Pokémon CP After Evolution: Predicting Your Team's New Power
You've spent weeks collecting candies and catching dozens of the same species. You finally have a high IV candidate. But before you click that "Evolve" button, a critical question remains: What will the CP be after it evolves? The Pokémon CP After Evolution Calculator is designed to remove the guesswork, predicting the final power level of your Pokémon based on its current stats and species potential.
Why Does CP Change So Much After Evolution?
When you evolve a Pokémon in Pokémon GO, two things happen: One stays the same, and one changes drastically. The Level (and its corresponding CP Multiplier) remains constant. However, the Base Stats (Attack, Defense, and Stamina) are replaced by those of the evolved species. Since the base stats of a Charizard are much higher than those of a Charmander, the resulting CP is much higher, even though the level is identical.
The Mathematics of Evolution Prediction
There are two ways to predict evolved CP: the "Quick Multiplier" method and the "Exact Base Stat" method.
1. The Evolution Multiplier (Estimation)
For most players, a multiplier is enough. Every species has an average multiplier. For example, a Machop typically evolves into a Machamp with a multiplier of roughly 2.6x. If you have an 800 CP Machop, you can expect a ~2080 CP Machamp. However, multipliers aren't perfect because they are affected by your individual IVs.
2. The Base Stat Formula (Precision)
The gold standard for prediction uses the full CP formula with the new species' base stats:
Evolved CP = Floor( (New-Base-Atk + IV-Atk) * sqrt(New-Base-Def + IV-Def) * sqrt(New-Base-Sta + IV-Sta) * CPMultiplier^2 / 10 )
PvP Thresholds: The Most Critical Use-Case
If you are a competitive player in the GO Battle League, evolution prediction is your most important tool. The "Great League" has a strict 1500 CP cap, and the "Ultra League" has a 2500 CP cap. If your evolved Pokémon hits 1501 CP, it is permanently banned from the Great League.
- Perfect PvP IVs: Often involve a 0/15/15 spread. These Pokémon evolve to hit the maximum possible bulk while staying under 1500 CP.
- The Checkpoint: Always use the calculator if your predicted CP is between 1480 and 1520 or 2480 and 2520.
Unique Evolution Multipliers: The Outliers
While most Pokémon have a multiplier between 1.5x and 2.2x, some species are outliers:
- Magikarp to Gyarados: With a multiplier of ~15x to ~18x, this is the largest jump in the game. A tiny 10 CP Magikarp can become a ~150 CP Gyarados!
- Feebas to Milotic: Another massive jump, often exceeding 10x.
- Weedle to Kakuna: This is one of the few cases where CP can actually decrease. Because Kakuna's Attack is lower than Weedle's (relative to their total stats), the CP (weighted toward Attack) often drops by a few points.
The Social Cost: Trade Evolutions
In modern Pokémon GO, several species (like Machoke, Haunter, Graveler, and Kadabra) have a "Trade Evolution" feature. If you receive one of these in a trade, it costs zero candies to evolve it to its final stage. This is a huge advantage for building high-CP Raid teams quickly, as you don't need to farm 100 candies. However, remember that trading randomizes IVs, so you must recalculate the evolved CP after the trade is complete.
Practical Strategy for New Trainers
Don't just evolve because you have the candies. If you are catching a high-level Pokémon (Level 30+) in the wild, its "evolved CP" will already be battle-ready for Raids without any Stardust investment. For example, a wild Level 35 Ryhorn evolved into Rhyperior will naturally sit at ~3300 CP—an instant powerhouse. Save your Stardust for your high-IV, specialized PvP Pokémon instead.
Conclusion: Evolve with Confidence
The Pokémon CP After Evolution Calculator is the ultimate guardrail for your resources. By simulating the transition before you commit your hard-earned candies, you ensures your team hits exactly the marks you want—whether that's a 1499 CP Skarmory for GL or a 4000 CP Slaking for gym defense. Don't leave your evolution to chance; calculate it first.
