HP reaches zero, your character falls unconscious and begins making death saving throws. The higher your HP, the longer you stay in the fight. HP is not just a number but the difference between a heroic victory and an early grave.
HP depends on three things: your class, your level, and your Constitution (CON) modifier. Our free HP calculator 5e handles all of this automatically, including multiclassing and special bonuses.
A Brief History of Hit Points in D&D
Hit points have been part of Dungeons & Dragons since Gary Gygax and Dave Arneson created the original game in 1974. The concept was borrowed from wargaming, where units had a set amount of damage they could absorb. Over five editions, the HP system evolved from a simple flat number into the structured, class-based formula we use in 5e today. The 2014 Player’s Handbook (PHB) standardized the current system, and the 2024 PHB (5.5e) refined rest mechanics and hit dice recovery — both of which our calculator supports.
How to Calculate HP in D&D 5e
At Level 1: You always get the maximum value of your class hit die, plus your CON modifier.
Formula: Max Hit Die + CON Modifier
Example: A Fighter (d10) with +2 CON at Level 1 = 10 + 2 = 12 HP
At Every Level After: You either roll your hit die or take the average (rounded up), then add your CON modifier.
Formula per level: (Hit Die Average or Roll) + CON Modifier
Most players and Dungeon Masters recommend using the average value for consistent, reliable HP growth.
D&D 5e Classes and Their Hit Dice
Each class uses a specific hit die that determines how much Hit Points you gain per level.
| Class | Hit Die | Avg HP/Level (no CON) |
|---|---|---|
| Barbarian | d12 | 7 |
| Fighter | d10 | 6 |
| Paladin | d10 | 6 |
| Ranger | d10 | 6 |
| Artificer | d8 | 5 |
| Bard | d8 | 5 |
| Cleric | d8 | 5 |
| Druid | d8 | 5 |
| Monk | d8 | 5 |
| Rogue | d8 | 5 |
| Warlock | d8 | 5 |
| Sorcerer | d6 | 4 |
| Wizard | d6 | 4 |
Barbarians are the tankiest class in the game. Wizards and Sorcerers have the lowest HP — they rely on spells and positioning instead of raw durability.
Feats and Racial Bonuses That Affect HP
Our calculator includes three important HP modifiers:
Tough Feat — Grants +2 HP per level. At Level 10 that is +20 HP total. One of the best defensive feats in the game.
Hill Dwarf — The Hill Dwarf racial trait grants +1 HP per level automatically.
Draconic Bloodline Sorcerer — This subclass grants +1 HP per level, making Sorcerers slightly more durable than a standard d6 class.
2014 PHB vs 2024 PHB — What Changed?
Our calculator supports both ruleset versions.
| Rule | 2014 PHB (Standard 5e) | 2024 PHB (New 5.5e) |

The 2024 update makes long rests significantly more powerful. If your Dungeon Master is running 5.5e rules, toggle to 2024 PHB in our calculator for accurate tracking.

Monster HP Calculator
Dungeon Masters can use the Monster HP tab to quickly determine any creature’s hit point range. Enter the number of hit dice, the die size (d4 through d12), and the CON modifier. The calculator returns:
- The average HP (used in the Monster Manual)
- The minimum possible HP
- The maximum possible HP
- A full breakdown of the formula
This is especially useful when customizing monsters or scaling encounters for your party’s level. Every formula in this calculator is built on the same rules Wizards of the Coast established in the D&D Basic Rules — so you can trust the numbers whether you are at the table or planning your next session.
