Use the ultimate **Pokémon GO IV Calculator** to determine the hidden Individual Values (IVs) of your Pokémon, unlocking its true potential for battles in the Great, Ultra, and Master Leagues. IVs range from 0 to 15 for Attack, Defense, and Stamina.

Pokémon GO IV Calculator Formula
The Combat Power (CP) and Hit Points (HP) formulas are fundamental to reverse-engineer a Pokémon’s IVs (Individual Values). Since the calculator does not know the exact Power Up Level (CPM), it iterates through possible levels and IV combinations that satisfy both equations:
$$CP = \frac{10 \times (\text{Base}_{ATK} + IV_{ATK}) \times \sqrt{\text{Base}_{DEF} + IV_{DEF}} \times \sqrt{\text{Base}_{STA} + IV_{STA}} \times CPM^2}{10}$$
$$HP = (\text{Base}_{STA} + IV_{STA}) \times CPM$$
Where $IV \in [0, 15]$ and $CPM$ (Combat Power Multiplier) is determined by the Pokémon’s current level, which is estimated from the **Stardust Cost**.

Variables Explained
- Pokémon Species: Required to fetch the **Base ATK, DEF, and STA** stats, which are used as the foundation for the IV calculation.
- Current Combat Power (CP): The observed primary metric, heavily influenced by the ATK IV and CPM.
- Current Hit Points (HP): The observed health stat, directly dependent on the STA IV and CPM.
- Stardust Cost to Power Up: The most crucial input for leveling, as it accurately determines the narrow range of possible Power Up Levels (CPM) the Pokémon could currently be at.
What is the Pokémon GO IV Calculator?
The Pokémon GO IV Calculator is an essential tool for competitive players. IVs (Individual Values) are three hidden statistics—Attack, Defense, and Stamina—each ranging from 0 to 15. A perfect Pokémon has 15/15/15 IVs, often referred to as a “hundo” or 100% IVs. These values are added to a Pokémon’s base stats before the Combat Power (CP) calculation.
Because the game does not display a Pokémon’s exact level (only a semi-circle indicator) and does not display the IVs, players must use the observed values (CP and HP) and the known game constants (Base Stats, Stardust/Level table) to reverse-engineer the IVs. The calculator performs thousands of checks in seconds to find which combination of Level and IVs mathematically match the inputs.
How to Calculate Pokémon GO IVs (Example)
- Input Data: Open your Pokémon’s summary screen and note down its species, Current CP, Current HP, and the Stardust cost shown next to the “Power Up” button (e.g., 5000 Stardust).
- Determine Level Range: The calculator uses the 5000 Stardust cost to look up the possible Combat Power Multiplier (CPM) values, typically narrowing the Level to between 25 and 28.
- Iterative Search: The system takes the known Base Stats for the species and runs a loop, testing every combination of Attack (0-15), Defense (0-15), and Stamina (0-15) IVs against every Level within the determined range.
- Match Validation: Only IV combinations that produce a CP *and* HP that exactly match the input values are considered valid.
- Final Output: The calculator will present the possible range of IVs (e.g., 10-15/10-15/10-15) and the overall percentage, which represents the IV floor and ceiling.

Frequently Asked Questions (FAQ)
Is a 100% IV Pokémon always better?
No. While 100% IVs are ideal for the Master League, the Great League (CP capped at 1500) and Ultra League (CP capped at 2500) often prefer low Attack IVs (e.g., 0/15/15) to achieve a higher total stat product under the CP cap.
Why does the calculator sometimes give a range of IVs?
This happens because multiple combinations of Level and IVs can result in the exact same CP and HP values. Providing the Stardust cost helps narrow this down significantly, but sometimes an exact match is impossible without the in-game Appraisal system.
Are IVs the same as Base Stats?
No. Base Stats are fixed for the Pokémon species (e.g., all Mewtwo have the same Base Stats). IVs (Individual Values) are the unique, random values (0-15) added to the Base Stats when the Pokémon is caught or hatched.
How accurate is this calculator?
This calculator relies on accurate inputs of CP, HP, and Stardust. If these values are entered correctly, the range provided is mathematically certain, as it checks all possible combinations against the known game formulas. It is highly accurate for finding the true potential IV range.
