How to Use the Robux Calculator
Our Robux Calculator converts between USD and Robux in real time. Whether you want to know how much a Robux package costs in dollars or how many Robux you can get for a given budget, this tool gives you instant results.
- Select a Roblox package — Choose from the six official Robux packages ($4.99 to $199.99) to instantly see the Robux you receive at that price point.
- Toggle Roblox Premium — If you have an active Premium subscription, enable the toggle to add the 10% bonus to any package calculation automatically.
- Enter a custom USD amount — Type any dollar amount in the USD field to calculate how many Robux it would buy at the standard $0.0125 per Robux rate.
- Or enter Robux — Type a Robux amount to reverse-calculate how much it would cost in USD, including any Premium adjustments.
- Copy the result — Click the copy button to save your converted Robux amount to the clipboard for quick reference.
All calculations use the official Roblox store pricing as of 2026. Premium members receive 10% extra Robux on every purchase, and this calculator accounts for that bonus automatically when the toggle is enabled.

Why Use Our Robux Calculator?
Roblox does not display a simple per-Robux price on its website, which makes it hard to compare package values or figure out the best deal. Our calculator solves this by showing you the exact exchange rate for every package, including the Premium bonus. Unlike other converters, we use the real official store prices — not outdated or estimated rates. This tool is especially useful for parents budgeting for their children's Roblox spending, developers estimating DevEx cashouts, and players deciding which package gives the most value per dollar.
