Minecraft Fishing Calculator

Calculate fish, junk, and treasure odds, Lure timing, expected attempts, and seeded catch simulations.

Quick answer

How the Fishing Calculator Works

Set Luck of the Sea, Lure, and water/sky conditions. The calculator separates category probability from individual loot and shows how conditions change timing and treasure eligibility.

How to Use the Minecraft Fishing Calculator

Choose Luck of the Sea and Lure levels.
Set biome, open-water, and sky conditions to match the fishing location.
Read exact probabilities or run a seeded cast sample.

Important Minecraft Mechanics

Luck of the Sea lowers junk weight and raises treasure weight before the category weights are normalized.

Treasure requires open-water conditions; without them its category weight becomes zero.

Edition and Version Notes

Java Edition loot mechanics. Use the version selector when the tool provides one. GamerCubic does not label Java-only data or commands as Bedrock-compatible.

Calculations, uploaded files, generated plans, and normal exports are processed locally unless a control clearly requests an online username or profile lookup.

Fishing Calculator FAQs

Does Lure improve treasure odds?

No. Lure changes wait timing; Luck of the Sea changes the category weights.

Why is treasure shown as zero?

Current Java treasure loot requires a valid open-water position.
