Every wild Pokémon and Raid Boss encounter in Pokémon GO is governed by a mathematical capture probability formula combining Base Catch Rate (BCR), Combat Power Multiplier (CPM), ball types, berries, medal tiers, and throw accuracy.
The Core Catch Rate Formula
The probability of catching a Pokémon on a single throw is calculated as:Catch Rate = 1 - (1 - BCR / (2 * CPM)) ^ Multiplier
Top Catch Rate Multipliers
- Curveball: 1.7x flat multiplier on every throw.
- Golden Razz Berry: 2.5x multiplier (crucial for Legendary Raids).
- Platinum Type Medals: 1.4x multiplier.
- Excellent Throw: 1.85x multiplier.
