Last Updated: February 13, 2026

Welcome to dndhpcalculator.com — a completely free, unofficial, fan-created online tool specifically designed to help Dungeons & Dragons players quickly and easily calculate Hit Points (HP) for their characters under Dungeons & Dragons 5th Edition (D&D 5e) rules, with full support for the 2024 Player’s Handbook (PHB) updates, multiclassing, the Tough feat, racial/species bonuses, combat statistics, high-level play including Epic Boons, and other common character-building options.

Important: This is NOT an official Dungeons & Dragons tool. dndhpcalculator.com is an independent, community-driven fan project created by enthusiasts for enthusiasts. It has no affiliation, endorsement, sponsorship, or approval from Wizards of the Coast LLC, Hasbro Inc., or any official D&D publisher or licensee. All references to Dungeons & Dragons mechanics, classes, species, feats, spells, and other elements are used solely under the limited permissions granted by the Wizards of the Coast Fan Content Policy (available here: https://company.wizards.com/en/legal/fancontentpolicy).

Purpose of This Tool

This HP calculator exists purely for entertainment, educational, and convenience purposes. It helps players:

  • Estimate starting and level-up hit points based on class hit dice, Constitution modifier, and other standard factors.
  • Explore multiclass combinations and feat impacts (e.g., Tough feat adding +2 HP per level).
  • Compare options under the 2024 PHB ruleset, including any relevant previews or clarifications for high-level features like Epic Boons.

It is not a substitute for the official Player’s Handbook, Dungeon Master’s Guide, or any other Wizards of the Coast publications. Players and Dungeon Masters should always refer to official rulebooks for final rulings.

Accuracy and Limitations

While we strive to make calculations accurate based on publicly available rules from the System Reference Document (SRD), the 2024 Player’s Handbook, and common community interpretations:

  • We provide no warranty — express, implied, or otherwise — regarding the accuracy, completeness, reliability, or suitability of any results generated by this tool.
  • Results may vary due to:
    • House rules or homebrew content used at your table.
    • Dungeon Master (DM) interpretations or house rulings on ambiguous mechanics.
    • Official errata, Sage Advice Compendium updates, or future rule changes from Wizards of the Coast.
    • User input errors (e.g., incorrect ability scores, level, or class selections).
  • Always double-check with your Dungeon Master before finalizing your character’s hit points or any stats. This tool is a helpful starting point — not an authoritative rules reference.
