Formula Explained

The D&D 5E Health Calculator uses the following formulas to calculate hit points and hit dice:

// Base Hit Points baseHP = classHitDice * (level - 1) + classHitDice // Total Hit Points totalHP = baseHP + (constitutionModifier * level) // Hit Dice hitDice = classHitDice + "d" + classHitDieSize

Where:

classHitDice is the number of hit dice for your character's class (e.g., 1 for Fighter, 1 for Rogue)
classHitDieSize is the size of the hit die for your character's class (e.g., 10 for Fighter, 8 for Rogue)
level is your character's level
constitutionModifier is your character's Constitution modifier

These formulas are based on the official D&D 5E rules for character creation and leveling.

Worked Examples

Let's look at a couple of examples to see how the calculator works.

Example 1: Level 5 Fighter

For a level 5 Fighter with a Constitution modifier of +3:

Class Hit Dice: 1d10
Base HP: 1d10 × (5 - 1) + 1d10 = 4d10 + 1d10 = 5d10
Total HP: 5d10 + (3 × 5) = 5d10 + 15
Average HP: (5 × 5.5) + 15 = 27.5 + 15 = 42.5 (rounded to 43)

Example 2: Level 3 Rogue

For a level 3 Rogue with a Constitution modifier of +2:

Class Hit Dice: 1d8
Base HP: 1d8 × (3 - 1) + 1d8 = 2d8 + 1d8 = 3d8
Total HP: 3d8 + (2 × 3) = 3d8 + 6
Average HP: (3 × 4.5) + 6 = 13.5 + 6 = 19.5 (rounded to 20)

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 much health you regain when you take a short rest. Each class has a different number and size of hit dice.

How do I calculate my Constitution modifier?

Your Constitution modifier is calculated by subtracting 10 from your Constitution score and then dividing by 2 (rounding down). For example, a Constitution score of 16 gives a modifier of +3.

Can I use this calculator for monsters?

Yes, you can use this calculator for monsters as well. Simply enter the monster's level, hit dice, and Constitution modifier to calculate its health.

What if I want to adjust my character's health?

You can adjust your character's health by changing the inputs in the calculator and recalculating. This is useful for balancing your character or creating custom variants.
