Formula Explained

The maximum hit points for a D&D 5e character are calculated using the following formula:

Max HP = (Hit Dice × Level) + (Constitution Modifier × Level)

Where:

Hit Dice is the number of hit dice your class has (e.g., 8 for a fighter, 6 for a rogue)
Level is your character's current level
Constitution Modifier is your character's Constitution modifier (calculated as (Constitution Score - 10) ÷ 2)

For example, a level 5 fighter with a Constitution score of 16 would have a Constitution modifier of +3. Using the formula:

Max HP = (8 × 5) + (3 × 5) = 40 + 15 = 55

This means the fighter would have a maximum of 55 hit points at level 5.

Worked Examples

Let's look at two examples to illustrate how the calculator works.

Example 1: Fighter at Level 3

Inputs:

Constitution Modifier: +2
Class: Fighter (Hit Dice: 8)
Level: 3

Calculation:

Max HP = (8 × 3) + (2 × 3) = 24 + 6 = 30

Result: The fighter has a maximum of 30 hit points at level 3.

Example 2: Rogue at Level 4

Inputs:

Constitution Modifier: +1
Class: Rogue (Hit Dice: 6)
Level: 4

Calculation:

Max HP = (6 × 4) + (1 × 4) = 24 + 4 = 28

Result: The rogue has a maximum of 28 hit points at level 4.

These examples demonstrate how the calculator applies the formula to different character types and levels.
