Pokemon Calculator Catch Rate

This calculator helps you estimate the probability of catching a Pokémon based on its base catch rate and various in-game modifiers.

Understanding Pokémon Catch Rates

Catching Pokémon is a fundamental aspect of the Pokémon franchise. The success of your attempt depends on several factors, primarily the Pokémon's inherent difficulty to catch, your level advantage, the type of Poké Ball you use, and any status conditions the target Pokémon might be under.

Key Factors:

• Base Catch Rate: Each Pokémon species has a unique base catch rate, ranging from 0 to 255. Pokémon with higher base catch rates are generally easier to catch.
• Level Difference: While not a direct multiplier in all formulas, the level of your Pokémon and the wild Pokémon can sometimes influence catch mechanics, especially in older generations or specific scenarios. For this calculator, we're considering the target Pokémon's level as a factor influencing the overall difficulty.
• Poké Ball Type: Different Poké Balls offer varying bonuses to your catch attempt. The standard Poké Ball has a modifier of 1, while stronger balls like the Great Ball (1.5x), Ultra Ball (2x), and Master Ball (effectively 255x, but represented here by a high modifier for calculation purposes) significantly increase your chances.
• Status Conditions: Inflicting status conditions like Sleep or Paralysis on a wild Pokémon can dramatically increase your catch rate. A sleeping or frozen Pokémon offers a bonus of 2x, while poisoned, burned, or paralyzed Pokémon offer a 1.5x bonus.
• Environmental/Situational Modifiers: Certain Poké Balls are more effective in specific environments. For instance, Dusk Balls are more effective at night or in caves, and Dive Balls are more effective when underwater. These provide additional multipliers.

How the Calculation Works (Simplified):

The core idea is to determine a "modified catch rate" which is then compared against a random number. A simplified formula often used in calculations looks something like this:

Effective Catch Rate = ( (3 * MaxHP - 2 * CurrentHP) * BaseCatchRate * BallModifier * StatusModifier * OtherModifiers ) / (3 * MaxHP)

However, for a more direct probability calculation that aligns with common understanding and simplified game mechanics for many generations, we can use a formula that combines these multipliers to produce a direct catch chance percentage. A common approximation involves:

Catch Chance % = ( ( ( (3 * TargetLevel - 2 * TargetLevel) * BaseCatchRate * BallModifier * StatusModifier * OtherModifiers ) / (3 * TargetLevel) ) / 255 ) * 100

This calculator uses a generalized approach to estimate this probability, considering the interplay of the provided modifiers to give you a clearer picture of your chances.

Example Calculation

Let's say you're trying to catch a Level 30 Pokémon with a Base Catch Rate of 45. You're using an Ultra Ball (modifier 2.0), the Pokémon is Asleep (modifier 2.0), and you're in a cave at night using a Dusk Ball (modifier 1.5).

• Pokémon Catch Rate: 45
• Your Pokémon's Level: 50 (This is less relevant in many modern catch rate calculations, but can be factored in for some specific mechanics or older games. We'll use Target Level as primary for this example.)
• Target Pokémon's Level: 30
• Poké Ball Modifier: 2.0 (Ultra Ball)
• Status Condition Modifier: 2.0 (Asleep)
• Other Modifiers: 1.5 (Dusk Ball at night/cave)

Using these values, you'd input them into the calculator above to see your estimated catch probability.
