Gen III/IV Catch Rate Calculator

Other catch rate calculators: Gen I, Gen II, Gen V, Gen VI/VII, Gen VIII, Gen IX

To approximate your chances of catching any Pokémon in the third- and fourth-generation Pokémon games, enter the appropriate information below. To learn more about how this works, see the Gen III/IV Capture Mechanics page.

Shadow Pokémon? No Yes (Colosseum) Yes (XD) If you are playing Pokémon Colosseum or Pokémon XD: Gale of Darkness for the GameCube and this Pokémon is a Shadow Pokémon, select the appropriate option.

Pokémon:

Pokémon's level:

Approximation of current HP:
% HP left
Exactly 1 HP (using False Swipe)

Ball:

Status:
Note that in Ruby and Sapphire only, if the Pokémon is badly poisoned, it does not count as poisoned.

Your Pokémon's level:

Current turn:

Are you fishing?

Are you underwater using Dive (R/S/E) or fishing/surfing (D/P/Pt/HG/SS)?

Do you have this Pokémon registered in your Pokédex?

Is it nighttime or are you inside a cave?

Show detailed report? If checked, you will see the results for each possible HP IV if they would yield different results; otherwise, you'll see the overall chance assuming you know nothing about the IV. This is only very meaningful at full or exactly 1 HP, since the approximation of the Pokémon's current HP is not exact.

Hi im wondering how the Safari Zone Machanics affect the catch rate? Would throwing a rock be equivalent to HP of 50% ? But throwing bait and no rock is having the opposite affect I believe. I couldn't find any precise info on this…

calculator says 1.598% catch rate and at least a 95% chance of catching it within 186 balls, but I've reloaded the game at least 500 times with no result. I hate statistics.

Bruh, Articuno had a 2.833% chance and it took 401 ultra balls before I gave up and used a master ball.
I had a 99.999% chance of catching him by then

This is awesome, thank you so much for making this!!

Do you think you could include the raw formula for people to figure out how it works?
I'm a nerd who loves this kinda math and I'd love to use this to learn how the catching formula works & where to plug things in at
