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

Calculated locally
Crate purchase budget
Enter a non-negative budget and a cost greater than zero. The cost should come from the live game panel.
The calculation uses your input in this browser. It does not request a Roblox login or predict a unit outcome.
Why cost is blank
The cost stays blank because a particular crate and a batch can have different prices. Enter the offer you actually intend to buy.
What it cannot predict
A budget cannot predict the unit you will pull, guarantee a rare result, or establish a pity rule.
Calculator questions
What does this calculator count?
Whole purchases that fit after your reserve: floor(max(0, balance minus reserve) divided by the price you enter).
How do I calculate a batch purchase?
Enter the displayed full batch price as one purchase. A result of two means two batches, not two individual unit outcomes.
Does an affordable purchase count guarantee a rare unit?
No. This tool performs budget arithmetic. It does not model odds or pity.
Does the tool need my Roblox account?
No. Enter numbers only; the calculation runs in your browser.
