Frequently Asked Questions
How does this calculator compare to Pokémon Showdown?▼
This calculator uses the same @smogon/calc engine as Pokémon Showdown, ensuring 100% accurate damage calculations. Results match exactly what you'd see in competitive play. The main advantage here is the user-friendly interface with automatic stat calculation from base stats, EVs, and IVs.
What is STAB and how does it work?▼
STAB stands for "Same Type Attack Bonus". When a Pokémon uses a move that matches its own type, the move's damage is multiplied by 1.5×. For example, a Water-type Pokémon using Surf gets STAB, but using Thunderbolt does not. With Terastallization in Gen 9, if you Tera into the same type as your move, you get a 2× STAB instead!
How do I calculate damage for dual-type Pokémon?▼
For dual-type Pokémon, type effectiveness is calculated by multiplying both types' effectiveness. For example, Electric vs. Water/Flying is 2× (vs Water) × 2× (vs Flying) = 4× super effective damage. This calculator handles all type matchups automatically.
What's the difference between physical and special moves?▼
Physical moves use the attacker's Attack stat and the defender's Defense stat. Special moves use Sp. Attack and Sp. Defense instead. Examples: Earthquake (Physical), Thunderbolt (Special). The calculator automatically determines this from the move you enter.
How do EVs and IVs affect damage?▼
IVs (Individual Values) range from 0-31 and provide small stat boosts. EVs (Effort Values) provide larger boosts - 4 EVs = 1 stat point at level 50. A Pokémon can have up to 510 total EVs with a max of 252 per stat. This calculator shows you the exact final stats after applying IVs, EVs, Nature, and level.
What does the damage range mean?▼
Pokémon damage has a random factor (85%-100% of the calculated damage). The calculator shows both minimum and maximum possible damage. This is why the same move can deal slightly different damage each time you use it in-game.
Can I use this for competitive VGC battles?▼
Yes! This calculator supports all battle modifiers used in VGC (Video Game Championships) including weather, terrain, screens, abilities, items, and Terastallization. It's perfect for team building, damage roll planning, and speed tier optimization.
How accurate is this Pokémon damage calculator?▼
This calculator uses the official Pokémon damage formula from Generation 8/9 via the @smogon/calc library. The results match exactly what you'll see in Pokémon Sword/Shield, Scarlet/Violet, and competitive formats like VGC and Smogon. It's maintained by the competitive Pokémon community and updated for each generation.
