Formula Used

The calculator uses a modern four-shake style estimate.

Adjusted catch rate: base catch rate plus adjustment, limited from 1 to 255.

HP factor: ((3 × max HP) - (2 × current HP)) ÷ (3 × max HP).

Modified catch value: HP factor × adjusted catch rate × ball modifier × status modifier.

If the modified value reaches 255, capture is treated as guaranteed.

Otherwise, shake value equals 65536 ÷ (255 ÷ modified value)0.1875.

Single throw chance equals (shake value ÷ 65536)4.

Repeated throw chance equals 1 - (1 - single throw chance)throws.

About This Calculator

A Pokeball catch rates calculator helps estimate capture success before each throw. It uses target health, species catch rate, ball bonus, status condition, and throw count. The result shows a single throw chance and a repeated throw chance. This helps compare tactics quickly.

Why Catch Rate Matters

Every species has a base catch rate. Higher values are easier to catch. Lower values need stronger balls, lower health, or better status effects. Health is also important. A weak target usually raises the final chance. Sleep and freeze often provide the strongest status bonus. Paralysis, burn, and poison are still useful.

Advanced Options

This tool includes custom ball modifiers and catch rate adjustments. These options help model special balls or house rules. Timer Ball can improve with turns. Quick Ball can help early. Dusk Ball can help in caves or at night. Net Ball can help against water or bug targets. Repeat Ball can help if the species is already registered.

Planning Better Throws

Use the calculator before spending rare balls. Start with the species catch rate. Then enter max HP and current HP. Pick the selected ball. Add the status bonus. Enter the number of planned throws. The calculator returns the chance for one throw. It also estimates the chance after several identical throws.

Reading The Result

A chance near one hundred percent means capture is almost certain. A low chance means more throws may be needed. Expected throws is an average value. Real battles can still vary because capture checks are random. The shake value is included for players who want deeper detail.

Practical Tips

Lower the target HP safely. Use False Swipe when available. Add sleep or freeze when possible. Choose balls that match the situation. Use Quick Ball on the first turn. Use Timer Ball during long battles. Use Dusk Ball in dark areas. These choices can raise capture odds without guessing.

Export And Records

The export buttons save the same values shown on screen. CSV is useful for spreadsheets. PDF is useful for simple reports. Keep records for difficult hunts. Compare different balls after each test. This can show which option gives the best value over time. Review entries before changing your battle plan.

FAQs

What is a Pokeball catch rate?

It is an estimated chance that one throw will capture the target. The value depends on HP, base catch rate, ball bonus, status condition, and special battle rules.

What does base catch rate mean?

Base catch rate is the species capture value. A higher number means easier capture. A lower number means the target is harder to catch.

Why does lower HP improve the result?

The formula rewards weaker targets. Lower current HP raises the HP factor. That increases the modified catch value and improves the final chance.

Which status gives the best bonus?

Sleep and freeze usually provide the strongest bonus in this calculator. Paralysis, burn, and poison still improve the chance compared with no status.

How does Timer Ball work here?

The Timer Ball modifier rises as turns pass. This calculator increases it gradually and limits it at a maximum value of four.

Can I use a custom ball value?

Yes. Choose Custom Modifier from the ball list. Then enter your preferred multiplier for special cases, fan rules, or different game assumptions.

What is repeated throw chance?

It estimates the chance of at least one capture across several identical throws. It assumes the same conditions remain unchanged for each throw.

Are results guaranteed in real battles?

No. The calculator estimates probability. Random checks can still fail many times, even when the displayed chance looks strong.
