What is an iv pokemon calculator?

An iv pokemon calculator is a specialized tool used by Pokémon GO players to determine the hidden stats of their Pokémon. Every Pokémon has three Individual Values, or IVs: Attack, Defense, and Stamina. These values range from 0 to 15 for each stat and are added to the Pokémon’s base stats to determine its overall combat strength. Since these values are not directly visible in the game, a calculator uses known formulas to reverse-engineer them based on the Pokémon’s visible stats: Combat Power (CP), Hit Points (HP), and Level. Understanding these values is crucial for players who want to optimize their teams for raids, gym battles, and Player vs. Player (PvP) leagues.

The iv pokemon calculator Formula and Explanation

The core of an iv pokemon calculator relies on two main formulas: one for Combat Power (CP) and one for Hit Points (HP). The calculator iterates through all 4,096 possible IV combinations (16x16x16) for a given Pokémon, calculates the CP and HP for each, and presents the combinations that match the user’s input.

The formulas are as follows:

CP = floor((Base Attack + Attack IV) * (Base Defense + Defense IV)^0.5 * (Base Stamina + Stamina IV)^0.5 * CPM^2 / 10)

HP = floor((Base Stamina + Stamina IV) * CPM)

This calculator uses these precise formulas to find every possible match for your Pokémon.

Variables Table

An explanation of the variables used in the Pokémon IV calculation.

Variable	Meaning	Unit / Range	Typical Range
Base Stats	The inherent Attack, Defense, and Stamina for a Pokémon species.	Unitless Integer	~50 to ~300
IVs	Individual Values for Attack, Defense, and Stamina.	Unitless Integer	0 – 15
CPM	CP Multiplier. A constant determined by the Pokémon’s level.	Decimal	~0.09 to ~0.8
CP / HP	The final Combat Power and Hit Points displayed in-game.	Unitless Integer	10 – 5000+

Practical Examples

Example 1: High-Level Dragonite

A player wants to check their Dragonite, which they have powered up significantly.

• Inputs: Pokémon: Dragonite, CP: 3500, HP: 170, Level: 40
• Results: The calculator might find a single combination, such as 15 Attack / 14 Defense / 15 Stamina.
• Interpretation: This is a 98% perfect Dragonite, an excellent attacker for raids and gym battles. You can learn more about raid battle strategies on our blog.

Example 2: Great League Pikachu

A player has a Pikachu they want to use in the Great League, which has a 1500 CP cap.

• Inputs: Pokémon: Pikachu, CP: 1498, HP: 115, Level: 27.5
• Results: The calculator may return several combinations, for example: 0/15/14, 1/13/15, etc.
• Interpretation: In PvP, low Attack and high Defense/Stamina IVs are often preferred. The 0/15/14 would be the ideal choice here. For more tips, see our guide on the best pokemon for pvp.

Key Factors That Affect Pokémon IVs

• How You Obtained It: Pokémon from Raids, Field Research, and Eggs are guaranteed to have minimum IVs of 10/10/10.
• Trading: Trading Pokémon re-rolls their IVs. The new IVs have a floor based on your Friendship Level with the other trainer. A “Lucky Trade” guarantees at least 12/12/12 IVs.
• Weather Boost: Wild Pokémon caught with a weather boost have a minimum IV floor of 4/4/4.
• Purification: Purifying a Shadow Pokémon adds +2 to each IV stat, up to a maximum of 15. Check our shadow pokemon guide for more info.
• Species Base Stats: A high-IV Pokémon with low base stats (like a perfect Shuckle) will still have a much lower CP than a low-IV Pokémon with high base stats (like a 0% Dragonite).
• Game Balance Updates: Occasionally, the game developers update the base stats of Pokémon, which can affect their overall power and ranking. Our pokemon stats explained article covers this in more detail.

Frequently Asked Questions (FAQ)

What is a “perfect” Pokémon?

A perfect Pokémon has the maximum possible IVs for each stat: 15 Attack, 15 Defense, and 15 Stamina. This is often referred to as 100% or a “hundo”.

Are 100% IVs always the best?

Not always. For Master League and raids, 100% IVs are ideal. However, for Great and Ultra Leagues (with CP caps), Pokémon often perform better with low Attack IVs and high Defense/Stamina IVs, which allows them to reach a higher level without exceeding the CP limit.

How does the in-game appraisal system work?

The in-game appraisal shows you the IVs using a bar chart and star ratings. A 3-star rating means the Pokémon has high total IVs, and a red stamp indicates it’s perfect (100%).

What does “IV floor” mean?

An IV floor is the minimum possible IV a Pokémon can have when obtained through certain methods. For example, a Pokémon from a raid has an IV floor of 10 for each stat.

Why does the calculator give multiple results?

At lower levels, different IV combinations can result in the same CP and HP. To narrow down the results, you can power up the Pokémon once and re-enter its new stats into the iv pokemon calculator.

Is this calculator safe to use?

Yes. This calculator is entirely web-based and does not require you to log in to your Pokémon GO account, making it 100% safe and compliant with the game’s terms of service.

Can IVs change?

Normally, a Pokémon’s IVs are permanent. The only ways they change are through trading (which completely re-rolls them) or by purifying a Shadow Pokémon.

What is a ‘Shundo’?

A ‘Shundo’ is a fan term for a Pokémon that is both Shiny and has perfect 100% IVs. It is one of the rarest and most sought-after types of Pokémon.
