The cost depends on how many times you have changed it before

Your first username change costs 1,000 Robux. If you change it again, the second change costs 1,000 Robux. The third change costs 1,000 Robux. But starting with your fourth change in the same account, the price jumps to 10,000 Robux per change, and it stays at 10,000 Robux for every change after that.

Roblox sets these prices to discourage people from switching usernames constantly. The jump at the fourth change is steep enough that most players stop there or wait a long time between changes.

Key Takeaways

  • Your first three username changes each cost 1,000 Robux, regardless of how long you wait between them.
  • Starting with your fourth change, each username change costs 10,000 Robux and remains at that price for all future changes.
  • You must have the Robux in your account balance before you start the change — you cannot use Robux from a gift card or pending purchase.
  • Once you change your username, the old name becomes available for other players to claim after a short waiting period.

How to check your current Robux balance

Open Roblox and look at the top right corner of the screen. You will see a number next to a Robux icon (it looks like a gold coin with an R). That number is how much Robux you have available to spend right now. If you do not see it, you may be logged out — log in and check again.

The balance shown is only the Robux you own outright. If you have Robux waiting to be added from a gift card or a pending purchase, those will not show in this balance yet. You need the full amount already in your account to change your username.

Where to buy Robux if you do not have enough

You can buy Robux directly from Roblox using a credit card, debit card, gift card, or through your platform's payment system (like Google Play on Android or the App Store on iOS). Go to your account settings, find the Robux section, and choose how much you want to buy. Prices vary slightly by region and by how much you purchase at once.

You can also earn Robux by creating items in Roblox Studio and selling them to other players, but this takes time and requires you to be at least 13 years old and have a Premium membership. For most players who need Robux quickly, buying it is the only practical option.

What happens after you pay the Robux

Once you confirm the payment and the Robux is deducted from your balance, your username changes when ready. You will be logged out and then logged back in with your new username. Any games you were playing will close, so save your progress first if you are in the middle of something.

Your old username becomes available for other players to claim after a waiting period. Roblox does not publicly state exactly how long this period is, but it is typically a few days to a week. During that time, no one else can use your old name.

Why the price increases after the third change

Roblox uses the price jump to prevent account takeovers and impersonation. If someone gains access to your account, they could change your username repeatedly to confuse your friends or damage your reputation. The high cost after the third change makes this attack much more expensive and less appealing to attackers.

The price structure also encourages players to choose a username they actually want to keep. If changing your name is cheap and straightforward, people do it constantly, which makes it harder for friends to find you and creates confusion in the community.

What you cannot do with a username change

You cannot transfer your username to another account, even if you own both accounts. When you change your username, the old one straightforward becomes available for anyone else to claim. You also cannot reserve a username in advance or put a hold on one you want — you can only claim it by changing to it.

If someone else claims your old username before you decide you want it back, you cannot get it back from them. Roblox does not restore old usernames or force other players to give them up.

Frequently Asked Questions

Can I change my username without spending Robux?

No. Every username change requires Robux, with no exceptions. There is no free way to change your username on Roblox, even if you have never changed it before.

What if I change my mind right after paying?

Roblox does not refund Robux spent on username changes. Once the change is complete, the Robux is gone and your old username is released. If you want your old username back, you would have to pay again to change to it — but only if no one else has claimed it in the meantime.

Do I need Premium membership to change my username?

No. Any account can change its username as long as it has enough Robux. Premium membership is not required.

How long does the username change take to go through?

The change happens when ready once you confirm and pay. You will be logged out and logged back in with your new username within seconds.

Can I change my username on mobile the same way as on computer?

Yes. The process is the same whether you use the Roblox app on your phone or the website on a computer. You go to your account settings, find the username option, and pay the Robux to confirm the change.
