You should usually evolve Pikachu once it has learned the key moves you want (often around level 26–32 in most classic games), then use a Thunder Stone to get Raichu.

Quick Scoop

“When should I evolve Pikachu?” is basically asking: “Do I want better stats now, or more moves later?”

In most mainline games, Pikachu evolves into Raichu with a Thunder Stone at any level, so the real decision is about moves versus power.

How Pikachu Evolves

  • Pikachu evolves into Raichu when you use a Thunder Stone.
  • Raichu generally does not learn new moves by level-up , so you want Pikachu to learn its good moves first.
  • Because of that, people usually delay evolution until certain move levels.

Common “Best Time” Breakpoints

Different players and forum discussions suggest these key levels:

  • Level 26–29
    • Pikachu typically learns Thunderbolt around here in many older games.
* Lots of players recommend evolving right after Thunderbolt because it’s a strong, accurate Electric STAB move.
  • Around level 32
    • Guides often say “around level 32” so Pikachu can learn all its main level-up moves, including Discharge in some gens.
* After that, you don’t lose much by evolving.
  • Much later (level 40–50+)
    • Some forum players keep Pikachu to level 45–50+ so it builds speed and picks up as many moves as possible, then evolve to Raichu for endgame.
* This is more of a personal style choice than a strict optimization.

It Depends On Your Goal

1. Fast, stronger team now

If you want stronger stats quickly :

  1. Make sure Pikachu knows Thunderbolt (via level, TM, or move relearner).
  1. Use a Thunder Stone right after that (often late 20s).

Raichu gives you better overall stats immediately, which helps if you’re struggling with story battles or gyms.

2. Maximizing Pikachu’s moves

If you care about learning moves naturally :

  • Keep Pikachu until it learns the last key moves you care about (commonly around level 32 for Discharge in some games).
  • Then evolve with a Thunder Stone so you don’t miss those level-up moves.

Some players even delay to level 40+ to grab moves like Thunder, then evolve; this is more “completionist” than necessary for casual play.

3. Keeping Pikachu forever

Some trainers just love Pikachu and never evolve it:

  • With a Light Ball , Pikachu’s offensive power is boosted so much that it can rival or even surpass Raichu in some contexts.
  • Forums mention this as a legit strategy if you want to use Pikachu itself as your main Electric attacker.

Forum-Style Take (What people actually say)

From fan Q&A sites and threads:

  • Some say: “Evolve immediately or at 26; Thunderbolt can be relearned or taught by TM anyway.”
  • Others insist: “Wait until at least 28–32 so Pikachu learns its full move set, then evolve.”
  • A few: “I kept mine to level 50, then evolved—now my Raichu is a monster.”

So the most common middle-ground answer across guides and discussions is:

Let Pikachu learn Thunderbolt (usually mid/late 20s) or up to around level 32, then evolve with a Thunder Stone.

Simple Rule You Can Follow

  • Story / casual play:
    • Evolve Pikachu right after it learns Thunderbolt or around level 28–32.
  • You love Pikachu itself:
    • Consider never evolving, and use a Light Ball if you can get it.
  • You don’t care about moves / using TMs:
    • You can evolve as soon as you get a Thunder Stone, since Raichu can learn important moves from TMs or move relearner in many games.

TL;DR: For most players asking “when should I evolve Pikachu,” the practical sweet spot is: let Pikachu learn Thunderbolt (mid/late 20s) or Discharge (around 32 if available), then evolve with a Thunder Stone for a strong Raichu that isn’t missing key moves.
