Pokemon Go Catch Mechanics

Catch Mechanics

Every Go player quickly realizes that some Pokémon are harder to catch than others. Why? What calculations happen behind the scene when a PokeBall hits the target?

After an enormous and collaborative research effort, the mechanics of Pokémon Go Capture Rate are now well understood.

Target Ring

The target ring offers a quick visual estimate of a Pokémon’s Capture Rate. Its color ranges from a vibrant green to a vibrant red, which corresponds to these Capture Rate thresholds:

Ring Color Capture Rate
Green 66~100%
Yellow 36~65%
Orange 26~35%
Red 0~25%

Factors that affect catch rate

  • Pokémon species
  • Pokémon level
  • Type of Pokeball used
  • Whether Razzberry was applied
  • Curve ball bonus
  • Nice / great / excellent throws

Factors that don’t affect catch rate

  • Trainer level
  • Number of captures
  • Pokémon Type
  • Pokémon’s IV
  • Pokémon’s mood
  • When PokeBall lands outside of targeting ring
  • Number of attempts
  • Duration
  • Speed of travel
  • Time of day
  • Weather and other acts of god

Base Capture Rate

Each Pokémon has a Base Capture Ratedetermined by its species. It reflects the Capture Rate of a Level 14 Pokémon:

Capture Rate

Base Capture Rate is then modified by the Pokémon Level using the formula:

LVL 56% 48% 40% 32% 24% 16%
1 100% 100% 100% 100% 100% 85%
2 100% 100% 100% 96% 72% 48%
3 100% 100% 93% 74% 56% 37%
4 100% 94% 78% 63% 47% 31%
5 96% 83% 69% 55% 41% 28%
6 87% 75% 62% 50% 37% 25%
7 80% 69% 57% 46% 34% 23%
8 75% 64% 53% 43% 32% 21%
9 70% 60% 50% 40% 30% 20%
10 66% 57% 47% 38% 28% 19%
11 63% 54% 45% 36% 27% 18%
12 61% 52% 43% 35% 26% 17%
13 58% 50% 42% 33% 25% 17%
14 56% 48% 40% 32% 24% 16%
15 54% 46% 39% 31% 23% 15%
16 52% 45% 37% 30% 22% 15%
17 51% 44% 36% 29% 22% 15%
18 49% 42% 35% 28% 21% 14%
19 48% 41% 34% 27% 21% 14%
20 47% 40% 33% 27% 20% 13%
21 46% 39% 33% 26% 20% 13%
22 45% 38% 32% 26% 19% 13%
23 44% 37% 31% 25% 19% 12%
24 43% 37% 31% 24% 18% 12%
25 42% 36% 30% 24% 18% 12%
26 41% 35% 29% 23% 18% 12%
27 40% 35% 29% 23% 17% 12%
28 40% 34% 28% 23% 17% 11%
29 39% 33% 28% 22% 17% 11%
30 38% 33% 27% 22% 16% 11%

For the evolved form of a Pokémon that evolves only once, its Base Capture Rate is 1/2.5 of base form. For the evolved form of a Pokemon that evolves in two stages, its Base Capture Rate is halved in each stage. Example:
