What is a Pokémon GO Calculator for IVs?
A calculator for Pokémon GO, specifically an IV (Individual Values) calculator, is a tool used to determine the hidden stats of a Pokémon. Every Pokémon in the game has three core IVs: Attack, Defense, and Stamina. Each of these values ranges from 0 to 15. These IVs are added to a Pokémon’s base stats to determine its final Combat Power (CP) and Hit Points (HP).
This calculator helps you reverse-engineer these hidden values based on the visible stats like CP, HP, and the stardust required to power up. Knowing your Pokémon’s IVs is crucial for players who want to excel in Gym battles, Raids, and the GO Battle League, as a Pokémon with higher IVs will have a higher maximum CP and better overall performance. A Pokémon with perfect 15/15/15 IVs is often called a “hundo” or 100% perfect.
The Formula Behind the Pokémon GO Calculator
The calculations for a Pokémon’s stats are complex and involve several components. The two primary formulas this calculator for Pokémon GO uses are for HP and CP.
HP Formula:
HP = floor((Base Stamina + Stamina IV) * CP_Multiplier)
CP Formula:
CP = floor(((Base Attack + Attack IV) * (Base Defense + Defense IV)^0.5 * (Base Stamina + Stamina IV)^0.5 * CP_Multiplier^2) / 10)
Here’s a breakdown of the variables used:
| 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. | 0-15 | 0-15 (Random on catch) |
| CP_Multiplier | A constant that scales with the Pokémon’s level. | Decimal | 0.094 (Lvl 1) to 0.84 (Lvl 50) |
Practical Examples
Understanding how the calculator works is best done with examples. Here are two common scenarios.
Example 1: A Wild Pikachu
- Inputs: Pokémon: Pikachu, CP: 400, HP: 55, Stardust Cost: 1900
- Calculator Analysis: Based on the 1900 stardust cost, the calculator determines the Pokémon’s level is likely between 15 and 16. It then tests all 4096 IV combinations (16x16x16) at these levels.
- Results: The calculator might find a few possible combinations, such as Level 15.5 with IVs of 12/14/13 (87% perfect) or Level 16 with IVs of 8/10/9 (60% perfect). This helps you decide if it’s worth investing stardust in.
Example 2: A Snorlax from a Raid
- Inputs: Pokémon: Snorlax, CP: 1650, HP: 170, Stardust Cost: 2500
- Calculator Analysis: A 2500 stardust cost indicates a level of 20 (the standard for raid bosses). Since Pokémon from raids have a minimum IV of 10 for each stat, the calculator only needs to check combinations from 10/10/10 to 15/15/15. You can learn more about this in our guide to pokemon go cp calculator.
- Results: The result will likely be very precise, for example, a single combination of 14/15/12 (91% perfect). This is a strong Pokémon worth powering up for Great League or Ultra League.
How to Use This Pokémon GO Calculator
Using our calculator is a simple, four-step process designed for accuracy.
- Select the Pokémon: Choose the correct Pokémon from the dropdown list. This is crucial as the calculator needs its unique base stats.
- Enter Visible Stats: Carefully input the Pokémon’s CP, HP, and the Stardust required for its next power-up. Double-check these numbers for accuracy.
- Indicate Power-Up Status: Select whether you have ever powered up the Pokémon. A Pokémon that hasn’t been powered up has fewer possible levels, leading to more accurate results.
- Calculate and Interpret: Click the “Calculate IVs” button. The tool will display a percentage range of perfection and a table of all possible IV combinations. A smaller range indicates a more certain result. To learn the basics check out our guide on how to calculate pokemon iv.
Key Factors That Affect Pokémon IVs
- Method of Encounter: Wild Pokémon have completely random IVs from 0-15.
- Weather Boosts: Pokémon caught with a weather boost have a minimum IV of 4 for each stat.
- Research & Raids: Pokémon from Field Research, Special Research, and Raids have a minimum IV of 10 for each stat (a 10/10/10 floor).
- Eggs: Pokémon hatched from eggs also have a 10/10/10 IV floor.
- Trading: When a Pokémon is traded, its IVs are completely re-rolled. The minimum IVs depend on your friendship level, with Best Friends having a 5/5/5 floor. This is a good way to try and get a better pokemon appraisal.
- Lucky Pokémon: A Pokémon that becomes Lucky through a trade has a guaranteed minimum IV of 12 for each stat (12/12/12 floor). This significantly increases the chance of getting a high-IV Pokémon.
- Shadow & Purified Pokémon: Purifying a Shadow Pokémon adds +2 to each of its IVs. A 13/13/13 Shadow Pokémon will become a 15/15/15 Purified one.
Frequently Asked Questions (FAQ)
1. What does IV percentage mean in this calculator for Pokémon GO?
The IV percentage represents how close your Pokémon is to “perfect.” It’s calculated by summing the Attack, Defense, and Stamina IVs and dividing by 45 (the maximum possible total of 15+15+15). A 100% Pokémon is a perfect 15/15/15.
2. Why does the calculator give a range of results?
Sometimes, different combinations of level and IVs can result in the same CP and HP. The calculator shows all possibilities. To narrow it down, you can use the in-game appraisal system or power up the Pokémon once and recalculate.
3. Is a 100% IV Pokémon always the best?
For Master League, raids, and gym defense, yes. However, for Great League and Ultra League (which have CP caps), the ideal IVs are often low Attack and high Defense/Stamina to maximize the Pokémon’s level under the CP limit.
4. Can I get a 0% IV Pokémon?
Yes, it’s possible to find a Pokémon with 0/0/0 IVs in the wild, though it’s extremely rare—even rarer than a 100% perfect one!
5. Does evolving a Pokémon change its IVs?
No, a Pokémon’s IVs are fixed and do not change upon evolution.
6. How does the “Powered Up” option help?
A Pokémon that has never been powered up can only be at a whole-number level (e.g., 20, 21). A powered-up Pokémon can also be at half-levels (e.g., 20.5, 21.5). Telling the calculator it hasn’t been powered up eliminates half the level possibilities, refining the results.
7. Where do I find the stardust cost?
Click on the Pokémon in your inventory. The “Power Up” button will show the required stardust and candy. This value is a key input for our calculator for Pokémon GO.
8. What is a perfect iv pokemon?
A perfect IV Pokémon, or “hundo,” has the maximum possible IVs: 15 in Attack, 15 in Defense, and 15 in Stamina. Our calculator will show this as a 100% perfection rating.
