What This Pokémon Type Calculator Does
This tool helps you answer one of the most common questions in Pokémon battles: How much damage will this type do? Instead of memorizing every interaction in the type chart, you can pick an attacking type, choose your opponent’s typing, and instantly see the exact effectiveness multiplier.
It supports both single-type and dual-type defenders. That means if you are trying to evaluate a matchup like Electric versus Water/Flying, or Fire versus Steel/Grass, you can check it in seconds and plan your move with confidence.
How to Use the Calculator
1) Select the move’s attacking type
This is the type of the move you want to use (for example: Ground, Fairy, or Ghost).
2) Select the target’s typing
Choose the primary defending type, then add a second type if the target is dual-typed. If it has only one type, keep the second type set to None.
3) Click Calculate Matchup
You’ll get the exact multiplier (0×, 0.5×, 1×, 2×, 4×, etc.) and a quick interpretation of whether the move is strong, neutral, weak, or completely ineffective.
Understanding the Multipliers
- 0× — No effect (immunity)
- 0.25× — Double resistance (very poor damage)
- 0.5× — Not very effective
- 1× — Neutral damage
- 2× — Super effective
- 4× — Double weakness (massive damage)
Dual types multiply together. For example, if one type resists and the other is weak to the same move, the result can become neutral.
Why Dual Typing Changes Everything
Resistances can stack
When both defending types resist the same attacking type, the result drops to 0.25×. That can turn a normally dangerous move into chip damage.
Weaknesses can stack
If both defending types are weak to an attacking type, you get a 4× weakness. These are high-priority targets for offensive pressure.
Immunities override normal matchups
Any immunity in a type pairing makes the final multiplier 0× for that attack type, no matter what the other type says. This is crucial for safe switch-ins and prediction.
Practical Team-Building Tips
Build offensive coverage
Use this calculator to test common combinations and make sure your moveset can hit most opponents for at least neutral damage.
Patch defensive holes
Check the weakness profile of your key Pokémon and add teammates that resist those attack types. Balanced cores reduce the chance of getting swept by one threat.
Plan around immunities
Knowing when your move does 0× is just as important as knowing when it does 2×. Smart players avoid wasting turns into immunity walls.
Common Questions
Does this include abilities, items, weather, or terrain?
No. This calculator focuses on core type-chart interactions only. Battle mechanics like abilities (for example, Levitate), held items, or weather are not included.
Does this include STAB?
No. Same-Type Attack Bonus is separate from type effectiveness. This tool shows the matchup multiplier only.
Which generation chart is used?
The calculator uses the modern 18-type chart used in current mainline games (including Fairy type interactions).
Final Takeaway
If you want faster battle decisions, better coverage, and cleaner team construction, a reliable Pokémon type calculator is one of the best tools you can use. Bookmark this page, test your matchups, and turn type knowledge into more consistent wins.
