Understanding Pokemon GO CP
In Pokemon GO, Combat Power (CP) is the primary numerical value that represents a Pokemon's overall strength in battle. While the game displays a single CP number, this value is actually the result of a complex calculation that factors in a Pokemon's base stats, its current level, and its Individual Values (IVs).
Whether you're preparing for Go Battle League, building a team for Raids, or simply trying to understand how strong your caught Pokemon truly are, knowing how CP is calculated is crucial. Our Pokemon GO CP Calculator allows you to see the exact math behind your Pokemon's power, helping you make informed decisions about which Pokemon are worth investing Stardust and Candy into.
The Hidden Stats Behind CP
Every species of Pokemon in Pokemon GO has three base stats: Attack, Defense, and Stamina (HP). These base stats are determined by the Pokemon's species and are translated from the main series games. For example, a Mewtwo will always have incredibly high base attack stats compared to a Pidgey. However, within the same species, Pokemon vary in strength due to their Individual Values.
Individual Values, or IVs, are hidden bonus points added to a Pokemon's base stats. Each stat (Attack, Defense, and Stamina) can have an IV ranging from 0 to 15. A "perfect" or "100% IV" Pokemon has 15 in all three stats. These IVs ensure that no two Pokemon of the same species and level will necessarily have the exact same CP.
The CP Multiplier and Pokemon Level
A Pokemon's level is another critical factor in determining its CP. In Pokemon GO, levels aren't explicitly shown as numbers; instead, they are represented by the arc behind the Pokemon. Levels range from 1 to 50 (or 51 with Best Buddy boost), with half-level increments. Each level corresponds to a specific "CP Multiplier" (CPM).
The CPM is a decimal value that scales up as the Pokemon's level increases. When a Pokemon levels up, its stats are multiplied by this larger CPM, resulting in higher effective stats and, consequently, a higher CP. The increase in CPM slows down significantly after level 30, and even more so after level 40, which is why powering up higher-level Pokemon requires more resources for smaller CP gains.
The Official CP Formula
The calculation that determines a Pokemon's CP might seem complicated, but it follows a specific, consistent formula. By taking the total stats (Base Stat + IV) and the CP Multiplier, the game uses the following equation to generate the final Combat Power number:
Let's break down how this formula weights the different stats. Notice that the Attack stat is multiplied normally, but Defense and Stamina are square-rooted (raised to the power of 0.5). This means that the Attack stat has a disproportionately large impact on a Pokemon's final CP compared to Defense and Stamina.
This mathematical weighting is why Pokemon with high base Attack stats (like Alakazam or Gengar) often have higher maximum CP than bulkier Pokemon with similar total stats (like Blissey or Umbreon). It is also why many competitive players in CP-capped leagues (like the Great League or Ultra League) prefer Pokemon with low Attack IVs but high Defense and Stamina IVs. Because Attack inflates CP so rapidly, minimizing the Attack IV allows the Pokemon to reach a higher overall level and gain more raw bulk before hitting the 1500 or 2500 CP limit.
Optimizing for PVP vs. PVE
Understanding how CP is calculated allows you to optimize your Pokemon for different aspects of the game. For Player vs. Environment (PVE) activities like Raids and Gym battles, there is no CP cap. Therefore, you generally want the highest CP possible, which means aiming for 100% IVs (15/15/15) and powering the Pokemon up to the highest level you can afford.
However, for Player vs. Player (PVP) in the Go Battle League, strategy changes based on the league. In the Master League, where there is no CP limit, 100% IVs are still the goal. But in the Great League (1500 CP limit) and Ultra League (2500 CP limit), the goal is to maximize stat product—the raw effectiveness of the Pokemon—while staying under the CP cap.
Because the CP formula heavily penalizes the Attack stat by inflating CP faster, a Pokemon with an IV spread like 0/15/15 can often reach a higher level (and thus gain more total Defense and Stamina) before hitting the 1500 CP cap than a 15/15/15 Pokemon of the same species. Our calculator helps you visualize these mathematical nuances so you can build the strongest possible teams.
Frequently Asked Questions
What is CP in Pokemon GO?
Combat Power (CP) is a numerical representation of a Pokemon's overall fighting ability. It is calculated using a hidden formula that combines the Pokemon's base stats (Attack, Defense, and Stamina), its Individual Values (IVs), and its current Level (which determines the CP Multiplier).
Why do some Pokemon have higher CP than others at the same level?
There are two main reasons. First, different species have different base stats; a Dragonite naturally has higher base stats than a Caterpie. Second, even between two Pokemon of the same species at the same level, differences in their Individual Values (IVs) will cause slight variations in their final CP.
Why is a low Attack IV better for Great League PVP?
In the official CP formula, the Attack stat has a much larger impact on the final CP number than Defense or Stamina. Because the Great League has a strict 1500 CP limit, minimizing the Attack IV allows the Pokemon to reach a higher level and gain significantly more Defense and Stamina before hitting the cap, resulting in a bulkier, more effective fighter.
What is the maximum level for a Pokemon in Pokemon GO?
A Pokemon can be powered up to level 50 using Candy XL and Stardust. However, if a Pokemon reaches "Best Buddy" status, it receives a temporary one-level boost when assigned as your active buddy, effectively raising its maximum level to 51 and increasing its CP accordingly.
Can I calculate the CP of an unevolved Pokemon after it evolves?
Yes, though it requires knowing the base stats of the evolved form. The Pokemon's Level and IVs remain exactly the same when it evolves. Our CP calculator allows you to input the base stats of the evolved species while keeping your current IVs and Level to see its future CP.
