What you need to open a Capital One savings account
Capital One offers two main savings accounts: the 360 Savings Account (online only) and the Money Market Account (also online). Both require you to start with a minimum deposit, though the amount varies. You will need a valid government-issued ID, your Social Security number, and either a checking account at another bank or a debit card to fund the initial deposit.
The entire process happens online and takes about 10 to 15 minutes. You do not need to visit a branch or call anyone—you can complete it from your computer or phone. Capital One will verify your identity using information from credit bureaus and public records, so the account opens immediately in most cases.
If you already have a Capital One checking account, opening a savings account is faster because Capital One already has your information on file. You can link the two accounts and transfer money between them without fees.
Key Takeaways
- You need a valid ID, Social Security number, and a way to fund your first deposit—either from another bank account or a debit card.
- The 360 Savings Account has no monthly fees and no minimum balance requirement after you open it, though there is an opening deposit minimum.
- The entire account opening process happens online and usually completes in minutes, with no branch visit required.
- If you already bank with Capital One, you can link your new savings account to your checking account and move money between them instantly.
- Capital One uses your credit report and public records to verify your identity, so you will know within minutes whether your account is approved.
Step-by-step: opening the account online
Start at Capital One's website and select "Open an Account." Choose between the 360 Savings Account or the Money Market Account—most people choose the 360 Savings because it has no monthly maintenance fee. Click "get your free guide" and you will be asked to enter your email address and create a password.
Next, enter your personal information: full name, date of birth, Social Security number, and current address. Capital One will run a soft credit check (which does not affect your credit score) to verify your identity. This usually takes a few seconds.
Then you will choose how to fund the account. If you have a checking account at another bank, you can link it and transfer money electronically. If you prefer, you can use a debit card instead. Enter the amount you want to deposit—Capital One's opening deposit minimum is currently $0 for the 360 Savings Account, though some promotions may require a higher deposit to earn a bonus rate.
Review the account terms and disclosures, check the box to agree, and submit. Your account number will appear on screen immediately. You can start using the account right away, though it may take one to two business days for your initial deposit to show up if you transferred from another bank.
Funding your account: bank transfer versus debit card
A bank transfer (also called an ACH transfer) is the most common way to fund a new savings account. You provide your routing number and account number from your existing bank, and Capital One pulls the money electronically. This is free and usually takes one to two business days. You can set up the transfer during account opening or add it later in your online dashboard.
If you do not want to share your bank account details, you can use a debit card instead. Capital One accepts Visa, Mastercard, Discover, and American Express. The transfer is instant, but Capital One may charge a small fee (usually $1 to $3) for debit card funding. Check the terms before you complete the transfer.
Once your account is open, you can deposit money by transferring from another bank account, moving money from a Capital One checking account, or setting up automatic transfers on a schedule. You cannot deposit cash or checks directly into a Capital One online savings account—there are no branches to visit.
What happens after you submit your application
Capital One verifies your identity using information from credit bureaus and public records. In most cases, this takes seconds and your account opens immediately. You will see your account number and routing number on screen, and you can log in to your account right away.
In rare cases, Capital One may need additional information—for example, if your name or address has changed recently or if there is a mismatch in the records. If this happens, you will receive an email or phone call within one business day asking you to provide documents like a utility bill or lease. Once you submit those, the account usually opens within 24 hours.
If Capital One declines your application, you will receive a letter in the mail explaining why. Common reasons include a history of unpaid overdrafts at other banks, fraud concerns, or a ChexSystems report (a banking history report similar to a credit report). You can dispute information in your ChexSystems report by contacting ChexSystems directly.
Linking your Capital One accounts and moving money
If you already have a Capital One checking account, you can link it to your new savings account in your online dashboard. Go to "Accounts," select "Link Account," and choose your checking account from the list. The link is instant and has no fee.
Once linked, you can transfer money between your checking and savings account anytime, and the transfer is usually instant. This is useful if you want to move money to savings quickly or if you need to pull money back to checking for a bill payment. There is no limit on how many transfers you can make between your own accounts.
If you have a checking account at a different bank, you can still transfer money to your Capital One savings account, but it will take one to two business days and you will need to set it up as an external transfer. Go to "Move Money," select "Transfer to Another Bank," and enter the routing and account number of your other bank.
Interest rates and account features
Capital One's 360 Savings Account earns interest on your balance. The rate changes based on market conditions and Federal Reserve decisions, so it is not fixed. You can check the current rate on Capital One's website before you open the account. Interest is compounded daily and deposited into your account monthly.
The Money Market Account typically offers a higher interest rate than the regular savings account, but it may have a higher opening deposit requirement and may limit how many withdrawals you can make per month. Check the current terms on Capital One's website to compare.
Both accounts have no monthly maintenance fee, no minimum balance requirement (after opening), and no fees for transfers between your own accounts. You will not be charged for overdrafts because a savings account cannot overdraft—if you try to withdraw more than you have, the transaction will simply be declined.
Frequently Asked Questions
Can I open a Capital One savings account if I do not have a checking account?
Yes. You can fund your savings account with a debit card instead of a bank transfer. Capital One may charge a small fee ($1 to $3) for debit card funding, but you do not need an existing checking account. Once your savings account is open, you can use it to receive direct deposits or transfers from other people.
How long does it take to open the account?
The online application takes about 10 to 15 minutes. In most cases, your account opens immediately after you submit, and you can see your account number on screen. If Capital One needs to verify additional information, it may take up to 24 hours, but this is rare.
What if I already have a Capital One checking account?
Opening a savings account is faster because Capital One already has your information. You can link the two accounts in your online dashboard and transfer money between them instantly with no fee. You will not need to provide your ID or Social Security number again.
Can I deposit cash or checks into my Capital One savings account?
No. Capital One has no physical branches, so you cannot deposit cash or checks in person. You can only fund the account by transferring from another bank, using a debit card, or moving money from a Capital One checking account. If you need to deposit a check, you can deposit it into another bank account first, then transfer the money to Capital One.
What is the difference between the 360 Savings Account and the Money Market Account?
The Money Market Account typically offers a higher interest rate, but it may have a higher opening deposit requirement and may limit withdrawals to a certain number per month. The 360 Savings Account has no withdrawal limits and no monthly fee. Compare the current rates and terms on Capital One's website to decide which fits your needs.
