Calculate your character’s hit points accurately with class, level, and Constitution modifier. Includes average and maximum HP options with visual breakdown.

Comprehensive Guide to Calculating Hit Points in D&D 5e

Hit Points (HP) represent your character’s vitality and ability to withstand damage in Dungeons & Dragons 5th Edition. Understanding how to calculate HP correctly is essential for both new and experienced players. This guide covers everything from basic HP calculation to advanced considerations like multiclassing and special features.

1. The Core HP Formula

The basic formula for calculating hit points in D&D 5e is:

Total HP = (Base HP from Class) + (Constitution Modifier × Level) + (Other Bonuses)

2. Base HP by Class

Each class has a specific Hit Die that determines their base HP per level:

Class	Hit Die	Average HP per Level	Maximum HP per Level
Barbarian	d12	7	12
Fighter	d10	6	10
Paladin, Ranger	d10	6	10
Cleric, Druid	d8	5	8
Bard, Monk, Rogue, Warlock	d8	5	8
Artificer, Sorcerer, Wizard	d6	4	6

3. Constitution Modifier Impact

Your Constitution modifier adds to your HP at every level. For example:

• A Constitution score of 14 gives a +2 modifier
• This +2 is multiplied by your character level
• At level 5 with +2 CON: 2 × 5 = +10 HP

4. Level 1 vs. Higher Levels

Special rules apply to your first level:

1. Level 1: You get maximum HP from your Hit Die plus Constitution modifier
2. Levels 2+: You can either:
   • Roll your Hit Die and add Constitution modifier
   • Take the average (rounded up) plus Constitution modifier
   • Always take the maximum (with DM permission)

5. Special Features Affecting HP

Tough Feat

Grants +2 HP per level (retroactive). At level 10: +20 HP total.

Draconic Sorcerer

Gains +1 HP per sorcerer level from Draconic Resilience.

Hill Dwarf

Gains +1 HP per level due to racial Dwarven Toughness.

6. Multiclassing Rules

When multiclassing, you:

• Use the Hit Die of your new class for each level taken
• Add Constitution modifier as normal
• Don’t get retroactive HP from previous levels

Multiclass HP Comparison (Level 5 Character)

Class Combination	Total HP (CON +2)	Average HP per Level
Single-class Barbarian	52	10.4
Fighter 3/Rogue 2	38	7.6
Cleric 2/Wizard 3	29	5.8
Paladin 1/Sorcerer 4	30	6.0

7. Common HP Calculation Mistakes

1. Forgetting Level 1 Maximum: Many players roll for level 1 HP when they should take maximum.
2. Incorrect Constitution Application: Some add CON once instead of per level.
3. Feat Timing: Taking Tough after level 4 doesn’t grant retroactive HP.
4. Multiclass Confusion: Using wrong Hit Die for new class levels.
5. Fractional Averages: Not rounding up when taking average HP.

8. Optimizing Your HP

To maximize survivability:

• Prioritize Constitution as your second-highest stat
• Consider the Tough feat if you have odd Constitution
• Choose races with HP bonuses (Hill Dwarf, Goliath)
• Select subclasses with defensive features
• Use magic items that boost Constitution

9. Temporary Hit Points

While not part of your base HP calculation, temporary HP (THP) is important:

• Doesn’t stack with other THP
• Lasts until used or you finish a long rest
• Common sources: Aid spell, Heroism, some class features

10. House Rules and Variants

Some DMs use alternative rules:

• Heroic HP: All classes use d10 Hit Die
• Gritty Realism: HP represents stamina more than physical wounds
• Maximum HP: All characters take maximum HP at each level
• Constitution Scaling: CON modifier increases at certain levels
