Compare equal-priced optional purchases using a budget, price and reserve you enter. This arithmetic tool does not supply game prices, predict survival or assume a purchase changes an ending.
Use the same unit for the budget, price and reserve. Enter a price only when you can observe the actual offer; do not use this tool as an offer list.
Values are calculated in this browser. No Roblox login is needed.
Spendable budget is the larger of zero and budget minus reserve. Divide that amount by the equal price and round down. The remainder stays after all whole purchases; the tool also compares your target count with the available amount.
A larger count does not establish a useful reward, survival benefit or different story outcome. Choose a spending limit independently of the maximum count. No game-specific offer, price or effect is prefilled.
The formula assumes each purchase has the same price. If the next price differs, calculate it separately. Do not mix Robux with another resource or treat unlike units as interchangeable.
No. You supply the price and budget. Blank defaults avoid presenting an unverified offer as a current price.
No. It calculates whole equal-priced purchases, not story outcomes, hiding success or reward odds.
It protects an amount you choose before the whole purchase count is calculated. If the reserve exceeds the budget, the spendable amount is zero.
