Pokémon Type Effectiveness Calculator
Select the attacking move’s type and the defending Pokémon’s type(s) to determine the damage multiplier.
Choose the type of the move being used.
The primary type of the defending Pokémon.
Select if the defending Pokémon has a secondary type.
Calculated Type Effectiveness
Move Type: Normal
Defender Type 1: Normal (Effectiveness: 1x)
Defender Type 2: None (Effectiveness: 1x)
Total Multiplier: 1x
The calculator determines the final damage multiplier by first finding the effectiveness of the Attacking Move Type against the Defending Pokémon’s Type 1. If the defending Pokémon has a Type 2, it then finds the effectiveness against that type as well. These individual effectiveness values are then multiplied together to get the Total Multiplier. For example, if a Fire move is 2x effective against Grass (Type 1) and 0.5x effective against Rock (Type 2), the total effectiveness is 2 * 0.5 = 1x (Neutral).

What is a Pokémon Type Calculator?
A Pokémon Type Calculator is an essential tool for any Pokémon trainer, whether you’re a casual player or a competitive battler. It helps you quickly determine the effectiveness of an attacking move’s type against a defending Pokémon’s type(s). In the world of Pokémon, every move and every Pokémon has one or two types (e.g., Fire, Water, Grass, Electric). These types interact in a rock-paper-scissors fashion, dictating how much damage a move will inflict.
This calculator simplifies complex type matchups, providing an instant damage multiplier (e.g., 2x for “Super Effective,” 0.5x for “Not Very Effective,” or 0x for “Immune”). Understanding these interactions is fundamental to developing effective battle strategies, choosing the right Pokémon for your team, and predicting opponent moves.
Who Should Use a Pokémon Type Calculator?
- New Players: To quickly learn and internalize the vast type chart without memorizing every single interaction.
- Competitive Battlers: To fine-tune team compositions, plan switch-ins, and ensure optimal move coverage against common threats.
- Casual Players: To make informed decisions during in-game battles, gym challenges, or against powerful wild Pokémon.
- Team Builders: To identify potential weaknesses in their team’s type coverage and adjust accordingly.
- Content Creators: To verify type matchups for guides, videos, or articles.
Common Misconceptions About Pokémon Type Effectiveness
- “STAB (Same Type Attack Bonus) is part of type effectiveness”: While STAB (a 1.5x damage bonus for moves matching the user’s type) is crucial for damage calculation, it’s a separate multiplier from type effectiveness. The Pokémon Type Calculator focuses solely on the type interaction multiplier.
- “Dual-type Pokémon are always weaker/stronger”: Dual types introduce more complex interactions, sometimes leading to double weaknesses (4x damage) or double resistances (0.25x damage), but also offering more neutral matchups. It’s not inherently better or worse, just different.
- “All moves of a certain type are equally effective”: Type effectiveness only applies to the *type* of the move, not its base power or other effects. A weak Fire move will still be 2x effective against Grass, but might do less damage than a strong neutral move.
Pokémon Type Calculator Formula and Mathematical Explanation
The core of the Pokémon Type Calculator lies in a straightforward multiplication of effectiveness values. Each type interaction (Attacking Move Type vs. Defending Pokémon Type) results in a specific multiplier: 2x (Super Effective), 1x (Neutral), 0.5x (Not Very Effective), or 0x (Immune).
Step-by-Step Derivation
- Identify Attacking Move Type (AMT): This is the type of the move being used (e.g., Fire, Water, Grass).
- Identify Defending Pokémon Type 1 (DPT1): This is the primary type of the Pokémon receiving the attack.
- Identify Defending Pokémon Type 2 (DPT2): If the defending Pokémon has a secondary type, this is it. If not, it’s considered “None.”
- Calculate Effectiveness 1 (Eff1): Determine the multiplier of AMT against DPT1. This is looked up in the standard Pokémon type chart.
- Calculate Effectiveness 2 (Eff2): If DPT2 is present, determine the multiplier of AMT against DPT2. If DPT2 is “None,” Eff2 is 1x.
- Calculate Total Multiplier (TM): Multiply Eff1 by Eff2.
The formula is simply:
Total Multiplier = Effectiveness(Attacking Move Type vs. Defending Type 1) × Effectiveness(Attacking Move Type vs. Defending Type 2)
Variable Explanations
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Attacking Move Type (AMT) | The elemental type of the offensive move. | Pokémon Type (e.g., Fire, Water) | 18 possible types |
| Defending Pokémon Type 1 (DPT1) | The primary elemental type of the Pokémon receiving the attack. | Pokémon Type (e.g., Grass, Flying) | 18 possible types |
| Defending Pokémon Type 2 (DPT2) | The secondary elemental type of the Pokémon receiving the attack (optional). | Pokémon Type (e.g., Poison, Dragon) or “None” | 18 possible types + “None” |
| Effectiveness 1 (Eff1) | Damage multiplier from AMT vs. DPT1. | x (multiplier) | 0x, 0.5x, 1x, 2x |
| Effectiveness 2 (Eff2) | Damage multiplier from AMT vs. DPT2. | x (multiplier) | 0x, 0.5x, 1x, 2x |
| Total Multiplier (TM) | The final combined damage multiplier. | x (multiplier) | 0x, 0.25x, 0.5x, 1x, 2x, 4x |
Practical Examples (Real-World Use Cases)
Let’s look at how the Pokémon Type Calculator helps in common battle scenarios.
Example 1: Single-Type Defender
Imagine your opponent sends out a pure Grass-type Pokémon like Venusaur.
- Attacking Move Type: Fire
- Defending Pokémon Type 1: Grass
- Defending Pokémon Type 2: None
Calculation:
- Fire vs. Grass = 2x (Super Effective)
- Fire vs. None = 1x (Neutral)
- Total Multiplier = 2x * 1x = 2x Super Effective!
Interpretation: A Fire-type move will deal double damage to Venusaur. This is a strong offensive choice.
Example 2: Dual-Type Defender with Mixed Effectiveness
Your opponent has a Dragon/Flying-type Pokémon like Dragonite.
- Attacking Move Type: Ice
- Defending Pokémon Type 1: Dragon
- Defending Pokémon Type 2: Flying
Calculation:
- Ice vs. Dragon = 2x (Super Effective)
- Ice vs. Flying = 2x (Super Effective)
- Total Multiplier = 2x * 2x = 4x Super Effective!
Interpretation: An Ice-type move will deal quadruple damage to Dragonite, making it an incredibly potent attack. This highlights a critical double weakness.
Example 3: Dual-Type Defender with Resistance and Weakness
Consider attacking a Grass/Poison-type Pokémon like Roserade.
- Attacking Move Type: Fighting
- Defending Pokémon Type 1: Grass
- Defending Pokémon Type 2: Poison
Calculation:
- Fighting vs. Grass = 1x (Neutral)
- Fighting vs. Poison = 0.5x (Not Very Effective)
- Total Multiplier = 1x * 0.5x = 0.5x Not Very Effective!
Interpretation: Despite Fighting being neutral against Grass, its weakness against Poison makes the overall attack “Not Very Effective.” This shows how dual types can mitigate damage.
How to Use This Pokémon Type Calculator
Our Pokémon Type Calculator is designed for ease of use, providing quick and accurate type effectiveness results. Follow these simple steps to get the most out of it:
Step-by-Step Instructions:
- Select Attacking Move Type: In the “Attacking Move Type” dropdown, choose the elemental type of the move you are considering using. For example, if you’re planning to use a “Flamethrower” move, select “Fire.”
- Select Defending Pokémon Type 1: In the “Defending Pokémon Type 1” dropdown, choose the primary type of the Pokémon you are attacking. Every Pokémon has at least one type.
- Select Defending Pokémon Type 2 (Optional): If the defending Pokémon has a secondary type (e.g., Charizard is Fire/Flying), select it from the “Defending Pokémon Type 2” dropdown. If the Pokémon is a single type, leave this as “None.”
- View Results: The calculator will automatically update the results in real-time as you make your selections. There’s no need to click a separate “Calculate” button unless you want to manually trigger it after changing multiple inputs quickly.
- Reset: If you want to clear all selections and start over, click the “Reset” button.

How to Read Results:
- Primary Highlighted Result: This large, colored text shows the final damage multiplier (e.g., “2x Super Effective!”, “0.5x Not Very Effective!”, “0x Immune!”). The color changes to indicate the severity of the effectiveness.
- Intermediate Results: Below the primary result, you’ll see a breakdown:
- Move Type: Confirms your selected attacking move type.
- Defender Type 1: Shows the primary defending type and its individual effectiveness against the move.
- Defender Type 2: Shows the secondary defending type (if applicable) and its individual effectiveness.
- Total Multiplier: The final combined multiplier, which is the product of the individual effectiveness values.
Decision-Making Guidance:
Use the results from the Pokémon Type Calculator to make strategic decisions:
- Super Effective (2x, 4x): Prioritize these moves for maximum damage. A 4x weakness is often a one-hit knockout opportunity.
- Neutral (1x): These moves are reliable but won’t provide a damage bonus. Consider using them if you lack super-effective options or if the move has high base power.
- Not Very Effective (0.5x, 0.25x): Avoid these moves if possible, as they will deal significantly reduced damage. Switch Pokémon or use a different move.
- Immune (0x): Never use a move against a Pokémon that is immune to its type. It will deal no damage and waste a turn.
Key Factors That Affect Pokémon Type Calculator Results
While the Pokémon Type Calculator focuses on the fundamental type interactions, several other factors influence the actual damage dealt in a Pokémon battle. Understanding these can further refine your strategy.
- Move Type vs. Defender Types: This is the core interaction calculated by the Pokémon Type Calculator. The elemental properties of the attacking move and the defending Pokémon’s type(s) determine the base damage multiplier.
- Dual-Type Interactions: Pokémon with two types have unique strengths and weaknesses. A move might be super effective against one type but resisted by the other, leading to a neutral (1x) overall effect. Conversely, a move could be super effective against both, resulting in a devastating 4x weakness.
- STAB (Same Type Attack Bonus): If a Pokémon uses a move that matches one of its own types, that move receives a 1.5x damage bonus. This is applied *after* type effectiveness. For example, a Fire-type Pokémon using a Fire-type move against a Grass-type Pokémon would deal 2x (type effectiveness) * 1.5x (STAB) = 3x damage.
- Pokémon Abilities: Many Pokémon have special abilities that can alter type effectiveness. For instance, Levitate makes a Pokémon immune to Ground-type moves, regardless of its actual typing. Dry Skin makes a Pokémon weak to Fire but immune to Water. Always check a Pokémon’s ability!
- Held Items: Certain items can influence damage. Expert Belt boosts super-effective moves by 20%, while type-specific resistance berries (e.g., Occa Berry for Fire) reduce super-effective damage by 50%.
- Weather Conditions: Weather effects can boost or reduce damage for specific types. For example, Sunny Day boosts Fire-type moves by 50% and reduces Water-type moves by 50%. Rain Dance does the opposite.
- Critical Hits: A critical hit ignores defensive stat boosts and deals 1.5x damage (in most recent generations). This is a random factor but can turn the tide of battle.
- Stat Differences: The attacking Pokémon’s Attack/Special Attack stats and the defending Pokémon’s Defense/Special Defense stats are crucial. A super-effective move from a weak attacker might do less damage than a neutral move from a strong attacker.
Frequently Asked Questions (FAQ) about Pokémon Type Effectiveness
A: “Super Effective” means the attacking move’s type is particularly strong against the defending Pokémon’s type(s), resulting in increased damage (typically 2x or 4x).
A: “Not Very Effective” means the attacking move’s type is weak against the defending Pokémon’s type(s), resulting in reduced damage (typically 0.5x or 0.25x).
A: “Immune” means the attacking move’s type has no effect on the defending Pokémon’s type(s), resulting in 0x damage. The attack will completely fail to deal damage.
A: For dual-type Pokémon, the effectiveness of the attacking move is calculated against *both* of its types, and these two multipliers are then multiplied together. For example, an Ice move against a Dragon/Flying Pokémon would be 2x (vs. Dragon) * 2x (vs. Flying) = 4x total.
A: No, the Pokémon Type Calculator focuses purely on type effectiveness multipliers. STAB is a separate 1.5x damage bonus applied if a Pokémon uses a move that matches one of its own types. You would multiply the calculator’s result by 1.5 if STAB applies.
A: Yes, certain Pokémon abilities (e.g., Levitate, Wonder Guard) or held items can alter type effectiveness, making a Pokémon immune to types it normally wouldn’t be, or changing resistances/weaknesses. The calculator shows base type interactions.
A: It’s the cornerstone of strategy! Knowing type effectiveness allows you to choose moves that deal maximum damage, switch into Pokémon that resist incoming attacks, and exploit opponent weaknesses, significantly increasing your chances of winning.
A: The type chart used in this Pokémon Type Calculator is based on the most recent main series Pokémon games (Generation 6 onwards, which introduced the Fairy type). While older games had slightly different charts (e.g., no Fairy type), this calculator provides the most current and widely applicable information.
