Catch Rate Calculators

Every mainline game uses one of a few capture formulas. Generation I rolls against the ball and then against the target's HP, Generation II uses a single HP-and-ball formula, Generations III and IV turn a modified catch rate into four shake checks, and Generation V onward adds critical captures and a smoother shake curve. Each calculator uses the formula and ball bonuses of its own generation.

Choose a Pokémon, set its level and remaining HP, then pick a ball and status condition. You get the chance of catching it with one throw and the cumulative chance over several. Catch rates and max HP can be edited when you know the exact values for your target.
