This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own Pet Store Tycoon session. It will not click the shop.
Upgrade payback
Upgrade payback
Estimate how long a Coin purchase takes to earn back. You type the button price and the extra Coins you expect from each care or sale cycle. The sample numbers are not prices from Pet Store Tycoon.
Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.
Replace every default before you trust the result. The form does not read your Roblox account, and it does not know button prices, which were not published as a fixed list.
