How to Use the HP Calculator

Learn how to calculate hit points for your D&D 5e characters with our comprehensive step-by-step guide.

Quick Start Guide

Our D&D 5e HP Calculator makes it easy to determine your character's hit points at any level. Follow these simple steps to get started:

Step 1: Select Your Class

Choose your character's class from the dropdown menu. Each class has a different hit die size that determines your base hit points.

Step 2: Enter Your Level

Input your character's current level (1-20). The calculator will automatically determine how many hit dice you have.

Step 3: Add Constitution Modifier

Enter your Constitution ability score modifier. This bonus is added to your hit points at every level.

Step 4: Choose Calculation Method

Select between "Average" (recommended) or "Roll" for hit point calculation. Average uses the standard D&D 5e rules.

Detailed Instructions

Understanding Hit Points in D&D 5e

Hit points represent your character's health and ability to withstand damage. They're calculated using your class's hit die, your Constitution modifier, and your character level.

Hit Die by Class

Constitution Modifier

Your Constitution modifier is calculated from your Constitution ability score:

Calculation Methods

Average Method (Recommended)

Uses the average value of your hit die plus Constitution modifier. This is the standard method used in D&D 5e:

  • d6: 4 hit points per level
  • d8: 5 hit points per level
  • d10: 6 hit points per level
  • d12: 7 hit points per level

Roll Method

Simulates rolling dice for each level. This method can result in higher or lower hit points depending on your rolls.

Calculation Examples

Example 1: Level 5 Fighter

Character Details:

  • Class: Fighter (d10 hit die)
  • Level: 5
  • Constitution: 16 (+3 modifier)
  • Method: Average

Calculation:

Level 1: 10 (max hit die) + 3 (Con mod) = 13 HP

Levels 2-5: 4 levels × (6 + 3) = 4 × 9 = 36 HP

Total: 13 + 36 = 49 HP

Example 2: Level 3 Wizard

Character Details:

  • Class: Wizard (d6 hit die)
  • Level: 3
  • Constitution: 14 (+2 modifier)
  • Method: Average

Calculation:

Level 1: 6 (max hit die) + 2 (Con mod) = 8 HP

Levels 2-3: 2 levels × (4 + 2) = 2 × 6 = 12 HP

Total: 8 + 12 = 20 HP

Tips and Best Practices

Character Creation Tips

Multiclassing Considerations

When multiclassing, you gain hit points based on the hit die of the class you're taking a level in. Our calculator currently handles single-class characters, but you can manually calculate multiclass hit points by adding the appropriate hit die for each level.

Important Note

Always consult your Dungeon Master for final hit point calculations, especially for multiclass characters or when using house rules.

Common Questions

Q: What if my Constitution modifier changes?

If your Constitution score increases (through ability score improvements or magic items), you gain additional hit points equal to your new modifier for each level you have. If it decreases, you lose hit points accordingly.

Q: How do temporary hit points work?

Temporary hit points are separate from your maximum hit points and are added on top. They don't stack with each other - you only keep the highest amount.

Q: What about the Tough feat?

The Tough feat gives you +2 hit points per level. You can add this manually to your calculated total if your character has this feat.
