You do not need Robux to change your username on Roblox

Changing your Roblox username is free. You can do it without spending any Robux, the in-game currency. The only cost is the one-time fee Roblox charges for the username change itself, which you pay with real money through your account balance or payment method — not with Robux.

Roblox separates its currency into two types: Robux (which you buy with real money and use inside games) and your account balance (which is what you use to pay for account services like username changes). When you change your username, you are paying for an account service, not buying something in a game, so Robux cannot be used.

Key Takeaways

  • Username changes cost real money through your Roblox account balance, not Robux.
  • The first username change is free; each change after that costs a set amount in real currency.
  • You can change your username once every 7 days, whether you have Robux or not.
  • If you do not have enough account balance to pay for a username change, you can add funds through your payment method before making the change.

How the cost works for your first and later changes

Your first username change on Roblox is free. You do not pay anything. After that, each additional username change costs 1,000 Robux worth of real money — currently around $12.50 USD, though the exact amount in your local currency depends on your region and current exchange rates.

The cost applies to your account balance, not a Robux wallet. When you go to change your username a second time, Roblox will show you the price and ask you to confirm the purchase. If your account balance is too low, you will need to add funds before you can complete the change.

The 7-day waiting period between changes

You can change your username once every 7 days. This limit applies whether you are paying or using your free first change. If you changed your username today, you cannot change it again for 7 days, even if you have the money ready.

This waiting period is a safety feature. It prevents account takeovers from quickly cycling through usernames to hide what happened, and it stops people from rapidly changing names to evade moderation or scams.

Where to find the username change option

Log into your Roblox account on the website. Click your avatar icon in the top right corner and select Settings. On the left side, click Account. Under the Account Information section, you will see your current username with an option to change it.

Click the change button, type your new username, and Roblox will tell you whether it is available. If it is, and if you have already used your free change or are paying for a subsequent change, you will see the cost and a confirmation button. Review the price, confirm, and the change takes effect when ready.

What happens if you do not have enough account balance

If you are trying to pay for a username change and your account balance is too low, Roblox will not let you complete the transaction. You will see a message telling you that you need more funds.

To add funds, go back to Settings, click Billing, and select Add Funds. Choose your payment method and the amount you want to add. Once the funds appear in your account balance, you can return to the username change screen and complete the purchase.

Why Robux cannot be used for username changes

Robux is designed for in-game purchases — cosmetics, game passes, and items within Roblox games. Account services like username changes, account upgrades, and premium memberships use your account balance instead. This separation exists because Robux is tied to individual games and developers, while account services are managed by Roblox itself.

If you have Robux but no account balance, you cannot use that Robux to pay for a username change. You will need to add real money to your account balance separately. Understanding this distinction helps you avoid confusion when you are ready to make a change to your account.

Frequently Asked Questions

Can I use a gift card to pay for a username change?

Yes. Roblox gift cards add funds to your account balance, which is what you use to pay for username changes. When you redeem a gift card, the balance appears in your account and can be used for any account service, including username changes.

What if I change my mind after paying for a username change?

Once you confirm a username change, it cannot be undone or refunded. The new username takes effect when ready and the payment is final. Make sure you want the new username before you click confirm.

Does the 7-day waiting period start from when I pay or when the change goes live?

The 7-day waiting period starts when ready when the username change takes effect. If you change your username on Monday, you cannot change it again until the following Monday, regardless of what time you made the change.

Can I change my username if my account is under 13?

Accounts under 13 have restrictions on many account services, including username changes. If your account is under 13, you may not be able to change your username at all, or you may need parental permission. Check your account settings to see what options are available for your age group.
