Poké Ball Catch Rate Calculator
This calculator helps you estimate the probability of successfully catching a Pokémon in battle. The catch rate depends on several factors, including the Pokémon's base catch rate, its current HP, status effects, and the type of Poké Ball used. The formula used here is a simplified representation of the actual game mechanics.
Pokémon's Base Catch Rate:
Current HP:
Maximum HP:
Status Effect:
None
Sleep/Freeze
Poison/Burn/Paralysis
Poké Ball Modifier:
Calculate Catch Rate
function calculateCatchRate() {
var baseCatchRate = parseFloat(document.getElementById("pokemonBaseCatchRate").value);
var currentHP = parseFloat(document.getElementById("currentHP").value);
var maxHP = parseFloat(document.getElementById("maxHP").value);
var statusEffect = parseInt(document.getElementById("statusEffect").value);
var ballModifier = parseFloat(document.getElementById("ballModifier").value);
var resultElement = document.getElementById("result");
if (isNaN(baseCatchRate) || isNaN(currentHP) || isNaN(maxHP) || isNaN(ballModifier) ||
baseCatchRate 255 || currentHP < 1 || maxHP < 1 || ballModifier maxHP) {
resultElement.innerHTML = "Current HP cannot be greater than Maximum HP.";
return;
}
var hpRatio = maxHP > 0 ? Math.floor( ( (3 * maxHP) – (2 * currentHP) ) * 255 / (3 * maxHP) ) : 0;
if (hpRatio 255) hpRatio = 255;
var catchRate = Math.floor( ( ( ( (baseCatchRate * hpRatio) / 255 ) * statusEffect ) * ballModifier ) );
if (catchRate > 255) catchRate = 255;
var catchProbability = (catchRate / 255) * 100;
resultElement.innerHTML = "Estimated Catch Probability: " + catchProbability.toFixed(2) + "%";
