D&D Spell Slot Calculator
Spell slots for any class or multiclass in D&D 5e: full, half and third casters on the multiclass table, Warlock Pact Magic kept separate, 2014 vs 2024 compared.
How the D&D Spell Slot Calculator works
Work out a D&D 5e character's spell slots from their class levels, for a single class or a multiclass build. It uses the multiclass spellcaster rules for full, half and third casters, shows Warlock Pact Magic separately, and points out where the 2014 and 2024 rules give different slots.
- Choose 2024 rules or 2014 rules.
- Pick a class and set its level. For a multiclass character, use Add a class for each other class, up to level 20 in total.
- Read the spell slots for each spell level, and how much each class adds to your spellcaster level.
- Warlock levels appear in their own Pact Magic box. The box for the other rules version shows whether it would change your slots.
- With one class, open the full table below the calculator to see that class's slots at every level.
How multiclass spell slots are worked out
If only one of your classes has the Spellcasting feature, you use that class's own table, even if you have levels in other classes. A Paladin 5 / Fighter 3 has a level 5 Paladin's slots.
With Spellcasting from two or more classes, you add up a spellcaster level and look it up on the multiclass spellcaster table: all your Bard, Cleric, Druid, Sorcerer and Wizard levels, half your Paladin and Ranger levels, half your Artificer levels rounded up, and a third of your Fighter or Rogue levels if you're an Eldritch Knight or Arcane Trickster, rounded down. The calculator rounds each class on its own.
This tells you how many slots you have, not which spells you know. You prepare spells for each class separately, but can cast any of them with a slot of the right level.
2014 vs 2024 differences
The multiclass spellcaster table is the same in both versions. Two things change:
Paladin and Ranger levels are halved and rounded down in 2014, but rounded up in 2024. A Paladin 5 / Sorcerer 3 is a 5th-level spellcaster in 2014 (2 + 3) and a 6th-level spellcaster in 2024 (3 + 3), which adds a third 3rd-level slot.
Paladins and Rangers get their first spell slots at level 1 in 2024, but not until level 2 in 2014. So a Paladin 1 / Wizard 1 counts as a multiclass caster in 2024, while in 2014 only the Wizard level gives slots.
Warlock Pact Magic
Warlock slots come from Pact Magic, not Spellcasting, so warlock levels never add to the multiclass table. The tool shows them separately: 1 slot at level 1, 2 slots from level 2, 3 from level 11 and 4 from level 17, with every slot at the same spell level (up to 5th from warlock level 9). Pact Magic slots come back on a short rest; you can spend either kind of slot on spells from any of your classes.
Sources
The multiclass table, the Paladin, Ranger and Warlock tables and the multiclass rules are from the System Reference Documents 5.1 (2014) and 5.2 (2024). Artificer, Eldritch Knight and Arcane Trickster aren't in either SRD; their rules come from the published books.
Frequently asked questions
How do spell slots work when you multiclass?
Add your full-caster levels, half your Paladin and Ranger levels, half your Artificer levels (rounded up) and a third of your Eldritch Knight or Arcane Trickster levels, then read that total on the multiclass spellcaster table. If only one class has Spellcasting, just use that class's own table.
Do Paladin and Ranger round up or down when multiclassing?
Down in the 2014 rules and up in the 2024 rules. For example, Paladin 3 counts as 1 spellcaster level in 2014 and 2 in 2024. The calculator uses whichever version you pick and shows the other version's slots if they differ.
Do Warlock spell slots stack with other classes?
No. Warlock levels don't count toward the multiclass spellcaster level, and Pact Magic slots are tracked separately. A Warlock 2 / Sorcerer 5 has a level 5 Sorcerer's slots plus two 1st-level Pact Magic slots. You can use either kind of slot to cast spells from either class.
How many spell slots does a level 5 wizard have?
Four 1st-level, three 2nd-level and two 3rd-level slots. Full casters like the Bard, Cleric, Druid, Sorcerer and Wizard use the same slot progression as the multiclass table, so their slots match a spellcaster level equal to their class level.
Can multiclassing give me higher-level slots than spells I know?
Yes. A Paladin 10 / Wizard 10 is a 15th-level spellcaster with slots up to 8th level, but a level 10 Wizard only has spells up to 5th level. You can still use the higher slots to cast your spells at a higher level, which makes many of them stronger.
Why does Eldritch Knight 3 alone have more slots than the multiclass math suggests?
Because a single spellcasting class uses its own table. An Eldritch Knight's own table gives two 1st-level slots at Fighter level 3 and three at level 4, but when multiclassing with another caster, only a third of Fighter levels, rounded down, count toward the combined table.
