How the calculation works
Subtract the reserve from the balance, with zero as the minimum. Divide that spendable amount by the unit price and round down to a whole number of purchases.

Plan a purchase batch
Use one currency and one unit price throughout. Read the cost from the selected purchase panel in your own game.
Your purchase plan
Pet packs budget
Enter a non-negative balance and a unit price greater than zero. Keep the balance, price and reserve in the same currency.
These inputs stay in your browser. The tool calculates spending; it does not predict which pets a pack reveals.
Read the selected price
Use the price displayed for the pack or merchandise box you plan to buy. A regular Fish Pack and a Robux pack use different currencies, so calculate them separately.
Use one price per batch
The result assumes every purchase in the batch costs the entered amount. For differently priced items or successive expansions, calculate separate batches. Pack outcomes are not part of this calculation.
Purchase calculator questions
What does the Pet Store Tycoon calculator calculate?
It calculates the number of equal-price purchases that fit your balance after keeping a reserve, the remaining money and any shortfall for a target batch.
Can I calculate both cash and Robux purchases?
Yes, in separate calculations. Use the same currency for the balance, price and reserve each time; the tool does not convert cash into Robux.
Will it predict which animal a pack reveals?
No. It uses the price you enter to calculate a spending limit. It does not include pack probabilities or a guaranteed rare-pet result.
Are my balance and price uploaded?
The calculator performs these calculations in your browser. It has no Roblox account connection and does not submit its input values.
