How Robux to USD Conversion Works (Purchase vs. DevEx Rate)
Purchase Rate = $4.99 / 400 Robux = $0.012475 per Robux
DevEx Rate = $350 / 100,000 Robux = $0.0035 per Robux
Purchase Rate (Buying)
This is the rate any player pays when buying Robux directly through Roblox with real money, via one of Roblox's fixed purchase bundles (e.g., 400 Robux for $4.99). It applies to spending on avatar items, game passes, and in-experience purchases.
DevEx Rate (Cash-Out)
This is the rate Roblox pays eligible developers who cash out Robux they've earned from their experiences through the Developer Exchange program. It's substantially lower than the purchase rate — the gap is Roblox's platform margin.
Frequently Asked Questions
What is the Robux to USD conversion rate?
Robux converts to USD at two different rates depending on context. The purchase rate — what you pay to buy Robux — is about $0.0125 per Robux (400 Robux = $4.99). The DevEx cash-out rate — what eligible creators receive when they redeem Robux for real money — is about $0.0035 per Robux (100,000 Robux = $350).
How much is 400 Robux in real money?
At the standard purchase rate, 400 Robux costs $4.99 USD. If you were instead cashing out 400 Robux through DevEx, it would only be worth about $1.40, since the cash-out rate is roughly 3.5x lower than the purchase rate.
Why are there two different Robux to USD rates?
The purchase rate is what Roblox charges players buying Robux with real money through the Roblox platform. The DevEx (Developer Exchange) rate is what Roblox pays eligible developers and creators who cash out Robux earned from their experiences, back into real money. Roblox keeps the difference as its platform margin, which funds hosting, payment processing, and the creator ecosystem.
Can any player cash out their Robux for cash?
No. Only developers and creators enrolled in the Developer Exchange (DevEx) program can convert Robux into real money, and only after meeting eligibility requirements, including a minimum Robux balance and account standing. Robux earned from gameplay, gifts, or Premium stipends generally cannot be cashed out by regular players.
Does the Robux to USD rate change over time?
Roblox has adjusted both rates in the past, and the DevEx rate in particular has ranged between roughly $0.0035 and $0.0038 per Robux depending on the current published rate. Always check Roblox's official DevEx and purchase pages for the current live rate before relying on this calculator for a real transaction.
Data Accuracy & Source Note
Rates reflect Roblox's publicly listed purchase price (400 Robux = $4.99) and Developer Exchange rate ($350 per 100,000 Robux) at the time of writing. The DevEx rate has historically ranged between roughly $0.0035 and $0.0038 per Robux and is set solely by Roblox — always confirm the current live rate on Roblox's official purchase and DevEx pages before relying on this tool for an actual transaction or payout estimate.
