Here’s Everything You Need To Know About How IVs Work In Pokémon GO

Pokémon GO how ivs work

IV stands for ‘Individual Value’, and it’s a hidden stat that all Pokémon have. In Pokémon GO, the IV value will range from 0-15 for every stat (attack, defense, and stamina). A Pokémon is randomly assigned an IV between 0-15 for each stat when it is caught/hatched from an egg, and it won’t ever change.

To better explain how IVs work, let’s use an example. Snorlax has base stats of 320 STA, 180 ATK, and 180 DEF. These base stats will be the same for every single Snorlax in the game, with no exceptions.

However, let’s say one Snorlax has a perfect IV split (15 for each stat), and another Snorlax has a not-so-perfect IV split of only 10 for each stat. The first Snorlax would now have 335 STA, 195 ATK, and 195 DEF, while the second Snorlax has 330 STA, 190 ATK, and 190 DEF.

Remember, it’s these stats (STA, ATK, and DEF) that contribute to a Pokémon’s CP (combat points), which means if all other things are equal, a Pokémon with higher IVs will be stronger than a Pokémon of the same species with lower IVs, which is why it is important that you pay attention to your Pokémon’s IV split.

But if IVs are a hidden stat, how do we determine if our Pokémon are strong or weak? Well, some clever folks have figured out a way to use mathematics and the stats we are given about our Pokémon in-game to calculate IVs, and because they’re so nice, they even made a calculator for us to use.


Thanks to TheSilphRoad over on Reddit, we now have this handy dandy calculator that we can use to work out what IVs our Pokémon possess. You can check it out by clicking here.

Simply type in the name of the Pokémon you want to analyze, enter its current CP, HP, the candy required to power it up, and whether or not you’ve powered it up before, and the calculator will tell you two things:

  1. The calculator will tell you the IV split of your Pokémon.
  2. The calculator will tell you what % perfect your Pokémon is. 100% means you have a 15/15/15 split, which is perfect, it’s the highest you can get. Conversely, a 0% means you have a 0/0/0 split, which is the worst you can get (I’m not sure if you can even get an IV split that low, so don’t quote me on it.)

The calculator is very easy to use, and as far as playing around with numbers go, it’s actually quite fun. I’ve seriously spent hours putting in the values for all of my Pokémon just to see how good their IVs were (and, for the record, my best was a 97% Magikarp (15/14/15) that I’m hoping will get a good move-set when he evolves).


One final thing about IVs before we wrap this all up is how hatched Pokémon differ from caught Pokémon. What I’ve found from personal experience, and what other users have noticed as well, is that hatched eggs tend to have better IVs than caught Pokemon. This is important.

Reddit user Shaeress has found that, on average, a hatched Pokémon will have an extra 9 IVs (spread over 3 stats, so an average of +3 to each stat) when compared to a Pokémon that was caught in the wild. This means that if you’re after a perfect 15 split, you’re better off hatching Pokémon rather than catching them.

But hey, before you go running off trying to find the perfect Pokémon with a 15/15/15 split, IVs aren’t the be all and end all when it comes to how strong your Pokémon is. For example, the move-set that your Pokémon possesses has a bigger impact on your success in battle than IVs do at this current point in time.

So what are you waiting for? Get out there and start hunting for the perfect Pokémon; one with both a superb move-set and a great IV split. When you’ve got a Pokémon that fulfills both of those criteria, that’s when you know you’ve got a winner on your hands.

Have you managed to get a perfect Pokémon yet? What’s the best IV split you’ve got? Let me know in the comments below!
