Use catch odds after checking stats or defensive matchups. The result updates in the browser while the page URL stays clean for search and sharing.

If a specific game mode uses extra catch modifiers, keep the base species catch rate and add the known multiplier in the other modifier field.

For catch percentage calculator searches, compare the one-throw result with the 3-ball chance. For PokeMMO or ROM hacks, add any known custom multiplier instead of changing the species catch rate.

Gen 2, Gen 3, Pokemon Z-A, and fan formats can differ in edge cases. When you are unsure, use the output as a planning estimate rather than a guaranteed in-game catch result.

Result interpretation

The catch chance is the estimated probability that one thrown ball catches the Pokemon with the selected HP, ball, status, and modifiers.

Formula

The calculator estimates the modified catch value from HP, species catch rate, ball bonus, status bonus, and other modifiers, then converts that value into four successful shake checks.

Common uses

Compare ball choices, check how much sleep or paralysis helps, and see whether lowering HP further is worth another turn.

Catch percentage checks

Searches for catch calc, catch percentage calculator Pokemon, and Pokemon catching calculator usually need the same answer: one-ball odds, expected balls, and the chance across several throws.

Game-specific modifiers

For Gen 2, Gen 3, PokeMMO, Pokemon Z-A, or ROM hack checks, treat this as a base estimate unless the exact custom capture modifier is known and entered separately.

FAQ

What catch rate should I enter?

Enter the Pokemon species catch rate from 1 to 255. Higher catch rates are easier to catch.

Does lowering HP matter?

Yes. The formula increases the modified catch value as current HP gets lower, so 1 HP gives better odds than full HP.

Why is this an estimate?

Pokemon games can add generation-specific, ball-specific, badge, encounter, or special-case modifiers. Use the other modifier field when you need to include an extra known multiplier.

Can I use this for PokeMMO or newer Pokemon games?

Use it as a catch percentage estimate when the game follows main-series style catch math. If a game has its own modifier, enter that known multiplier in the other modifier field.

Can I use this for Pokemon Z-A catch rate checks?

Use it only as an estimate unless you have confirmed Pokemon Z-A-specific capture modifiers. Keep the species catch rate as the base input and add any known game-specific multiplier separately.

Is this a Pokemon catch percentage calculator?

Yes. The main result is the estimated one-ball catch percentage, with expected balls and a three-ball chance to make repeated attempts easier to compare.
