How to Use This Calculator
Enter each requested value using the displayed unit. Review the assumptions and update the defaults when your situation differs.
Formula & Methodology
The calculator applies the visible formulas directly to the entered values. Supporting outputs expose important intermediate results.
Worked example
Lowering the target's HP, using a stronger ball and applying sleep or freeze generally increases the estimate.
Pokémon capture formulas differ by game and generation, and some balls, encounters, abilities and story captures use special rules. This is a transparent planning approximation.
Unofficial fan-made calculator. Verify generation-specific mechanics when exact in-game probability matters.
