Pokémon Stat Calculator (Gen 3+)
Enter your Pokémon's level, nature, and stat values to calculate final in-battle stats for HP, Attack, Defense, Sp. Atk, Sp. Def, and Speed.
| Stat | Base Stat | IV (0-31) | EV (0-252) | Final Stat |
|---|---|---|---|---|
| HP | - | |||
| Attack | - | |||
| Defense | - | |||
| Sp. Atk | - | |||
| Sp. Def | - | |||
| Speed | - |
What this Pokémon stat calculator does
This calculator helps you compute the final stats of a Pokémon based on core inputs: base stats, IVs, EVs, level, and nature. Whether you're preparing a ranked team, building for in-game battles, or optimizing raid performance, seeing exact stat outcomes lets you make smarter choices.
Instead of guessing whether 244 Speed EVs is enough or whether a bulky spread survives a key hit, you can quickly test numbers and adjust in seconds.
How Pokémon stats are calculated
HP formula
For HP (except special edge cases like Shedinja), the game uses:
HP = floor(((2 × Base + IV + floor(EV / 4)) × Level) / 100) + Level + 10
Other stats formula (Attack, Defense, Sp. Atk, Sp. Def, Speed)
For non-HP stats, the game calculates:
Stat = floor((floor(((2 × Base + IV + floor(EV / 4)) × Level) / 100) + 5) × Nature)
- Nature multiplier is usually 1.1 (boosted stat), 0.9 (lowered stat), or 1.0 (neutral).
- Because of flooring, small EV changes may not increase a stat immediately.
Quick input guide
Base Stat
The species value (for example, Garchomp has base 130 Attack and base 102 Speed).
IVs (Individual Values)
Range from 0 to 31 per stat. Competitive builds generally aim for 31 in most stats, except certain trick-room or special optimization cases.
EVs (Effort Values)
Each stat can have up to 252 EVs, with a team-wide total cap of 510 EVs. Since EVs effectively work in groups of 4 for stat gains, 252 is typically used (not 255).
Nature
A nature boosts one stat and lowers another (except neutral natures). For example:
- Jolly: +Speed, -Sp. Atk
- Adamant: +Attack, -Sp. Atk
- Modest: +Sp. Atk, -Attack
Example build workflow
Suppose you're building a physical sweeper at level 50:
- Set level to 50
- Select Jolly if you need speed benchmarks
- Try EVs of 252 Attack / 252 Speed / 4 Sp. Def
- Check whether final Speed outspeeds the targets you care about
If you're one point short, test alternatives like changing nature, shifting EVs, or adjusting IV assumptions.
Common stat-building mistakes
- Ignoring EV total: You cannot exceed 510 EVs total.
- Wasting EVs: EV values not divisible by 4 often produce no immediate gain.
- Wrong nature choice: A mismatched nature can undermine your whole spread.
- No speed benchmarks: Speed tiers often decide matches; calculate them deliberately.
Tips for better optimization
1) Start with your role
Decide if your Pokémon is a wall, breaker, support, or cleaner. Stat priorities follow role.
2) Target specific benchmarks
Don't just max stats blindly. Aim for meaningful goals like surviving a known hit, outrunning a popular threat, or securing a KO range.
3) Recalculate after each tweak
Because of floor rounding, tiny changes can matter. This calculator makes repeated checks fast and reliable.
Final note
If you care about precision in team building, a stat calculator is essential. Use it during planning, test multiple EV spreads, and lock in the version that matches your strategy. Competitive consistency starts with accurate numbers.
