What is a Pokemon Evolution Calculator?

A pokemon evolution calculator is a specialized tool used by Pokémon GO players to predict the Combat Power (CP) a Pokémon will have after it evolves. By inputting your Pokémon’s current species and CP, the calculator uses a species-specific multiplier to estimate the future CP. This is invaluable for strategic gameplay, helping you decide whether to invest precious candies and stardust into evolving a particular Pokémon. Knowing the potential outcome allows you to build stronger teams for raids, gym battles, and PvP leagues more efficiently.

Pokemon Evolution Formula and Explanation

The core of the pokemon evolution calculator lies in a simple but effective formula. The estimated CP of an evolved Pokémon is not random; it’s based on its current CP and a hidden value specific to its species known as the “CP Multiplier.”

The formula is:

Estimated Evolved CP = Current CP * CP Multiplier

Each Pokémon species has an average multiplier that dictates how much its CP will increase upon evolution. For instance, Pokémon like Magikarp have a very high multiplier, leading to a massive CP jump when it becomes Gyarados. Others, like Weedle, have a much smaller multiplier. This calculator uses these known averages to provide a reliable estimate.

Example Evolution Multipliers

This table shows the approximate CP multipliers for a few popular Pokémon.

Variable (Pokémon)	Meaning (Evolves To)	Unit (Avg. CP Multiplier)	Typical Range
Magikarp	Gyarados	~10.5x	10.0x – 11.0x
Eevee	Vaporeon, Jolteon, Flareon	~2.7x	2.5x – 2.9x
Pidgey	Pidgeotto	~1.9x	1.8x – 2.0x
Dratini	Dragonair	~2.0x	1.9x – 2.1x
Caterpie	Metapod	~1.05x	1.0x – 1.1x

Practical Examples

Example 1: Evolving a High-Potential Magikarp

You catch a Magikarp with a relatively high CP for its species. Is it worth the 400 candies to evolve?

• Inputs: Pokémon = Magikarp, Current CP = 150
• Calculation: 150 * 10.5 (approx. multiplier)
• Result: The pokemon evolution calculator estimates your new Gyarados will have a CP of around 1575. This is a massive increase, making it a great candidate for evolution.

Example 2: A Common Pidgey Evolution

You have a Pidgey and enough candy to evolve it. What can you expect?

• Inputs: Pokémon = Pidgey, Current CP = 300
• Calculation: 300 * 1.9
• Result: The calculator predicts the evolved Pidgeotto will have a CP of approximately 570. For one of many great {related_keywords}, see our guide.

Key Factors That Affect Evolution CP

While our pokemon evolution calculator provides a strong estimate, a few factors contribute to the final number:

• Current CP: This is the most direct factor. A higher starting CP will always result in a higher evolved CP.
• Pokémon Species: As shown in the table, the species determines the multiplication factor. This is the primary reason for the vast differences in CP gain.
• Individual Values (IVs): This is a hidden set of stats (Attack, Defense, Stamina) unique to each individual Pokémon. A Pokémon with higher IVs will have a slightly higher CP at the same level than one with lower IVs, and this difference carries through the evolution, sometimes causing slight variations from the average multiplier. Our IV calculator can help you understand this more.
• Pokémon Level: While not a direct input, the Pokémon’s level (which determines its max possible CP) is factored into its current CP. The evolution process preserves the Pokémon’s level.
• Game Updates: Niantic occasionally rebalances Pokémon stats, which can slightly alter CP multipliers. Our tool is updated to reflect these changes.
• Special Evolutions: Some Pokémon have multiple evolution paths (like Eevee). The calculator uses an average multiplier, but the exact result can depend on the specific evolution. For more on {related_keywords}, check out this resource.

Frequently Asked Questions (FAQ)

1. Is the estimated CP 100% accurate?

It’s very close! The calculation is based on average multipliers. The final CP can vary slightly due to a Pokémon’s hidden Individual Values (IVs), but this calculator will give you a highly reliable estimate for strategic planning.

2. Does player level affect the evolution multiplier?

No, your trainer level does not change the multiplier itself. However, as you level up, you will find Pokémon with a higher maximum possible CP, which in turn leads to higher CP evolutions.

3. Why isn’t my Pokémon in the list?

This calculator includes a selection of popular Pokémon to demonstrate the concept. We are continuously adding more species. Pokémon that don’t evolve (like Heracross) or are the final evolution are not included.

4. Should I power up my Pokémon before or after evolving?

It makes no difference to the final CP. The total cost in stardust and candy to reach a certain CP is the same regardless of the order. However, most players recommend evolving first to ensure the evolved Pokémon gets a good moveset before you invest stardust. For an in-depth analysis, read our power-up strategy guide.

5. What is Combat Power (CP)?

CP is a summary measurement of a Pokémon’s combat strength, calculated from its Attack, Defense, and Stamina stats, as well as its level.

6. Does the calculator account for weather boosts?

No. This calculator predicts the base evolved CP. A weather boost affects the CP of wild Pokémon you catch but does not alter the evolution calculation itself.

7. How are Eevee’s evolutions handled?

Eevee has multiple possible evolutions. The calculator uses an average multiplier for Vaporeon, Jolteon, and Flareon. The specific outcome will be close to the estimate provided.
