D&D 5e Hit Point Calculator

Estimate maximum, current, and temporary hit points. Compare fixed gains, rolls, feats, and multiclass choices. Keep combat tracking simple for every adventuring party session.

Calculator Inputs

Formula Used

Constitution modifier: floor((Constitution score - 10) / 2), unless the custom modifier option is selected.

First level: starting hit die maximum + Constitution modifier.

Later fixed level gain: floor(hit die / 2) + 1 + Constitution modifier.

Later average level gain: ((hit die + 1) / 2) + Constitution modifier.

Maximum hit points: base hit points + Tough feat bonus + per-level bonuses + flat maximum bonuses.

Current hit points: maximum hit points - damage taken. Temporary hit points are added only to the effective pool.

Why Hit Points Matter

Hit points show how long a character can stay active before danger becomes severe. They are not only meat or wounds. They also represent grit, luck, stamina, timing, and battle awareness. A careful hit point estimate helps a player judge risk before a dungeon, boss fight, or long travel day.

This calculator focuses on common fifth edition character building. It starts with a maximum first hit die. It then adds later level gains from fixed values, average values, or your rolled total. Constitution is applied across levels, because a better modifier changes maximum hit points for every level already earned.

Advanced Options

Many tables use extra features. The Tough feat adds two hit points per level. Some species or class features add one point per level. Spells, boons, and house rewards may add flat maximum bonuses. Temporary hit points are kept separate, because they protect the character but do not increase the maximum score.

Multiclass characters need special care. The first character level uses the starting class hit die at its maximum value. Later levels use the hit die tied to each class level. This file lets you enter up to three class groups, so mixed builds remain easy to check.

Using Results During Play

Maximum hit points help with leveling, encounter planning, and character sheet updates. Current hit points show the remaining health after damage. The effective pool adds temporary hit points, which is useful when planning whether to stand, retreat, or spend resources.

The short rest estimate is only a planning guide. Actual healing depends on which hit dice are spent and how each die rolls. Use it before resting to compare options. Save your result as a CSV for records, or export a simple PDF for a printed table note.

Good hit point tracking keeps combat moving. It also reduces mistakes after level ups, ability score changes, feats, and table rulings. Before the session, share the numbers with the game master. This helps everyone follow the same method. It also makes later corrections easier when equipment, spells, or story rewards change. Keep notes for each level, especially when rolled gains are used at your table. Records also prevent disputes during tense encounters later.

FAQs

Does the calculator support multiclass characters?

Yes. Enter levels and hit dice for up to three class groups. The first group is treated as the starting class, so its first level uses the maximum hit die value.

How is the Constitution modifier calculated?

It uses floor((Constitution score - 10) / 2). You can also enable the custom modifier field when your table uses a special rule or temporary effect.

What does fixed level gain mean?

Fixed gain uses the usual table value for each hit die. It equals floor(hit die / 2) + 1 before adding the Constitution modifier.

Can I use rolled hit points?

Yes. Choose the custom rolled total method. Enter the total of all rolled hit die gains after level one, excluding Constitution bonuses.

Are temporary hit points added to maximum hit points?

No. Temporary hit points are shown as part of the effective pool. They protect the character but do not raise the maximum hit point score.

How does the Tough feat option work?

The Tough feat option adds two hit points per character level. It scales automatically with the total level entered in the class groups.

Why is there a minimum one option?

Some tables enforce a minimum gain of one hit point per level. Enable this option when low Constitution would reduce a level gain below one.

Can I download the result?

Yes. Use the CSV button for spreadsheet records. Use the PDF button for a simple printable summary of the current calculation.
