What is the EV budget and the 252 cap?

Since Generation 6 a Pokémon can hold at most 510 effort values total, and no single stat can exceed 252 EVs. That means a classic competitive spread is 252 plus 252 plus 6, covering two main stats and a leftover six.

What stat formula does this use?

It uses the standard Generation 3 and later formula. HP is floor((2 × Base + IV + floor(EV / 4)) × Level / 100) + Level + 10, and other stats use a similar form times the nature multiplier, plus 5.

How does nature affect the result?

A nature raises one stat by 10 percent and lowers another by 10 percent, applied as a 1.1 or 0.9 multiplier on the final non-HP stat. Choosing a nature that boosts your attacking stat is a free power gain.

Why does it only invest in two stats?

Spreading EVs thinly wastes them because every four EVs give just one stat point. Competitive builds maximise impact by dumping the full 252 into each of the two stats that matter most for the playstyle.

What playstyle should I pick?

Physical sweepers invest in Attack and Speed, special sweepers in Special Attack and Speed, and tanks in HP plus the relevant defence. Choose the one matching your Pokémon's role and movepool.

A Pokémon’s final stats come from a precise formula combining base stats, IVs, EVs, nature, and level. This optimizer spends your 510-point EV budget where it matters most for your chosen role, respecting the 252-per-stat cap, and shows the exact final stats you will get.

How it works

The Generation 3+ stat formulas are:

HP    = floor( (2 × Base + IV + floor(EV/4)) × Level / 100 ) + Level + 10
Other = floor( ( floor( (2 × Base + IV + floor(EV/4)) × Level / 100 ) + 5 ) × Nature )

Nature is 1.1 for the boosted stat, 0.9 for the hindered stat, and 1.0 otherwise. The optimizer pours 252 EVs into each of the two stats your playstyle prioritises and the leftover 6 into the third, staying within the 510 total cap.

Example and tips

A level-100 sweeper with 31 IVs everywhere, a base 130 Attack, and an Attack-boosting nature gains the full 1.1 multiplier on top of its 252 Attack EVs, turning a respectable stat into a game-ending one. Because every 4 EVs yield 1 point, never leave odd EVs stranded — the classic 252/252/6 split is mathematically efficient. Match your two invested stats to your Pokémon’s strongest base stats and best attacking category for the biggest payoff.
