Calculator Inputs

Formula Used

The calculator uses effective caster level for normal spell slots.

Effective caster level = full caster levels + half caster levels + third caster levels + custom adjustment.

Full caster levels include bard, cleric, druid, sorcerer, and wizard. Artificer is rounded up as half. Paladin and ranger are rounded down as half. Arcane trickster and eldritch knight are rounded down as one third.

Remaining slots = total slots - used slots.

Ability modifier = floor((ability score - 10) / 2).

Spell save DC = 8 + proficiency bonus + ability modifier.

Spell attack bonus = proficiency bonus + ability modifier.

Warlock pact magic is calculated separately. Pact slots do not merge with normal multiclass slots.

Spell Slot Planning for 5e Characters

A spell slot calculator helps players plan each adventuring day. It is useful for single class casters. It is also helpful for complex multiclass builds. Fifth edition characters can gain slots from full casters, half casters, third casters, and pact magic. The final table can be hard to check during play. This tool turns those moving parts into a clear resource sheet.

Why Slot Tracking Matters

Spell slots are limited. A powerful spell used too early can change a later encounter. A healer may need to save key slots. A wizard may want higher slots for control spells. A paladin may reserve slots for smites. Good tracking supports better choices. It also prevents mistakes when different class rules combine.

Multiclass Caster Support

The calculator uses effective caster level. Bard, cleric, druid, sorcerer, and wizard levels count fully. Paladin and ranger levels count as half. Artificer levels round up as half. Arcane trickster and eldritch knight levels count as one third. The final effective level maps to the standard multiclass spell slot table. Warlock pact magic is shown separately. Pact slots recharge differently, so they should not be merged with normal slots.

Advanced Table Use

Enter the levels for each class. Add the number of slots already spent at each spell level. The result shows total slots, used slots, and remaining slots. It also estimates proficiency, spell save DC, and spell attack bonus from character level and casting ability. These values help players prepare a quick combat reference.

Campaign Benefits

Dungeon Masters can use the output to review party resources. Players can export results before a session. A CSV file helps with spreadsheets. The PDF option creates a printable sheet. The example table gives a quick comparison for common builds. This makes the page useful for planning, not just math.

Use the calculator before rests, boss fights, and travel days. Update used slots after major scenes. Keep pact slots separate. Review remaining high level slots before risky choices. A clean plan makes spellcasting faster, fairer, and easier for everyone at the table. It also helps new players understand why caster level differs from character level during multiclass planning and table review after every rest phase.
