Pokémon GO CP & IV Calculator
The Pokémon GO CP & IV Calculator estimates Combat Power based on base stats, individual values, and Pokémon level. This tool helps trainers understand how different IV combinations affect CP at various levels. Whether you're powering up a favorite Pokémon, comparing raid catches, or planning for battle leagues, this calculator provides instant CP estimates.
This calculator is for informational purposes only. CP values are estimates based on game formulas and may not account for in-game modifiers or special events.
Use this free online Pokémon GO CP & IV Calculator to calculate your Combat Power. Simply enter your base stats, IV values, and Pokémon level to instantly get results in CP, IV percentage, and effective HP. Results show estimated battle strength for Pokémon GO gameplay planning.
How Combat Power Is Calculated
Combat Power (CP) represents a Pokémon's overall strength in battle. The game calculates CP using three main factors: the species base stats, individual values (IVs), and a level multiplier called CPM. Base stats are fixed numbers for each Pokémon species. IVs are bonus points from 0 to 15 that make each Pokémon unique. The CPM value increases as the Pokémon gains levels through powering up.
CP = floor(((BaseAtk + AtkIV) × sqrt(BaseDef + DefIV) × sqrt(BaseSta + StaIV) × CPM²) ÷ 10)
Where:
- BaseAtk = species base attack stat
- AtkIV = individual attack value (0-15)
- BaseDef = species base defense stat
- DefIV = individual defense value (0-15)
- BaseSta = species base stamina stat
- StaIV = individual stamina value (0-15)
- CPM = combat power multiplier for the Pokémon's level
The formula multiplies all stats together with the level multiplier, then divides by 10 and rounds down. This matches how the game displays CP values. Attack stats have more impact on CP than defense or stamina because they are not square-rooted.
What Your Pokémon GO CP Result Means
Your CP result shows the estimated Combat Power for a Pokémon with the stats you entered. Higher CP generally means the Pokémon is stronger in battles, but CP does not tell the whole story. A Pokémon with high CP but poor IVs may still perform worse than one with lower CP but better stats for its intended use.
IV Percentage shows how close your Pokémon is to having perfect stats. A 100% IV Pokémon has 15 points in all three categories (Attack, Defense, Stamina). Most wild Pokémon have IVs between 50% and 80%. Raid bosses and research rewards typically have higher IV floors, often starting at 66% or higher.
| IV Rating | IV Percentage | Description |
|---|---|---|
| Perfect | 100% (45/45) | Maximum possible IVs in all stats |
| Excellent | 82-99% | Great for raids and gym battles |
| Good | 67-81% | Solid for general gameplay |
| Average | 51-66% | Common for wild catches |
| Below Average | 0-50% | May not be worth powering up |
Effective HP shows how much damage your Pokémon can take in battle. This value depends on stamina stats and level, and helps compare bulkiness between different Pokémon.
Accuracy, Limitations & Common Mistakes of the Pokémon GO CP Calculator
How Accurate Is the Pokémon GO CP Calculator?
This calculator uses the exact formula that Pokémon GO uses to compute CP values. The results match in-game CP displays for standard Pokémon. The CPM values are taken from official game data and include all levels from 1 to 51. Small differences may appear due to rounding in the game's display, but calculated values should match what you see in your Pokémon storage.
Limitations of the Pokémon GO CP Calculator
This calculator does not account for Shadow Pokémon bonuses, which add a 20% attack boost and reduce defense. Mega Evolved Pokémon use different base stats that may not be reflected here. Weather boosts do not affect CP calculation but do affect IV floors for wild catches. The calculator also does not consider move sets, type effectiveness, or battle mechanics that affect actual combat performance beyond raw CP.
Common Mistakes to Avoid
- Entering IV values above 15: IVs in Pokémon GO are always between 0 and 15. Values outside this range are invalid.
- Confusing base stats with CP: Base stats are hidden numbers specific to each species. Check online resources like the official Pokémon GO website or community databases for accurate base stat values.
- Ignoring level caps: Not all trainers can power up to level 51. Your trainer level determines the maximum level you can achieve for your Pokémon.
- Overvaluing CP for PvP: In Great League and Ultra League, lower CP Pokémon with better stat distribution often perform better than high CP options.
Frequently Asked Questions
Who is this Pokémon GO CP Calculator for?
This calculator is designed for Pokémon GO players who want to understand how CP is calculated and estimate values for different IV combinations. It is useful for trainers planning power-ups, comparing raid catches, or deciding which Pokémon to invest resources in. Both casual players and dedicated trainers can benefit from understanding CP mechanics.
How often should I use this calculator?
Use this calculator whenever you catch a new Pokémon and want to check its potential CP at higher levels. It is also helpful when deciding between multiple Pokémon of the same species, or when planning for raid battles and PvP leagues where CP limits apply.
Where can I find base stats for my Pokémon?
Base stats are not shown directly in the game. You can find them on community websites like Pokébattler, GamePress, or the official Pokémon GO support pages. Each species has fixed base stats for attack, defense, and stamina that do not change between individual Pokémon.
Can I use this calculator for Shadow and Mega Pokémon?
This calculator shows base CP values without Shadow bonuses or Mega stat changes. Shadow Pokémon have a 1.2x attack multiplier and 0.833x defense multiplier that affect battle performance but not the displayed CP. Mega Pokémon have different base stats that may need to be entered separately for accurate calculations.
Is the Pokémon GO CP Calculator free to use?
Yes, this calculator is completely free with no sign-up required. It works on any device with a web browser and provides instant results.
