Introduction

This Pokémon catch rate calculator tells you the exact chance of catching any Pokémon in a single throw. Pick your Pokémon, choose a Poké Ball, set the HP and status condition, and get your result right away. The tool works for every main series game from Generation III through Generation IX.

Catch rates in Pokémon depend on many things at once. The wild Pokémon's base catch rate, its remaining HP, its status condition, and the type of ball you use all change your odds. Some games add even more factors like Critical Capture, Capture Power, and the Catching Charm. This calculator handles all of them so you don't have to do the math yourself.

You can also compare every Poké Ball side by side to find the best one for your situation. The tool shows how many throws you need on average, your cumulative odds over multiple throws, and a full breakdown by HP level. Whether you are trying to catch a legendary with a 3 catch rate or a common Pokémon in tall grass, this calculator gives you clear numbers you can trust. If you need to check how much damage your moves deal during the weakening process, try our Pokémon Damage Calculator. And to verify your Pokémon's hidden stats before or after the catch, use our Pokémon IV Calculator.

How to Use Our Pokémon Catch Rate Calculator

Enter details about the wild Pokémon, your ball, and battle conditions below. The calculator will show your chance to catch the Pokémon in one throw, how many throws you need on average, and how every ball compares.

Pokémon Name: Type the name of the wild Pokémon you want to catch. A list of suggestions will appear as you type. The base catch rate updates automatically.

Form: If the Pokémon has more than one form, pick the correct one from the dropdown. Different forms can have different types and catch rates.

Wild Pokémon Level: Enter the level of the wild Pokémon from 1 to 100. This affects Nest Ball and Level Ball results.

Generation: Pick the game generation you are playing. The catch rate formula changes between generations, and some balls and features are only available in certain ones.

HP Input Mode: Choose whether to set HP as a percentage or as exactly 1 HP. Pick "Exactly 1 HP" if you used False Swipe or Hold Back.

HP Remaining: Use the slider or type a number from 1 to 100 to set how much HP the wild Pokémon has left. Lower HP means a higher catch chance. You can also click a quick preset button.

Status Condition: Select the status the wild Pokémon currently has. Sleep and Freeze give the biggest boost. No status gives no bonus.

Poké Ball Selection: Choose the ball you plan to throw. The calculator uses this ball for your main result, the HP chart, and the cumulative throw table.

Show All Balls: Turn this on to see a ranked chart and table that compares the catch chance of every available ball at once.

Situational Modifiers: Check or fill in any conditions that apply to your battle. These include whether the target is a Water or Bug type (Net Ball), whether you are fishing (Lure Ball), underwater or surfing (Dive Ball), in a cave or at night (Dusk Ball), and whether the Pokémon is already in your Pokédex (Repeat Ball). To check type matchups and weaknesses before you battle, our Pokémon Type Calculator can help.

Turn Number: Enter what turn of the battle you are on. This affects Quick Ball and Timer Ball. Quick Ball works best on turn 1. Timer Ball gets stronger each turn.

Your Pokémon's Level: Enter the level of the Pokémon you have in battle. This is used for the Level Ball calculation.

Your Pokémon's Name and Gender: Enter the name and gender of your battling Pokémon, and set the wild Pokémon's gender. The Love Ball works only when both Pokémon are the same species but opposite genders.

Pokédex Registered Count: Enter how many Pokémon you have registered in your Pokédex. A higher count makes Critical Capture more likely in Gen V and later.

Catching Charm: Check this box if you have the Catching Charm key item. It gives an extra boost to your Critical Capture odds.

Capture Power Level (Gen IX only): Select your active Capture Power level from a meal or sandwich. Higher levels give a bigger catch rate boost.

Off-Guard Bonus (Gen IX only): Check this box if you started the battle by surprising the Pokémon from behind.

Shadow Pokémon (Gen III–IV only): If you are playing Pokémon Colosseum or XD: Gale of Darkness, select the correct game. Shadow Pokémon use a different catch formula.

Calculate Button: Press this to run the calculator and see all results. Results also update automatically when you change any input.

Reset All Inputs: Press this to set every field back to its default value.

How Catch Rates Work in Pokémon Games

Every wild Pokémon has a base catch rate. This is a number from 3 to 255. A higher number means the Pokémon is easier to catch. A lower number means it is harder. For example, Magikarp has a catch rate of 255, so it is very easy to catch. Legendary Pokémon like Mewtwo have a catch rate of just 3, making them some of the hardest to catch in the game.

The game uses a formula to decide if your throw succeeds. Three main things affect your odds: the Pokémon's remaining HP, its status condition, and the type of Poké Ball you use. Lowering the wild Pokémon's HP as much as possible gives you the best chance. Using moves like False Swipe to leave it at 1 HP is a common strategy. Putting the target to sleep or freezing it also helps a lot, since those status conditions multiply your catch rate by 2.5× in most games. To plan your damage output and make sure you don't accidentally knock out the target, use our Pokémon Damage Calculator.

Different Poké Balls have different ball multipliers. A regular Poké Ball has a 1× multiplier. A Great Ball has 1.5×, and an Ultra Ball has 2×. Special balls like the Dusk Ball (3× at night or in caves) or Quick Ball (5× on the first turn) can be even better when their conditions are met.

Critical Capture and Generation Differences

Starting in Gen V, the games added Critical Capture. This is a special throw where the ball only needs to shake once instead of three times. Your odds of getting a Critical Capture go up as you register more Pokémon in your Pokédex. The Catching Charm key item boosts this even further.

The catch rate formula has changed slightly across generations. Gen III–IV games use a different shake check than Gen V and later. Gen IX (Pokémon Scarlet and Violet) added new bonuses like Capture Power from meals and sandwiches, plus an Off-Guard bonus when you surprise a Pokémon from behind. The calculator above accounts for all of these differences. If you want to understand how probability works at a deeper level, our Odds Calculator and Percentage Calculator can help with the underlying math.

Tips to Catch Pokémon Faster

To get the best catch rate on any Pokémon, lower its HP to 1 with False Swipe, put it to sleep, and pick the strongest ball for the situation. A Quick Ball on turn one often beats an Ultra Ball. At night, a Dusk Ball is one of the best choices. For Water-type or Bug-type Pokémon, the Net Ball gives a 3.5× bonus in Gen VI and later. Use the calculator above to find the exact odds for your situation and pick the right ball every time. After you've made the catch, check your new Pokémon's individual values with our Pokémon IV Calculator and figure out its type strengths and weaknesses using the Pokémon Type Calculator.

If you enjoy competitive Pokémon PVP battles, tracking your performance with a KD Calculator or a Win Rate Calculator can help you measure your improvement over time. And for other gaming tools, check out our Poker Odds Calculator for card game probabilities or the Minecraft Enchantment Calculator if you play across multiple titles.


Frequently asked questions

What is a base catch rate?

A base catch rate is a number from 3 to 255 that every Pokémon species has. A higher number means the Pokémon is easier to catch. For example, Magikarp has 255 (very easy) and Mewtwo has 3 (very hard). The calculator loads this number automatically when you pick a Pokémon.

Why did my catch rate change when I switched generations?

The catch formula is different in each generation. Ball multipliers, status bonuses, and shake checks all change between games. For example, Sleep and Freeze give a 2× bonus in Gen III–IV but 2.5× in Gen V and later. Always set the generation to the game you are actually playing.

What does the ball multiplier number mean?

The ball multiplier is the number the game multiplies your catch rate by when you use that ball. A Poké Ball is 1×, a Great Ball is 1.5×, and an Ultra Ball is 2×. A higher multiplier gives you a better chance to catch the Pokémon.

What is the best Poké Ball to use?

It depends on the situation. Use the "Show All Balls" toggle in the calculator to compare every ball at once. In general, Quick Ball on turn 1, Dusk Ball at night or in caves, and Net Ball on Water or Bug types are often better than an Ultra Ball.

What does average throws mean in the results?

Average throws is the expected number of times you need to throw the ball before you catch the Pokémon. It equals 1 divided by your single-throw catch probability. For example, if your catch chance is 25%, you need about 4 throws on average.

How does the cumulative catch probability table work?

It shows your total chance of catching the Pokémon within a set number of throws. Each throw is independent. The formula is 1 minus (1 minus your single-throw chance) raised to the power of the number of throws. More throws means a higher total chance.

What is Critical Capture?

Critical Capture is a special throw added in Gen V. The ball only shakes once instead of three times. Your chance of getting one goes up as you register more Pokémon in your Pokédex. The Catching Charm item boosts it further. It does not exist in Gen III or IV.

Why should I use False Swipe before throwing a ball?

False Swipe always leaves the target with at least 1 HP. Lower HP means a much higher catch rate. Dropping a Pokémon to 1 HP gives you the best possible odds. Select "Exactly 1 HP" in the HP Input Mode to see the difference.

Does the calculator work for Pokémon Legends Arceus?

No. This calculator covers the main series games from Generation III through Generation IX. Pokémon Legends: Arceus uses a completely different catching system that is not based on the standard formula.

What are the situational modifier checkboxes for?

They tell the calculator when a special ball condition is active. For example, checking "Nighttime / in a cave" activates the Dusk Ball bonus. Checking "Target is Water- or Bug-type" activates the Net Ball bonus. Only check the ones that match your current battle.

How does the HP IV breakdown work?

HP IVs change a Pokémon's max HP, which slightly changes the catch rate result due to rounding in the formula. Turn on the toggle to see your catch probability for every HP IV from 0 to 31. This matters most when HP is at 100% or exactly 1.

What is the Catching Charm?

The Catching Charm is a key item you can earn in some games. It increases your chance of getting a Critical Capture by about 20%. Check the box in the calculator if you have it. It only works in Gen V and later.

What is Capture Power in Gen IX?

Capture Power is a boost you get from eating meals or sandwiches in Pokémon Scarlet and Violet. It has three levels that multiply your catch rate by 1.1×, 1.2×, or 1.3×. Set your current level in the Gen IX section of the calculator.

What does the Off-Guard bonus do?

In Gen IX, if you start a battle by sneaking up behind a wild Pokémon, you get an Off-Guard bonus. This doubles a part of the catch formula, making the Pokémon easier to catch. Check the box if you surprised the Pokémon from behind.

How do Shadow Pokémon catch rates work?

Shadow Pokémon in Pokémon Colosseum and XD: Gale of Darkness use different formulas. In Colosseum, the ball multiplier is forced to 1×. In XD, a different shake formula is used. Select the correct game in the Shadow Pokémon section if this applies to you.

Why does the Master Ball show 100% catch rate?

The Master Ball always catches any Pokémon without fail. It has no random chance involved. The calculator shows it as 100% guaranteed because that is how it works in every game.

Can I use this calculator on my phone?

Yes. The calculator is fully responsive and works on phones, tablets, and computers. All inputs, charts, and tables adjust to fit your screen size.

How does the Timer Ball work?

The Timer Ball gets stronger the longer the battle lasts. Its multiplier increases each turn up to a maximum of 4×. In Gen V and later it gains 0.3× per turn, so it maxes out around turn 11. Enter your current turn number in the calculator to see the exact bonus.

Why is my catch probability different from what I expected?

Many small factors affect the result. Make sure your generation, HP percentage, status condition, ball choice, and all situational checkboxes are set correctly. Even a small change like switching from Gen IV to Gen V changes the formula and your odds.

What does the Show All Balls comparison assume?

When comparing all balls, the calculator assumes favorable conditions are met for each special ball. For example, it assumes nighttime for Dusk Ball and Water or Bug type for Net Ball. This lets you see each ball at its best so you can pick the right one.
