E5 Dnd Health Calculator

This calculator helps you determine your Dungeons & Dragons 5th Edition character's health points (HP) based on your character class, level, and constitution modifier. Understanding your character's HP is crucial for survival in combat and long-term campaign health.

How to Use This Calculator

To calculate your character's health points:

Select your character class from the dropdown menu.
Enter your character level (1-20).
Enter your constitution modifier (typically between -5 and +6).
Click "Calculate" to see your results.

The calculator will display your maximum HP at the current level, your average HP per level, and your total HP at the specified level.

Formula Used

The base HP calculation follows these rules:

Maximum HP at Level 1: Class Hit Die + Constitution Modifier

Maximum HP at Higher Levels: (Hit Die / 2 + 1) + Constitution Modifier per level

Total HP at Current Level: Sum of all HP gains from level 1 to current level

Each class has a different hit die size:

Barbarian, Fighter, Paladin, Ranger: 1d12
Bard, Cleric, Druid, Monk, Rogue, Warlock: 1d8
Sorcerer, Wizard: 1d6

Worked Example

Let's calculate the HP for a level 5 Fighter with a +3 constitution modifier:

Level 1: 12 (1d12) + 3 = 15 HP
Level 2: 7 (1d12/2 + 1) + 3 = 10 HP
Level 3: 7 + 3 = 10 HP
Level 4: 7 + 3 = 10 HP
Level 5: 7 + 3 = 10 HP

Total HP at level 5: 15 + 10 + 10 + 10 + 10 = 55 HP

Note: This is the maximum HP your character can have. Actual HP in combat may be lower due to damage taken.

Character Class HP Progression

Here's a comparison of HP progression for different classes at level 5:

Class	Hit Die	Con Mod	Total HP
Fighter	1d12	+3	55
Ranger	1d10	+3	48
Paladin	1d10	+3	48
Bard	1d8	+3	38
Cleric	1d8	+3	38

FAQ

What is the difference between maximum HP and current HP?

Maximum HP is your character's full health at a given level. Current HP is what you have after taking damage in combat. You can't have more current HP than your maximum HP.

How does constitution affect my HP?

Your constitution modifier is added to your HP at each level. Higher constitution means more HP, which means you can take more damage before falling unconscious.

Can I have more than the calculated maximum HP?

No, the calculator shows your maximum possible HP based on your level and constitution. Some classes and feats can increase this, but that's beyond the basic calculation.

Why does my HP increase by different amounts at different levels?

At level 1, you get your full hit die plus your constitution modifier. At higher levels, you get half your hit die (rounded up) plus your constitution modifier each time you level up.
