Measure one normal kick
Use the same Ball, Legend, friend count, and Premium state for the sample and the estimate.
Enter your current amount, target purchase price, and the reward you observed from one comparable kick. The calculator estimates repetitions; it does not claim an official cash formula.
Enter the resource you have, your target, and a player-observed reward per run. The result is an estimate and does not invent an official drop rate.
Use the same Ball, Legend, friend count, and Premium state for the sample and the estimate.
A better Ball or Legend can change the reward per kick, so replace the sample instead of trusting an old result.
The estimate assumes similar rewards per kick. It cannot predict a new Sky, bonus, or server-side balance change.
