What this Pokémon XY IV calculator does

In Pokémon X and Y, Individual Values (IVs) determine how strong a Pokémon can become in each stat: HP, Attack, Defense, Special Attack, Special Defense, and Speed. Each IV ranges from 0 to 31, where 31 is perfect. This calculator reverse-engineers the Gen VI stat formula to find all IV values that match your observed stat at a given level.

Because in-game stats are rounded down at specific steps, one observed stat can sometimes match several IVs, especially at lower levels. That is normal. As your Pokémon levels up, the range usually narrows.

How to use the calculator correctly

1) Collect accurate inputs

• Level: Use the exact current level shown in game.
• Base Stat: Use the species base stat for the stat being tested.
• Observed Stat: Enter the exact value from your summary screen.
• EVs: Use known EV investment if you trained the Pokémon yourself.
• Nature: Choose boosting, neutral, or hindering for that specific stat.

2) Mark HP when needed

HP uses a different formula and does not apply nature multipliers. Tick This is HP when calculating HP IVs; the calculator automatically ignores nature in that case.

3) Interpret the output

The tool reports all matching IV values plus a min-max range. If you get a wide range, test again at a higher level or with cleaner EV data.

Gen VI formulas used (X/Y compatible)

Non-HP stats (Atk/Def/SpA/SpD/Spe)

Stat = floor((floor(((2 × Base + IV + floor(EV / 4)) × Level) / 100) + 5) × Nature)

HP stat

HP = floor(((2 × Base + IV + floor(EV / 4)) × Level) / 100) + Level + 10

Tips for better IV accuracy in Pokémon X/Y

• Check Pokémon at level 50+ whenever possible for tighter IV results.
• Use freshly hatched Pokémon with known EVs (usually 0) for easiest calculations.
• Remember that vitamins, Super Training, and Horde training affect EV totals.
• If you are breeding, combine this with Destiny Knot and Everstone for consistent results.

Frequently asked questions

Does this also work for Omega Ruby/Alpha Sapphire?

Yes. ORAS uses the same Gen VI stat framework, so this approach is valid there too.

Why can't I always get one exact IV value?

Rounding and level scaling can make multiple IV values produce the same final stat. This is most common at low levels.

Can this calculate Hidden Power type?

Not directly. Hidden Power requires parity patterns across all six IVs. Use this tool per stat first, then combine results with a dedicated Hidden Power checker.

Final note

A Pokémon XY IV calculator is most powerful when paired with disciplined record-keeping: known parent IVs, controlled EVs, and level checkpoints. Use this page as a fast stat-to-IV reverse check while breeding, team building, or validating catches in Friend Safari.
