The cost to change your Roblox username is 1,000 Robux, which converts to roughly $12.50 USD at standard exchange rates, though the exact dollar amount varies by your location and current Robux pricing.

Roblox sets the price in Robux, not dollars. When you buy Robux to cover the change, you typically purchase more than you need because Robux bundles come in fixed amounts — the smallest bundle that covers 1,000 Robux costs more than 1,000 Robux alone. If you already own Robux from previous purchases or earned them through game development, you can use that balance instead of spending new money.

The username change itself is permanent once you confirm it. You cannot revert to your old name, and you cannot change your username again for 30 days after the first change. This waiting period resets each time you make a change.

Key Takeaways

  • Changing your username costs 1,000 Robux, which typically requires buying a Robux bundle that costs between $9.99 and $19.99 depending on how many Robux you need.
  • If you already own Robux from game earnings or previous purchases, you can use that balance without spending additional money.
  • You must wait 30 days between username changes, and the old name becomes available for other players to claim after you change it.
  • The username change is permanent — Roblox does not restore old usernames or let you switch back after the change is complete.

How to find the username change option in your account settings

Log into your Roblox account on the website or mobile app. Click your avatar icon in the top right corner and select Settings. On the Settings page, look for the Account tab on the left side. Under Account, you will see a field labeled Username with your current name displayed. Next to it is a button or link to change it — the exact label varies slightly between the website and app, but it usually says Change or shows an edit icon.

Click that button to open the username change dialog. Type your new username into the text field. Roblox will check in real time whether the name is available — if another player already has it or if it violates Roblox content rules, you will see a message saying the name is taken or not allowed. Once you find an available name you want, the system will show you the 1,000 Robux cost and ask you to confirm.

What happens if you do not have enough Robux

If your account balance is below 1,000 Robux, the change button will be disabled or will prompt you to buy more Robux before proceeding. Roblox will direct you to the Robux purchase page, where you can choose a bundle. The smallest bundle is typically 400 Robux for $4.99, but that is not enough — you need at least 1,000 Robux. The next tier up is usually 800 Robux for $9.99, which still falls short. The 1,700 Robux bundle for $19.99 is the first one that covers the cost with room to spare.

Some players buy the 800 Robux bundle and then a smaller bundle to reach 1,000, which costs more overall than buying a single larger bundle. Check the bundle prices before you purchase — Roblox occasionally runs promotions that change the Robux-to-dollar ratio, so the exact cost can shift.

The 30-day waiting period between changes

After you change your username, you cannot change it again for 30 days. This timer starts the moment you confirm the change, not when the change takes effect. If you change your mind when ready after, you are locked out until the 30 days pass. There is no way to bypass this waiting period or request an exception.

During those 30 days, your old username becomes available for other players to claim. If someone else takes it before the waiting period ends, you cannot get it back — even after 30 days have passed and you are may be able to access to change again. Plan your new username carefully, because changing back is not an option.

Earned Robux versus purchased Robux

If you develop games or items in Roblox Studio, you can earn Robux through sales and in-game purchases. This earned Robux can be used for a username change just like purchased Robux. You do not have to spend real money if you have enough earned balance. However, earned Robux have a withdrawal limit — you can only cash out earned Robux to real money under certain conditions, and not all earned Robux are withdrawable. The Robux you use for a username change is straightforward deducted from your total balance, whether it came from purchases or earnings.

Check your Robux balance on the Settings page under the Account tab. Your balance shows your total Robux available, combining both earned and purchased amounts. The system does not distinguish between them when you spend.

What to do if you change your mind after paying

Once you confirm a username change and the Robux are deducted, the change is final. Roblox does not refund the Robux or reverse the username change under any circumstances, even if you contact support when ready after. The company treats username changes as permanent transactions. If you realize you made a mistake, your only option is to wait 30 days and change to a different username — you cannot restore your old name.

Before you confirm the change, take time to make sure the new username is exactly what you want. Check that it is spelled correctly, that it fits the tone you want, and that you will not regret it. Once the dialog asks for final confirmation, that is your final note to cancel without losing the Robux.

Username change costs on different devices

The Robux cost is the same whether you change your username on the Roblox website, the mobile app, or through a game — it is always 1,000 Robux. However, the process of buying Robux may differ slightly between platforms. On the website, you can buy Robux directly through your browser. On mobile, you purchase through the app store (Apple App Store or Google Play), and the payment method is tied to your device's account rather than Roblox directly. The final cost in your local currency may vary slightly depending on your region and the app store's exchange rates.

If you are on mobile and the Robux purchase seems more expensive than on the website, that difference is usually due to app store fees and regional pricing adjustments, not a Roblox surcharge. Compare prices across platforms if you want to minimize what you spend.

Frequently Asked Questions

Can I change my username for free?

No. Roblox charges 1,000 Robux for every username change, with no exceptions or free changes. The only way to avoid the cost is to not change your username at all.

What if someone else takes my old username after I change mine?

Your old username becomes available when ready after you change it, and another player can claim it. Once they do, you cannot get it back. Roblox does not hold old usernames in reserve or allow you to reclaim them later.

Do I have to buy Robux with real money, or can I earn enough for free?

You can earn Robux through game development and sales in Roblox Studio, but earning 1,000 Robux takes significant time and requires building a game or item that other players purchase. Most players buy Robux directly. If you do earn Robux, you can use that balance for a username change without spending money.

Can I change my username more than once?

Yes, but you must wait 30 days between changes, and each change costs 1,000 Robux. There is no limit to how many times you can change your username over time, as long as you pay the cost and wait the required period.

What if I buy Robux but then decide not to change my username?

The Robux stay in your account and do not expire. You can use them for other purchases in Roblox — like avatar items, game passes, or private servers — or save them for a future username change.
