Understanding Pokémon Catch Rates in Generation 9

Catching Pokémon is a fundamental mechanic in the Pokémon series, and in Generation 9 (Scarlet and Violet), the underlying mechanics of how likely a Pokémon is to be caught remain largely consistent with previous generations. The probability of successfully catching a wild Pokémon depends on several factors, all of which are factored into a complex formula. This calculator helps you estimate your chances of catching a specific Pokémon under various conditions.

The Catch Rate Formula Explained

The core of the catch rate calculation involves a value called the "catch factor." This factor is determined by the following inputs:

  • Pokémon's Base Catch Rate: Each species has a unique base catch rate, ranging from 0 to 255. A higher base catch rate means the Pokémon is generally easier to catch.
  • Pokémon's Current HP: The lower the Pokémon's current HP is compared to its maximum HP, the higher your chance of catching it. A severely weakened Pokémon is much more susceptible to capture.
  • Status Conditions: Inflicting a status condition like Sleep or Freeze significantly increases the catch rate. Poison, Burn, or Paralysis also provide a boost, though less than sleep or freeze.
  • Ball Modifier: Different Poké Balls have different multipliers. Standard Poké Balls have a multiplier of 1, while Great Balls and Ultra Balls offer increased chances. Specialized balls like Net Balls, Dive Balls, and Repeat Balls offer even higher multipliers under specific conditions (e.g., for certain types, or if you've caught the Pokémon before).
  • Critical Capture: In Generation 9, a Critical Capture can occur when attempting to catch a Pokémon. If successful, it significantly boosts the catch rate, making the capture almost guaranteed.

How the Calculator Works

This calculator takes your input for each of these factors and applies the Gen 9 catch rate formula. The formula essentially calculates a "catch modifier" based on your inputs. This modifier is then used to determine the probability of the Pokémon being caught.

The general formula, simplified, looks something like this:

Ball Factor * Status Factor * HP Factor * Critical Capture Factor

This results in a "catch throw value." If this value is greater than or equal to 255, the Pokémon is guaranteed to be caught. Otherwise, the game performs a series of random checks (often involving dividing the catch throw value by a random number) to see if the Pokémon breaks free.

Example Calculation

Let's say you're trying to catch a strong Pokémon like a Garchomp.

  • Garchomp's Max HP is typically around 107.
  • Garchomp's Base Catch Rate is 45.
  • You've weakened it significantly, and its Current HP is only 1.
  • You've put it to Sleep (Status Condition multiplier: 2).
  • You're using an Ultra Ball (Ball Type multiplier: 2).
  • You're not aiming for a Critical Capture (Critical Capture multiplier: 1).

With these inputs, the calculator will determine your approximate catch rate. In this scenario, with the Pokémon at very low HP and asleep, caught with an Ultra Ball, your chances are extremely high.

Understanding these mechanics can help you strategize your battles and ensure you add your desired Pokémon to your team with fewer frustrations.

If not, it checks further. // A simpler probability estimation: var probability = 0; if (catchFactor >= 255) { probability = 100; } else { // This is a very rough approximation. The real calculation involves dividing by a random number. // We'll use a scaled probability based on the catchFactor. probability = Math.min((catchFactor / 255) * 100, 99); } // Special cases for ball multipliers // Net Ball: 2x for Bug/Water. This calculator uses a flat multiplier. // Dive Ball: 2.5x for Water. // Repeat Ball: 2.5x if already owned. // Nest Ball: Varies by level. Lower level = higher multiplier. // Heavy Ball: Varies by weight. Heavier = higher multiplier. // These advanced ball mechanics would require more inputs. var resultHTML = "
