Calculation Results
How the Pokémon Go IV Calculator Works:
This Pokémon Go IV Calculator estimates your Pokémon’s Individual Values (IVs) by iterating through all 4096 possible Attack, Defense, and Stamina IV combinations (0-15 for each). For each combination, it calculates the theoretical CP and HP at the given Pokémon Level, using a set of generic base stats. It then identifies which IV combinations match your Pokémon’s actual CP and HP. The results show the range of possible IVs and the overall IV percentage based on these matches.
Note: Without knowing the exact Pokémon species’ base stats, this calculator uses generic base stats for estimation. For precise results, use an in-game appraisal or a species-specific calculator.
What is a Pokémon Go IV Calculator?
A Pokémon Go IV Calculator is an essential tool for trainers looking to understand the hidden potential of their Pokémon. In Pokémon Go, every Pokémon has three hidden stats known as Individual Values (IVs): Attack, Defense, and Stamina. These values range from 0 to 15 for each stat, adding directly to a Pokémon’s base stats. While two Pokémon of the same species and level might have identical Combat Power (CP) and Hit Points (HP) on the surface, their underlying IVs can be vastly different, leading to significant performance variations in battles.
The primary purpose of a Pokémon Go IV Calculator is to reverse-engineer these hidden IVs based on observable stats like CP, HP, and the Pokémon’s current level. Since IVs are not directly displayed in the game, trainers rely on these calculators to get a precise understanding of their Pokémon’s genetic potential.
Who Should Use a Pokémon Go IV Calculator?
- Competitive Players: For those serious about PvP (Player vs. Player) battles or maximizing raid damage, understanding IVs is crucial. Specific IV spreads are optimal for different battle leagues (e.g., low Attack IVs for Great League PvP).
- Collectors: Many trainers aim to collect “perfect” 100% IV Pokémon, often referred to as “hundos.” A Pokémon Go IV Calculator helps identify these rare specimens.
- Resource Optimizers: Stardust and Candy are precious resources. Using a Pokémon Go IV Calculator helps trainers decide which Pokémon are worth investing in for powering up and evolving, ensuring resources are spent on Pokémon with high potential.
- Casual Players: Even casual players can benefit from knowing their Pokémon’s IVs to make informed decisions about which Pokémon to keep, trade, or transfer.
Common Misconceptions About Pokémon Go IVs
- IVs are Visible: A common misconception is that IVs are directly visible. They are not; only the in-game appraisal system gives hints, which a Pokémon Go IV Calculator then refines.
- CP/HP Alone Tell the Story: High CP or HP doesn’t automatically mean high IVs. A high-level Pokémon with poor IVs can have higher CP than a low-level Pokémon with perfect IVs.
- IVs Can Be Changed: Once a Pokémon is caught or hatched, its IVs are fixed and cannot be changed (except for Shadow Pokémon becoming Purified, which adds +2 to each IV).
- Higher IVs are Always Better: While generally true for raids and gym defense, in certain PvP leagues (like Great and Ultra League), specific lower Attack IVs can be optimal to maximize bulk.
Pokémon Go IV Calculator Formula and Mathematical Explanation
The core of any Pokémon Go IV Calculator lies in the formulas that determine a Pokémon’s Combat Power (CP) and Hit Points (HP). These formulas combine a Pokémon’s base stats (inherent to its species), its Individual Values (IVs), and a CP Multiplier (CPM) based on its level.
The Formulas:
The formulas used to calculate CP and HP are as follows:
- CP Formula:
CP = ((Base_Attack + Attack_IV) * Math.sqrt(Base_Defense + Defense_IV) * Math.sqrt(Base_Stamina + Stamina_IV) * Math.pow(CPM, 2)) / 10;
(The result is then rounded down to the nearest integer.) - HP Formula:
HP = Math.floor((Base_Stamina + Stamina_IV) * CPM);
Our Pokémon Go IV Calculator works by reversing this process. Since we know the observed CP, HP, and the Pokémon’s Level (which gives us the CPM), the calculator iterates through all 4096 possible combinations of Attack, Defense, and Stamina IVs (0-15 for each). For each combination, it calculates the theoretical CP and HP using the formulas above and a set of generic base stats. If the calculated CP and HP match the user’s input (within a small tolerance for CP due to rounding), that IV combination is considered a possible match.
The calculator then compiles all matching IV combinations to determine the minimum and maximum possible values for Attack, Defense, and Stamina IVs, as well as the overall IV percentage range. This iterative process allows the Pokémon Go IV Calculator to narrow down the hidden IVs.
Variables Explanation:

Practical Examples (Real-World Use Cases)
Let’s walk through a couple of examples using the Pokémon Go IV Calculator to illustrate how it helps trainers make decisions.
Example 1: A Strong Raid Attacker Candidate
Imagine you just caught a powerful Machamp, a top-tier Fighting-type attacker, and you want to know if it’s worth investing Stardust and Candy into. You check its stats:
- Pokémon CP: 2850
- Pokémon HP: 145
- Pokémon Level: 35 (estimated from Stardust cost to power up)
You input these values into the Pokémon Go IV Calculator. The calculator processes the data and provides the following results:
- Estimated IV Percentage: 91.1% – 97.8%
- Possible Attack IV Range: 14-15
- Possible Defense IV Range: 13-15
- Possible Stamina IV Range: 13-15
- Number of Possible IV Combinations: 8
Interpretation: These results indicate that your Machamp has excellent IVs, particularly in Attack, which is crucial for a raid attacker. An IV percentage in the 90s is highly desirable. With a high Attack IV, this Machamp is a prime candidate for powering up to its maximum potential, making it a formidable force in raids against Dark, Ice, Normal, Rock, and Steel-type Pokémon. The narrow range of possible IVs gives you high confidence in its strength.
Example 2: A Potential PvP Pokémon for Great League
You’ve caught a Swampert, a popular choice for the Great League (CP cap 1500), and you want to see if its IVs are suitable. You note its stats:
- Pokémon CP: 1498
- Pokémon HP: 130
- Pokémon Level: 20 (estimated from Stardust cost)
After entering these into the Pokémon Go IV Calculator, you get:
- Estimated IV Percentage: 75.6% – 84.4%
- Possible Attack IV Range: 0-5
- Possible Defense IV Range: 13-15
- Possible Stamina IV Range: 13-15
- Number of Possible IV Combinations: 12
Interpretation: For Great League PvP, a low Attack IV combined with high Defense and Stamina IVs is often preferred. This is because Attack IV contributes more to CP than Defense or Stamina IVs. By having a lower Attack IV, the Pokémon can reach a higher level (and thus gain more bulk from its base stats) while staying under the 1500 CP cap. The results from the Pokémon Go IV Calculator show a very low Attack IV range and high Defense/Stamina, making this Swampert an excellent candidate for Great League PvP. Despite the overall IV percentage not being “100%”, this specific IV spread is highly desirable for its intended purpose.
How to Use This Pokémon Go IV Calculator

Key Factors That Affect Pokémon Go IV Calculator Results
The accuracy and range of results from a Pokémon Go IV Calculator are influenced by several critical factors. Understanding these can help you get the most precise estimates for your Pokémon.
-
Pokémon Level
The Pokémon’s level is paramount. The CP Multiplier (CPM) scales with level, directly impacting CP and HP. A small error in estimating the Pokémon’s level can lead to a significantly different IV range from the Pokémon Go IV Calculator. For instance, a Pokémon at Level 20 will have different CP/HP values for the same IVs compared to one at Level 20.5. Always try to determine the level as accurately as possible, often by using the Stardust cost to power up as a guide.
-
Base Stats of the Pokémon Species
Every Pokémon species has unique base stats for Attack, Defense, and Stamina. These base stats are the foundation upon which IVs are added. Our generic Pokémon Go IV Calculator uses average base stats for estimation. However, a Pokémon with naturally high base Attack (like Rampardos) will have its CP and HP influenced differently by IVs than a Pokémon with high base Stamina (like Blissey). For the most precise IV calculation, a species-specific calculator that incorporates exact base stats is ideal, but our tool provides a strong general estimate.
-
CP and HP Values
These are your direct inputs into the Pokémon Go IV Calculator. Even a slight difference in CP or HP can drastically alter the possible IV combinations. Always double-check these values from your in-game Pokémon summary. Rounding in the CP formula means that sometimes a single CP value can correspond to multiple IV combinations, leading to a range of possible IVs.
-
In-Game Appraisal System
The in-game appraisal system, provided by your team leader, offers valuable clues about your Pokémon’s IVs. It gives an overall IV percentage tier (e.g., “Amazing,” “Strong,” “Decent”) and highlights the best individual stats, often with a numerical range (e.g., “15,” “13-14”). While our Pokémon Go IV Calculator doesn’t directly take these as inputs, using the appraisal to narrow down your expectations for the IV ranges can help you interpret the calculator’s output more effectively.
-
Weather Boost
Pokémon caught in the wild during weather that boosts their type will have a higher minimum level (Level 6 instead of 1) and can be caught at higher levels (up to Level 35 instead of 30). This affects the initial level of the Pokémon you’re evaluating. If you catch a weather-boosted Pokémon, ensure you accurately determine its level before using the Pokémon Go IV Calculator.
-
Shadow and Purified Status
Shadow Pokémon have a 20% Attack boost and a 20% Defense reduction, while Purified Pokémon gain +2 to each IV. These modifiers fundamentally change how their stats are calculated. If you’re evaluating a Shadow or Purified Pokémon, remember that their effective stats are different, and a standard Pokémon Go IV Calculator might need adjustments or a specific version to account for these unique mechanics.
Frequently Asked Questions (FAQ)
What are IVs in Pokémon Go?
IVs (Individual Values) are hidden stats for Attack, Defense, and Stamina that range from 0 to 15 for each stat. They are unique to each Pokémon and add directly to its base stats, determining its overall strength and potential.
How do IVs affect my Pokémon?
IVs significantly impact a Pokémon’s maximum CP, HP, and overall performance in battles. Higher IVs generally mean a stronger Pokémon, especially for raids and gym defense. For PvP, specific IV spreads (e.g., low Attack, high Defense/Stamina) can be optimal for certain leagues.
Can I change a Pokémon’s IVs?
No, a Pokémon’s IVs are fixed once it’s caught or hatched. The only exception is Purified Pokémon, which receive a +2 boost to each IV after being purified from a Shadow Pokémon.
What’s a good IV percentage?
For general purposes (raids, gym defense), an IV percentage of 80% or higher is considered very good, with 100% being perfect. For PvP, “good” IVs can vary greatly depending on the league and Pokémon species, often favoring lower Attack IVs to maximize bulk.
Why does the Pokémon Go IV Calculator give a range?
The calculator often provides a range of possible IVs because multiple IV combinations can sometimes result in the same observed CP and HP at a given level, especially due to the rounding in the CP formula. The more precise your inputs (especially level), the narrower the range will be.
How do I find my Pokémon’s level?
Pokémon Go does not directly display a Pokémon’s level. You can estimate it by observing the Stardust cost to power up your Pokémon. Each Stardust cost corresponds to a specific level range. For example, 1000 Stardust means levels 15-20. You can also use the in-game appraisal system to get a general idea of its level range.
Is this Pokémon Go IV Calculator accurate without knowing the species?
This Pokémon Go IV Calculator uses generic base stats for estimation, making it a good general tool. For the most precise results, knowing the specific Pokémon species’ base stats is crucial. However, it provides a very strong estimate and narrows down possibilities significantly.
What’s the difference between IVs and EVs (from main series games)?
IVs (Individual Values) in Pokémon Go are fixed at capture/hatch and represent a Pokémon’s inherent genetic potential. EVs (Effort Values) from the main series Pokémon games are gained through battling specific Pokémon and can be trained to boost stats. Pokémon Go does not have an EV system.
