How to Calculate Armor Class in D&D 5e
Armor Class (AC) in Dungeons & Dragons 5th edition (D&D 5e) serves as a crucial measure of a character's defense against attacks. The calculation of AC begins with a base of 10. To this base, various modifiers are added based on the character's attributes, armor, and other abilities.
Understanding Base AC and Modifiers
Add the Dexterity modifier to the base AC. If the Dexterity modifier is 2 or higher, start from 2; if below 2, use the actual Dexterity modifier. For characters such as Barbarians or Monks, additional modifiers like the Constitution and Wisdom modifiers respectively are included. For a Barbarian, add the Constitution modifier. For a Monk, add both the Wisdom and Constitution modifiers.
Influence of Armor and Abilities
Wearing armor directly enhances AC. Each type of armor provides a specific AC bonus. Similarly, shields incrementally increase AC. Natural armor also contributes to AC but is calculated differently, and does not count as wearing armor. Certain class features, racial traits, spells, and magic items also elevate a character's AC, providing broader avenues to boost defense capabilities.
To sum up, calculate your D&D 5e character's Armor Class by starting with a base of 10, adding the Dexterity modifier, and incorporating any relevant modifiers from your character’s class features, armor, or other special abilities. This method ensures your character is equipped for better defense against foes.
How to Calculate Armor Class in D&D 5e
Armor Class (AC) is a critical value in Dungeons and Dragons 5e, quantifying a character's ability to evade or withstand an attack. Understanding how to calculate AC allows players to optimize their character's defense capabilities.
Calculating Base AC Without Armor
For a character wearing no armor, start with a base AC of 10. Add the character's Dexterity modifier. For Barbarians, add the Constitution modifier. Monks should add both their Constitution and Wisdom modifiers to the base. The formula is as follows: AC = 10 + Dexterity Modifier (+ Constitution Modifier for Barbarians) (+ Wisdom Modifier for Monks).
AC with Natural Armor
Characters with natural armor, such as Tortles, calculate AC by starting with 10 and adding any natural armor bonuses. The Dexterity modifier also contributes unless otherwise specified. Natural armor does not count as wearing armor.
AC for Characters Wearing Armor
Different armor types affect how AC is calculated:
Shields can be used with armor and they provide an additional +2 to the base AC.
Improving your character's AC in D&D 5e can significantly enhance their survival on the battlefield by making them less vulnerable to enemy attacks. Mastery of AC calculations is essential for strategic gameplay.

Examples of Calculating Armor Class in D&D 5e
Example 1: Standard Leather Armor
A character wearing standard leather armor, which grants a base armor class of 11, and possessing a Dexterity modifier of +2, would calculate their armor class (AC) as follows: AC = 11 + 2 = 13. This calculation includes the base armor plus the Dexterity modifier.
Example 2: Full Plate Armor
For armor that provides more substantial protection, such as full plate armor, the calculation differs slightly as it doesn't incorporate the Dexterity modifier. Full plate armor alone sets the AC at 18. Therefore, regardless of the wearer’s Dexterity modifier, the AC remains: AC = 18.
Example 3: Mage with Mage Armor Spell
A mage casting the Mage Armor spell would set their base AC at 13. If they have a Dexterity modifier of +3, the total AC would be calculated as: AC = 13 + 3 = 16. This ensures that the mage combines both magical protection and agility to determine their defense capability.
Example 4: Shield Usage
When a warrior uses a shield along with their armor, it contributes an additional +2 to the AC. Suppose the warrior wears chain mail with a base AC of 16 and uses a shield; their total AC would be: AC = 16 + 2 = 18, significantly increasing their defensive stature.
Example 5: Unarmored Defense
Monks and Barbarians often use their physical prowess to calculate AC differently through Unarmored Defense. For instance, a monk with a Dexterity modifier of +3 and a Wisdom modifier of +2 calculates their AC as: AC = 10 + 3 + 2 = 15, representing their agile and insightful nature in defense.
