Playing Dungeons & Dragons (D&D) requires a combination of strategy, skill, and a bit of luck. Combat encounters can often be unpredictable, leaving players wondering whether their attack will land or how much damage they can realistically deal. The D&D Combat Calculator is a user-friendly tool designed to make these calculations fast, accurate, and effortless. By using this calculator, players can quickly determine their chance to hit enemies and the expected damage output for multiple attacks, enhancing strategic gameplay and reducing guesswork.

Combat Results
Whether you’re a new player learning combat mechanics or a seasoned adventurer optimizing your party’s efficiency, this tool provides reliable calculations to improve decision-making in any encounter.
What Is the D&D Combat Calculator?
The D&D Combat Calculator is an interactive online tool that calculates two essential elements of combat in Dungeons & Dragons:
- Chance to Hit (%) – The probability that your attack will successfully hit an enemy based on your attack bonus and the enemy’s Armor Class (AC).
- Expected Damage – The total damage you can anticipate over a series of attacks, considering your damage per hit and number of attacks.
By entering your attack bonus, enemy AC, damage per hit, and number of attacks, the calculator provides instant feedback. It’s particularly helpful for:
- Players looking to optimize attack strategies.
- Dungeon Masters balancing encounters.
- Game sessions where efficiency and quick decision-making matter.
How to Use the D&D Combat Calculator
Using this tool is simple and requires no prior technical knowledge. Follow these steps to get accurate combat results:
- Enter Player Attack Bonus
Input your character’s attack bonus. This is the modifier added to your d20 roll when attacking. - Enter Enemy Armor Class (AC)
Fill in the AC of the enemy you are attacking. Higher AC reduces the chance to hit. - Enter Damage per Hit
Enter the damage your attack deals on a successful hit. Include modifiers like strength, dexterity, or magical bonuses. - Enter Number of Attacks
Specify how many times your character will attack in the round. Some classes or spells allow multiple attacks per turn. - Click “Calculate”
The calculator instantly displays your chance to hit and expected damage based on your inputs. - View Results
- Chance to Hit (%): Probability your attack will succeed.
- Expected Damage: Average total damage across all attacks.
- Optional Actions
- Copy Results – Quickly copy calculations for notes, party planning, or sharing.
- Share Results – Send results to teammates or on forums for collaboration.
- Reset
Clear all inputs using the reset button to calculate a different scenario.
Practical Examples of Using the Calculator
Example 1: Fighter Attacking a Goblin
Suppose your level 5 fighter has an attack bonus of +7, and the goblin enemy has an AC of 15. Your weapon deals 1d8+3 damage, averaging 7.5 damage per hit, and you can attack two times per turn.
By entering:
- Attack Bonus: 7
- Enemy AC: 15
- Damage per Hit: 7.5
- Number of Attacks: 2
The calculator might show:
- Chance to Hit: 65%
- Expected Damage: 9.75
This allows the player to predict damage outcomes and adjust strategy, such as using buffs or advantage to improve the chance to hit.
Example 2: Wizard Casting Firebolt
A level 3 wizard with a +5 spell attack bonus casts Firebolt against an enemy with AC 16. The spell deals 1d10 damage, averaging 5.5 per hit, and the wizard can attack once per turn.
Inputting these values produces:
- Chance to Hit: 55%
- Expected Damage: 3.03
This quick calculation helps the wizard determine whether using Firebolt is efficient or if another tactic, like casting a spell with guaranteed effect, would be more effective.
