Dnd 5e Health Calculator Increase Constitution

Reviewed by Calculator Editorial Team

In Dungeons & Dragons 5th Edition, your Constitution score determines your hit points. Increasing your Constitution can significantly boost your character's health. This calculator helps you determine exactly how much your hit points will increase when you raise your Constitution score.

How This Calculator Works

The calculator uses the standard D&D 5e hit point calculation formula, which is based on your character's level and Constitution modifier. When you increase your Constitution score, your Constitution modifier changes, which in turn affects your hit points.

The formula accounts for:

  • Your character's level
  • Your current Constitution score
  • Your target Constitution score
  • Your character's hit dice (d8 for most classes)

The calculator shows you the exact increase in hit points you'll gain from raising your Constitution score, as well as a comparison of your current and potential hit points.

The Formula

The D&D 5e hit point calculation formula is:

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

Where Constitution Modifier = (Constitution Score - 10) ÷ 2

When you increase your Constitution score, your Constitution modifier changes, which affects your total hit points. The calculator uses this formula to show you the exact increase in hit points you'll gain.

Worked Example

Let's say you're a level 5 fighter with a Constitution score of 14. Your current hit points are:

Hit Points = (8 × 5) + ((14 - 10) ÷ 2 × 5) = 40 + (2 × 5) = 40 + 10 = 50

If you increase your Constitution to 16, your new hit points would be:

Hit Points = (8 × 5) + ((16 - 10) ÷ 2 × 5) = 40 + (3 × 5) = 40 + 15 = 55

This means increasing your Constitution from 14 to 16 would increase your hit points by 5.

Constitution vs. Hit Points

The following table shows how Constitution scores translate to hit points at different character levels:

Level Constitution 10 Constitution 12 Constitution 14 Constitution 16 Constitution 18
1 8 + (0 × 1) = 8 8 + (1 × 1) = 9 8 + (2 × 1) = 10 8 + (3 × 1) = 11 8 + (4 × 1) = 12
5 40 + (0 × 5) = 40 40 + (1 × 5) = 45 40 + (2 × 5) = 50 40 + (3 × 5) = 55 40 + (4 × 5) = 60
10 80 + (0 × 10) = 80 80 + (1 × 10) = 90 80 + (2 × 10) = 100 80 + (3 × 10) = 110 80 + (4 × 10) = 120
15 120 + (0 × 15) = 120 120 + (1 × 15) = 135 120 + (2 × 15) = 150 120 + (3 × 15) = 165 120 + (4 × 15) = 180
20 160 + (0 × 20) = 160 160 + (1 × 20) = 180 160 + (2 × 20) = 200 160 + (3 × 20) = 220 160 + (4 × 20) = 240

This table shows that increasing your Constitution score provides a significant boost to your hit points, especially at higher levels.
