Pokémon Catch Rate Calculator Gen 7

Accurately determine your chances of catching any Pokémon in Generation 7 games!

Calculator Inputs

A Pokémon catch rate calculator for Gen 7 is a specialized tool designed to estimate the probability of successfully capturing a wild Pokémon in the Generation 7 games: Pokémon Sun, Pokémon Moon, Pokémon Ultra Sun, and Pokémon Ultra Moon. Unlike earlier generations, Gen 7 introduced specific mechanics and multipliers that affect catch rates, making precise calculation essential for trainers aiming to complete their Pokédex, hunt for shiny variants, or simply catch that elusive Pokémon.

This calculator helps players understand how different elements – the Pokémon's health, status conditions, the type of Poké Ball used, and even in-game bonuses like the Catch Charm – interact to determine your chances. It takes the guesswork out of catching, allowing for more strategic gameplay. Whether you're a seasoned veteran or new to the Alola region, this tool provides valuable insights into the game's mechanics.

Why Use a Gen 7 Specific Calculator?

Each generation of Pokémon games has its own unique formulas and values that govern catch rates. Generation 7, for instance, introduced significant changes and features that directly impact how likely you are to catch a Pokémon. These include:

• SOS Battles: The chain-catching mechanic in Sun and Moon, and its enhancements in Ultra Sun and Ultra Moon, can provide substantial bonuses to catch rates.
• Catch Charm: A reward for completing the National Pokédex, offering a permanent boost to catch rates across all games.
• Ball Effectiveness: While many balls function similarly, some have enhanced effectiveness in specific situations (e.g., Dive Balls underwater, Net Balls for Water/Bug types).
• Shiny Pokémon: Gen 7 specifically doubles the catch rate modifier for shiny Pokémon.

Using a calculator that doesn't account for these Gen 7-specific factors will lead to inaccurate predictions. A dedicated Gen 7 Pokémon catch rate calculator ensures you're working with the correct multipliers and formulas.

Pokémon Catch Rate Formula and Explanation (Gen 7)

The core catch rate formula in Generation 7 can be broken down into several components. The general idea is to calculate a "modified catch rate" that is then compared against a random number. The higher the modified catch rate relative to the random number, the higher your success probability.

The primary calculation is:

Catch Rate = (((3 * MaxHP – 2 * CurrentHP) * BaseCatchRate * BallModifier * ShinyModifier * LevelModifier) / (3 * MaxHP)) * StatusModifier * CatchCharmModifier * EncounterModifier

Then, this value is further processed for the actual ball shake sequence. A simplified representation of the final catch percentage is often derived from this "A" value:

Final Catch Percentage ≈ (A / 65535) * 100%

Let's break down the variables used in our calculator:

Catch Rate Variables and Their Meanings (Gen 7)

Variable	Meaning	Unit/Type	Typical Range
Level	The wild Pokémon's current level.	Unitless (Factor)	1 – 100
Base Catch Rate	The Pokémon's inherent difficulty to catch.	0 – 255	0 – 255
Current HP	The wild Pokémon's remaining HP.	HP Points	0 – Max HP
Max HP	The wild Pokémon's maximum HP.	HP Points	1+
Ball Modifier	Effectiveness multiplier of the Poké Ball used.	Multiplier	0.5x to 5x (depending on ball and situation)
Status Modifier	Multiplier based on the wild Pokémon's status condition.	Multiplier	1x (None), 1.5x (Sleep/Freeze), 2x (Poison/Burn/Paralysis)
Shiny Modifier	Multiplier for shiny Pokémon.	Multiplier	1x (Normal), 2x (Shiny)
Catch Charm Modifier	Multiplier from owning the Catch Charm.	Multiplier	1x (No Charm), 1.2x (With Charm)
Encounter Modifier	Bonus from specific encounter mechanics (SOS, DexNav).	Multiplier	1x (None) to 3x (SOS Chain)

Practical Examples

Let's illustrate with some realistic scenarios:

Example 1: Catching a Standard Pokémon

You encounter a Level 30 Gyarados with a Base Catch Rate of 45. It has 150 HP remaining out of a max of 200. It has no status condition. You are using a Great Ball (modifier 1.0x), and you do not have the Catch Charm.

• Inputs:
• Pokémon Level: 30
• Base Catch Rate: 45
• Current HP: 150
• Max HP: 200
• Status Condition: None (1.0x)
• Ball Used: Great Ball (1.0x)
• Shiny Pokémon: No (1.0x)
• Catch Charm: No (1.0x)
• Encounter Bonus: None (1.0x)

Using the calculator, you would find:

• Catch Percentage: Approximately 25.7%
• Formula Result (A): ~16821
• HP Factor (B): ~0.375
• Status Factor (C): 1.0

This indicates a moderate chance, suggesting you might need a few tries or consider weakening it further.

Example 2: Catching a Difficult Pokémon with Bonuses

You're hunting for a shiny Level 50 Ditto with a Base Catch Rate of 35. It's at 50 HP out of a max of 150. It's paralyzed (status modifier 2.0x). You're using a Repeat Ball (3.0x modifier, assuming you've caught Ditto before), and you have the Catch Charm (1.2x modifier). The Ditto has called for help and is part of an SOS chain of 25+ (3.0x encounter bonus).

• Inputs:
• Pokémon Level: 50
• Base Catch Rate: 35
• Current HP: 50
• Max HP: 150
• Status Condition: Paralysis (2.0x)
• Ball Used: Repeat Ball (3.0x)
• Shiny Pokémon: Yes (2.0x)
• Catch Charm: Yes (1.2x)
• Encounter Bonus: SOS Chain 25+ (3.0x)

Inputting these values into the calculator yields:

• Catch Percentage: Approximately 92.7%
• Formula Result (A): ~60761
• HP Factor (B): ~0.667
• Status Factor (C): 2.0

The combination of a shiny Pokémon, low HP, paralysis, a powerful ball, the Catch Charm, and the SOS chain bonus dramatically increases your catch probability, making this a much more favorable encounter.

The status conditions are clearly defined in the dropdown.

Key Factors That Affect Catch Rate in Gen 7

Several elements significantly influence your success when trying to catch a Pokémon in Generation 7:

1. Base Catch Rate: This is fundamental, inherent to each species. Legendaries and pseudo-legendaries typically have very low base rates (e.g., 3), while common Pokémon might have rates of 190 or higher.
2. Pokémon's Current HP: The lower the HP, the higher the catch modifier. This is why weakening the Pokémon is crucial. A Pokémon at 1 HP provides a much larger modifier than one at half health.
3. Status Conditions: Inflicting Sleep or Freeze provides a 1.5x modifier, while Poison, Burn, or Paralysis offer a 2.0x modifier. These significantly increase your chances.
4. Poké Ball Type: Standard balls offer a 1.0x modifier. Specialized balls like Net Balls (3.0x for Water/Bug), Dive Balls (3.5x when fishing/underwater), Repeat Balls (3.5x if you've caught it before), and Timer Balls (up to 4.0x after 30+ turns) can be far more effective in the right situations. Master Balls have a 255x modifier, guaranteeing a catch.
5. Shiny Status: In Gen 7, shiny Pokémon have a doubled catch rate modifier (2.0x), making them easier to catch than their normal-colored counterparts.
6. Catch Charm: This post-game item provides a consistent 1.2x multiplier to all catch attempts, a valuable boost for dedicated trainers.
7. SOS Battle Chaining: Successfully chaining encounters in SOS battles provides escalating bonuses. A chain of 20-30 or more can grant a 2.0x or 3.0x multiplier, respectively, significantly improving catch rates.
8. Level: While the formula shows level as a factor, its direct impact in Gen 7's simplified calculation is minimal compared to HP, status, and ball modifiers. It mainly influences the base "A" value.

FAQ: Pokémon Catch Rate Calculator (Gen 7)

Q1: What is the difference between this calculator and a general Pokémon catch rate calculator?

This calculator is specifically tuned for Generation 7 (Sun, Moon, Ultra Sun, Ultra Moon) mechanics, including bonuses like the Catch Charm and specific modifiers for SOS battles and shiny Pokémon that may differ in other generations.

Q2: How accurate is the catch percentage?

The percentage is highly accurate based on the known formulas for Generation 7. However, it represents the probability *before* the ball shakes. The actual catch involves a random number generation against this calculated value, meaning a 90% chance doesn't guarantee a catch every single time.

Q3: My calculated percentage is low. What can I do?

To improve your chances: weaken the Pokémon further (get its HP as low as possible), inflict a status condition (Sleep/Freeze or Poison/Burn/Paralysis), use a more effective Poké Ball for the situation (e.g., Dive Ball underwater, Repeat Ball for multiples), try to chain SOS battles for bonuses, or ensure you have the Catch Charm.

Q4: What does the "Formula Result (A)" mean?

This is an intermediate value calculated directly from the main formula. It's the number the game compares against a random number (out of 65535) to determine if the ball shakes successfully. A higher "A" value means a better chance.

Q5: Which status condition gives the biggest boost?

Sleep and Freeze provide a 1.5x multiplier, while Poison, Burn, and Paralysis provide a 2.0x multiplier. Therefore, Poison, Burn, or Paralysis offer a greater boost.

Q6: Do specific balls like the Net Ball or Dive Ball always work best?

Not always. Their effectiveness is situational. Net Balls are best for Water and Bug-type Pokémon. Dive Balls are best when fishing or underwater. Repeat Balls are best if you have already encountered that Pokémon species before. Timer Balls improve significantly after many turns. Always check the conditions.

Q7: Does the Pokémon's level really matter in Gen 7?

While level is part of the formula, its direct impact in Gen 7 is less significant compared to other factors like HP, status, and ball type. The formula is designed to make these other elements more dominant.

Q8: How is the Catch Charm obtained?

The Catch Charm is awarded by Professor Kukui in Konikoni City after you have successfully registered all 810 Pokémon in your National Pokédex across your save file. It provides a permanent 1.2x boost to your catch rate.
