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? 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.



Approximation of current HP:



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

Gender:


Your Pokémon's gender:



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.

@celestialVulpine: The raw formula and all the math involved are explained on the Gen III/IV capture mechanics page linked near the top of the page!

celestialVulpine

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

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

emiliano

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.

It is with immense gratitude that I reflect on the importance of this website in my life. Since I discovered it, it has become an invaluable source of information and resources that have helped me in many areas. The wealth of content available is truly impressive, and with each visit, I feel inspired by the new knowledge I acquire. The interactions with other users are also extremely valuable, as they provide an environment for collaborative learning. In such a dynamic world, where it is easy to feel lost or uninformed, having access to a space that promotes the exchange of ideas and personal growth is a true gift. Therefore, expressing my gratitude for this website is just one way of acknowledging the positive impact it has had on my journey.

Found your page, u can just delete both these comments.
Btw you rock! Thank you for this!

Steven Mattero

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…

I like the catch rate calculator
