Use the most accurate Pokémon Go IV Calculator to determine the hidden Individual Values (IVs) of your Pokémon. By inputting the essential stats—CP, HP, Base Stats, and the CP Multiplier—you can find the precise Attack, Defense, and Stamina IVs (0-15) that define your Pokémon’s potential.
Pokémon Go IV Calculator
Detailed IV Calculation Steps
Target HP Multiplier: N/A
The calculator iterates through all 4096 possible IV combinations (0/0/0 to 15/15/15) to find all sets (Attack/Defense/Stamina) that match the provided CP and HP within a negligible margin of error.
Pokémon Go IV Calculator Formula
The calculation of Individual Values (IVs) is an inverse process based on the known formulas for Combat Power (CP) and Health Points (HP). We search for the hidden IVs (Attack, Defense, Stamina, each 0-15) that satisfy both equations simultaneously.
HP = (BaseStamina + Stamina IV) * CP Multiplier (CPM)
CP = MAX(10, ROUND((BaseAttack + Attack IV) * SQRT(BaseDefense + Defense IV) * SQRT(BaseStamina + Stamina IV) * (CPM^2) / 10))

Variables Explained
To use the calculator, you need six specific inputs:
- Current Combat Power (CP): The numerical value shown on your Pokémon’s summary screen.
- Current Health Points (HP): The numerical HP value shown. This is crucial for isolating the Stamina IV.
- Base Attack/Defense/Stamina Stats: These are species-specific values published in the game master file. You must look up the correct base stats for your specific Pokémon.
- CP Multiplier (CPM): This value directly correlates with your Pokémon’s current Level (power-up stage). It must be determined from a CPM chart based on the Stardust cost or level.
What are Pokémon Go IVs?
Individual Values (IVs) are hidden stats in Pokémon Go that range from 0 to 15 for Attack, Defense, and Stamina. These values are permanent for a captured Pokémon and are added to the Pokémon’s Base Stats, significantly impacting its maximum potential Combat Power (CP) and Health Points (HP). A perfect Pokémon, often called a “hundo,” has 15/15/15 IVs.
IVs are critical for competitive play. For raids and Master League PvP, perfect 15/15/15 IVs are generally preferred for maximum CP output. However, for Great League and Ultra League PvP, a low Attack IV and high Defense/Stamina IVs are often optimal to maximize bulk while staying under the league’s CP cap.
Knowing your Pokémon’s IVs is the first step toward deciding whether to invest Stardust and Candy into powering up the Pokémon for battles.
How to Calculate Pokémon Go IVs (Example)
Here is a simplified step-by-step example of how the IV calculation is conceptually performed:
- Determine CPM & Base Stats: Identify the Pokémon’s Level (and thus its CPM) and its Base Attack (240), Defense (181), and Stamina (219) stats from external game data.
- Isolate Stamina IV: Use the HP formula: $HP = (BaseS + S) \cdot CPM$. Since HP, BaseS, and CPM are known, the calculator can solve for the effective $S$ (Stamina IV). For example, if $HP=150$, $BaseS=219$, and $CPM=0.7903$, the ideal effective Stamina Stat is $150 / 0.7903 \approx 189.79$. The Stamina IV must be an integer (0-15) that, when added to BaseS, gets closest to this value.
- Search Attack/Defense Combinations: With the Stamina IV narrowed down, the calculator loops through all 256 combinations of Attack and Defense IVs (0-15).
- Verify CP Match: For each A/D/S combination, the expected CP is calculated using the full CP formula. Only the combinations that produce the observed CP value (within a tolerance of +/- 1) are considered valid.
- Display Range: The output will show all valid A/D/S combinations found, allowing the user to see the minimum and maximum possible Total IV Percentages.
Frequently Asked Questions (FAQ)
Is the CP Multiplier the same as the Pokémon’s Level?
No, the CP Multiplier (CPM) is a decimal value (e.g., 0.7317) that is *derived* from the Pokémon’s Level (e.g., Level 29.5). The CPM is the actual value used in the CP and HP formulas, while the Level is a whole or half integer (1 to 50).
Why does the calculator sometimes show a range of IVs instead of just one result?
Due to the rounding involved in the final CP calculation, multiple IV combinations can sometimes result in the exact same displayed CP and HP at a specific Level. The calculator accurately reports all mathematically possible IV combinations.
What is the maximum possible Total IV Percentage?
The maximum total IV points is 45 (15 Attack + 15 Defense + 15 Stamina). This is often represented as a 100% IV, or a “hundo.”
Can I use this calculator without knowing the Base Stats?
No. The Base Attack, Base Defense, and Base Stamina are unique to each Pokémon species and are essential constants in the CP and HP formulas. You must look up these values (e.g., on a Pokémon database website) before using the calculator.
