Saving up for something specific
Say a limited item costs 5,000 Robux and you already hold 1,200. Enter both and the tool works out the 3,800 you are missing and the cheapest packs to cover it. It is handy for items that sell out fast and for planning a purchase before payday.
Why the cheapest mix is not always the biggest pack
Sometimes two mid-size packs reach your goal for less than one oversized pack. The tool checks every combination so you do not overpay for Robux you will not spend.
Questions
Can I overshoot my goal?
Yes, packs are fixed sizes. The tool picks the cheapest total at or above your goal.
