Frequently asked questions

Does every Roblox transaction use a 30% fee?

No. The 30% default is useful for common experience monetization, while Avatar Marketplace and other transaction types can use different revenue shares.

Why can the target calculation be slightly above my requested amount?

Robux values are whole numbers. The calculator finds the smallest whole-Robux sale price that reaches at least your target after the selected fee.

Is this an official Roblox calculator?

No. This is an estimate, calculations happen locally in your browser, and Wid9et is not affiliated with Roblox Corporation.
