D&D 5e HP Calculator
Enter your class, level, and Constitution modifier to get your maximum hit points in D&D 5th Edition. The calculator supports all 13 core classes, up to two multiclass combinations, the Tough feat, Hill Dwarf racial bonus, Draconic Bloodline Sorcerer bonus, and both the average and maximum HP methods. Your result updates as you type.
How HP works in D&D 5th Edition
Hit points represent how much punishment your character can absorb before falling unconscious. In D&D 5e, your maximum HP is determined by your class hit die, your level, and your Constitution (CON) modifier. At 1st level you always receive the maximum value of your class hit die, plus your CON modifier. At every level after that, you roll your hit die (or take the average, which most tables prefer) and add your CON modifier. A positive CON modifier increases HP at every level, while a negative modifier reduces it - meaning CON is the single most important ability score for staying alive in combat.
Average vs maximum HP methods
The Player Handbook offers two approaches for gaining HP at levels 2 and above. The rolled method has you physically roll your class hit die, add your CON modifier, and record that total. This creates variance: a lucky roll beats the average, but a terrible roll can leave you below it. The average method uses a fixed value equal to the median of the die, rounded up - for a d10 that is 6, for a d8 it is 5, for a d6 it is 4, and for a d12 it is 7. Most organized play (such as Adventurers League) requires the average method so all characters of the same class and level have predictable HP. Some home games allow taking maximum HP at every level to create more resilient characters and longer, more dramatic combats. Use the HP method selector above to compare both approaches for your character.
Multiclassing and how it affects HP
When your character gains a level in a second class through multiclassing, the new level uses that class's hit die, not your primary class die. For example, a Fighter 5 / Wizard 3 character has 5 levels of d10 rolls and 3 levels of d6 rolls, not 8 levels of d10. Only the very first level of your entire character career uses the "maximum roll" rule - any subsequent level, whether in the original class or a new one, uses either the average or the roll. Multiclassing into a class with a smaller hit die lowers your HP gain per level, while dipping into Barbarian (d12) raises it. Always weigh the HP cost of a multiclass dip against the class features you gain.
Feats and racial bonuses that boost HP
Three features can raise your HP beyond what class and CON provide. The Tough feat, available to any character as an Ability Score Improvement choice, adds 2 HP per character level and retroactively increases HP for all existing levels - making it more valuable the later you take it and the longer your campaign runs. Hill Dwarves receive Dwarven Toughness, a racial trait that adds 1 HP per level without spending a feat slot, giving them a long-run advantage in durability. Sorcerers who choose the Draconic Bloodline subclass gain Dragon Resilience at 1st level, adding 1 HP per sorcerer level - effectively making their hit die a d8 instead of a d6 in practice. The Bloodied condition, introduced in the 2024 revised rules, activates at or below half your maximum HP and affects certain monster abilities and spells, so knowing your bloodied threshold (shown in the results above) is increasingly relevant at tables using updated rules.

Frequently asked questions
How do I calculate my HP in D&D 5e?
At level 1, your HP equals the maximum value of your class hit die plus your Constitution modifier. At each level after that, you either roll your hit die or take the average (the die median rounded up), then add your CON modifier. Sum all these values across every level. Special features like the Tough feat add a fixed bonus per level on top. This calculator handles all the arithmetic for you.
What is the average HP per level for each class?
Using the average method: Barbarian gains 7 HP per level (d12), Fighter, Paladin, and Ranger gain 6 (d10), most mid-tier classes (Artificer, Bard, Cleric, Druid, Monk, Rogue, Warlock) gain 5 (d8), and Sorcerer and Wizard gain 4 (d6). These assume a CON modifier of 0 - add your CON modifier to each of these per-level numbers.
Does CON modifier apply at every level?
Yes. Your Constitution modifier is added once per character level, including 1st level. If your CON modifier changes during the game - such as when you take an Ability Score Improvement or gain the Tough feat - your maximum HP is recalculated retroactively, applying the new value to every level you have gained.
How does the Tough feat change my HP?
The Tough feat grants +2 HP per character level and applies retroactively. If you take it at level 8, you gain 16 HP immediately (2 per each of your 8 levels), then +2 HP at every future level. This makes it one of the most HP-efficient feats in the game for longer campaigns.
Can my HP ever go below 1 at level 1 with a negative CON modifier?
By the rules, a character always has at least 1 maximum hit point, even if the CON modifier would reduce the total to 0 or below. This calculator enforces that floor. Most Dungeon Masters also apply this common-sense rule for subsequent levels, although the Player Handbook technically only states it for maximum HP overall.
What is the bloodied condition and why does it matter?
The bloodied condition was introduced in the 2024 revised Player Handbook and triggers when a creature is at or below half its maximum HP. Some monster abilities, class features, and spells specifically interact with bloodied characters. Even at tables still using 2014 rules, tracking your midpoint HP helps you know when healing is critical before you drop to 0.
How does HP work when multiclassing?
Only the very first level of your character career grants maximum hit die HP. Every subsequent level, including the first level of a second class, uses either the roll or average method. Each class contributes its own hit die size for its levels - so a Barbarian 3 / Rogue 2 uses 3d12 rolls for the barbarian levels and 2d8 rolls for the rogue levels.
