Chance Calculator

Plan a farming session using a rate you can verify in game. This calculator does not claim unknown drop rates are official.

Chance of at least one drop64.15%

At 5% per attempt, the statistical average is one success per 20.0 attempts. An average is not a guarantee.

How the math works

The chance of missing once is 1 − rate. We raise that miss chance to the number of independent attempts, then subtract the result from 1. Real games can use pity systems or changing rates, so treat the answer as a model unless the game confirms every attempt is independent.

Frequently asked questions

Where do I find a rate?

Use an in-game drop panel or a developer announcement. Community estimates should be treated as estimates.

Does 100 average attempts guarantee a 1% drop?

No. Random results can arrive sooner or much later.
