Pokemon GO IV Calculator
Enter your Pokémon's CP and HP and pick the species — the calculator finds every Attack/Defense/Stamina IV combination that matches, with the IV percentage. Add the level (from the power-up arc or appraisal) to narrow it to one answer.
Find your Pokémon's hidden IVs
The Pokémon GO IV calculator works out every Attack, Defense and Stamina IV combination that matches your Pokémon's CP and HP. Pick the species, enter CP and HP, and the Pokémon GO IV calculator lists each possible IV spread with its percentage.
How it works
A Pokémon's CP and HP come from its species base stats, its level (the CPM value) and its three hidden IVs. The Pokémon GO IV calculator tries every IV combo (0–15 each) and keeps the ones that reproduce your exact CP and HP.
Narrowing it down
Several IV spreads can give the same CP and HP at different levels, so add the level (from the power-up arc) or use the in-game appraisal to get a single answer. The CPM table is the standard extracted values, so results match the game exactly — verified against a perfect Mewtwo (CP 4178, HP 180 at level 40).
