Catch Rate Calculatorin Pokémon Ghost Grey

Estimate catch odds per ball using Polished (Gen 2-style) mechanics.

Not all Pokémon are equally easy to catch - Legendary Pokémon often have catch rates as low as 3 (out of 255), while common Pokémon like Rattata have catch rates of 255. Understanding these odds helps you prepare the right balls and strategies before critical encounters.

Status conditions dramatically improve catch rates: Sleep and Freeze provide the biggest boost, while Paralysis, Burn, and Poison offer smaller improvements. Lowering HP is essential - at 1 HP with Sleep status and an Ultra Ball, even difficult Legendaries become catchable. Use this calculator to optimize your ball choice and avoid wasting limited resources like Master Balls on easily catchable Pokémon.

Selecting a Pokémon sets its base catch rate.

How can I increase my catch odds?
Status conditions improve catch rates the most — Sleep and Freeze give the biggest boost, followed by Paralysis, Burn, and Poison. Lowering HP to 1 plus a strong ball makes even Legendaries catchable.
