5e Health Calculator

Reviewed by Calculator Editorial Team

Calculate your character's health points using the Dungeons & Dragons 5th Edition system. This calculator helps you determine your maximum hit points based on your character's level, constitution modifier, and hit dice.

How to Use This Calculator

To calculate your character's health points:

  1. Enter your character's level (1-20)
  2. Enter your constitution modifier (typically between -5 and +6)
  3. Select your hit dice type (d4, d6, d8, d10, d12)
  4. Click "Calculate" to see your results

The calculator will show your maximum hit points, average hit points per level, and a chart of your health progression.

Formula Explained

The 5E health calculation follows these rules:

Maximum Hit Points = (Hit Dice × Level) + (Constitution Modifier × Level)

Where:

  • Hit Dice is the type of die your character uses (d4, d6, d8, d10, d12)
  • Level is your character's level (1-20)
  • Constitution Modifier is your character's constitution modifier

For example, a level 5 fighter with a constitution modifier of +2 and d10 hit dice would have:

(10 × 5) + (2 × 5) = 50 + 10 = 60 maximum hit points

Worked Example

Let's calculate the health points for a level 3 character with these stats:

  • Level: 3
  • Constitution Modifier: +3
  • Hit Dice: d8

Using the formula:

(8 × 3) + (3 × 3) = 24 + 9 = 33 maximum hit points

This means your character starts with 33 hit points at level 3.

Frequently Asked Questions

What is the difference between hit points and hit dice?
Hit points represent your character's current health, while hit dice determine how many hit points you gain when you level up. Each class has a different hit die size.
How do I calculate my constitution modifier?
Your constitution modifier is calculated by subtracting 10 from your constitution score, then dividing by 2 (rounding down). For example, a constitution score of 16 gives a +3 modifier.
Can I use this calculator for any D&D 5E character?
Yes, this calculator works for any player character in Dungeons & Dragons 5th Edition. Just enter your level, constitution modifier, and hit dice type.
What happens if I have a negative constitution modifier?
A negative constitution modifier will reduce your total hit points. For example, a -1 modifier at level 5 with d10 hit dice would result in (10×5) + (-1×5) = 45 hit points.
Is there a maximum level for this calculator?
The calculator supports levels up to 20, which is the standard maximum level in most D&D 5E campaigns.
