Surviving the Dungeon: The D&D 5e Hit Point Guide

In Dungeons & Dragons, your Hit Points (HP) are the only thing standing between your glorious hero and a dirt nap in a forgotten tomb. Calculating HP correctly is vital for game balance. If your HP is too low, you're a liability to the party; if it's too high (by mistake), you might trivialize combat encounters. Our 5e HP Calculator ensures your math is perfect every time you level up.

How Hit Points Work in 5e

Your Total HP is largely determined by three factors: your Class Hit Die, your Constitution Modifier, and your Level.

1. Hit Dice by Class:
Every class has a specific die representing its ruggedness.

d6: Sorcerer, Wizard (The squishies)
d8: Artificer, Bard, Cleric, Druid, Monk, Rogue, Warlock (The mid-range)
d10: Fighter, Paladin, Ranger (The warriors)
d12: Barbarian (The meat shield)

Calculating HP at Level 1

At 1st Level, you don't roll. You get the Maximum amount on your Hit Die + your Constitution Modifier.
Example: A Level 1 Barbarian (d12) with a +3 CON modifier starts with:
12 + 3 = 15 HP.

Calculating HP at Higher Levels

When you level up, you have two choices (check with your DM):

Option A: Taking the Average (Fixed)
This is the safe, consistent route. The "average" in D&D is rounded up.
d6 Avg = 4
d8 Avg = 5
d10 Avg = 6
d12 Avg = 7
Formula: (Average Die Roll + CON Mod) per level.

Option B: Rolling for HP
You roll your class Hit Die and add your CON modifier to the result. This is risky! You could roll a 1, resulting in minimal HP gain, or you could roll a 12.

Our calculator uses the Fixed/Average method, as it is the standard for Adventurers League and most organized play.

Constitution Changes

If your Constitution score increases (e.g., at level 4 or 8 via Ability Score Improvement), your HP increases retroactively for every level you have!
If you are level 5 and your CON Mod goes from +2 to +3, you instantly gain 5 HP (1 for each level). Don't forget this ruleâ€”it can save your life.

Special Traits: Tough Feat & Hill Dwarf

Certain builds get extra HP.
Tough Feat: You gain +2 HP for every level you have.
Hill Dwarf: Their Dwarven Toughness grants +1 HP per level.
Draconic Sorcerer: Grants +1 HP per level due to Draconic Resilience.
These bonuses stack! A Hill Dwarf Draconic Sorcerer with the Tough feat would be incredibly tanky for a spellcaster.

Why Calculation Matters

A Wizard with 10 Con at level 5 typically has roughly 22 HP. A Barbarian with 16 Con at level 5 has roughly 55 HP. Knowing these thresholds helps healers prioritize targets and helps players know when to retreat. Use this tool to double-check your character sheet math and keep the adventure going!
