You can add a savings account to Capital One through the mobile app, online banking portal, or by calling customer service
The fastest way is through the Capital One mobile app or website: log in, go to Accounts, select Add Account, and follow the prompts to choose a savings product. Capital One offers several savings account types—360 Savings, Money Market, and high-yield savings—and the app will show you the current interest rates and features for each before you commit. The entire process takes about five minutes and the account is usually active within one business day.
If you prefer to speak with someone, call Capital One's customer service number on the back of your debit card or statement. A representative can walk you through the options, answer questions about fees and minimum balances, and open the account over the phone. You do not need to visit a branch; Capital One operates primarily as an online bank with no physical locations.

Adding a savings account through the mobile app
Open the Capital One mobile app and log in with your username and password. Tap the menu icon (three horizontal lines) and select Accounts or a similar option depending on your app version. Look for an "Add Account" or "Open New Account" button, usually near the top of the Accounts section.
The app will show you the savings products Capital One currently offers. Read the interest rate, minimum opening deposit (usually $0), and any other features listed for each account type. Select the one you want and follow the prompts, which typically ask you to confirm your personal information, choose a funding source (transfer from an existing Capital One account or external bank), and set a PIN or password if needed.
After you submit, you will see a confirmation screen with your new account number. The account is usually available for deposits and transfers within one business day, though some transfers from external banks take longer depending on the sending bank's processing time.
Adding a savings account through online banking
Go to capitalone.com and log in. Click on Accounts or a similar navigation option at the top of the page. Look for "Open a New Account" or "Add Account" and select it.
You will be taken through the same product selection and information entry as the app. The online portal may ask for additional verification, such as a code sent to your phone or email, before the account is finalized. Once confirmed, your new savings account will appear in your account list within one business day.
Linking a new savings account to an existing checking account
If you already have a Capital One checking account, the new savings account will automatically be linked to it. This means you can transfer money between the two accounts instantly through the app or website without any additional setup.
To move money between them, go to Transfers in the app or website, select the checking account as the source and the savings account as the destination, enter the amount, and confirm. Transfers between your own Capital One accounts are free and usually complete within minutes. If you are transferring from an external bank account to fund the savings account, that transfer may take one to three business days depending on the sending bank.
What information you will need to provide
Capital One will ask for your Social Security number, date of birth, and current address. If you are opening the account as a new customer (not linked to an existing Capital One account), you may also need to provide a government-issued ID number and answer security questions to verify your identity.
Have your existing Capital One account number handy if you want to fund the new savings account from another Capital One account. If you are funding it from a bank outside Capital One, have that bank's routing number and your account number ready.
Choosing between Capital One savings products
Capital One's 360 Savings account is the most common choice for everyday savers. It has no monthly fees, no minimum balance requirement, and earns interest on whatever you deposit. The interest rate changes based on market conditions, so check the current rate when you open.
Capital One Money Market accounts typically offer higher interest rates than savings accounts but may require a larger opening deposit and have limits on how many withdrawals you can make per month. If you are saving for a specific goal and do not plan to touch the money often, a Money Market account may pay more interest. If you need flexibility and frequent access, the 360 Savings account is usually the better choice.
Compare the current rates and features on the app or website before you decide. The rates change regularly, so what was the best option last month may not be today.
What happens after you open the account
Your new savings account will appear in your Capital One app and online banking immediately after opening, though deposits and transfers may take a day to process depending on the funding source. You can set up automatic transfers from your checking account to build savings on a schedule—for example, $50 every payday.
Capital One will send you a confirmation email with your new account number and details. Keep this for your records. You do not need to do anything else to activate the account; it is ready to use as soon as the opening process is complete.
Frequently Asked Questions
Can I open a Capital One savings account if I do not have a checking account with them?
Yes. You can open a savings account as a standalone account without an existing Capital One checking account. The process is the same, and you can fund it from an external bank account or with an initial deposit.
How long does it take for money to show up in the new savings account?
If you transfer from an existing Capital One checking account, the money appears within minutes. If you transfer from an external bank, it typically takes one to three business days depending on the sending bank's processing time. Deposits made by check or cash at a Capital One ATM may take longer.
Are there any fees for opening or maintaining a Capital One savings account?
Most Capital One savings accounts have no monthly maintenance fees, no minimum balance fees, and no fees for transfers between your own accounts. Confirm the current fee structure when you open, as terms can change.
Can I close the savings account later if I change my mind?
Yes. You can close a Capital One savings account anytime through the app, website, or by calling customer service. Transfer any remaining balance to another account first, then request the closure. The account will be closed within one to two business days.
What is the interest rate on Capital One savings accounts?
Interest rates vary by account type and change based on market conditions. Check the current rate on the Capital One website or app before you open. The rate you see when you open is the rate you will earn, though Capital One can change rates in the future with notice.
