Catch Rate Calculator

Gen V+ capture formula. Conditional balls (Net, Dive, Repeat, Dusk, Quick) use their best-case multiplier.

Max HP

Base catch rate (3–255)

Current HP: 20 / 100

Ball

Status

Result

Overall catch chance

30.6%

Per-shake chance: 74.4%

Capture value (a): 78.0
Ball: Ultra Ball ×2
Status: None ×1

a = ((3×maxHP − 2×currentHP) × catchRate × ball / (3×maxHP)) × status. If a ≥ 255 the catch is guaranteed; otherwise shake value b = 1048560 / √(√(16711680 / a)), and overall chance = (b/65535)⁴.
