How the pokémon go iv calculator works
A Pokémon GO IV calculator tests the 4,096 possible Attack, Defense, and Stamina IV triples from 0 through 15. CP and HP compress those underlying values through floors, so several combinations can match the same display. Choose the correct species and power-up level, then enter CP and HP to filter the set.
The combat power multiplier, or CPM, represents level and runs in half-level steps. CP uses Attack linearly, Defense and Stamina through square roots, and CPM squared. The game floors the result and enforces a minimum of 10. HP separately floors Stamina plus its IV times CPM, also with a minimum of 10.
Stardust cost can help infer a level band but is not unique, and powered-up history matters. This implementation accepts an explicit level to avoid pretending dust alone identifies it. Best Buddy boosts and temporary forms should be handled with their active level and base stats. Species forms with different GO bases require the matching record.
Appraisal bars now reveal IV ranges directly in many cases. The search remains useful for cross-checking older screenshots, comparing candidate levels, or understanding why equal CP does not imply equal IV percentage. Attack weighs more strongly in CP than the other components, which is why lower-Attack spreads can be valuable under capped leagues.
Worked example
Using base values 118 Attack, 111 Defense, and 128 Stamina at level 40 (CPM 0.7903), a 15/15/15 individual has floor(133 × √126 × √143 × 0.7903² ÷ 10) = 1,115 CP and floor(143 × 0.7903) = 113 HP. The appraisal percentage is 45 ÷ 45 = 100%.
How to read the result
Each listed triple exactly reproduces the entered CP and HP at the selected level. IV percentage is the sum divided by 45, but that percentage is not a battle ranking. League optimization depends on evolved species, CP cap, level, moves, and matchup breakpoints.
