1. What is the Spell Slot Calculator?

The Spell Slot Calculator determines how many spells of each level a character can cast per day in Dungeons & Dragons 5th Edition, based on their class and level.

2. How Does the Calculator Work?

The calculator uses the official D&D 5e rules for spell slots:

Where:

• Class — Determines spell progression (full caster, half caster, or warlock)
• Level — Character level in the spellcasting class (1-20)

3. Spellcasting Classes

Full Casters (Bard, Cleric, Druid, Sorcerer, Wizard): Gain access to higher spell levels faster and more spell slots overall.

Half Casters (Paladin, Ranger): Gain spell slots at half the rate of full casters.

Warlocks: Have unique Pact Magic with fewer but more powerful spell slots that recharge on short rests.

4. Using the Calculator

Steps: Select your character's spellcasting class and enter their level in that class (1-20). The calculator will display your available spell slots by level.

5. Frequently Asked Questions (FAQ)

Q1: What about multiclassing?
A: This calculator shows slots for a single class. Multiclassing uses different rules found in the Player's Handbook.

Q2: Why are warlock slots different?
A: Warlocks use Pact Magic - their slots are always cast at the highest available level and recharge on short rests.

Q3: Do cantrips use spell slots?
A: No, cantrips can be cast at will without expending spell slots.

Q4: What if my class isn't listed?
A: Only classes with spellcasting are included. Some subclasses gain spellcasting (like Arcane Trickster) - use their base class.

Q5: How do magic items affect slots?
A: This calculator shows base slots only. Magic items may grant additional slots.
