Catch rate (GO)

Jump to: navigation, search

The calculation of catch rate is among the several mechanics that differ in Pokémon GO compared to the core series. Every species of Pokémon is assigned a base capture rate, a raw percentage that determines how difficult that species is to capture. This base rate is then modified by several factors, such as the wild Pokémon's Power Up level and how skillfully the player threw the Poké Ball, to determine the final catch rate.

For certain encounters, the encountered Pokémon is guaranteed capture on the first ball that hits, bypassing the catch rate calculation. These encounters include:


Upon a thrown Poké Ball successfully hitting a wild Pokémon, the game will calculate P, the probability of a successful capture.[1]

  • baseCaptureRate is the base capture rate of the wild Pokémon's species.
  • CPM is the CP multiplier corresponding to the wild Pokémon's Power Up level.
    • For standard wild encounters, a Pokémon's level ranges from 1 to 30 or 5 to 35 if weather boosted, with a CPM ranging from 0.094 to 0.7317 or 0.29024988 to 0.76156384, respectively.
    • For Raid Battles, a Pokémon's level is 20 or 25 if weather boosted, with a CPM of 0.5974 or 0.667934, respectively.
    • For research task encounters, a Pokémon's level is always 15, with a CPM of 0.51739395.
    • For Team GO Rocket encounters, a Pokémon's level is 8 or 13 if weather boosted, with a CPM of 0.37523559 or 0.48168495, respectively.
    • For GO Battle League reward encounters, a Pokémon's level is always 20, with a CPM of 0.5974.

  • Ball is
  • Berry is
  • Throw is 2 - r if the Ball hits within the target ring, and 1 otherwise
    • where r = (target ring size) / (maximum ring size), hence 0 < r ≤ 1
    • for a Nice Throw, 1 ≤ Throw < 1.3
    • for a Great Throw, 1.3 ≤ Throw < 1.7
    • for an Excellent Throw, 1.7 ≤ Throw < 2
  • Curveball is 1.7 if the Ball is spun before being thrown, and 1 otherwise
  • Encounter is 2 if the Pokémon is encountered for completing Field, Special or Timed Research tasks, and 1 otherwise
  • Medal is based on the player's type-specific Medals pertaining to the wild Pokémon's type and is
    • 1 if No Medal Pokémon GO.png none
    • 1.1 if Bronze Medal Pokémon GO.png bronze
    • 1.2 if Silver Medal Pokémon GO.png silver
    • 1.3 if Gold Medal Pokémon GO.png gold
    • 1.4 if 20px platinum
    • if the wild Pokémon has two types, Medal will be the average of the above for each type

When capturing Pokémon using a peripheral device, such as the Pokémon GO Plus or Poké Ball Plus, a regular Poké Ball will always be used with no bonus multipliers applied, except from type medals if applicable.

Target ring colors

The color of the target ring allows players to gauge the probability of a successful capture, factoring in all bonuses for multiplier except for Throw and Curveball. Switching Poké Balls or feeding Berries may change the color of the ring. The more green the ring, the higher the catch rate; the more red it is, the lower the catch rate.

The target ring of Shadow Pokémon are always colored to indicate a 5% base capture rate. However, it's been empirically observed that the true base capture rate is no different from the species' standard base capture rate.

Critical capture

Reason: Chance of critical capture?.

A critical capture is a rare phenomenon that was first observed in Pokémon GO in February 2017, alongside the release of Generation II Pokémon. Occasionally, a thrown Poké Ball will bypass catch rate calculations and guarantee a capture. Instead of shaking three times, a throw Poké Ball will only shake once, and the Pokémon will be confirmed caught. No additional bonuses are awarded for critical captures, but XP bonuses such as from Great or Curveball throws are still included.


Poké Balls and Berries

Consider a wild Pikachu with 343 CP, with an estimated Power Up level of 14. Pikachu has a base capture rate of 20% and a CP multiplier of 0.49985844 at level 14. Without any bonus multipliers, the catch rate will be 20% / (0.49985844×2) = 20.01%.

The following table shows what this Pikachu's catch rate would be if bonuses for Poké Balls and Berries were applied, assuming no bonuses from throws or medals.

Poké Ball Great Ball Ultra Ball
GO Pinap Berry.png 20.01% 28.45% 36.01%
GO Razz Berry.png 28.45% 39.48% 48.81%
Silver Pinap Berry 31.58% 43.40% 53.18%
Golden Razz Berry 42.77% 56.70% 67.24%
Throw technique

Consider a wild Tauros of 1252 CP, with an estimated Power Up level of 18. This means it will have a base capture rate of 30% and a CP multiplier of 0.56675452. Without any additional bonuses, the capture rate will be 30% / (2 × 0.56675452) = 26.47%.

The following table shows how the capture rate will be affected by throwing techniques, assuming no additional bonuses and only regular Poké Balls are used; throw bonus multipliers will be averaged between the highest and lowest possible values.

None Curveball
26.47% 40.70%
29.78% 45.17%
36.94% 54.34%
43.38% 61.97%

Let's now consider a wild Abra that has 670 CP, estimated to be Power Up level 20. Given that Abra has a base capture rate of 50% and its CP multiplier is 0.59740001, the catch rate without bonuses will be 50% / (2 × 0.59740001) = 41.85%.

The following table shows the effect on catch rate via medals for each Poké Ball type, assuming no other bonus multipliers.

Poké Ball Great Ball Ultra Ball
None 41.85% 55.65% 66.18%
Bronze type medal 44.92% 59.12% 69.66%
Silver type medal 47.82% 62.31% 72.78%
Gold type medal 50.58% 65.25% 75.57%
Platinum type medal 53.19% 67.97% 78.09%


  • For all species, the base capture rate is approximately equal to the probability of capture for a Level 14 Pokémon with no multiplier bonuses.
  • The highest theoretical multiplier that can be attained is ×47.6, which includes:
    • Using an Ultra Ball (×2.0)
    • Feeding a Golden Razz Berry (×2.5)
    • Throwing a Curveball (×1.7)
    • Making a perfect Excellent throw (×2.0)
    • Having a platinum type medal bonus (×1.4)
    • Encountering via Field, Special, or Timed Research (x2.0)
