What is the SWSH Catch Rate Calculator?
The SWSH (Sword and Shield) Catch Rate Calculator is a specialized tool designed to help Pokémon Trainers estimate their chances of successfully capturing a wild Pokémon. While the core mechanics of catching Pokémon have evolved across game generations, this calculator focuses on the principles relevant to modern Pokémon games, particularly those that might interact with or be conceptually similar to the systems in Pokémon Sword and Shield, and crucially, how these principles apply within the popular mobile game, Pokémon GO. Understanding the factors that influence a catch is vital for trainers aiming to complete their Pokédex, collect rare Pokémon, or simply optimize their item usage.
This calculator is beneficial for:
- New Trainers: To grasp the basics of Pokémon catching mechanics.
- Experienced Trainers: To fine-tune their strategies, especially in Pokémon GO where precise throws and item usage are critical.
- Collectors: To maximize their chances of catching specific or rare Pokémon encountered in the wild or during events.
- Competitive Players: To understand the odds when facing challenging wild encounters.
Common misunderstandings often revolve around the complexity of the formula, the specific values for different Pokémon, and the exact impact of bonuses like berries, ball types, and throw accuracy. This tool aims to demystify these elements.
Catch Rate Formula and Explanation
The catch rate formula in Pokémon games can be quite intricate, evolving over generations. For the purpose of this calculator, we are simplifying it to reflect a common understanding and application, particularly relevant to the mechanics seen in games like Pokémon Sword and Shield and adaptable to Pokémon GO's encounter system.
Simplified Catch Rate Formula:
Final Catch Rate (%) = (Modified Catch Rate / Shake Check Value) * 100
Where:
Modified Catch Rate = ( ( (Base Catch Rate * Ball Bonus * Berry Bonus) * Level Bonus ) + IV Bonus ) * Throw Bonus
(Note: This is a conceptual representation. Actual game formulas can have more nuances, especially regarding rounding and specific coefficient values.)
Variables:
Catch Rate Formula Variables
| Variable |
Meaning |
Unit / Range |

4 (Often) |
| Critical Capture Bonus |
A special bonus that significantly increases catch rate, often triggered randomly or under specific conditions (less common in GO). |
Multiplier (Decimal) |
N/A for basic GO calculations, or a high multiplier (e.g., 2.5x) in main series. |
Practical Examples
Let's illustrate with a couple of scenarios:
Example 1: Catching a Common Pokémon
Scenario: You encounter a common Pokémon like a Pidgey with a base catch rate of 255. Your Pokémon is Level 20, and the wild Pidgey is also Level 20 (Level Difference = 0). You're using a standard Poké Ball, no berry, and land a Great Throw.
- Inputs:
- Base Catch Rate: 255
- Level Difference: 0
- Ball Type: Poke Ball (Ball Bonus = 1.0)
- Berry Type: None (Berry Bonus = 1.0)
- Throw Bonus: Great Throw (Throw Multiplier = 1.5)
- IVs: Assume 30 (IV Bonus = ~30)
Calculation:
Modified Catch Rate ≈ (((255 * 1.0 * 1.0) * 1.0) + 30) * 1.5 ≈ (255 + 30) * 1.5 ≈ 427.5
Final Catch Rate ≈ (427.5 / 4) * 100 ≈ 106.875%
Result: You have a very high chance (effectively 100% in most practical terms for common Pokémon) to catch this Pidgey.
Example 2: Attempting a Rare Pokémon
Scenario: You encounter a rare Pokémon like a Dratini with a base catch rate of 45. Your Pokémon is Level 25, and the wild Dratini is Level 28 (Level Difference = -3). You're using a Great Ball, a Razz Berry, and land an Excellent Throw. The wild Dratini has perfect IVs (45).
- Inputs:
- Base Catch Rate: 45
- Level Difference: -3
- Ball Type: Great Ball (Ball Bonus = 1.5)
- Berry Type: Razz Berry (Berry Bonus = 1.2)
- Throw Bonus: Excellent Throw (Throw Multiplier = 2.0)
- IVs: 45 (IV Bonus = 45)
Calculation:
Modified Catch Rate ≈ (((45 * 1.5 * 1.2) * (Level Modifier for -3)) + 45) * 2.0
(Level modifier for -3 is complex, let's assume it reduces the rate significantly, perhaps to 0.5x for simplicity in this conceptual example).
Modified Catch Rate ≈ ((81 * 0.5) + 45) * 2.0 = (40.5 + 45) * 2.0 = 85.5 * 2.0 = 171
Final Catch Rate ≈ (171 / 4) * 100 ≈ 42.75%
Result: With these bonuses, your chance to catch the Dratini is around 42.75%. This demonstrates how strategic use of items and throws significantly improves odds against tougher catches.

Key Factors That Affect SWSH Catch Rate
- Pokémon Base Catch Rate: This is fundamental. Legendary Pokémon have notoriously low base catch rates, making them harder to catch. Common Pokémon have high rates.
- Ball Type Multiplier: Specialized balls like Ultra Balls offer higher multipliers than basic Poké Balls, directly increasing the chance. Master Balls offer a 100% catch rate.
- Berry Usage: Razz Berries (and their stronger variants) provide a significant boost to the catch rate, making them invaluable for rare encounters.
- Throw Accuracy (Nice, Great, Excellent, Curveball): Landing accurate throws grants substantial multipliers. Mastering curveballs and precise aiming is key.
- Level Difference: While more impactful in the main series games, a significant level disadvantage against the wild Pokémon can decrease your odds.
- Individual Values (IVs): Higher IVs provide a small but cumulative bonus to the catch rate, especially noticeable on Pokémon with otherwise low base rates.
- Critical Capture: A rare mechanic in main series games that drastically increases catch chance, but less relevant in Pokémon GO's standard encounters.
- Status Effects: While not directly in this formula, inflicting status conditions like Paralysis, Sleep, or Freeze can sometimes indirectly affect catch rates in certain game contexts.
FAQ
-
Q: What does "SWSH" stand for?
A: SWSH stands for Pokémon Sword and Shield, the main series games released for the Nintendo Switch. While this calculator focuses on general mechanics applicable to many Pokémon games and Pokémon GO, the abbreviation ties it to that generation's context.
-
Q: Is this calculator for Pokémon GO or the main series games?
A: This calculator uses a simplified model that adapts principles from the main series games (like Sword and Shield) to be most useful for Pokémon GO. The core mechanics of catch rate calculation are similar in concept across many Pokémon titles.
-
Q: How accurate is this calculator?
A: This calculator provides a highly accurate estimation based on widely understood mechanics. However, actual catch rates can have subtle variations due to specific game engine rounding, hidden modifiers, or unique event mechanics not accounted for in this simplified model.
-
Q: What is the base catch rate for my Pokémon?
A: Base catch rates vary significantly between Pokémon species. You can find this information on many reputable Pokémon fan sites and databases by searching for the specific Pokémon's name and "base catch rate".
-
Q: Does the calculator account for Critical Captures?
A: The basic version of this calculator focuses on standard throws and bonuses relevant to Pokémon GO. Critical Captures, while a feature in main series games, are not typically a standard mechanic in Pokémon GO encounters and are thus excluded from the primary calculation for simplicity.
-
Q: What if I don't know the wild Pokémon's IVs?
A: If you don't know the IVs, you can either leave the IV input at its default (often representing average IVs) or set it to 0 for a more conservative estimate. The actual IVs will affect the real catch rate.
-
Q: Can I use multiple bonuses at once?
A: Yes, this calculator assumes you can combine bonuses like a Great Ball, Razz Berry, and a Great Throw. The formula multiplies these effects to determine the modified catch rate.
-
Q: How does the Level Difference affect the catch rate?
A: A positive level difference (your Pokémon higher level than wild) generally increases catch rate slightly, while a negative difference (wild Pokémon higher level) decreases it. The exact modifier depends on the magnitude of the difference.
