Spent 400 Candies evolving your Magikarp only to get a disappointing Gyarados CP? Never again. Our Pokémon Go Evolution CalculatorPokémon Go, the exact CP range your Pokemon will reach after evolutPokémonefore you commit a single Candy or Stardust. Just pick your Pokémon, enter its current CP, and hit Calculate. Simple, instant, and accurate.
This evolve calculator uses base stats and CP multipliers from the official Pokemon GO game master file to estimate your evolved Pokemon’s strength. Select your species, enter the current Combat Power shown in your game, and click Calculate. You will see three values instantly: the minimum, average, and maximum CP your evolved form can reach. No account, no download, no waiting.
Using this tool takes under 30 seconds. No account needed, no download required, open and calculate. Select your Pokémon. Type the name or choose from the dropdown. EverPokémonon in the game is listed, including all regional variants, Mega Evolutions, and special forms. Enter your current CP. Open yourPokémon GoO app, tap on the Pokémon you want to evolve, and note the CP number shown at the top of the screen. Hit the Calculate button. Instantly see the predicted CP range for every available evolution stage. Review your results. If the numbers look strong, evolve with confidence. If they seem low, save your Candy and wait for a better candidate.
CP stands for Combat Power. It is the single number that determines how strong yourPokémonn performs in Gym battles, Raid battles, and PvP (Player vs. Player) leagues. The higher the CP, the stronger your Pokémon hits and the longer it survives in battle.
CP is calculated from three underlying stats combined with a level-based multiplier:
Attack: How much damage your Pokémon deals
Defense: How well your Pokémon resists incoming damage
Stamina (HP): How much damage your Pokémon can absorb before fainting
When a Pokémon evolves, its base stats change to the evolved form’s values, and CP can jump dramatically. A Magikarp evolving into Gyarados multiplies its CP by approximately 10 times. A Pidgey evolving into Pidgeot roughly doubles its CP. The exact multiplier differs for every species, which is exactly why this calculator exists,s because guessing is never good enough when Candy is involved.
Candy and Stardust take real effort to farm, so spending them on a weak evolution hurts. A combat power calculator protects that investment in four ways.
Save Candy and Stardust. Not all evolutions are equally rewarding. Some species receive only a 50 percent CP boost on evolving, while others triple or even quadruple. The calculator shows the payoff before you commit, so you invest only in evolutions that are worth it.
Build stronger battle teams. When you have multiple copies of the same Pokemon, this evolution calculator lets you compare each one and identify the strongest post-evolution result. Your team ends up with the best possible version.
Avoid PvP league mistakes. In Great League with its 1500 CP cap and Ultra League with its 2500 CP cap, going even one point over the limit makes your Pokemon ineligible. The maximum projected CP from this tool keeps you safely under the cap, so you never accidentally disqualify a Pokemon you spent weeks building.
Plan raid performance. Before an important Raid day, use the Pokemon GO evolution calculator to confirm your evolved Pokemon will be strong enough to contribute meaningfully, not just barely eligible.
This is one of the most searched questions in all of Pokémon Go and the answer is almost always the same: evolve first, then power up.
Here is why: When you power up a Pokémon, you spend Stardust to raise its level, which increases CP based on its current base stats. After evolution, the base stats change to the evolved form’s much higher values. That means every power-up you do after evolving gives you dramatically more CP per Stardust spent.
The one exception: if you are targeting a PvP league CP cap. Use the evolution calculator first to confirm your evolved Pokemon will not exceed 1,500 CP (Great League) or 2,500 CP (Ultra League) before you start powering up.
Our evolution calculator covers the complete Pokémon Go Pokedex, updated with every new game master file release. SupportedPokémonn include:
• All standard evolutions across every generation (Kanto through Paldea)
• Branching evolutions Eevee’s 8 Eeveelutions, Tyrogue’s 3 evolution paths, and all other split evolutions
• Mega Evolutions CP predictions for Raid and Master League planning
• Shadow and Purified Pokemon same mechanics, with the Purified form starting at Level 25
• Regional variants and special forms, including Alolan, Galarian, Hisuian, and Paldean forms
• Legendary and MythicalPokémonn full CP calculations for raid-caught and research-reward species
Not sure which Eeveelution to pick? The calculator shows you all 8 post-evolution CP values simultaneously so you can pick the one that best fits your team and your available resources.
Answers to the most common questions trainers have about the Pokemon GO Evolution Calculator.
Yes. The tool uses the same CP formula that Pokemon GO uses internally, based on each species’ base Attack, Defense, and Stamina stats multiplied by a level-based CP Multiplier. Results are highly accurate with a min to max range shown to account for hidden IV variation.
No. Individual Values are permanent and carry through evolution unchanged. Only the base stats change to the evolved form’s values. A 100 percent IV Pokemon before evolving remains 100 percent IV after.
No. Shiny Pokemon follow the exact same CP formula as their regular counterparts. The calculator works identically for both because Shiny status only affects appearance, not stats.
No. Weather boosts are a temporary in-game modifier and are not part of the evolution CP formula. The calculator gives you the base post-evolution CP which is what your Pokemon retains permanently.
Shadow Pokemon follow the same evolution mechanics as regular Pokemon. Purified Pokemon that were below Level 25 when caught are boosted to Level 25, so their post-evolution CP will typically be higher than a Shadow counterpart caught at the same base CP.
Each of Eevee’s eight evolutions has completely different base stats. Vaporeon is built for high HP, Jolteon for Attack, and Umbreon for Defense. The calculator shows all eight CP results simultaneously.
The Magikarp to Gyarados evolution costs 400 Candies, one of the highest candy costs in the entire game. The calculator confirms the CP payoff before you spend it.
