Catch Rate Sensitivity Analysis

How catch rate changes with key factors.

What is the Let's Go Catch Rate?

In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, catching Pokémon is a core mechanic. Unlike traditional RPGs where you battle Pokémon to weaken them before catching, Let's Go simplifies this by removing wild battles. Instead, you aim to land successful throws with various Poké Balls, while mitigating the Pokémon's attempts to escape or attack. The "Catch Rate" is a crucial underlying statistic that determines your probability of successfully capturing a Pokémon with a single throw. Understanding this rate, and the factors that influence it, is key to efficient and successful Pokémon collection.

This calculator is designed for players of Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! who want to precisely understand their chances of catching a specific Pokémon. It's particularly useful for:

• Players aiming to complete their Pokédex efficiently.
• Trainers focusing on catching Pokémon with specific IVs or shiny variants.
• Anyone curious about the underlying mechanics of the game.

Common misunderstandings often revolve around how multipliers stack, the impact of status conditions, and the significant bonus provided by catch combos. This calculator aims to demystify these elements.

Let's Go Catch Rate Formula and Explanation

The catch rate in Pokémon Let's Go is determined by a complex formula that combines the Pokémon's inherent difficulty with several situational multipliers. The core idea is to calculate an overall "catch multiplier" which is then applied to the Pokémon's base catch rate to determine the final chance of success.

The Formula:

Effective Catch Rate (%) = [ (Base Catch Rate * Catch Rate Multiplier) / 255 ] * 100

Where the Catch Rate Multiplier is the product of all individual multipliers:

Catch Rate Multiplier = (Ball Multiplier) * (Status Multiplier) * (Combo Multiplier) * (Throw Multiplier) * (Frenzy Plant Multiplier)

Variables Table:

Variables Used in Catch Rate Calculation

Variable	Meaning	Unit	Typical Range
Base Catch Rate	The Pokémon's inherent difficulty to catch.	Unitless (0-255)	1 – 255
Level	Your Pokémon's current level. Crucial for determining flee chance and sometimes used in complex calculations in other games, but primarily influences flee chance here. (Note: This calculator focuses on capture probability itself, not flee mechanics).	Level (1-100)	1 – 100
Ball Multiplier	A bonus provided by the type of Poké Ball used.	Multiplier (e.g., 1.0, 1.5, 2.0)	1.0 (Standard), 1.5 (Great), 2.0 (Ultra), 2.55 (Master)
Status Multiplier	A bonus based on the status condition of the wild Pokémon.	Multiplier (e.g., 1.0, 2.0, 2.5)	1.0 (None), 2.0 (Sleep/Freeze), 2.5 (Burn/Poison/Paralysis)
Combo Multiplier	A significant bonus for chaining catches of the same species.	Multiplier (e.g., 1.0, 1.1, 1.2, 1.3, etc.)	1.0 (0-1 combo) up to ~1.5+ (high combos)
Throw Multiplier	A bonus based on the accuracy and type of your throw.	Multiplier (e.g., 1.0, 1.5, 2.0, 2.5)	1.0 (Regular), 1.5 (Nice/Curveball), 2.0 (Great), 2.5 (Excellent)
Frenzy Plant Multiplier	A small bonus applied if certain powerful moves were used prior.	Multiplier (1.0 or 1.5)	1.0 (No), 1.5 (Yes)
Effective Catch Rate	The final calculated probability of catching the Pokémon.	Percentage (0-100%)	0% – 100%

Practical Examples

Let's illustrate with a couple of scenarios:

Example 1: Catching a Common Pokémon

Scenario: You're trying to catch a Pidgey at Level 5. You have a decent catch combo of 10 (yielding a small multiplier). You use a Great Ball, land a Nice Throw, and the Pidgey has no status condition.

• Pokémon Species: Pidgey
• Base Catch Rate: 255
• Level: 5
• Status Condition: None (Multiplier = 1.0)
• Ball Type: Great Ball (Multiplier = 1.5)
• Catch Combo: 10 (Approx. Combo Multiplier = 1.2)
• Throw Type: Nice Throw (Multiplier = 1.5)
• Frenzy Plant: No (Multiplier = 1.0)

Calculation:

Catch Rate Multiplier = 1.5 (Ball) * 1.0 (Status) * 1.2 (Combo) * 1.5 (Throw) * 1.0 (Frenzy) = 2.7

Effective Catch Rate = [ (255 * 2.7) / 255 ] * 100 = 270%

Result: With these conditions, your effective catch rate is 270%. Since the maximum effective rate capped at 255 for calculation purposes before being divided by 255, this results in a 100% catch chance with the Great Ball. Even with a standard Poké Ball (1.0x multiplier), the rate would be [ (255 * 1.8) / 255 ] * 100 = 180%, still a 100% catch chance.

Example 2: Catching a Rarer Pokémon

Scenario: You encounter a Chansey at Level 30. You want to maximize your chances. You use an Ultra Ball, land an Excellent Throw, and have a high catch combo of 50. Chansey is Paralyzed.

• Pokémon Species: Chansey
• Base Catch Rate: 45
• Level: 30
• Status Condition: Paralysis (Multiplier = 2.5)
• Ball Type: Ultra Ball (Multiplier = 2.0)
• Catch Combo: 50 (Approx. Combo Multiplier = 1.4)
• Throw Type: Excellent Throw (Multiplier = 2.5)
• Frenzy Plant: Yes (Multiplier = 1.5)

Calculation:

Catch Rate Multiplier = 2.0 (Ball) * 2.5 (Status) * 1.4 (Combo) * 2.5 (Throw) * 1.5 (Frenzy) = 17.5

Effective Catch Rate = [ (45 * 17.5) / 255 ] * 100 = [ 787.5 / 255 ] * 100 ≈ 308.8%

Result: The effective catch rate is approximately 308.8%. Divided by 255, this gives a multiplied rate of ~1.21. With the Ultra Ball, your final catch chance calculation would be approximately 1.21 * 2.0 = 2.42, which gets capped. The effective rate calculation here might seem confusingly high, but it indicates a very strong probability. Let's recalculate the final percentage: the formula simplifies to `(Base Catch Rate * Total Multiplier) / 255`. So, `(45 * 17.5) / 255 * 100 = 308.8%`. This extremely high value, when compared to the base 45/255 (~17.6% chance), signifies a near-certain capture with the Ultra Ball, given the excellent throw, status, and combo.

Key Factors That Affect Let's Go Catch Rate

Several elements significantly influence your likelihood of capturing a Pokémon in Let's Go:

1. Base Catch Rate: This is the fundamental value for each Pokémon species. Rarer and stronger Pokémon inherently have lower base catch rates, making them harder to catch.
2. Ball Type: Higher-tier balls (Great, Ultra) provide substantial multipliers, significantly increasing your odds compared to the basic Poké Ball. The Master Ball offers an automatic capture.
3. Catch Combo: This is arguably the most powerful tool for increasing catch rates in Let's Go. Chaining consecutive catches of the same species dramatically boosts the catch multiplier, making even rare Pokémon easier to catch as your combo grows.
4. Throw Accuracy (Nice, Great, Excellent): Landing more precise throws provides a direct multiplier bonus. Mastering Excellent Throws can drastically improve your chances, especially when combined with a high combo.
5. Status Conditions: Inflicting Sleep or Freeze provides the largest multiplier boost among status effects, followed by Burn, Poison, or Paralysis. This makes it strategic to put a Pokémon to sleep before attempting a catch.
6. Frenzy Plant / Similar Moves: Using powerful charged moves before attempting a catch provides a moderate boost, further tipping the odds in your favor.
7. Partner Pokémon Bonuses: Using the special partner moves (Snorlax's Blessing, Eevee's Charm, Pikachu's Charm) grants a multiplier equivalent to a Great Ball, aiding in captures.

FAQ about Let's Go Catch Rate

• What is the highest possible base catch rate? The highest base catch rate in Pokémon Let's Go is 255, shared by many common Pokémon like Rattata, Pidgey, and Caterpie.
• What is the lowest possible base catch rate? The lowest base catch rate belongs to legendary Pokémon like Mewtwo, which has a base catch rate of 3.
• Does the level of MY Pokémon matter for catching? In Let's Go, the level of your Pokémon does not directly affect the catch rate calculation. However, it can influence flee rates in some indirect ways and is often correlated with the level of wild Pokémon you encounter.
• How much does a catch combo actually increase the rate? The increase is gradual. A combo of 10 provides a noticeable boost, while a combo of 31+ offers the maximum multiplier bonus available from combos, significantly improving your chances. The calculator precisely quantifies this.
• Is it better to use a Great Ball or inflict Sleep/Freeze? Both offer significant bonuses. A Great Ball multiplies the rate by 1.5x, while Sleep/Freeze multiplies it by 2.0x. Combining both is ideal for maximizing your odds on difficult targets.
• Can the catch rate exceed 100%? Yes, the *effective* catch rate can exceed 100% (or rather, the calculated value before dividing by 255 can be very high). This simply means your chance of capturing the Pokémon is extremely high, often effectively 100% with the ball you've chosen. The game likely caps the final probability at 100%.
• Do Partner Pokémon bonuses stack with other balls? Partner Pokémon bonuses (like Pikachu's Charm) provide a multiplier equivalent to a Great Ball (1.5x). This multiplier will stack with other bonuses like throw type and status conditions.
• Does the calculation change for Shiny Pokémon? No, the underlying catch rate calculation remains the same for Shiny Pokémon. Your chances of encountering a Shiny are separate from the mechanics of catching once encountered.
