What the calculation does
Available Cash = max(0, balance − reserve). Purchases at this price = floor(available Cash ÷ entered price). This is budget arithmetic, not a shop quote.
Enter your cash balance, the purchase price currently shown in game and a reserve you want to keep. Use one planned purchase when prices change after upgrades; the tool performs arithmetic and does not forecast the next price.
Use the price offered by your current client. Additional-slot prices can change between stages, so do not multiply one displayed price into an assumed full upgrade table.
Your inputs stay in the calculator in your browser. A calculated budget does not purchase anything or predict changing shop prices.
Available Cash = max(0, balance − reserve). Purchases at this price = floor(available Cash ÷ entered price). This is budget arithmetic, not a shop quote.
For an active slot, enter the price currently offered and keep the target at one. Recalculate after a purchase instead of assuming later slots cost the same.
Decide whether your next goal is active capacity or a tool. The calculator can check the budget once you have chosen a real cash price; it does not rank pets or equipment.
Use the current Cash price of the purchase you are considering. Do not mix a Robux price with an in-game Cash balance.
No. Enter the currently displayed price and calculate one planned purchase. Recalculate if a later offer changes.
A reserve is your own spending choice. It keeps part of the entered balance outside this purchase budget rather than assuming you want to spend everything.
No. It only calculates from your inputs and does not connect to your Roblox account or make purchases.
