The calculation
Spendable = max(0, balance − reserve). Affordable attempts = floor(spendable ÷ attempt price). Keep one currency throughout.

Enter one currency balance, the attempt price shown by your machine and a reserve. Calculate how many attempts fit before you spend; the result does not predict a ball or a rarity.

Machine attempt budget
Enter a non-negative budget and a cost greater than zero. The cost should come from the live game panel.
Calculation stays in your browser. No Roblox login or odds prediction is used.
Use the displayed offer
Read the unit price from the machine you intend to use. The Gem Machine uses Gems; do not combine that balance with a Coins total.
Attempts are not guaranteed results
An affordable attempt count does not promise a named ball. Pool restrictions and displayed probabilities are different information.
Budget questions
What does this calculator work out?
It calculates affordable attempts, remaining spendable currency and any shortfall from the values you enter.
Does it predict the next ball?
No. It performs budget arithmetic and does not assume a probability, pity rule or guaranteed reward.
Can I add Coins and Gems together?
No. Use one currency balance and a price in that same currency for each calculation.
Does it need my Roblox account?
No. The arithmetic runs in your browser without a Roblox login.
