This calculator helps you determine your Dungeons & Dragons 5th Edition character's hit points and health progression based on their Constitution score. Whether you're creating a new character or leveling up an existing one, this tool provides quick and accurate health calculations.

How to Use This Calculator

Using the DnD 5e Con Health Calculator is simple:

  3. Enter your character's current level.
  4. Click the "Calculate" button to see your hit points.

The calculator will display your total hit points, hit dice, and a chart showing your health progression over levels.

Formula Used

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

Hit Points = (Hit Dice × Constitution Modifier) + Hit Points per Level × (Level - 1)

Where:

  • Hit Dice is the die type your class uses (e.g., d8 for fighters, d6 for rogues)
  • Constitution Modifier is calculated as (Constitution Score - 10) ÷ 2
  • Hit Points per Level is the average roll of your hit dice plus your Constitution modifier

Note: Some classes have special rules for hit points at 1st level and may use different hit dice for certain levels.

Worked Example

Let's calculate hit points for a level 5 Fighter with a Constitution score of 16:

  1. Constitution Modifier = (16 - 10) ÷ 2 = +3
  2. Fighters use d10 hit dice
  3. Average d10 roll = 5.5
  4. Hit Points at 1st level = 10 + Constitution Modifier = 10 + 3 = 13
  5. Hit Points per level = 5.5 + 3 = 8.5
  6. Total Hit Points = 13 + (8.5 × 4) = 13 + 34 = 47

This example shows the Fighter gaining 8.5 hit points per level after the first level.

Character Health Progression

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

Class Con 16 Con 10 Con 8
Fighter 47 37 27
Rogue 43 33 23
Wizard 35 25 15
Barbarian 55 45 35

This table shows how Constitution score affects health progression across different classes.

Frequently Asked Questions

How do I calculate my Constitution modifier?

Subtract 10 from your Constitution score, then divide by 2 (rounding down). For example, a Constitution of 16 gives a modifier of +3.

Does this calculator account for racial bonuses?

No, this calculator uses your base Constitution score. You'll need to add any racial bonuses manually.

Why does my character's hit points vary from the table?

DnD 5e uses an average roll for hit points, but actual rolls can vary. This calculator shows the expected average values.

How does Constitution affect healing?

Constitution primarily affects hit points and hit dice. It doesn't directly affect healing rates in the base rules.
