Roblox charges 1,000 Robux to change your username, which costs about $12.50 USD when you buy Robux at standard rates

The fee is fixed regardless of what you are changing your username to or how many times you have changed it before. You pay once per change, and the change takes effect when ready after you confirm it. There is no waiting period, no approval process, and no refund if you change your mind within a certain window — if you want to revert to a previous username, you pay the fee again.

The actual dollar amount you spend depends on how you buy Robux. If you purchase a 1,000 Robux package directly, the cost varies slightly by platform and region, but in the United States it is typically $12.50. If you already have Robux in your account from a previous purchase, you straightforward spend 1,000 of those Robux and nothing else happens. The fee itself never changes, but the real-world cost only applies if you need to buy Robux specifically for the username change.

Key Takeaways

  • Changing your Roblox username costs exactly 1,000 Robux, which is roughly $12.50 USD when purchased at standard rates.
  • The fee applies every time you change your username, so reverting to an old name costs the same as picking a new one.
  • You can change your username from your account settings on the Roblox website or mobile app without needing to contact support.
  • If you already own Robux from a previous purchase, you can use those instead of buying new ones.
  • The username change takes effect when ready and cannot be undone for free — changing back requires another 1,000 Robux.

How to change your username and pay the fee

Log into your Roblox account on the website or open the mobile app. Click on your avatar icon in the top right corner (website) or tap the menu icon (mobile app), then select Settings. Look for the Account tab and scroll down until you see the username field with a pencil icon next to it.

Click or tap the pencil icon to edit your username. Type your new username into the box — Roblox will tell you when ready if the name is already taken or contains blocked words. Once you enter a name that is available, you will see a prompt showing the cost: 1,000 Robux. If you have enough Robux in your account, click Buy or Confirm to complete the change. If you do not have enough Robux, the button will direct you to purchase more before you can proceed.

After you confirm, your username changes right away. You cannot undo this action through a settings menu — your only option to revert is to pay another 1,000 Robux and change it again.

When you need to buy Robux for the fee

If your account does not have 1,000 Robux saved, you will need to purchase a Robux package. Roblox sells Robux in bundles: the smallest package that covers the username change is 1,000 Robux for $12.50 on most platforms. You can also buy larger packages if you want extra Robux for other purchases like avatar items or game passes.

You can buy Robux directly from the Roblox website by clicking the Robux icon in the top right corner, or through the mobile app by tapping the Robux button in the menu. You will need a payment method on file — a credit card, debit card, PayPal account, or gift card. The purchase processes when ready, and your Robux balance updates within seconds.

Some players receive Robux as gifts from other users or earn small amounts through game development, but the standard way to get Robux for a username change is to buy it yourself. Roblox does not offer free Robux as part of the standard account, though the platform occasionally runs promotions for new or returning players.

Why Roblox charges for username changes

The fee exists to prevent spam and account cycling. Without a cost, players could change their usernames constantly to impersonate others, evade moderation, or confuse their friends. The 1,000 Robux price is high enough to discourage casual changes but low enough that players who genuinely want a new name can afford it without spending a large amount.

Roblox also uses the fee as a revenue source — the company keeps the Robux you spend, just as it does with Robux spent on any other purchase. This is standard practice for games that use a virtual currency system.

What happens if you change your mind

Once you change your username, you cannot reverse it for free. If you want to go back to your old username or pick something different, you must pay another 1,000 Robux. There is no grace period or undo button, and Roblox support does not reverse username changes even if you contact them when ready after making the change.

Before you confirm a username change, take time to think about whether you really want the new name. Check that it does not contain typos and that you will be happy with it long-term, since changing it again will cost you another 1,000 Robux.

Username change limits and restrictions

Roblox does not limit how many times you can change your username, but each change costs 1,000 Robux. Some players change their usernames frequently for roleplay, events, or personal reasons, and they straightforward pay the fee each time.

Your new username must follow Roblox's content policy — it cannot contain profanity, slurs, or references to real people without permission. If you try to set a username that violates the policy, Roblox will block it and tell you why. You will not be charged if the name is rejected.

You can change your username as often as you want, but there is no way to reserve a username or hold it while you decide. If someone else takes the name you want while you are thinking about it, that name becomes unavailable and you will need to pick something else.
