Understanding This Calculator
Every Pokémon stat is built from four ingredients: the species’ base stat, an individual value (IV) between 0-31 that’s fixed per Pokémon, effort values (EVs) earned through battling up to 252 per stat, and the Pokémon’s level. Non-HP stats get one more multiplier from the Pokémon’s nature.
HP uses a slightly different formula than the other five stats because it also adds the Pokémon’s level directly plus a flat +10, reflecting how HP scales differently from Attack, Defense, Speed, and the Special stats.
- Base species’ base stat
- IV individual value, 0-31
- EV effort value, 0-252
- Nature 1.1 beneficial, 1.0 neutral, 0.9 hindering
This calculator implements the publicly documented Gen III+ stat formulas (widely published on community wikis); it performs only this factual math and does not reproduce any game text, art, or branding.
Frequently Asked Questions
Why doesn’t nature affect HP?
Nature multipliers in the official games only ever apply to Attack, Defense, Special Attack, Special Defense, and Speed — HP is deliberately excluded from every nature’s boosted or lowered stat pair.
How much do EVs actually add to a stat?
Every 4 EVs invested adds roughly 1 point to a stat at level 100 (less at lower levels, due to the floor(EV/4) term and the level scaling), which is why competitive players typically invest EVs in blocks of 4.
