Pokemon Evolution Calculator

What is a Pokémon Evolution Calculator?

A pokemon evolution calculator is a specialized tool used by players of games like Pokémon GO to predict the future Combat Power (CP) of a Pokémon after it evolves. Each Pokémon species has a hidden “evolution multiplier.” This tool uses that multiplier, combined with your Pokémon’s current CP, to provide a reliable estimate of its strength post-evolution. This allows you to make strategic decisions about which Pokémon to invest your valuable Stardust and Candy in.

Using this calculator prevents surprises and helps you focus on evolving Pokémon that will become powerful contenders in raids and battles. Instead of evolving a low-potential Pokémon, you can wait for a better one and use this tool to see if it’s worth the resources.

Pokémon Evolution Formula and Explanation

The core logic of the pokemon evolution calculator is straightforward. The estimated CP after evolution is calculated using the following formula:

Evolved CP = Current CP × Evolution Multiplier

Because the evolution multiplier is not a single fixed number but a range, the calculator provides a minimum and maximum expected CP. This gives you a likely CP window your Pokémon will fall into.

Evolution Multiplier Examples

This table shows average evolution multipliers for a few popular Pokémon.
Variable (Pokémon)	Meaning	Unit (Multiplier)	Typical Range
Magikarp	Multiplier for evolving into Gyarados	Unitless	10.0 – 11.8
Pidgey	Multiplier for evolving into Pidgeotto	Unitless	1.7 – 1.9
Eevee (Random)	Average multiplier for Vaporeon, Jolteon, Flareon	Unitless	2.0 – 2.9
Dratini	Multiplier for evolving into Dragonair	Unitless	2.0 – 2.3
Larvitar	Multiplier for evolving into Pupitar	Unitless	1.6 – 1.8

Practical Examples

Let’s see the pokemon evolution calculator in action with two common scenarios.

Example 1: Evolving a High-CP Magikarp

Inputs: Pokémon = Magikarp, Current CP = 150
Units: CP is a unitless game value. The multiplier for Magikarp is ~10.9.
Results:
- Average Evolved CP: ~1635
- CP Range: Approximately 1500 – 1770 CP
Interpretation: This shows that a strong Magikarp can become a very powerful Gyarados, making it a great candidate for evolution. For more details on resource management, see our stardust farming guide.

Example 2: Deciding Between Two Pidgeys

Inputs: Pidgey #1 (CP 200), Pidgey #2 (CP 350)
Units: The Pidgey-to-Pidgeotto multiplier is ~1.8.
Results:
- Pidgey #1 Evolved CP: ~360
- Pidgey #2 Evolved CP: ~630
Interpretation: By plugging both into the pokemon evolution calculator, it’s clear that evolving the 350 CP Pidgey will yield a much stronger Pidgeotto. This is a simple but effective way to ensure you’re getting the most out of your candy.

How to Use This Pokémon Evolution Calculator

Follow these simple steps to determine your Pokémon’s potential:

Select the Pokémon: Choose your Pokémon’s species from the dropdown list.
Enter Current CP: Input the current Combat Power of the Pokémon you want to evolve.
Review the Results: The calculator will instantly display the estimated CP range. The primary result is the average expected CP, with minimum and maximum values provided for context.
Analyze the Chart: The bar chart provides a quick visual aid to compare the CP before and after the potential evolution.

Key Factors That Affect Evolution CP

While the formula is simple, several factors influence the final outcome and its strategic value.

Base Pokémon CP: This is the single most important factor. A higher starting CP directly leads to a higher evolved CP.
Species Multiplier: Some Pokémon, like Magikarp, have enormous multipliers, leading to huge CP gains. Others have very small multipliers.
IVs (Individual Values): While not directly used in this calculator, a Pokémon’s hidden Attack, Defense, and Stamina stats (IVs) determine its maximum possible CP. A high-IV Pokémon will have a higher CP cap. Check out our guide to IVs to learn more.
Two-Stage Evolutions: For Pokémon with three stages (e.g., Dratini -> Dragonair -> Dragonite), you must calculate each step separately. Our calculator focuses on a single evolution step.
Community Day Moves: Evolving during certain events can grant a special move, which doesn’t affect CP but significantly impacts battle performance. Knowing the event calendar is key.
Resource Cost: Consider the candy and stardust required. Evolving a Magikarp costs 400 candy, a significant investment that this calculator can help justify.

Frequently Asked Questions (FAQ)

1. How accurate is this pokemon evolution calculator?

It’s very accurate. The predictions are based on established multipliers discovered by the community. The result is a range because the exact multiplier has a slight variance, but your evolved Pokémon will fall within the provided window.

2. Do IVs affect the evolution multiplier?

No, the multiplier is constant for a species. However, a Pokémon with higher IVs will have a higher starting CP at the same level, which in turn leads to a higher evolved CP.

3. Why isn’t every Pokémon in the list?

This calculator includes a selection of popular Pokémon to demonstrate its function. The core principles and multipliers are similar for all other species.

4. Does this work for Eevee?

Yes, but it’s more complex. For a random evolution, the calculator uses an average multiplier. If you use a naming trick or a special lure to guarantee a specific Eeveelution, you should consult a specialized Eevee evolution guide for the precise multiplier.

5. What does ‘unitless’ mean for the multiplier?

It means the multiplier is a direct scaling factor. You simply multiply it by the CP. It doesn’t represent a physical unit like kilograms or meters.

6. Can I use this calculator for power-ups?

No, this tool is specifically for evolution. Powering up a Pokémon increases its CP in small increments based on its level, stardust cost, and IVs. You’ll need a different tool, like a power-up cost calculator, for that.

7. Should I purify a Shadow Pokémon before evolving?

Purifying a Shadow Pokémon increases its IVs and reduces power-up costs, but it loses its shadow damage bonus. Calculating the evolution CP of both its Shadow and Purified forms can help you decide. Shadow Pokémon have a lower starting CP but a 20% attack bonus in battle.

8. What if my result seems wrong?

Double-check that you’ve entered the correct Current CP and selected the right Pokémon. A simple typo is the most common source of error.
