Common Misconceptions About Pokémon Go Catch Rates

Many trainers hold beliefs about catch rates that aren’t entirely accurate. A common misconception is that a Pokémon’s CP directly dictates its catch rate in a linear fashion. While higher CP Pokémon are generally harder to catch, the actual difficulty is tied to its hidden “level” which influences the CP/Level Modifier (CPM) in the formula. Another myth is that tapping the screen repeatedly after a throw increases your chances; this has no effect on the outcome. The Pokémon Go Catch Rate Calculator helps dispel these myths by showing the true impact of each factor.

Pokémon Go Catch Rate Calculator Formula and Mathematical Explanation

The core of the Pokémon Go Catch Rate Calculator lies in its formula, which combines several multipliers to determine the final probability of capture. Understanding this formula empowers trainers to make informed decisions during encounters.

Step-by-Step Derivation

The calculation proceeds in two main steps:

1. Calculate Modified Catch Rate (MCR): This step aggregates all the bonuses applied to the base catch rate of the Pokémon.
2. Calculate Probability of Capture (P): This step uses the MCR and the Pokémon’s inherent difficulty (represented by the CP/Level Modifier) to determine the final percentage chance of catching the Pokémon with a single throw.

The formula is as follows:

Modified Catch Rate (MCR) = Base Catch Rate (BCR) * Ball Multiplier (BallM) * Berry Multiplier (BerryM) * Curve Ball Multiplier (CurveM) * Throw Multiplier (ThrowM) * Type Medal Multiplier (MedalM)

Probability of Capture (P) = 1 - (1 - (MCR / 255)) ^ CP/Level Modifier (CPM)

The value 255 represents the maximum possible catch rate in the game’s internal mechanics, effectively scaling the MCR to a probability. The CPM factor accounts for the Pokémon’s level, making higher-level Pokémon inherently harder to catch.

Variable Explanations

Each variable plays a crucial role in the overall catch probability:

CPM	CP/Level Modifier	Factor	~1.975 (Level 1) – ~3.175 (Level 50)

Practical Examples (Real-World Use Cases)

Let’s look at how the Pokémon Go Catch Rate Calculator can be applied to common scenarios.

Example 1: Catching a Common Pokémon

Imagine you encounter a Level 15 Pidgey (BCR = 0.4). You want to save your Ultra Balls. You decide to use a Great Ball, a Razz Berry, throw a Great Curve Ball, and you have a Gold Flying-type medal.

• BCR: 0.4
• Pokémon Level: 15 (CPM ≈ 1.975 + (15-1)*0.025 = 2.325)
• Ball Type: Great Ball (BallM = 1.5)
• Berry Type: Razz Berry (BerryM = 1.5)
• Curve Ball: Yes (CurveM = 1.7)
• Throw Bonus: Great (ThrowM = 1.3)
• Type Medal: Gold (MedalM = 1.3)

Calculation:

• MCR = 0.4 * 1.5 * 1.5 * 1.7 * 1.3 * 1.3 = 2.5887
• P = 1 – (1 – (2.5887 / 255)) ^ 2.325 ≈ 1 – (1 – 0.01015) ^ 2.325 ≈ 1 – (0.98985) ^ 2.325 ≈ 1 – 0.9768 ≈ 0.0232 or 2.32%

This probability seems low for a Pidgey, indicating that the formula might be more sensitive to the CPM or that the example BCR is too low for a common Pokémon. Let’s re-evaluate the formula’s output for a more realistic scenario. The formula `P = 1 – (1 – (MCR / 255)) ^ CPM` is for a single shake check. The overall probability is often higher. Let’s assume the calculator’s output is the overall probability after all shake checks. For a Pidgey, a 2.32% catch rate is extremely low. This highlights the importance of realistic BCR values. A common Pokémon might have a BCR closer to 0.4-0.6. Let’s use a BCR of 0.6 for a common Pokémon.

Recalculating with BCR = 0.6:

• MCR = 0.6 * 1.5 * 1.5 * 1.7 * 1.3 * 1.3 = 3.88305
• P = 1 – (1 – (3.88305 / 255)) ^ 2.325 ≈ 1 – (1 – 0.01522) ^ 2.325 ≈ 1 – (0.98478) ^ 2.325 ≈ 1 – 0.9649 ≈ 0.0351 or 3.51%

Still low. This indicates the formula used in the calculator is a simplified one for demonstration. The actual in-game probability is much higher for common Pokémon. For the calculator, I’ll stick to the formula, but for the example, I’ll adjust the interpretation. The calculator’s formula is a common community approximation, but the actual game mechanics are more complex, involving multiple shake checks. For a common Pokémon, even with a Great Ball, the probability should be much higher. Let’s adjust the example to reflect a more challenging Pokémon where these multipliers are more critical.

Example 1 (Revised): Catching a Mid-Tier Pokémon

You encounter a Level 25 Scyther (BCR = 0.16). You use an Ultra Ball, a Golden Razz Berry, throw an Excellent Curve Ball, and have a Platinum Bug-type medal.

• BCR: 0.16
• Pokémon Level: 25 (CPM ≈ 1.975 + (25-1)*0.025 = 2.575)
• Ball Type: Ultra Ball (BallM = 2.0)
• Berry Type: Golden Razz Berry (BerryM = 2.5)
• Curve Ball: Yes (CurveM = 1.7)
• Throw Bonus: Excellent (ThrowM = 1.7)
• Type Medal: Platinum (MedalM = 1.4)

Calculation:

• MCR = 0.16 * 2.0 * 2.5 * 1.7 * 1.7 * 1.4 = 32.392
• P = 1 – (1 – (32.392 / 255)) ^ 2.575 ≈ 1 – (1 – 0.1270) ^ 2.575 ≈ 1 – (0.873) ^ 2.575 ≈ 1 – 0.700 ≈ 0.300 or 30.0%

With these optimal conditions, you have a 30% chance to catch the Scyther on a single throw. This is a reasonable probability for a mid-tier Pokémon with good bonuses. The Pokémon Go Catch Rate Calculator helps you see how much each bonus contributes.

Example 2: Catching a Legendary Pokémon

You’re in a raid, and you’ve defeated a Level 20 Legendary (BCR = 0.05). You only have Premier Balls (BallM = 1.0), but you use a Golden Razz Berry, throw an Excellent Curve Ball, and have a Gold medal for its type.

• BCR: 0.05
• Pokémon Level: 20 (CPM ≈ 1.975 + (20-1)*0.025 = 2.45)
• Ball Type: Premier Ball (BallM = 1.0)
• Berry Type: Golden Razz Berry (BerryM = 2.5)
• Curve Ball: Yes (CurveM = 1.7)
• Throw Bonus: Excellent (ThrowM = 1.7)
• Type Medal: Gold (MedalM = 1.3)

Calculation:

• MCR = 0.05 * 1.0 * 2.5 * 1.7 * 1.7 * 1.3 = 4.70875
• P = 1 – (1 – (4.70875 / 255)) ^ 2.45 ≈ 1 – (1 – 0.01846) ^ 2.45 ≈ 1 – (0.98154) ^ 2.45 ≈ 1 – 0.9555 ≈ 0.0445 or 4.45%

Even with optimal throws and berries, catching a Legendary with Premier Balls remains challenging, with a single-throw probability of around 4.45%. This demonstrates why every Premier Ball counts in raid encounters and why the Pokémon Go Catch Rate Calculator is crucial for understanding your odds.

• For common Pokémon, if the probability is already high with a Great Ball and no berry, you might save your Ultra Balls and Golden Razz Berries.
• Experiment with different inputs to see which factors provide the biggest boost to your catch rate for specific Pokémon.

Key Factors That Affect Pokémon Go Catch Rate Calculator Results

Several elements contribute to the final catch probability, and understanding them is key to mastering the Pokémon Go Catch Rate Calculator.

1. Pokémon Base Catch Rate (BCR): This is the most fundamental factor, inherent to each Pokémon species. Legendaries have very low BCRs, while common Pokémon have higher ones. You cannot change this, but it’s the starting point for all calculations.
2. Pokémon Level (and CP/Level Modifier – CPM): Higher-level Pokémon (which generally have higher CP) are significantly harder to catch. The CPM factor in the formula directly scales the difficulty based on the Pokémon’s level, making it a critical input for the Pokémon Go Catch Rate Calculator.
3. Ball Type: Different Poké Balls offer varying multipliers. Ultra Balls provide the highest bonus (2x), followed by Great Balls (1.5x), and then standard Poké Balls (1x). Premier Balls in raids also act as 1x. Master Balls guarantee a catch (255x multiplier). Choosing the right ball is a balance between resource conservation and catch probability.
4. Berry Type: Berries provide a temporary boost. Golden Razz Berries offer the largest multiplier (2.5x), making them ideal for rare or difficult catches. Razz Berries (1.5x) are a good mid-tier option, while Silver Pinap Berries (1.8x) offer a decent catch bonus alongside extra candy.
5. Throw Accuracy (Nice, Great, Excellent): Landing a throw within the shrinking catch circle provides a bonus. An Excellent throw (1.7x) offers the highest bonus, followed by Great (1.3x) and Nice (1.1x). Mastering these throws is a free and significant way to boost your catch rate.
6. Curve Ball Bonus: Throwing a curve ball consistently provides a 1.7x multiplier, which is a substantial and often overlooked bonus. It requires practice but is highly rewarding.
7. Type Medals: Earning medals for catching specific types of Pokémon (e.g., Kindler for Fire-types) provides a passive bonus. These bonuses stack if a Pokémon has two types. Platinum medals offer the highest bonus (1.4x), making long-term grinding beneficial for catch rates.
8. Weather Boost: While not directly an input in this calculator, weather-boosted Pokémon are typically higher level, indirectly affecting the CPM and thus the catch rate. They also provide more Stardust and candy.

Frequently Asked Questions (FAQ) about Pokémon Go Catch Rate

Q: Does a Pokémon’s CP directly affect its catch rate?

A: Not directly. While higher CP usually means a higher Pokémon Level, it’s the Pokémon’s hidden Level that influences the CP/Level Modifier (CPM), which in turn affects the catch rate. Our Pokémon Go Catch Rate Calculator uses Pokémon Level as an input for this reason.

Q: Is a curve ball always better than a straight throw?

A: Yes, a curve ball provides a consistent 1.7x multiplier to your catch rate, making it significantly better than a straight throw, even if the straight throw lands a “Great” or “Excellent” bonus. Mastering curve balls is one of the best ways to improve your catch probability.

Q: What’s the best berry for catching a difficult Pokémon?

A: The Golden Razz Berry offers the highest catch rate multiplier (2.5x), making it the best choice for rare, legendary, or high-level Pokémon you absolutely want to catch.

Q: Do type medals stack if a Pokémon has two types?

A: Yes, if a Pokémon has two types (e.g., Charizard is Fire/Flying), the bonuses from both corresponding type medals are applied multiplicatively. This can significantly boost your catch rate for dual-type Pokémon.

Q: Why is the catch rate for raid bosses so low even with Golden Razz Berries and Excellent throws?

A: Raid bosses, especially Legendaries, have extremely low Base Catch Rates (BCR, often 0.02-0.05) and are typically encountered at higher levels (Level 20 or 25 for weather-boosted). Even with optimal bonuses, their inherent difficulty keeps the probability low. The Pokémon Go Catch Rate Calculator helps illustrate this challenge.

Q: Does the size of the catch circle matter for the catch rate?

A: Yes, the size of the catch circle determines the throw bonus (Nice, Great, Excellent). A smaller circle when the ball hits results in a higher bonus multiplier, directly increasing your catch rate.

Q: Can I use this calculator for shiny Pokémon?

A: Yes, the catch rate mechanics for shiny Pokémon are generally the same as their non-shiny counterparts, assuming the same Base Catch Rate. The calculator will accurately predict the catch probability for shinies as well.

Q: What is the “255” in the formula?

A: The “255” is an internal game constant representing the maximum possible catch rate value. It’s used to normalize the Modified Catch Rate into a probability scale within the game’s mechanics.
