Click "Calculate" to see your results

The calculator will display your total hit points, hit dice progression, and other relevant health statistics.

Formula Used

The calculator uses the standard D&D 5e hit point calculation formula:

Hit Points = (Hit Dice × Level) + (Constitution Modifier × Level)

Where:

Hit Dice = The type of dice used for hit points (d4, d6, d8, d10, d12)
Level = Character level or monster challenge rating
Constitution Modifier = Character's Constitution modifier (or 0 for monsters)

For example, a level 5 Fighter with a Constitution modifier of +3 and d10 hit dice would have:

Hit Points = (10 × 5) + (3 × 5) = 50 + 15 = 65

Worked Example

Let's calculate the hit points for a level 3 Barbarian with a Constitution modifier of +2 and d12 hit dice:

Hit Dice = d12 (12)
Level = 3
Constitution Modifier = +2

Using the formula:

Hit Points = (12 × 3) + (2 × 3) = 36 + 6 = 42

So the Barbarian would have 42 hit points at level 3.

Here's a comparison table showing hit point progression for this character:

Level	Hit Dice Roll	Constitution Bonus	Total Hit Points
1	12	2	14
2	24	4	28
3	36	6	42
4	48	8	56
5	60	10	70

Frequently Asked Questions

What is the difference between hit points and hit dice?

Hit points represent a character's or monster's current health. Hit dice determine how many hit points a character gains when they level up or when they use certain features like a barbarian's Rage or a cleric's Channel Divinity.

How do I calculate hit points for a monster?

For monsters, use the same formula but set the Constitution modifier to 0. The hit dice type and challenge rating (converted to an equivalent character level) determine the monster's hit points.

Can I use this calculator for homebrew characters?

Yes, you can use this calculator for homebrew characters as long as you adjust the hit dice and Constitution modifier values to match your homebrew rules.
