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.
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.
Major credit to u/__isitin__ for digging up the data.
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, a new “Refine” button will appear. 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. 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 fo 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.
