Type Chart Calculator

When it comes to competitive Pokémon battles or in-game planning, type matchups can make or break your success. One of the key elements in Pokémon is understanding how different types interact. That’s where our Pokémon Type Effectiveness Calculator comes in — a simple, powerful tool designed to help you determine how effective an attacking move will be against one or two defending types.

Whether you’re preparing for a gym battle, building your perfect team, or simply brushing up on your knowledge, this tool will help you make smarter decisions instantly.

🛠 What is the Type Effectiveness Calculator?

The Type Effectiveness Calculator is an interactive tool that allows users to select an attacking Pokémon type and one or two defending types to determine how much damage an attack will do.

The calculator uses the official Pokémon type matchup chart to calculate:

  • Damage multiplier (e.g., 2×, 0.5×, 0×)
  • Effectiveness outcome (e.g., Super Effective, Not Very Effective, No Effect)

This is especially helpful when facing dual-type Pokémon, as the combination of resistances and weaknesses can be confusing.

✅ How to Use the Tool (Step-by-Step)

Using the calculator is simple and takes just a few seconds. Here’s how to do it:

Step 1: Choose the Attacking Type

  • Use the dropdown labeled “Attacking Type” to select the type of the move your Pokémon will use (e.g., Fire, Water, Electric).

Step 2: Select Defending Type 1

  • This is the primary type of the opponent’s Pokémon. Select it from the “Defending Type 1” dropdown.

Step 3: (Optional) Choose Defending Type 2

  • If the opponent’s Pokémon is a dual-type, select the secondary type from the “Defending Type 2” dropdown. If not, leave this blank.

Step 4: Click “Calculate”

  • Hit the “Calculate” button, and your result will appear below, including:
    • A textual result (e.g., Super Effective)
    • A numeric damage multiplier (e.g., 2×)
    • A helpful explanation sentence

Step 5: Reset if Needed

  • Want to try a new combo? Hit the “Reset” button to clear all selections and start again.

🔍 Example Use Case: Know Before You Battle

Let’s walk through a real-world example:

Scenario: You’re planning to use a Water-type move against a Rock/Ground-type Pokémon like Golem.

Step-by-Step:

  1. Set Attacking Type to Water.
  2. Set Defending Type 1 to Rock.
  3. Set Defending Type 2 to Ground.
  4. Click “Calculate”.

Result:

  • Damage Multiplier: 4×
  • Effectiveness: Super Effective
  • Explanation: A Water-type attack against a Rock/Ground-type Pokémon will be super effective.

This lets you know that using a Water-type move is not just good — it’s twice as good due to both defending types being weak to it.

❓ FAQs: Pokémon Type Effectiveness Calculator

1. What is a damage multiplier?

A number that tells how effective a move is. For example, 2× means double damage, 0.5× means half damage.

2. Can a move do zero damage?

Yes, some types are completely immune to others (e.g., Normal moves don’t affect Ghost-types).

3. How is the result calculated?

The tool multiplies effectiveness against both defending types using an internal type chart.

4. Is this based on the official Pokémon games?

Yes, it uses the official type matchup data from the mainline Pokémon series.

5. Why does some type matchups result in 4× or 0.25×?

These extreme values happen when both types share the same weakness or resistance.

6. Can this tool help in competitive Pokémon?

Absolutely. Strategic knowledge of type effectiveness is vital in competitive formats.

7. Does this consider move categories like Physical or Special?

No, this tool is purely for type matchups, not move mechanics.

8. Can I use this for Pokémon GO battles?

Yes! Type effectiveness functions similarly in Pokémon GO, making this tool quite useful.

9. Why is Ground immune to Electric?

This is a core rule in Pokémon: Electric moves do nothing to Ground-types.

10. How do dual-types affect damage calculation?

Each type has its multiplier; both are combined (multiplied together) to find the final value.

11. Why is Fighting ineffective against Ghost?

Fighting moves literally can’t hit Ghost Pokémon — it’s a unique immunity.

12. Is the calculator mobile-friendly?

Yes, the tool is designed to be responsive and usable on mobile devices.

13. Can I embed this on my own website?

This depends on licensing and ownership. Reach out to the site owner for permission.

14. What if I don’t choose a second defending type?

The calculator assumes the defending Pokémon is single-type and uses just one multiplier.

15. Do STAB (Same Type Attack Bonus) effects apply?

Not in this tool — it only shows type matchup effectiveness, not bonuses.

16. What is a ‘Super Effective’ result?

It means the attack will do more than normal damage (usually 2× or more).

17. Is Fairy weak to Steel?

Yes, Steel is super effective against Fairy, making it a good counter.

18. What does “Not Very Effective” mean?

It indicates resistance — your attack will do less damage (0.5× or lower).

19. What happens with dual-type resistances?

The two resistances multiply. For example, 0.5 × 0.5 = 0.25× total damage.

20. Do legendary Pokémon follow the same rules?

Yes, regardless of status or stats, type interactions are consistent.
