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.

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.
