Capital One 360 lets you create multiple savings accounts within one login, each with its own balance and interest rate

Capital One 360 calls these separate accounts "sub savings accounts" or "buckets." You can create them directly in the app or on the website without opening a new account number or going through a second approval process. Each one earns the same interest rate as your main savings account, and you can move money between them instantly.

The main reason to use them is to organize money by goal. You might have one bucket for an emergency fund, another for a car down payment, and another for holiday spending. Seeing the balances separately makes it easier to track progress toward each goal without having to do math in a spreadsheet.

Key Takeaways

  • You can create up to 25 sub savings accounts in Capital One 360 from the app or website without any additional paperwork.
  • Each sub account earns the same interest rate as your main savings account and has no separate monthly fee.
  • Money moves between your main account and sub accounts instantly, and you can rename or delete sub accounts anytime.
  • Sub accounts do not have their own debit card or routing number — they are organizational tools only, not separate bank accounts.

How to create a sub savings account on the Capital One 360 app

Open the Capital One 360 app and tap the Savings tab at the bottom of the screen. You will see your main savings account listed. Tap the plus icon or "Add a Savings Account" button — the exact label varies by app version, but it is always near the top of the savings section.

Enter a name for the sub account. Use something specific: "Emergency Fund," "Car Down Payment," or "Vacation 2025" works better than "Savings 2" because you will see this name every time you check your balance. Tap Create or Confirm, and the sub account appears in your list immediately with a zero balance.

The new sub account is now ready to receive transfers. You do not need to set a minimum balance, and you do not need to wait for anything to process — it exists as soon as you name it.

How to create a sub savings account on the Capital One 360 website

Log into your Capital One 360 account at capitalone360.com. Click Savings in the left menu. You will see your main savings account and any existing sub accounts listed in a row or column.

Look for a button labeled "Add Savings Account," "Create New Account," or a plus icon. Click it. A form will appear asking you to name the new sub account. Type the name and click Create. The sub account appears in your account list within seconds.

If you do not see the button immediately, scroll down or check whether your browser is zoomed in too far — sometimes interface elements shift off-screen on smaller displays.

Moving money into and out of sub accounts

Once a sub account exists, you can transfer money to it from your main Capital One 360 savings account. In the app, tap the sub account name, then look for a Transfer or Move Money button. Select whether you are transferring in or out, enter the amount, and confirm. The transfer completes instantly — no waiting period.

On the website, click the sub account name to open it, then click Transfer. Choose the direction (from main account to sub, or vice versa), enter the amount, and submit. Again, the money moves right away.

You cannot transfer directly from a sub account to an external bank account or to another person. All transfers must go through your main Capital One 360 savings account first. If you need to send money out, move it to your main account, then use Capital One 360's external transfer feature.

Renaming or deleting a sub account

To rename a sub account, open it in the app or on the website and look for a Settings, Edit, or three-dot menu icon. Select Rename, type the new name, and save. The change takes effect immediately.

To delete a sub account, you must first move all its money out to your main account or another sub account. Once the balance is zero, open the account settings and select Delete. Capital One 360 will ask you to confirm. After you confirm, the sub account is gone and cannot be recovered, though the money you moved out remains in your main account.

If you delete a sub account by mistake, you cannot undo it. You will need to create a new one and transfer the money back in manually. For this reason, it is worth pausing before you delete, especially if the account holds money you care about.

Interest rates and fees on sub accounts

Every sub account in Capital One 360 earns the same interest rate as your main savings account. Capital One 360 does not charge a separate monthly fee for sub accounts, and there is no minimum balance requirement for any of them.

Interest is calculated daily on the balance in each sub account and paid monthly. If you have $5,000 in your main account and $3,000 in a sub account, you earn interest on both balances at the same rate. The interest appears as a single deposit to your main account each month, not to the individual sub accounts.

Because interest rates change over time, all your accounts — main and sub — will see the rate change together. You do not have to do anything when that happens.

Limits and what sub accounts cannot do

Capital One 360 allows up to 25 sub savings accounts per login. If you need more than that, you would have to open a second Capital One 360 account, which requires a separate login and Social Security number verification.

Sub accounts do not have their own routing number or account number. They are organizational buckets within your main account, not separate bank accounts. This means you cannot set up automatic deposits or bill payments to a sub account directly. Money must come from your main account or from external transfers to your main account first.

You also cannot link a sub account to a debit card, and you cannot write checks against it. All of those features work only with your main Capital One 360 savings account.

Frequently Asked Questions

Can I set up automatic transfers into a sub account?

Capital One 360 does not offer automatic recurring transfers to sub accounts through the app or website. You can set up a one-time transfer, but to automate deposits into a sub account, you would need to transfer money to your main account first, then manually move it to the sub account each month — or use a third-party automation tool like IFTTT if Capital One 360 supports it at the time you read this.

Do sub accounts have FDIC protection?

Yes. All balances in Capital One 360 sub accounts are covered by FDIC insurance up to $250,000 per depositor, per bank, per ownership category. The total across your main account and all sub accounts combined counts toward that limit, not each sub account separately.

Can someone else access my sub accounts?

Only if they have access to your Capital One 360 login. Sub accounts do not have separate passwords or PINs. If you give someone power of attorney over your account or add them as an authorized user, they will see all your sub accounts and can transfer money between them.

What happens to a sub account if I close my Capital One 360 account?

All sub accounts close along with your main account. Before you close, move any money you want to keep to another bank account. Once the main account is closed, the sub accounts are gone and cannot be reopened.
