On Roblox’s US web purchase page, 400 Robux is listed for $4.99 as of October 8, 2026. That is the price of a package, not a cash value: Roblox says Robux have no equivalent value in real currency.
How much does 400 Robux cost?
Roblox’s live US web purchase page lists 400 Robux for $4.99. The same page lists 240 Robux for $2.99 and 800 Robux for $9.99; package prices and displayed amounts can change. Check Roblox’s US Robux purchase page for the current offer.
Dividing $4.99 by 400 gives an implied purchase cost of about 1.25 cents per Robux. This is arithmetic based on the displayed package price—not an official conversion rate or a promise that Robux can be redeemed for cash.
Does 400 Robux have a cash value?
No 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 tells you what the package costs on the US web page, not what Roblox will pay you for 400 Robux.

Purchase channel and bonus Robux
Roblox Support says purchases made on the web, computer, and with gift cards receive up to 25% more Robux. “Up to” is not a guaranteed bonus for every purchase: check the amount displayed for your specific offer and channel before paying. A larger package or bonus also does not create a stable cash exchange rate. See Roblox Support’s Robux purchase guidance.

Region and taxes
The $4.99 amount is the US web display, not a global price. Roblox’s terms say the purchase price is the price indicated at checkout plus applicable taxes. For US and Canadian purchasers, applicable sales tax is stated separately and added. If you are elsewhere, use your local Roblox purchase page and the price shown at checkout.
Is Roblox Plus a discount on 400 Robux?
Not necessarily. Roblox announced Plus at $4.99 USD per month, with a 10% discount on eligible in-game purchases and a 20% discount beginning in a subscriber’s third consecutive month. Those subscription terms do not establish that the 400 Robux package is always discounted; eligibility and the applicable discount depend on the transaction. Roblox’s Plus announcement has the launch details.

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’s Premium information.

Do not use sites, videos, or apps promising free Robux through a generator. Roblox Support says there is no such thing as a Robux generator and calls these offers scams. Use Roblox’s official purchase options instead.
