How to Use the Pokémon GO IV Calculator
The Pokémon GO IV calculator narrows down the hidden stats of your Pokémon from the visible information on the capture screen — CP, HP, and stardust cost. Understanding IVs helps you decide which Pokémon to invest rare candies and stardust in.
Step 1: Find your Pokémon's stats
Open the Pokémon details screen. Note the CP shown at the top, the HP number, and tap the power-up button to see the stardust cost. Enter all three numbers along with your trainer level.
Step 2: Add your in-game appraisal
Tap the three-dots menu on the Pokémon screen and select "Appraise." Your team leader gives a verdict ranging from "Your Pokémon is a wonder!" (highest) to "Not great overall" (lowest). Adding this narrows the possible IV range significantly.
Step 3: Decide whether to invest stardust
A "Wonder" appraisal with high CP means 82-100% IVs — worth powering up for raids. For PvP (GO Battle League), check the IV breakpoints for your specific Pokémon at the CP cap — sometimes a lower IV combination creates a better stat product. The IV percentage alone doesn't tell the whole story for PvP.

What are IVs in Pokémon GO?
Individual Values (IVs) are hidden stats that add bonus points to a Pokémon's base attack, defense, and stamina. Each IV ranges from 0–15. A 15/15/15 Pokémon (100% IV) has the maximum possible stats for its species. IVs affect how strong a Pokémon can become when powered up.
Does IV percentage really matter?
For most players, IVs matter less than species and moveset. A 96% IV with the wrong fast move loses to an 80% IV with the correct moveset. For endgame PvE raids, top-level players prefer 98-100% IV, but the difference from 80% IV is only 2-5% damage output.
What is the best IV for PvP in GO Battle League?
PvP IVs are different from PvE IVs. In GO Battle League, lower IVs sometimes create better stat products at the CP cap. Many meta picks like Medicham and Bastiodon are optimal at 0/15/15 (0 attack, 15 defense, 15 stamina) in Great League. Use a dedicated GO Battle League IV calculator for PvP.
Why does the calculator show multiple possible IV combinations?
Because CP and HP round to whole numbers, multiple IV combinations can produce the same visible stats. The in-game Appraisal feature narrows it down. After appraising, check which IV ranges match all three pieces of information (highest stat, whether it's the best, and the range: Wonder/Excellent/Above Average).
