How the Catch Rate is Calculated
In Pokémon GO, the probability of catching a Pokémon is determined by a complex formula that involves the species' Base Catch Rate (BCR), the Pokémon's level, and various multipliers from your items and throwing technique.
The core formula used in this calculator is:
Probability = 1 – (1 – BCR / (2 × CPM))^Multiplier
Where CPM (CP Multiplier) is a value determined by the Pokémon's level, and Multiplier is the product of all your bonuses (Ball, Berry, Throw, Curve, and Medals).
Key Multipliers Explained
| Factor | Multiplier Value |
|---|---|
| Curveball | 1.7x |
| Ultra Ball | 2.0x |
| Great Ball | 1.5x |
| Golden Razz Berry | 2.5x |
| Excellent Throw | Approx. 1.7x – 2.0x |
| Platinum Medal | 1.4x |
Tips to Increase Your Catch Rate
- Always use Curveballs: A curveball provides a massive 1.7x multiplier, which is better than using a Great Ball over a Poké Ball.
- Target the Circle: The smaller the target circle when you hit it, the higher the "Throw Accuracy" multiplier. An Excellent throw can double your chances compared to a standard hit.
- Stack Bonuses: Multipliers are multiplicative, not additive. Using a Golden Razz Berry, an Ultra Ball, and a Curveball together exponentially increases your success rate.
- Level Matters: Higher-level Pokémon have lower CPM values, making them significantly harder to catch. A Level 35 Pokémon in the wild will be much more stubborn than a Level 5 Pokémon.
Standard Base Catch Rates (BCR)
If you aren't sure what BCR to enter, here are some common values:
- Legendary Pokémon: Usually 2% or 3%
- Common Spawns (Pidgey, Rattata): 40% to 50%
- Starter Pokémon (Bulbasaur, etc.): 20%
- Rare Evolutions (Dragonite, Tyranitar): 4% to 5%
