Pokemon Type Calculator

Pokemon Type Calculator is an essential tool that instantly determines damage multipliers and type effectiveness for any attacking move against defending Pokemon types. This calculator eliminates the need to memorize 324 different type matchups by providing immediate results for all 18 Pokemon types and their combinations. Competitive battlers, casual players, raid coordinators, and team builders rely on this tool to optimize strategies, exploit weaknesses, and build balanced teams with comprehensive type coverage.

How to Use the Pokemon Type Calculator

Follow these five steps to calculate type effectiveness and damage multipliers for any battle scenario:

1. Gather Your Input Data: Identify the attacking move's type and the defending Pokemon's type(s). You'll need to know if the defending Pokemon has one type (like Charizard being Fire/Flying) or two types. This information is found in your Pokedex, on the Pokemon's stat screen, or in any Pokemon database. Note that some Pokemon change types through abilities like Protean or forme changes.
2. Enter Primary Value: Select the attacking move's type from the dropdown menu containing all 18 types: Normal, Fire, Water, Electric, Grass, Ice, Fighting, Poison, Ground, Flying, Psychic, Bug, Rock, Ghost, Dragon, Dark, Steel, and Fairy. Ensure you're selecting the move's type, not the attacking Pokemon's type, as these can differ (a Water-type Pokemon can use Ice-type moves).
3. Configure Additional Parameters: Select the defending Pokemon's primary type and secondary type (if applicable). For single-type Pokemon like Pikachu (Electric only), leave the secondary type field blank or set to 'None'. For dual-type Pokemon like Gyarados (Water/Flying), both type fields must be filled. The calculator multiplies effectiveness values when dual types are present.
4. Interpret Your Results: The calculator displays the final damage multiplier: 0x (immune), 0.25x (doubly resistant), 0.5x (resistant), 1x (neutral), 2x (super effective), or 4x (doubly super effective). Values above 1x indicate the attack deals extra damage, while values below 1x indicate reduced damage. A 0x result means the attack has no effect and deals zero damage regardless of stats.
5. Apply Results to Your Project: Use these multipliers to build competitive teams with optimal type coverage, identify your Pokemon's weaknesses to prepare defensive strategies, and select moves that maximize damage output during battles. Consider that a 4x weakness can be exploited even by weaker opponents, while 0.25x resistances create excellent defensive walls. Factor these matchups into team composition for gym battles, raids, and PvP competitions.

Calculating Damage Against Dual-Type Pokemon

Suppose you're planning a competitive battle and need to determine if your Raichu's Thunderbolt will be effective against an opponent's Swampert (Water/Ground dual-type):

• The Input: Attacking move type is Electric (Thunderbolt), defending Pokemon is Water/Ground type (Swampert). Water-type takes 2x damage from Electric moves, but Ground-type is immune (0x) to Electric moves.
• The Calculation: Multiply the effectiveness values for each type: Water effectiveness (2x) × Ground effectiveness (0x) = 0x final multiplier. The Ground-type immunity completely negates the Water-type weakness.
• The Result: The final multiplier is 0x, meaning Thunderbolt will deal absolutely no damage to Swampert regardless of Raichu's Special Attack stat or Swampert's Special Defense stat. The attack will display "It doesn't affect the foe's Swampert" in battle.
• The Application: You should immediately switch to a different Pokemon or move. Raichu should instead use Grass Knot (4x effective against Swampert's Water/Ground typing) if available, or switch to a Grass-type Pokemon like Venusaur to exploit Swampert's quadruple weakness to Grass-type moves.

Expert Tips & Key Considerations

• Prioritize Coverage Moves: Build movesets that cover your Pokemon's weaknesses and hit common threats super effectively. A well-rounded team should collectively have super effective options against all 18 types, minimizing situations where you're forced to use resisted or ineffective moves.
• Identify Quadruple Weaknesses: Pokemon with 4x weaknesses (like Tyranitar's Fighting weakness or Scizor's Fire weakness) require careful team support. Always have a counter-strategy ready, such as a teammate that resists the 4x weakness type and can safely switch in to absorb hits.
• Account for Ability Modifications: Remember that abilities like Levitate, Thick Fat, Sap Sipper, and Water Absorb can completely change type matchups. A Ground-type move shows 2x against Electric-types in this calculator, but will deal 0x damage to an Electric-type with Levitate like Eelektross.
• Consider STAB Bonuses: While this calculator shows type effectiveness multipliers, remember that Same Type Attack Bonus (STAB) adds an additional 1.5x multiplier when a Pokemon uses a move matching its own type. A 2x super effective STAB move actually deals 3x damage (2x × 1.5x).
• Plan for Tera Type Changes: In Generation IX games with Terastallization, Pokemon can temporarily change their type, completely altering matchup calculations. Always prepare backup strategies since a predicted 4x weakness can become a resistance after Terastallization transforms the Pokemon's defensive typing.
