What is a purify pokemon calculator?

A purify pokemon calculator is a specialized tool for players of Pokémon GO to predict the outcome of purifying a Shadow Pokémon. When you rescue a Shadow Pokémon from Team GO Rocket, it has suppressed stats and a powerful “Shadow Bonus” (20% extra damage dealt, 20% more damage taken). Purifying it removes this bonus but provides several permanent benefits. This calculator precisely determines what those benefits will be for your specific Pokémon.

Instead of guessing, you can use this calculator to see the exact Individual Values (IVs) and Combat Power (CP) your Pokémon will have after you spend the required Stardust and Candy. This is crucial for making informed decisions on whether a particular Shadow Pokémon is worth the investment. Is it better to keep the raw power of a Shadow Pokémon or get a high-IV, cheaper-to-power-up Purified Pokémon? This tool helps you answer that question.

The purify pokemon calculator Formula and Explanation

The mechanics of purification are straightforward, but the impact on Combat Power requires a specific formula. Our purify pokemon calculator automates this for you.

  1. IV Increase: Each of the three IVs (Attack, Defense, and Stamina) is increased by 2. The maximum for any IV is 15.
  2. Level Increase: The Pokémon’s level is automatically set to 25.
  3. CP Recalculation: The Pokémon’s CP is recalculated based on its new, higher IVs and its new level.

The core CP formula is:

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

Variables Table

Variable Meaning Unit / Range Typical Range
Base Stats The Pokémon species’ inherent Attack, Defense, and Stamina. Unitless Integer ~50 – ~300
IVs (Individual Values) Your specific Pokémon’s genetic potential. Unitless Integer 0 – 15
CPM (CP Multiplier) A constant based on the Pokémon’s level. For purification, we use the Level 25 value. Decimal 0.667934 (for Level 25)
CP (Combat Power) The final calculated strength of the Pokémon. Unitless Integer 10 – 5000+

Practical Examples

Example 1: A Promising Shadow Dratini

A player catches a Shadow Dratini and its appraisal shows its IVs are 13 for Attack, 11 for Defense, and 14 for Stamina.

  • Inputs: Pokémon: Dratini, IVs: 13 / 11 / 14
  • Calculation:
    • New Attack: 13 + 2 = 15
    • New Defense: 11 + 2 = 13
    • New Stamina: 14 + 2 = 15
  • Results: The calculator would show a purified Dratini with perfect 15/13/15 IVs. Given Dratini’s final evolution, Dragonite, is very powerful, purifying to get a high-IV version is a strong consideration, especially if you lack a good non-shadow one.

Example 2: A Common Shadow Zubat

A player has a Shadow Zubat with low IVs: 4 Attack, 7 Defense, 5 Stamina.

  • Inputs: Pokémon: Zubat, IVs: 4 / 7 / 5
  • Calculation:
    • New Attack: 4 + 2 = 6
    • New Defense: 7 + 2 = 9
    • New Stamina: 5 + 2 = 7
  • Results: The purified Zubat would have 6/9/7 IVs. While better, these are still not great. Since Zubat’s purification cost is low (1,000 Stardust), a player might do this simply to advance their “Purifier” medal, but not for creating a strong battle Pokémon.

Key Factors That Affect purify pokemon calculator Results

  • Starting IVs: The most important factor. A Shadow Pokémon with IVs of 13/13/13 or higher is guaranteed to become a 100% perfect IV Pokémon upon purification.
  • Pokémon Species: A Pokémon’s base stats determine its ultimate potential. A 100% IV Magikarp will have a much higher CP when evolved to Gyarados than a 100% IV Pidgey.
  • Purification Cost: Costs vary. Common Pokémon like Rattata cost 1,000 Stardust, starters like Mudkip cost 3,000, and rare/powerful ones like Dratini cost 5,000. Legendary Pokémon cost even more. This resource cost is a major consideration.
  • Player’s Goal (PvE vs. PvP): For raids (PvE), the 20% damage boost of a Shadow Pokémon is often superior to the stats of a Purified one, even with 0% IVs vs 100% IVs. However, for PvP, the extra bulk and different CP calculations can make Purified Pokémon viable, especially in CP-capped leagues.
  • Mega Evolutions: Shadow Pokémon cannot Mega Evolve. If you want a high-IV Pokémon for its Mega form (e.g., Swampert, Tyranitar), you *must* purify it first. This makes purifying high-IV shadows of Mega-capable species very valuable. See our Mega Evolution guide.
  • Stardust and Candy Savings: Purified Pokémon enjoy a discount on powering up and learning a second charge move. This can save you tens of thousands of Stardust in the long run.

Frequently Asked Questions (FAQ)

1. Is it always better to purify a Shadow Pokémon?

No. For pure damage output in raids, a 0% IV Shadow Pokémon will out-damage a 100% IV non-Shadow version of the same species. The decision depends on your goal: raw power (Shadow) vs. cost-efficiency and potential for perfection/Mega Evolution (Purified).

2. What happens if my Pokémon’s IV is 14 or 15?

The IV will become 15. The +2 bonus does not go “over” the cap. A 14 Attack becomes 15, and a 15 Attack stays 15.

3. Can I use this purify pokemon calculator for any Pokémon?

This calculator is designed for Pokémon that are available as Shadow Pokémon in Pokémon GO. If a Pokémon cannot be caught in its Shadow form, the concept of purification doesn’t apply.

4. Why does the calculator set the level to 25?

This is a fixed game mechanic. Regardless of the level you catch the Shadow Pokémon at (usually Level 8 or 13), it will always jump to Level 25 upon purification.

5. Does purifying change the moves?

Yes. The charged move “Frustration” is replaced by “Return”. “Return” is a Normal-type move that can be TMed away, but only during certain Team GO Rocket events can “Frustration” be removed.

6. Is a 100% IV Purified Pokémon better than a 100% IV normal Pokémon?

They are identical in stats and performance. The only difference is the Purified Pokémon has a slight visual aura, a lower power-up cost, and a “Purified” badge in your Pokédex.

7. Does the purify pokemon calculator account for weather boosts?

Yes, indirectly. A weather-boosted Shadow Pokémon is caught at a higher level and has a minimum IV floor of 4/4/4. You simply input those starting IVs (e.g., 4 or higher) into the calculator to see the result.

8. Where do I find my Pokémon’s IVs?

In Pokémon GO, select your Pokémon, tap the menu in the bottom right, and choose “Appraise”. Your team leader will show you the stats as three bars. Each bar is divided into three sections, representing 0-5, 6-10, and 11-15. You can estimate the exact number from the bar’s length.
