Pokémon Catch Rate Calculator
It is a stressful experience, catching a legendary Pokémon or a rare shiny. Each Ultra Ball that is thrown is a gamble. Our Pokemon Catch Rate Calculator aims to remove the luck factor in the game and give you accurate probabilities in the game that is mathematical, according to the official gameplay of Generation 2 up to Generation 5.
What is a Pokemon Catch rate Calculator?
A Pokémon catch rate calculator is an app that is based on simulating the inner mechanics of the Pokémon games. Each Pokemon has an unknown Base Capture Rate (Bulbasaur has a 45, and Mewtwo has a 3). What this tool does is to multiply that rate with the current scenario- so how much the Pokémon has left to live and the Poké Ball you are using so that you get to know the exact percentage chance that you have on succeeding in that throw.

The calculator then works with the official Capture Value (a) formula which is in the code of the game. To the contemporary generations, the formula is:

After the value of a is known, shake checks are done in the game. When the value of a is 255 and above, the catch is ensured. We have this complicated backend into a simple percentage that can be understood by players to translate this complex backend logic.
Instructional Manual to Calculator usage.
- Select Generation: Select the version of the game that you are playing (Gen 2, 3/4, or 5).
- Name Pokémon: Type the name of the Pokémon that you are attempting to catch. The tool is going to fetch its base catch rate automatically.
- Customize HP: Slider will adjust the current health bar of the Pokémon in the game.
- Poke Ball: Select the ball that you are using. The multipliers of different balls (Level Ball or Heavy Ball) are different.
- Apply Status: When a Pokémon is asleep, frozen or paralyzed, it can have a status applied to it, which is displayed as increasing your chance of winning.
- Read Results: With the option of Auto-Calculate, the opportunity will be displayed automatically.
Pricing Explained Pokemon Catch Rate Calculator.
Our calculator is 100% free to use. We do not offer the premium gaming guides like some of our competitors do, but we do give the player access to the entire database of Pokémon capture rates and all the exclusive Poké Ball multipliers at no cost to the player.
Example Calculation
Suppose that you are battling a Bulbasaur (Base rate: 45) with 100HP on a regular Poké Ball:
- HP Factor: When the health is at full the multiplier is approximately 1/3.
- Math: $45 \times 1 \div 3 = 15$.Result: $15 \div 240 = 0.0625$.
- Percentage: 6.25% chance per ball.
Your odds increase to more than a quarter in case you reduce that Bulbasaur to 1 HP and place it in the Sleep.
