D&D 5e Hit Points Calculator

How hit points are calculated

Your hit point maximum comes from your class's hit die and your Constitution modifier. The rule is the same in the 2014 and 2024 rules:

The fixed value is half the die plus one: 4 for a d6, 5 for a d8, 6 for a d10 and 7 for a d12. It is slightly higher than the true average of a roll (3.5, 4.5, 5.5 and 6.5), which is why most players take it instead of rolling.

Hit dice by class

The last two columns assume a Constitution of 14 or 15 (+2) and the fixed value at every level after 1st.

How to use this calculator

1. Choose your starting class and its level. For a multiclass character, add each extra class with Add a multiclass.
2. Enter your current Constitution score. If it went up over the campaign, use the new score: the change applies to every level retroactively.
3. Pick a method: Fixed average (the default rule), Rolled (roll in the calculator or type in the rolls from your table), or Maximum if your table uses that house rule.
4. Tick any features that add hit points, such as the Tough feat.

Multiclassing and hit points

Only your very first class gives you the maximum hit die at 1st level. When you take a level in a second class, you gain that class's hit die as if it were any other level: rolled or at the fixed value. That is why a Wizard 1 / Fighter 4 has fewer hit points than a Fighter 1 / Wizard 4 would at level 1, but more by level 5.

This calculator assumes you took all levels of your starting class before the others. If you alternated classes, the total is the same unless you used the rolled method; only the level-by-level order changes.

Features that add hit points

• Tough feat — +2 hit points per character level, in both editions.
• Dwarven Toughness — +1 hit point per character level. In the 2014 rules this comes from the Hill Dwarf subrace; in the 2024 rules every Dwarf has it.
• Draconic resilience — the draconic sorcerer subclass adds hit points for each Sorcerer level. In the 2014 rules you gain +1 per Sorcerer level from 1st level. In the 2024 rules the subclass starts at Sorcerer level 3 with +3 hit points, then adds +1 for each further Sorcerer level.
• Constitution increases — raising your Constitution from 15 to 16 increases your modifier by 1, which adds 1 hit point for every level you have.

Rolling or taking the average?

The fixed value beats the true average of a roll by 0.5 per level, and it never leaves you with a disastrous 1. Over 19 levels after 1st, a d10 character taking the fixed value ends up about 10 hit points ahead of the average roller. Rolling gives you a chance at a tougher character, at the risk of a fragile one. If your table rolls, use the Rolled option and enter your real results so the total stays accurate.
