Spawn Calculator

The Spawn Calculator estimates the chance that a single wild spawn near you is a chosen Pokemon, given the biome, location type, time of day, weather and Y-level. Choose a Pokemon and a situation, or use Find best chance to search for the settings with the highest odds.

How it works

Each spawn attempt picks one Pokemon at random from those whose conditions match the location, weighted by spawn rarity. The chance shown is that species' total rarity divided by the total rarity of every Pokemon that can spawn in the same situation. The same calculator appears on each species page under Spawns, pre-filled for that Pokemon.

The Consecutive times setting evaluates a block of consecutive times of day and weights each time by its real in-game length, so longer times (such as Night) count more than short ones (such as Midnight). With Strict block enabled, Find best chance only accepts blocks where the species spawns during every time in the block.

Limitations

The calculator covers standard overworld spawns only. It does not model legendary or boss spawners, contextual rarity multipliers, structure or anticondition gating, or light level. Results reflect relative spawn weighting, not the absolute spawn rate per minute.
