Pokemon Type Weakness Calculator
If you’re a competitive Pokémon trainer or just someone who wants to build better battle strategies, understanding type matchups is essential. Our Pokémon Type Calculator is an intuitive, easy-to-use tool that helps you quickly determine a Pokémon’s weaknesses, resistances, and immunities based on its primary and secondary types.
Whether you’re training your starter, battling in online PvP matches, or building a well-balanced team for Elite Four challenges, this tool gives you the strategic insight you need in seconds.
🔍 What Is the Pokémon Type Calculator?
The Pokémon Type Calculator is a free web-based tool designed to help trainers analyze how different Pokémon types interact with each other. Simply select a primary type (required) and an optional secondary type, and the calculator will display:
- Types that deal double (2×) or quadruple (4×) damage (weaknesses)
- Types that deal half (0.5×) or quarter (0.25×) damage (resistances)
- Types that deal no damage (0×) (immunities)
- Types that deal normal (1×) damage
This tool is based on the official Pokémon type effectiveness chart, which determines how effective moves are based on the attacking and defending types.
🛠️ How to Use the Pokémon Type Calculator
Using the calculator is incredibly simple and takes only a few seconds:
- Select the Primary Type
Choose your Pokémon’s main type from the dropdown menu (e.g., Fire, Water, Ghost). - (Optional) Select the Secondary Type
If your Pokémon is dual-type, select the second type (e.g., Flying, Dragon). If it’s a single-type Pokémon, leave this blank. - Click “Calculate”
Instantly see your Pokémon’s type matchups displayed under four categories: Weak To, Resistant To, Immune To, and Normal Damage From. - Review and Apply
Use the information to decide the best moves, switch-ins, and battle strategies for your Pokémon. - Click “Reset” if you want to start over with a different Pokémon.
🧪 Practical Example
Let’s say you have a Garchomp, which is a Dragon/Ground type Pokémon.
- Primary Type: Dragon
- Secondary Type: Ground
After clicking “Calculate”, the tool will show:
- Super weak to (4×): Ice
- Weak to (2×): Dragon, Fairy
- Resistant to (0.5×): Fire, Poison, Rock
- Immune to (0×): Electric
- Normal damage from: Everything else not listed
This means Garchomp must avoid Ice-type moves at all costs (since it takes 4× damage!) but is a great pick against Electric-types thanks to its immunity.
💡 Why Type Matchups Matter
In the world of Pokémon, every move and every matchup counts. Here’s why you should use this tool:
- Avoid Fatal Matchups: Knowing type weaknesses can prevent you from losing a battle in one hit.
- Plan Switch-Ins: When you know your opponent’s likely move, you can switch to a Pokémon that resists or is immune to it.
- Choose the Right Moves: Selecting the right attacking move type based on your opponent’s typing gives you the upper hand.
- Build Better Teams: Balance your team by covering different types and minimizing shared weaknesses.
🤔 Frequently Asked Questions (FAQs)
1. What does 4× weakness mean?
It means the Pokémon takes four times normal damage from a specific type due to both its types being weak to it.
2. Can a Pokémon have no weaknesses?
Yes, a few Pokémon (like Eelektross with Levitate) can have no weaknesses due to immunity or resistances.
3. Why can’t I select the same type for both primary and secondary?
That would duplicate the type, which doesn’t happen in actual Pokémon games. Our tool prevents this for accuracy.
4. Is this tool updated for all current Pokémon games?
Yes, this calculator uses the modern type effectiveness chart, including Fairy and Steel types.
5. Do abilities affect the results?
No. This tool calculates based only on types, not abilities like Levitate or Flash Fire.
6. Is this calculator useful for PvP battles?
Absolutely! It’s perfect for planning team counters and predicting your opponent’s strategy.
7. Can I use this to check offensive effectiveness?
No, this tool focuses on defensive typing—how much damage the Pokémon takes, not deals.
8. What is immunity?
A type that deals 0× damage to your Pokémon. For example, Ghost-types are immune to Normal and Fighting.
9. How are dual-type calculations made?
We multiply effectiveness values. For example, if one type is weak to Fire (2×) and the other resists it (0.5×), net effect = 1× (normal damage).
10. What does “normal damage” mean?
It means the Pokémon takes standard (1×) damage—no resistance, weakness, or immunity.
11. What are “super resistances”?
When two types both resist the same type, it becomes 0.25× damage (e.g., Steel/Bug vs. Grass).
12. Does this tool work on mobile?
Yes, it’s fully responsive and works on all modern smartphones and tablets.
13. How many Pokémon are dual-type?
Over half of all Pokémon are dual-type, making this calculator especially useful.
14. Can I use this for older generations?
While it aligns best with current gen mechanics, it’s mostly compatible with Gen 6 onward.
15. Is Steel still weak to Dark or Ghost?
No, that was true before Gen 6. The tool reflects current typing where Steel is no longer resistant to Dark or Ghost.
16. Why is my Flying-type Pokémon immune to Ground?
Flying Pokémon naturally avoid Ground attacks unless grounded (e.g., by Gravity or Smack Down).
17. Do mega evolutions affect type?
Yes, but this tool only calculates types you manually select. Input the mega-evolved type to get accurate results.
18. What’s the best way to use this tool during battle?
Keep it open in a browser tab or use it during team-building to anticipate threats.
19. Is Fairy-type weak to anything?
Yes, Fairy is weak to Steel and Poison, so plan accordingly.
20. Can I suggest improvements for this tool?
Absolutely! Reach out via the site’s contact page with suggestions or new features you’d like to see.
