Instantly determine the defensive weaknesses, resistances, and immunities of any single or dual-type Pokémon. Whether you are planning a competitive team or preparing for a tough Gym Battle, this calculator provides the exact damage multipliers you need.

Pokémon Weakness Calculation Formula
The calculation of type effectiveness is based on a multiplier system. When a Pokémon has only one type, the effectiveness is determined by the standard Type Matchup Chart.
Dual-Type Effectiveness
For a Pokémon with two types (Dual-Type), the final damage multiplier is the product of the two individual type multipliers:
This results in four possible key categories for defensive weakness:
- 4x Weakness (Double Weakness): If both types are weak (2x) to the attacking type (e.g., Grass/Flying vs Ice).
- 0.25x Resistance (Quad Resistance): If both types resist (0.5x) the attacking type (e.g., Ground/Rock vs Fire).
Variables for the Weakness Calculator
This calculator requires up to two variables to perform the analysis:
- Primary Pokémon Type: The first type of the Pokémon, selected from the list of 18 types. This input is mandatory.
- Secondary Pokémon Type (Optional): The second type of the Pokémon. If this is left blank, the calculation is performed as a single-type Pokémon.

What is the Pokémon Weakness Calculator?
The Pokémon Weakness Calculator is a crucial tool for competitive and casual play that quickly identifies a Pokémon’s defensive profile against all 18 types. Defensive typing is the most important factor in determining survivability in battle. By knowing your weaknesses, you can effectively plan your switch-ins and choose allies that cover your vulnerabilities.
The interaction between types can be complex, especially with dual-type Pokémon. This tool automates the multiplication of individual type resistances and weaknesses, eliminating the need for manual chart lookup and potential mathematical errors. It quickly groups the results into categories like Weaknesses (2x, 4x), Neutral (1x), Resistances (0.5x, 0.25x), and Immunities (0x).
How to Calculate Pokémon Weakness (Example: Grass/Flying Type)
Let’s use a dual-type Pokémon like Tropius (Grass/Flying) to demonstrate the calculation steps:
- Select Types: Select ‘Grass’ as the Primary Type and ‘Flying’ as the Secondary Type in the calculator inputs.
- Analyze Attack Type (e.g., Ice): We check how the Ice type interacts with both Grass and Flying:
- Ice attacks vs. Grass type: 2x (Super Effective)
- Ice attacks vs. Flying type: 2x (Super Effective)
- Determine Total Multiplier: Multiply the individual multipliers: $2 \times 2 = 4$.
- Final Result: Tropius has a 4x weakness (Double Weakness) to Ice-type attacks.
- Analyze Attack Type (e.g., Ground):
- Ground attacks vs. Grass type: 0.5x (Not Very Effective)
- Ground attacks vs. Flying type: 0x (Immunity)
- Determine Total Multiplier: Multiply the individual multipliers: $0.5 \times 0 = 0$.
- Final Result: Tropius is immune (0x) to Ground-type attacks.
Frequently Asked Questions (FAQ)
- What is a 4x weakness? A 4x weakness, or double weakness, occurs when an attacking type is Super Effective (2x multiplier) against both of a Pokémon’s types. The damage dealt will be four times the normal base damage.
- Are there any types with no weaknesses? No type combination is completely immune to weaknesses. However, pure Normal-type and pure Ghost-type Pokémon only have one weakness each (Fighting and Ghost/Dark, respectively), offering strong defensive profiles.
- Does the order of Primary or Secondary Type matter? No, in terms of defensive effectiveness, the order of the types does not matter. The final damage multiplier is always the product of the two individual multipliers.
- Why are Fairy-type weaknesses often overlooked? Fairy-type has only two weaknesses (Poison and Steel) and is often paired with other types (like Psychic/Fairy) to minimize vulnerabilities, making it one of the strongest defensive types introduced in later generations.
