Drop probability

Hatch odds planner

Estimate the chance of at least one success from the percent printed on an egg and the number of hatches you plan. The form does not read your pets or inventory. The starting numbers are examples, not Pet Simulator 99 drop rates. Luck potions are described as skipping exclusive eggs, so do not add a luck bonus unless that egg says the bonus counts.

Enter values from your session.

Chance of at least one success = 1 βˆ’ (1 βˆ’ chance per attempt) raised to the number of attempts.

Replace both defaults with the egg's displayed percent and your planned hatches. 1% and 100 hatches is only a form example. This is an independent-trial estimate of at least one success, not a pity timer.
