How to use this tool?
This calculator computes your Dungeons & Dragons character's maximum hit points (HP) using the standard fixed-HP-per-level rule.
- Select your Class – Choose from the dropdown. The hit die size (d12, d10, d8, or d6) is automatically applied.
- Enter your Level – A number between 1 and 20.
- Enter your Constitution Modifier – Your Con ability score modifier (typically -5 to +10).
- Check optional bonuses (if applicable):
- Tough Feat – Adds +2 HP per level.
- Hill Dwarf (Dwarven Toughness) – Adds +1 HP per level.
- Click "Calculate HP" – Your total hit points appear below, along with a full formula breakdown showing each level's contribution.
Important: The calculator uses the standard rule: at level 1 you get the full hit die + Con mod (minimum 1). For each level after 1, you add the average roll (half the die size + 1) + Con mod (minimum 1 per level).
