Persona 5 Persona Fusion Formula:

Base Fusion Level ($$BFL$$):

$$BFL = \frac{\text{Persona 1 Level} + \text{Persona 2 Level}}{2}$$

Final Target Level ($$TL$$):

$$TL = \text{round}(BFL) + \text{Arcana Rank Bonus}$$

Variables:

  • Persona 1 Level (P1L): The level of the first persona used in the fusion.
  • Persona 2 Level (P2L): The level of the second persona used in the fusion.
  • Arcana Rank (AR): The Confidant Rank bonus applied to the fusion. This value is typically 0-10, corresponding to your Social Link rank with the associated Arcana.
  • Target/Result Level (TL): The base level of the resulting persona before any level-up or skill inheritance.

What is the Persona 5 Persona Fusion Calculator?

Persona fusion is the core mechanic for creating stronger Personas in the *Persona* series. In *Persona 5*, fusion success is highly dependent on the average level of the input Personas and the associated Arcana bonus from your Confidant Rank. Using an optimal fusion path is crucial for minimizing grinding and maximizing efficiency.

This calculator simplifies the reverse-engineering process. Unlike a forward-only calculator, this tool allows you to specify the *desired* Target Level (TL) and the Arcana Rank (AR) to determine exactly what levels (P1L or P2L) your input Personas need to be. This is especially useful for players aiming for specific endgame Personas.

How to Calculate Persona Fusion Level (Example):

  1. Determine Input Levels: You are fusing an input Persona at Level 50 (P1L) and another at Level 60 (P2L).
  2. Find Arcana Bonus: Your corresponding Confidant Rank is 7, giving an Arcana Rank Bonus (AR) of 7.
  3. Calculate Base Fusion Level (BFL): $$(50 + 60) / 2 = 110 / 2 = 55$$
  4. Determine Final Target Level (TL): $$TL = \text{round}(55) + 7 = 55 + 7 = 62$$
  5. The Result: The resulting Persona will have a Base Level of 62 (which can be further boosted by the “Strengthen Persona” mechanic).
