The calculation
Spendable yen is max(0, balance minus reserve). Whole purchases are floor(spendable yen divided by price). The remainder is spendable yen left after those purchases.

Plan the purchase before spending
Use the balance and item price shown in your own game. For different item prices, run a separate calculation rather than treating them as one equal-price purchase.
Budget arithmetic
Equal-price purchases budget
Enter a non-negative yen balance and a purchase price greater than zero.
The calculation runs in your browser. It uses no Roblox login and makes no in-game purchase.
Use one actual price
Food, treatment and outfits can have different costs. Enter the specific displayed price you are considering; this tool does not provide a live shop database.
Choose the reserve yourself
Keep the amount you want for a later city task. The reserve is a budgeting choice, not a game requirement or a promise that one amount covers every injury.
Yen calculation help
What does this calculator return?
Whole equal-price purchases that fit after your reserve, unused spendable yen, and any shortfall for the desired count.
Can I combine different food and treatment prices?
The formula uses one price for every purchase. Calculate different prices separately, or enter the total known cost of one bundle as a single purchase.
Does it read my Roblox balance?
You enter the values yourself. The calculator does not connect to your account or send money.
What if the reserve exceeds my balance?
Spendable yen is clamped to zero. The desired-count check shows the additional amount needed while preserving the entered reserve.
