How Pokemon Go CP Is Calculated

Combat Power (CP) in Pokemon Go is a numerical value that indicates how strong a Pokemon is in battle. CP is determined by three base stats (Attack, Defense, Stamina) that vary by species, three Individual Values (IVs) that make each Pokemon unique, and the Pokemon's level. Higher CP generally means better performance in gyms and raids.

Understanding the CP Formula

The CP formula is: CP = (Attack × √Defense × √Stamina × CPM²) / 10, where Attack, Defense, and Stamina include both base stats and IVs. The CP Multiplier (CPM) is a value that increases with the Pokemon's level, ranging from approximately 0.094 at level 1 to 0.79 at level 50.

IVs and Why They Matter

Individual Values (IVs) are randomly assigned when you catch a Pokemon. Each IV ranges from 0 to 15. A perfect Pokemon has 15/15/15 IVs. The IV percentage tells you how close your Pokemon is to perfection: a 100% Pokemon has 45 total IV points. IVs become more important at higher levels where the CP difference between a 0% and 100% IV Pokemon can be 10-15%.

Level Cap and XL Candy

Pokemon can be powered up to your Trainer Level + 10, capped at level 50. Powering up beyond level 40 requires XL Candy, which is earned by catching Pokemon of the same species, trading, walking your buddy, and converting regular Candy. Each power-up costs more stardust and candy as the level increases.

Frequently Asked Questions

How is Pokemon Go CP calculated?
Pokemon Go Combat Power (CP) is calculated using the formula: CP = (Base Attack + IV Attack) × √(Base Defense + IV Defense) × √(Base Stamina + IV Stamina) × CPM² / 10. The CP Multiplier (CPM) depends on the Pokemon's level. Higher level Pokemon have higher CPM values. IVs (Individual Values) range from 0-15 for each stat.
What are IVs in Pokemon Go?
IVs (Individual Values) are hidden stats that make each Pokemon unique. Each Pokemon has IVs for Attack, Defense, and Stamina, ranging from 0 to 15. A 100% IV Pokemon has 15/15/15 stats. IVs are determined when you catch or hatch the Pokemon and cannot be changed. Higher IVs mean higher CP potential.
What CP can my Pokemon reach when powered up?
The maximum CP depends on your trainer level and the Pokemon's species. At Trainer Level 40+, Pokemon can reach level 50 with XL Candy. A perfect (100% IV) Mewtwo can reach 4,764 CP at level 50, while a perfect Dragonite reaches 4,292 CP. Weather boost during catch gives Pokemon level 25-35.
What is a good IV percentage in Pokemon Go?
For raids and PvP, aim for: PvE (raids/gyms) — 90%+ IV (40/45 or higher). Great League PvP — often prioritize low Attack with high Defense/Stamina for CP optimization. Ultra League PvP — 90%+ IV or PvP IV spreads. Master League PvP — 100% IV (15/15/15) is ideal.
