This Tool

This tool calculates your Pokemon's hidden Individual Values (IVs). It uses following information:

You can check multiple boxes if your team leader says more than one stat is its best.

Note, we're calling the stat "HP" because that's what Niantic chose to use in the leader text. Really, the IV is "Stamina" and this IV drives the "HP" and CP of the Pokemon, see formulas below. HP and Stamina are two different numbers, Niantic has chosen to confuse them. The leaders should be saying the best stat is "Stamina". We're not bitter at all.

If you've scored a 90%+ Pokemon, have a look at Trainer Gear to make sure your personal equipment set is as complete as your Pokemon's IVs.

IV's Explained

Each type of Pokemon has a base set of attributes for Stamina, Attack and Defence. Each specific Pokemon is "born" with it's own IV (individual values), that further increase these stats by 0-15 extra points. You can not change the IV's, not all Pokemon are born equal.

These IV's make small differences in the final power of a Pokemon. For example, the base attributes of a Charizard are 212, 182, 156. This would be the "worst" charizard available where all IV's are zero. With max IV's, a Charizard would have 227, 197, 171. Each of these Atk, Def and Stam values for Charizard are only 7-10% better.

Nonetheless, if having the absolute best Pokemon is critical to you, this tool wll help you find the hidden IV values that your Pokemon has so you can decide to keep it or try for something better. Absolute perfection isn't just having the best IV's, the "perfect" Pokemon would have both maximum IVs AND the best Moveset possible. Note that your Pokemon's maximum level is governed by your trainer level. To level yourself up faster, and therefore gain access to leveling up your Pokemon further, check out XP Batching.

This tool uses the two following formulas and the inputs you provide about your Pokemon to attempt to identify its IVs:

HP = (Base Stam + Stam IV) * Lvl(CPScalar)

CP = (Base Atk + Atk IV) * (Base Def + Def IV)^0.5 * (Base Stam + Stam IV)^0.5 * Lvl(CPScalar)^2 / 10

Note that Pokemon have hidden levels and each level requires two "Power-Ups", this tool will display Level 4.5 if your Pokemon has had one Power-Up after level 4.

Too see how these stats can be used to your advantage in battle, check out the Best Attacker and Best Defender tools.

Refining Results

There can be many possible IV's that would produce the Pokemon you have. You are able to narrow down the Pokemon by leveling it up OR evolving it, and submitting the new details to this tool

After your first search, use the "Refine" button instead of "Calculate". Power-up the Pokemon once OR evolve it, observe its new CP HP and Dust Prices, enter the new details, then click "Refine".

The "Refine" process will automatically identify if you evolved the mon (species changed) or if you powered it up and the powered up field is now set to "Yes". But only one at a time. Don't attempt to evolve and powerup between submissions, or powerup multiple times between submissions. The tool assumes you're taking it one step at a time.

Some Pokemon can have their IV's identified immediately, other will require up to 5 Power-Ups to know exactly which IV set it has. Regardless, you should know within 0-1 powerups if it's "close to perfect".

Pokemon with 10CP or 10HP

So these are a bit of a pain. Niantic rounds up those formulas above to 10 if they ever score below. So if you put in a Rattata you just caught, with 10CP and 10HP, you'll find that it can have 4096 possible IV combinations and be anywhere from 0-93% perfect.

Unfortunately, for some Pokemon, that's just the way it is, you can not know if it's good a good set of IV's or a poor set until you Power it up a couple times.
