What is the Hidden Power Power Calculator?

The Hidden Power Power Calculator is a specialized tool designed for Pokémon trainers and competitive battlers playing Generations 2 through 5 (Gold/Silver through Black 2/White 2), and for checking types in later generations. Hidden Power is a unique move whose element (Type) and strength (Base Power) are determined entirely by the Pokémon’s Individual Values (IVs).

Unlike standard moves with fixed attributes, Hidden Power allows a Pokémon to use a move of a type it normally wouldn’t learn, providing crucial coverage against counter-strategies. While Generation 6 fixed the Base Power to 60, earlier games utilized a complex formula where power fluctuated between 30 and 70. This calculator solves that formula instantly.

Common misconceptions include thinking Hidden Power changes with EVs (Effort Values) or Level. It does not. It is intrinsically tied to the “genetics” (IVs) of the Pokémon, meaning it is set from the moment the Pokémon is generated or hatched.

Hidden Power Formula and Mathematical Explanation

The game calculates Hidden Power using binary representations of the Pokémon’s 6 stats: HP, Attack, Defense, Speed, Special Attack, and Special Defense.

Type Formula

The Type is determined by the “Least Significant Bit” (LSB) of each IV. Essentially, whether the IV is Odd (1) or Even (0).

Type Index = floor( (a + 2b + 4c + 8d + 16e + 32f) * 15 / 63 )

Where variables a through f represent the LSB of HP, Attack, Defense, Speed, Sp. Atk, and Sp. Def respectively.

Power Formula (Gen 2-5)

The Base Power is determined by the “Second Least Significant Bit”. This checks if the remainder of IV / 4 is 2 or 3.

Power = floor( (u + 2v + 4w + 8x + 16y + 32z) * 40 / 63 ) + 30

Variables used in the Hidden Power calculation logic.

Variable	Corresponds To	Bit Value Criteria	Multiplier (Type)
a / u	HP IV	LSB / 2nd LSB	1
b / v	Attack IV	LSB / 2nd LSB	2
c / w	Defense IV	LSB / 2nd LSB	4
d / x	Speed IV	LSB / 2nd LSB	8
e / y	Sp. Atk IV	LSB / 2nd LSB	16
f / z	Sp. Def IV	LSB / 2nd LSB	32

Practical Examples (Real-World Use Cases)

Example 1: Perfect IVs (All 31)

If a Pokémon has 31 in all stats (Odd numbers):

• Type Calculation: All bits are 1. Sum = 63. Formula: (63 * 15) / 63 = 15. Index 15 corresponds to Dark.
• Power Calculation: All 2nd bits are 1. Sum = 63. Formula: ((63 * 40) / 63) + 30 = 70.
• Result: Hidden Power Dark, Base Power 70. This is the standard for perfect Pokémon.

Example 2: Specific Engineering (BoltBeam Coverage)

An Electric type like Jolteon wants Hidden Power Ice or Grass to hit Ground types. For HP Ice with max power:

• Target IVs: 31 HP, 30 Atk, 30 Def, 31 Spe, 31 SpA, 31 SpD.
• Type Math: Atk and Def are Even (bit 0), others Odd (bit 1). Resulting Index corresponds to Ice.
• Power Math: 30 and 31 both have the 2nd bit set to 1. Thus, the power calculation sum remains 63, resulting in Base Power 70.
• Result: A competitive Jolteon capable of OHKOing a Garchomp.

How to Use This Hidden Power Power Calculator

1. Find your IVs: Use an IV checker in-game (usually an NPC in the Battle Tower/Subway/Maison) or an external IV calculator to determine your exact stats.
2. Enter Values: Input the 6 IV numbers (0-31) into the calculator fields above.
3. Analyze Type: The colored badge immediately shows the elemental type. Ensure this complements your Pokémon’s natural moveset.
4. Check Power: For Gen 2-5, aim for a power of 70. If the calculator shows a low number (e.g., 45), you may need to re-breed your Pokémon.
5. Copy Results: Use the “Copy Results” button to save the data to your clipboard for team building notes.

Key Factors That Affect Hidden Power Results

• Parity of IVs (Odd vs Even): This is the sole determinant of Type. Changing an IV from 31 (Odd) to 30 (Even) drastically shifts the type index.
• Magnitude of IVs (Bit 2): To achieve maximum power (70), your IVs generally need to be 30 or 31. Low IVs (like 0-3) often lack the “2nd bit,” reducing base power significantly.
• Speed IV Constraints: For Trick Room teams, you want 0 Speed IVs. This forces the Speed bit to 0, making certain Types (like Fire or Rock) harder to achieve with Max Power.
• Physical vs Special Split: Hidden Power is technically a Special move (Gen 4+), but its Type is calculated using Physical stats (Atk/Def) as well. You cannot ignore Attack IVs just because you are a Special Attacker if you want a specific Hidden Power.
• Generation Mechanics: In Gen 6 (X/Y) and later, Base Power is fixed at 60. This calculator’s Power result is strictly for legacy games (Gen 2-5).
• Fairy and Normal Types: Hidden Power cannot be Normal or Fairy type. The math simply does not output indices for these types.

Frequently Asked Questions (FAQ)

Can I get Hidden Power Fairy?

No. Hidden Power was introduced before the Fairy type existed, and the formula was never updated to include it. It also cannot be Normal type.

Why is my Base Power 60?

If you are playing Generation 6 (X/Y/ORAS) or Generation 7 (Sun/Moon), Hidden Power is fixed at 60 Base Power regardless of IVs. The IVs only determine the Type in these games.

Does Hyper Training affect Hidden Power?

No. Hyper Training affects stats virtually but does not change the underlying “true” IVs used for Hidden Power calculation. A Pokémon with poor natural IVs will retain its original Hidden Power type even after being Hyper Trained.

What is the best Hidden Power for Fire types?

Usually Hidden Power Grass or Ice, as these cover the Ground and Rock types that threaten Fire Pokémon.

Can I change my Hidden Power type?

Not directly. Since it is tied to IVs, you must breed a new Pokémon with different IVs to get a different Hidden Power.

Does Hidden Power get STAB?

Yes. If a Fire-type Pokémon uses Hidden Power Fire, it receives the Same Type Attack Bonus (1.5x damage).

How do I lower IVs for specific Hidden Powers?

In breeding, you can use “Power Items” to pass down specific IVs, or use RNG manipulation methods in older generations to ensure specific spreads like 31/30/30/31/31/31.

Is Hidden Power physical or special?

In Gen 2-3, it depended on the Type (Ghost was Physical, Psychic was Special). From Gen 4 onwards, Hidden Power is always a Special move.
