Transparent formula
Spendable cash is max(0, budget minus reserve). Safe rolls are the floor of spendable cash divided by the live roll cost.
Roll A Gnome Roll Budget Calculator
Enter the cash balance and roll cost shown in your current server. The calculator protects a reserve, counts whole attempts, and shows any shortfall. It does not claim to know hidden odds, pity, future prices, or which gnome you will receive.

Calculated locally
Gnome roll budget
Enter a non-negative budget and a cost greater than zero using values from the live game.
The math runs in your browser and never asks for a Roblox login.
Why cost starts blank
A blank field is safer than carrying a price across an update or copying a cost from another game.
What this cannot predict
The tool does not predict rarity, luck effects, a future result, hidden pity, or the best point to stop.
Roll budget questions
What does the Roll A Gnome calculator do?
It converts your live cash, roll cost, protected reserve, and target into whole rolls, remaining cash, and any target shortfall.
Does it predict gnome rarity or luck?
No. It only performs transparent budget arithmetic and makes no probability claim.
Why is the roll cost blank?
Costs can change. Read the value from your current server rather than relying on a saved default.
Does the tool need my Roblox account?
No. The calculation runs in your browser and does not request credentials.
