USD to Robux Calculator
See how many Robux your money buys — and what it's worth to a developer.
How dollars convert to Robux
Roblox sells Robux at roughly $0.0125 each, or 800 Robux for $10. The formula is USD ÷ 0.0125 = Robux, so $25 is about 2,000 Robux and $100 is about 8,000 Robux.
The calculator also shows the DevEx equivalent — how much earned Robux a developer would need to cash out that same dollar amount. Because the cash-out rate is $0.0038 per Robux, a developer needs far more Robux to receive the same money a player pays.
Use this when budgeting a commission, pricing a game pass, or agreeing on a Robux-based payment with a freelancer.
Frequently asked questions
How many Robux is $10?
$10 buys 800 Robux in the Roblox store at the standard rate of roughly $0.0125 per Robux.
How many Robux is $100?
$100 buys about 8,000 Robux at standard store pricing. Premium members and larger bundles get slightly more Robux per dollar.
Why do Premium members get more Robux?
Roblox Premium includes a monthly Robux stipend and a bonus on Robux purchases, so the effective price per Robux is lower for subscribers.
Is buying Robux the same as earning it?
No. Purchased Robux can be spent in experiences and on items, but it is not eligible for DevEx cash-out — only earned Robux is.
Does this calculator include taxes?
No. Store prices exclude local sales tax or VAT, which is added at checkout depending on your region.
