Catch Rate Calculator
Your Catch Rate Analysis
The Catch Formula Value (CFV) is calculated by multiplying the Pokémon's Base Catch Rate by several modifiers: Ball Type, Status Effect, Level Check, and Shiny status. This value is then used to determine the Effective Catch Rate (ECR), which represents the base probability of success for a single ball throw. The Success Chance is directly derived from the ECR, and the Average Times to Try is the inverse of the Success Chance.
What is the Catch Rate in Pokémon Legends: Arceus?
In Pokémon Legends: Arceus, the catch rate refers to the inherent probability that a wild Pokémon will be successfully captured when a Poké Ball is thrown at it. Unlike previous titles where this was the primary mechanic, Legends: Arceus blends this with an action-RPG combat system. Understanding the catch rate is crucial for efficient gameplay, whether you're aiming to fill your Pokédex or capture specific Pokémon for your team. The game's mechanics introduce several factors that modify this base probability, making a dedicated catch rate calculator for Pokémon Legends: Arceus invaluable for trainers.
This calculator helps you understand the likelihood of success in different scenarios, factoring in the Pokémon's condition, the ball you use, and even the level difference between your Pokémon and the wild encounter. It's particularly useful for high-difficulty catches or when trying to capture Shiny Pokémon. Many players misunderstand that simply having a strong Pokémon guarantees a catch; this calculator clarifies that the underlying Pokémon Legends Arceus catch mechanics are complex and influenced by multiple variables.
Pokémon Legends: Arceus Catch Rate Formula and Explanation
The core of the catch mechanic in Pokémon Legends: Arceus relies on a formula that determines a "Catch Formula Value" (CFV), which then influences the "Effective Catch Rate" (ECR). The final success chance is derived from the ECR.
The primary formula used for calculation is:
CFV = (Base Catch Rate) * (Ball Modifier) * (Status Modifier) * (Level Check Modifier) * (Shiny Modifier)
Where:
- Base Catch Rate: An intrinsic value assigned to each Pokémon species, indicating its base difficulty to catch (1-255).
- Ball Modifier: A multiplier based on the type of Poké Ball used. Certain balls have higher multipliers, especially unique Hisuian balls.
- Status Modifier: A multiplier that increases based on the status condition of the wild Pokémon (e.g., Sleep, Paralysis).
- Level Check Modifier: A multiplier applied if your Pokémon is significantly higher in level than the wild Pokémon.
- Shiny Modifier: A multiplier (typically 2.0x) applied if the wild Pokémon is Shiny, significantly increasing catch chance.
This CFV is then used to calculate the Effective Catch Rate (ECR), which directly translates to the percentage chance of success. A higher CFV leads to a higher ECR.
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Pokémon Level | The level of the wild Pokémon being encountered. | Level | 1 – 100 |
| Base Catch Rate | The Pokémon species' inherent catchability. | Unitless (1-255) | 1 – 255 |
| Ball Modifier | Multiplier based on the Poké Ball used. | Multiplier (x) | 1.0 – 3.5+ |

| Level Check Modifier | Multiplier based on level advantage of your Pokémon. | Multiplier (x) | 1.0 – 2.0 |
| Shiny Modifier | Multiplier if the Pokémon is Shiny. | Multiplier (x) | 1.0 or 2.0 |
| Catch Formula Value (CFV) | The intermediate calculated value before ECR. | Unitless | Varies significantly |
| Effective Catch Rate (ECR) | The final calculated probability of success per throw. | Unitless (0-1) | 0 – 1 |
| Success Chance (%) | ECR converted to a percentage. | Percent (%) | 0 – 100% |
| Average Times to Try | The average number of balls needed for success. | Count | 1+ |
Practical Examples
Let's see how the calculator works with some realistic scenarios:
Example 1: Catching a Standard Pokémon
You encounter a wild Gyarados at Level 50. It has a Base Catch Rate of 45. You decide to use an Ultra Ball and it's not Shiny. Your Pokémon is significantly higher level, giving you a Level Check Modifier of 1.5x. Gyarados has no status condition.
- Pokémon Level: 50
- Base Catch Rate: 45
- Ball Type: Ultra Ball (2.0x)
- Status: No Status (1.0x)
- Level Check Modifier: Significant Level Advantage (1.5x)
- Shiny Pokémon: No (1.0x)
Calculation: CFV = 45 * 2.0 * 1.0 * 1.5 * 1.0 = 135 ECR = CFV / (CFV + 255) = 135 / (135 + 255) = 135 / 390 ≈ 0.346 Success Chance = 0.346 * 100% ≈ 34.6% Average Times to Try = 1 / 0.346 ≈ 2.89
Result: You have approximately a 34.6% chance to catch the Gyarados with an Ultra Ball, requiring an average of about 2.89 throws.
Example 2: Catching a Shiny Pokémon with Status
You encounter a rare Shiny Hisuian Zoroark at Level 70. Its Base Catch Rate is 3. You use a Stealth Ball and successfully inflict Sleep on it. Your Pokémon has a major level advantage (2.0x).
- Pokémon Level: 70
- Base Catch Rate: 3
- Ball Type: Stealth Ball (2.2x)
- Status: Asleep (1.5x)
- Level Check Modifier: Major Level Advantage (2.0x)
- Shiny Pokémon: Yes (2.0x)
Calculation: CFV = 3 * 2.2 * 1.5 * 2.0 * 2.0 = 39.6 ECR = CFV / (CFV + 255) = 39.6 / (39.6 + 255) = 39.6 / 294.6 ≈ 0.134 Success Chance = 0.134 * 100% ≈ 13.4% Average Times to Try = 1 / 0.134 ≈ 7.46
Result: Despite the multipliers, the low base catch rate and the presence of Shiny status still make this a challenging catch. You have about a 13.4% chance, averaging around 7.46 throws. This highlights how critical the Base Catch Rate is.
How to Use This Catch Rate Calculator for Pokémon Legends: Arceus
- Enter Pokémon Level: Input the level of the wild Pokémon you are trying to catch.

Key Factors That Affect Catch Rate in Legends: Arceus
- Base Catch Rate: This is the most fundamental factor. Pokémon like Magikarp have very high base rates, making them easy to catch, while legendaries or pseudo-legendaries have extremely low base rates.
- Poké Ball Choice: Using stronger balls like the Ultra Ball or specialized Hisuian balls (Leaden, Gigaton, Stealth, etc.) provides significant multipliers, increasing your odds.
- Pokémon Status Conditions: Inflicting Sleep or Paralysis greatly increases your catch rate. Frozen and Burned also provide bonuses, though less commonly inflicted by players in a way that benefits catch rate directly.
- Level Advantage: Having a much higher-leveled Pokémon compared to the wild encounter provides a noticeable boost to your catch success. This encourages strategic encounters where you use Pokémon appropriate for the area.
- Shiny Pokémon: Encountering a Shiny Pokémon dramatically increases the catch rate multiplier, making them slightly easier to catch than their normal counterparts despite their rarity.
- Back Strikes/Stealth: While not directly factored into the core mathematical formula shown here, successfully initiating a battle via stealth (catching from behind without being detected) or initiating combat with a Pokémon of significantly higher level can sometimes offer situational advantages or change the encounter dynamics, though the direct numerical impact on the ball throw is captured by the Level Check and other modifiers.
- Area and Time (Indirect): Some balls (like the Dark Ball or specific Hisuian balls) have conditional effectiveness based on whether it's night/day or if you're in a cave. While the calculator might use a static modifier value, selecting the correct ball for the situation is key.
Frequently Asked Questions (FAQ)
The Base Catch Rate is an intrinsic value of a Pokémon species. The Success Chance is the final percentage probability of successfully catching it with a single throw, after all modifiers (ball, status, level, shiny) are applied.
No, Hisuian balls have varied modifiers. Some are designed for distance (Jet, Wing), weight (Heavy, Leaden, Gigaton), or stealth (Stealth), each with a unique multiplier.
Yes, indirectly. If your Pokémon is significantly higher level than the wild Pokémon, the "Level Check Modifier" increases your catch rate. The absolute level of your Pokémon doesn't matter as much as its level relative to the target.
Sleep provides a significant boost, typically a 1.5x multiplier to the catch rate calculation, making it one of the most effective status conditions for catching.
Yes, Shiny Pokémon have a 2.0x modifier applied to the catch rate calculation, effectively doubling your chances of success with any given throw compared to a non-Shiny of the same species and condition.
It's the inverse of the Success Chance percentage. If your success chance is 25% (0.25), you'll need an average of 1 / 0.25 = 4 throws to catch the Pokémon.
No, this calculator is specifically designed for the mechanics of Pokémon Legends: Arceus. Catch mechanics vary significantly between different Pokémon titles.
In Pokémon Legends: Arceus, a Pokémon typically only has one primary status effect at a time that affects its catch rate. The calculator assumes only one active status.
