Pokémon X/Y IV Calculator (Single Stat)
Use this tool to estimate IVs for one stat in Pokémon X and Pokémon Y. Enter your Pokémon's base stat, observed stat, level, EVs, and nature effect to get possible IV values from 0 to 31.
How this Pokémon IV calculator for XY works
In Pokémon X/Y, each stat is built from four core values: base stat, level, EVs, and IVs. Since IVs are hidden, players reverse-calculate them from the stat shown in-game. This calculator does exactly that by checking every IV value from 0 to 31 and returning every one that matches your inputs.
If only one IV matches, your IV is exact. If several match, you get a range. This is common at lower levels where rounding causes overlap between neighboring IV values.
Stat formulas used in Generation 6
HP Formula
HP = floor(((2 × Base + IV + floor(EV/4)) × Level) / 100) + Level + 10
Other stats Formula
Stat = floor((floor(((2 × Base + IV + floor(EV/4)) × Level) / 100) + 5) × Nature)
- Nature = 1.1 for boosted stats
- Nature = 1.0 for neutral stats
- Nature = 0.9 for lowered stats
Input guide for accurate results
1) Base stat
Use the exact base stat for the species and form you are checking. Mega Evolutions have different base stats than their normal forms, so confirm the right one.
2) Observed stat
Enter the stat shown on the summary screen at the current level. Make sure no temporary battle effects are involved; this tool is for permanent stat values only.
3) EVs
Known EVs produce better precision. If your EVs are uncertain, results may show a wider IV range. In XY, super training and horde training are common ways to track EV investment.
4) Nature effect
Natures affect non-HP stats only. For HP, nature is ignored by the formula. If you pick the wrong nature effect, the calculator may return no valid IVs.
Why you might get multiple possible IVs
At low levels, rounding makes several IV values produce the same visible stat. To narrow the range:
- Level up and recalculate
- Use rare candies temporarily for cleaner checkpoints
- Check at level 50 or 100 for sharper separation
- Verify EV count and nature selection
Breeding and training tips for Pokémon XY
- Destiny Knot: Passes 5 combined IVs from parents, key for competitive breeding.
- Everstone: Locks nature inheritance from the holding parent.
- Friend Safari: Great source of Pokémon with solid IV potential.
- Judge NPC (Kiloude City): Helpful qualitative IV feedback for quick filtering.
Example quick check
Suppose you're checking Speed on a level 50 Pokémon with base Speed 110, observed Speed 167, 0 EVs, and a beneficial nature. Enter those values, then calculate. If the result includes only 31, you have perfect Speed IV. If it shows multiple values, level it up and test again.
Frequently asked questions
Does this calculator work for ORAS too?
Yes. ORAS uses the same Gen 6 stat formulas, so this method is valid there as well.
Can this include Hyper Training?
No. Hyper Training is a later-generation mechanic and does not exist in Pokémon XY.
Why does it say no valid IV found?
Usually one input is off: wrong base stat, wrong nature effect, unknown EVs, or incorrect observed stat.
