What is a Pokémon Go Purify Calculator?

A Pokémon Go Purify Calculator is an essential tool for trainers looking to optimize their Shadow Pokémon. In Pokémon Go, Shadow Pokémon are special variants that have higher attack stats but lower defense, and they come with the charged attack “Frustration.” Purifying a Shadow Pokémon removes “Frustration,” replaces it with “Return,” boosts its IVs (Individual Values) by +2 for Attack, Defense, and HP, and reduces the Stardust and Candy costs for powering up and learning new attacks.

This calculator helps you determine the exact IVs your Shadow Pokémon will have after purification, along with the associated Stardust and Candy costs. It allows you to weigh the benefits of a purified Pokémon (higher IVs, cheaper power-ups, “Return” move) against the unique power of a Shadow Pokémon (1.2x attack bonus).

Who Should Use the Pokémon Go Purify Calculator?

• Competitive Players: To decide if a Shadow Pokémon with low IVs is worth purifying for a perfect or near-perfect IV spread, especially for Master League PvP or specific raid counters.
• Resource Managers: To understand the Stardust and Candy investment required, helping them prioritize which Pokémon to purify based on their current resources.
• Collectors: To identify which Shadow Pokémon can become 100% IV (hundo) after purification, adding valuable Pokémon to their collection.
• New Trainers: To learn the mechanics of purification and make smart early-game decisions without wasting precious resources.

Common Misconceptions About Purifying Pokémon

• “Purified Pokémon are always better than Shadow Pokémon”: Not true. While purified Pokémon have higher IVs and cheaper power-ups, Shadow Pokémon retain a significant 20% attack bonus, making them superior attackers in many raid and gym scenarios, even with lower IVs.
• “Purifying removes all value”: False. Purifying can be beneficial for Pokémon that are more useful for their bulk (e.g., some PvP Pokémon where the Shadow attack bonus isn’t as critical) or for those that become perfect IVs, making them excellent for Mega Evolutions or specific niche uses.
• “Purification costs are fixed for all Pokémon”: Incorrect. The Stardust and Candy costs vary significantly by Pokémon species, with common Pokémon costing less and Legendaries costing much more. Our Pokémon Go Purify Calculator accounts for these variable costs.

Pokémon Go Purify Calculator Formula and Mathematical Explanation

The core of the Pokémon Go Purify Calculator lies in understanding how IVs are affected by the purification process and the associated costs. The calculation is straightforward but crucial for strategic gameplay.

Step-by-Step Derivation:

1. Individual IV Boost: For each of the three IVs (Attack, Defense, HP), the value is increased by 2.
2. IV Cap: The maximum IV for any stat is 15. If the current IV plus 2 exceeds 15, it is capped at 15.
   • Purified Attack IV = MIN(Shadow Attack IV + 2, 15)
   • Purified Defense IV = MIN(Shadow Defense IV + 2, 15)
   • Purified HP IV = MIN(Shadow HP IV + 2, 15)
3. Total Purified IV Sum: The sum of the three new purified IVs.
   • Total Purified IV Sum = Purified Attack IV + Purified Defense IV + Purified HP IV
4. Overall IV Percentage: This represents how “perfect” the Pokémon is after purification. The maximum possible IV sum is 45 (15 Attack + 15 Defense + 15 HP).
   • Purified IV Percentage = (Total Purified IV Sum / 45) * 100%
5. Resource Costs: The Stardust and Candy costs are direct inputs, as they are specific to each Pokémon species and are not calculated by the tool but rather provided by the user based on in-game information.

Variables Table:

Variable	Meaning	Unit	Typical Range
Shadow Attack IV	Individual Value for Attack before purification	Points	0 – 15
Shadow Defense IV	Individual Value for Defense before purification	Points	0 – 15
Shadow HP IV	Individual Value for HP before purification	Points	0 – 15
Purify Stardust Cost	Stardust required to purify the Pokémon	Stardust	1,000 – 20,000
Purify Candy Cost	Candy required to purify the Pokémon	Candy	1 – 20
Purified Attack IV	Individual Value for Attack after purification	Points	2 – 15
Purified Defense IV	Individual Value for Defense after purification	Points	2 – 15
Purified HP IV	Individual Value for HP after purification	Points	2 – 15
Total Purified IV Sum	Sum of all three IVs after purification	Points	6 – 45
Purified IV Percentage	Overall perfection percentage after purification	%	~13.3% – 100%

Practical Examples (Real-World Use Cases)

Let’s look at a few scenarios where the Pokémon Go Purify Calculator can help you make smart decisions.

Example 1: Turning a Low IV Shadow into a Hundo

Scenario: Shadow Machop with 13/13/13 IVs

You caught a Shadow Machop with IVs of 13 Attack, 13 Defense, and 13 HP. Machop’s purification cost is typically 3,000 Stardust and 3 Candy. You want to know if it can become a perfect 15/15/15 Pokémon.

• Inputs:
  • Shadow Attack IV: 13
  • Shadow Defense IV: 13
  • Shadow HP IV: 13
  • Stardust Cost: 3,000
  • Candy Cost: 3
• Outputs (from calculator):
  • Purified Attack IV: MIN(13 + 2, 15) = 15
  • Purified Defense IV: MIN(13 + 2, 15) = 15
  • Purified HP IV: MIN(13 + 2, 15) = 15
  • Total Purified IV Sum: 15 + 15 + 15 = 45
  • Purified IV Percentage: (45 / 45) * 100% = 100%
  • Stardust Cost: 3,000
  • Candy Cost: 3

Interpretation: This Shadow Machop is an excellent candidate for purification! For a relatively low cost, you can obtain a perfect IV Machamp, which is fantastic for raids, gyms, and even some PvP leagues (though Shadow Machamp is often preferred for its raw damage output). This is a clear win for purification if you prioritize perfect IVs or need a cheaper-to-power-up Machamp.

Example 2: Evaluating a High IV Shadow Legendary

Scenario: Shadow Mewtwo with 10/10/10 IVs

You caught a Shadow Mewtwo with IVs of 10 Attack, 10 Defense, and 10 HP. Legendary Shadow Pokémon have a high purification cost, typically 20,000 Stardust and 20 Candy. You’re wondering if purifying it is a good idea.

• Inputs:
  • Shadow Attack IV: 10
  • Shadow Defense IV: 10
  • Shadow HP IV: 10
  • Stardust Cost: 20,000
  • Candy Cost: 20
• Outputs (from calculator):
  • Purified Attack IV: MIN(10 + 2, 15) = 12
  • Purified Defense IV: MIN(10 + 2, 15) = 12
  • Purified HP IV: MIN(10 + 2, 15) = 12
  • Total Purified IV Sum: 12 + 12 + 12 = 36
  • Purified IV Percentage: (36 / 45) * 100% = 80%
  • Stardust Cost: 20,000
  • Candy Cost: 20

Interpretation: While purifying this Shadow Mewtwo would give you a respectable 80% IV Mewtwo, it would cost a significant amount of Stardust and Candy. More importantly, you would lose the 20% attack bonus that makes Shadow Mewtwo one of the strongest attackers in the game, even with lower IVs. In this case, most trainers would opt to keep it as a Shadow Pokémon, as its raw damage output often outweighs the IV boost from purification. The Pokémon Go Purify Calculator helps highlight this trade-off.

8. Copy Results: Click the “Copy Results” button to quickly save the calculated values to your clipboard for sharing or record-keeping.

How to Read Results and Decision-Making Guidance:

• Purified IVs: Look for high IVs, especially 15/15/15 (a “hundo”). If a Shadow Pokémon becomes a hundo after purification, it’s often a strong candidate for purification, especially if its Shadow form isn’t top-tier or if you need a cheaper-to-power-up perfect Pokémon.
• Overall Purified IV Percentage: This gives you a quick overview of the Pokémon’s perfection. A higher percentage means better overall stats.
• Stardust and Candy Costs: Compare these costs to your current resources. Is it worth the investment for the resulting IVs? Legendary Shadow Pokémon have very high costs, making purification a more significant decision.
• Shadow vs. Purified Utility: Always consider the Pokémon’s role. For raid attackers, the 20% Shadow attack bonus often outweighs higher IVs from purification. For PvP, it depends on the league and specific Pokémon; some benefit from the bulk of purified forms, while others thrive on Shadow damage. Our Pokémon Go Purify Calculator helps you see the IV change, but the strategic decision is yours.

Key Factors That Affect Pokémon Go Purify Results

Several factors influence whether purifying a Shadow Pokémon is a good decision. Understanding these can help you use the Pokémon Go Purify Calculator more effectively.

1. Current Shadow IVs: This is the most direct factor. A Shadow Pokémon with 13/13/13 IVs will become a perfect 15/15/15 after purification, which is a significant boost. A Shadow with 0/0/0 IVs will become 2/2/2, which is still a boost but less impactful.
2. Pokémon Species and Base Stats: Some Pokémon benefit more from IV boosts than others. A Pokémon with naturally high base stats might see less relative improvement from +2 IVs compared to a Pokémon with lower base stats. Also, the utility of the Pokémon in its Shadow vs. Purified form varies greatly by species (e.g., Shadow Machamp vs. Purified Snorlax).
3. Purification Costs (Stardust & Candy): These costs vary widely. Common Pokémon might cost 1,000 Stardust and 1 Candy, while Legendary Pokémon cost 20,000 Stardust and 20 Candy. High costs make purification a more serious resource investment, especially for a marginal IV gain.
4. Role in Battles (Raids, Gyms, PvP):
   • Raids/Gyms: Shadow Pokémon often outperform purified versions due to their 20% attack bonus, even with lower IVs. The extra damage output is usually preferred.
   • PvP: The decision is more nuanced. Some Pokémon prefer the bulk of purified forms (e.g., for Great League or Ultra League where IVs are optimized for specific CP caps), while others still benefit from the Shadow attack bonus.
5. Availability of Resources: Your current Stardust and Candy reserves play a big role. If you’re low on resources, purifying a costly Pokémon might not be the best immediate move, even if the IVs are good.
6. Collection Goals: For some trainers, collecting perfect IV Pokémon (hundos) is a primary goal. If a Shadow Pokémon can become a hundo after purification, it might be worth the cost for collection purposes, regardless of its battle utility.
7. Exclusive Moves: Purifying a Shadow Pokémon replaces “Frustration” with “Return.” While “Return” is a decent normal-type charged attack, some Pokémon have access to much better exclusive moves (e.g., Community Day moves). You need to consider if “Return” is a desirable move for that Pokémon or if you’ll need to use an Elite Charged TM later.

Frequently Asked Questions (FAQ) about the Pokémon Go Purify Calculator

Q: What is the main benefit of using a Pokémon Go Purify Calculator?

A: The main benefit is to quickly and accurately see the exact IVs your Shadow Pokémon will have after purification, along with the Stardust and Candy costs. This helps you decide if the purification is worth the investment and if the resulting Pokémon meets your strategic or collection goals.

Q: Does purifying a Pokémon always make it stronger?

A: Not necessarily. While purification increases IVs and reduces power-up costs, it removes the 20% attack bonus that Shadow Pokémon possess. For many offensive roles (like raid attackers), a Shadow Pokémon with lower IVs can still outperform a purified one with higher IVs due to this significant attack boost.

Q: Can a Shadow Pokémon become a 100% IV (hundo) after purification?

A: Yes! If a Shadow Pokémon has at least 13 Attack, 13 Defense, and 13 HP IVs, purifying it will boost each stat by 2, resulting in a perfect 15/15/15 IV spread. Our Pokémon Go Purify Calculator will show you if this is possible.

Q: What happens to the move “Frustration” when I purify a Shadow Pokémon?

A: When you purify a Shadow Pokémon, its charged attack “Frustration” is permanently replaced with “Return,” a normal-type charged attack. This is one of the key benefits, as “Frustration” is generally a very poor move.

Q: Are the purification costs the same for all Pokémon?

A: No, purification costs vary significantly by Pokémon species. Common Pokémon like Pidgey might cost 1,000 Stardust and 1 Candy, while Legendary Shadow Pokémon like Mewtwo will cost 20,000 Stardust and 20 Candy. Always check the in-game cost before purifying.

Q: Should I purify a Shadow Legendary Pokémon?

A: Generally, it’s recommended to keep high-tier Shadow Legendary Pokémon as Shadow, especially if they have good IVs, due to their immense power with the 20% attack bonus. Purifying them removes this bonus and costs a lot of resources. However, if you specifically need a perfect IV version for Mega Evolution or a niche PvP role, and you have resources to spare, it might be considered.

Q: How does the Pokémon Go Purify Calculator handle IVs above 13?

A: If a Shadow Pokémon has an IV of 14 or 15 in any stat, purifying it will still boost that stat by 2, but it will be capped at 15. For example, a 14 Attack IV becomes 15, and a 15 Attack IV also becomes 15.

Q: Can I use this calculator to decide which Pokémon to purify for the Purified Pokémon medal?

A: Yes, absolutely! If your goal is to earn the Purified Pokémon medal, you can use the calculator to find the cheapest Pokémon to purify (e.g., those costing 1,000 Stardust and 1 Candy) to quickly advance your medal progress without wasting valuable resources on more expensive Pokémon.
