On Roblox’s US web purchase page, 400 Robux is listed for $4.99 as of October 8, 2026. That is the displayed price to buy the package—not a cash value you can redeem. Roblox says Robux have no equivalent value in real currency.
What does 400 Robux cost?
The current US web listing pairs 400 Robux with $4.99. Roblox’s live page may show different prices, currencies, packages or bonuses depending on where you are, so check your local purchase page and the amount shown at checkout. The listed price may also have applicable taxes added. Roblox’s purchase page and its Terms of Use are the relevant references.
As a simple calculation, $4.99 divided by 400 is about $0.0125, or 1.25 cents, per Robux. This is only the implied cost per Robux in that package. It is not an official exchange rate, redemption rate or promise that Robux can be converted to cash.
Does 400 Robux have a cash value?
No fixed cash-equivalent value is established. Roblox’s Terms of Use state: “Robux are not a substitute for real currency, do not earn interest, and have no equivalent value in real currency.” In other words, the $4.99 figure describes what the package costs on the US web page, not what Roblox will pay you for 400 Robux.

Why might the checkout amount or Robux total differ?
Location and taxes
Roblox’s terms say the amount payable is the price indicated at purchase plus applicable taxes. For purchasers in the United States and Canada, applicable sales tax is separately stated and added. Prices and package details can vary by region, so use the checkout total rather than assuming the US listing applies everywhere.
Purchase channel and displayed bonuses
Roblox Support says web, computer and gift-card purchases receive up to 25% more Robux. “Up to” does not mean every package or purchase receives the same bonus. Check the amount displayed for the exact package and channel before paying. Roblox Support describes the offer.

Package comparisons
The US web purchase page also displays 240 Robux for $2.99 and 800 Robux for $9.99. These are separate package listings, not evidence of a universal rate: package size and any displayed bonus can change the implied cost per Robux. Compare the current checkout amounts if you are deciding between packages.
Can a Robux generator give you 400 for free?
No legitimate Robux generator exists. Roblox Support says offers of this kind are scams. Do not share your password or account details with a site or person promising free Robux; use Roblox’s official purchase channels instead. Roblox Support provides guidance on these offers.

Is a Roblox subscription the same as buying 400 Robux?
No. Roblox Plus was announced at $4.99 USD per month with a 10% discount on eligible in-game purchases, increasing to 20% beginning in a subscriber’s third consecutive month. That subscription price and discount do not establish that the 400-Robux package is always discounted; eligibility and transaction details matter. Roblox’s announcement gives the published terms.
Roblox Support says new Roblox Premium memberships stopped being available for purchase on April 30, 2026. Existing subscribers may retain their subscriptions subject to Roblox’s stated changes, so Premium should not be treated as an available new sign-up option. See Roblox Support for the membership update.
