Catch rate (GO)

The calculation of catch rate is among the several mechanics that differ in Pokémon GO compared to the core series. Every 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.
==Calculation==
The chance for a thrown Poké Ball of successfully capturing a wild Pokémon, P, is Catch Mechanics
: P = 1 - \left(1 - \dfrac{baseCaptureRate}{2 \times CPM} \right)^{modifier}
where
* baseCaptureRate is the base capture rate of the wild Pokémon's species.
* CPM is the corresponding to the wild Pokémon's Power Up level.

When capturing Pokémon using a peripheral device, such as the Pokémon GO Plus or Poké Ball Plus, only the Ball and Medal modifiers are applied. While past devices were only able to use regular s, the Pokémon GO Plus + is the first device that can use Great Balls and Ultra Balls.
For these encounters, where only the Premier Ball can be used, Pokémon is guaranteed capture on the first ball that hits, bypassing the catch rate calculation. These encounters include
* from s or Team GO Rocket
* Any Shadow Pokémon from 
==Target ring colors==
The color of the target ring allows players to gauge the probability of a successful capture, factoring in all bonuses for modifier except for Throw, Curveball, and increases in Ball multiplier when using Premier Balls. Switching Poké Balls or feeding Berries may change the color of the ring. The greener the ring, the higher the catch rate; the redder it is, the lower the catch rate.

==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. Every time a Poké Ball is thrown, there is a flat 1% chance that it will bypass catch rate calculations and guarantee a capture.bmenrigh on X If the Poké Ball hits the target ring when the ring is at its smallest possible size, a critical capture is guaranteed, except for certain cases such as encounters from high-tier raids.Confirmed critical catches - /r/TheSilphRoad on Reddit Instead of shaking three times, a thrown Poké Ball will only shake once, and the Pokémon will be confirmed caught. XP bonuses such as from Great or Curveball throws are still included.
==Examples==
===Poké Balls and Berries===
Consider a wild with 343 , 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 modifiers, the catch rate will be \frac{20\%}{2 \times 0.49985844} \approx 20.006\%.
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.
	 	 	
	20.01%	28.45%	36.01%
	28.45%	39.48%	48.81%
	31.58%	43.40%	53.18%
	42.77%	56.70%	67.24%
===Throw technique===
Consider a wild 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 \frac{30\%}{2 \times 0.56675452} \approx 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 modifiers will be averaged between the highest and lowest possible values.
 	None 	Curveball
None(×1.0) 	26.47%	40.70%
Nice!(×1.15) 	29.78%	45.17%
Great!(×1.5) 	36.94%	54.34%
Excellent!(×1.85)	43.38%	61.97%
===Medals===
Let's now consider a wild 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 \frac{50\%}{2 \times 0.59740001} \approx 41.85\%.
The following table shows the effect on catch rate via medals for each Poké Ball type, assuming no other bonus modifiers.
	 	 	
	41.85%	55.65%	66.18%
	44.92%	59.12%	69.66%
	47.82%	62.31%	72.78%
	50.58%	65.25%	75.57%
	53.19%	67.97%	78.09%
==Trivia==
* For all species, the base capture rate is approximately equal to the probability of capture for a Level 14 Pokémon with no modifier bonuses.
* The highest theoretical modifier 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 (×2.0)
