Hit Point Calculator

Creating a powerful Dungeons & Dragons (D&D) character requires more than creativity—it takes strategic planning. One of the most vital stats for any character is Hit Points (HP). Whether you’re a tanky barbarian or a stealthy rogue, calculating hit points correctly can mean the difference between life and death in combat.

    • d10 (Fighter, Paladin, Ranger)
    • d12 (Barbarian)
  4. Choose Calculation Method:

    • Maximum First Level – Gives max HP per level (standard rule for first level).
    • Manual Entry – Enter your custom base HP.
  5. Input Additional HP (Optional) – From feats like Tough, magic items, or racial bonuses.

🧮 Example Calculation

Let’s say you’re building a Level 5 Paladin with the following:

  • Constitution modifier: +2
  • Hit Dice: d10
  • Calculation Method: Average
  • Additional HP: +5 (from the Tough feat)

Step-by-step:

  • Level 1 HP: Max = 10
  • Levels 2-5 Average: (10+1)/2 = 5.5 → Rounded down to 5
    5 × 4 = 20
  • Con Bonus: 2 × 5 = 10
  • Additional: +5

Total HP = 10 (first) + 20 (avg) + 10 (con) + 5 (bonus) = 45 HP
