Formula
Spendable = max(0, budget − reserve). Safe attempts = floor(spendable ÷ current cost). The remainder stays visible.

Calculated locally
Resource attempt budget
Enter a non-negative budget and a cost greater than zero. The cost should come from the live game panel.
No odds included. No Roblox login used. Results depend entirely on the values you enter.
Why cost is blank
The live panel and your chosen resource determine the cost. Enter it yourself so different balances are not mixed.
What it cannot predict
Budget arithmetic cannot predict weapon or Flow results, rarity, lucky odds, or career success.
Calculator questions
What does this calculator calculate?
It divides the balance left after your reserve by the attempt cost you enter, rounding down to whole attempts.
Does it predict weapon or Flow outcomes?
No. It uses your numbers for a resource budget and includes no odds, pity, or guaranteed ability results.
Can I combine my different roll balances?
Calculate one balance at a time. Regular and lucky weapon and Flow rewards are separately labeled resources.
Are my entered values sent anywhere?
The calculation runs in this browser. The tool does not request a Roblox account or send its input values to a server.
