Formula:

The HP Calculator 5e uses the standard D&D 5th Edition formula for calculating a creature's average hit points, based on its Hit Dice and Constitution Modifier:

  • Average HP = (Number of Hit Dice × Average Roll per Die) + (Number of Hit Dice × Constitution Modifier)
  • Minimum HP = (Number of Hit Dice × 1) + (Number of Hit Dice × Constitution Modifier)
  • Maximum HP = (Number of Hit Dice × Die Type Max) + (Number of Hit Dice × Constitution Modifier)

Where:

  • Number of Hit Dice: The quantity of dice rolled for the creature's HP (e.g., 5 for 5d8).
  • Average Roll per Die: The average value of the specific die type (e.g., 4.5 for d8).
  • Die Type Max: The maximum value of the specific die type (e.g., 8 for d8).
  • Constitution Modifier: The creature's Constitution modifier (can be positive or negative).
