Transparent formula
Spendable equals the larger of zero or balance minus reserve. Affordable actions equal spendable divided by current cost, rounded down.
Keep the Door Locked Cost Calculator
Enter the balance and cost shown in your current server. The calculator protects a reserve and reports how many equal-cost actions fit. It does not identify the currency, predict visitor outcomes, value Kindness, or assume that the observed pizza price remains current.

Current server values
Protect a survival reserve
Copy the current numeric cost from the live interface. Leave it blank when the label or amount is unclear instead of treating an archived observation as permanent.
Calculated locally
Sanity food budget
Enter a non-negative balance and a current cost greater than zero.
No Roblox login is used. The calculation stays in your browser and depends entirely on the values you enter.
Why cost starts blank
The archive observes 150 for pizza and a visitor request, but it does not prove a permanent currency label or price. Read the current screen.
What the tool cannot decide
It cannot judge a visitor, restore sanity, predict an ending, prove a hidden reward, or tell you whether spending is the best choice.
