What a Capital One 360 Savings Account Is and How Money Moves In and Out

Capital One 360 is an online bank, which means it has no physical branches—you deposit and withdraw money through transfers, not at a teller window. A Capital One 360 savings account is a deposit account where your money earns interest. You can move money into it from another bank account via ACH transfer (which takes one to three business days), and you can move money out the same way or by requesting a check.

The account itself is FDIC-insured up to $250,000, meaning if Capital One fails, the federal government covers your balance. You do not need a minimum balance to open one, though Capital One does not pay interest on zero balances. The interest rate changes based on what the Federal Reserve does with its benchmark rate—when the Fed raises rates, Capital One typically raises its savings rate within days or weeks; when the Fed cuts rates, Capital One cuts its rate as well.

You access the account through Capital One's website or mobile app. You can see your balance, transaction history, and current interest rate at any time. There are no monthly fees, no overdraft fees (because you cannot overdraft a savings account), and no minimum balance requirement.

Key Takeaways

  • Capital One 360 is an online-only bank, so you deposit and withdraw money through electronic transfers or checks, not in person.
  • Your money earns interest that compounds daily and is paid monthly, and the rate moves up or down when the Federal Reserve changes its benchmark rate.
  • Deposits from other banks take one to three business days to arrive via ACH transfer, and withdrawals take the same time to reach your other account.
  • The account is FDIC-insured up to $250,000 and has no monthly fees, minimum balance, or overdraft fees.
  • You can make up to six withdrawals per month before Capital One may charge a fee or restrict the account, though this rule is less common now than it was before 2020.

How Interest Works and When You Receive It

Capital One 360 calculates interest daily based on your balance. The interest rate is an annual percentage yield (APY), which already accounts for compounding. If your APY is 4.50% and you have $10,000 in the account, Capital One divides that rate by 365 days and applies it to your balance each day. The interest earned each day is added to your balance, so the next day's interest is calculated on a slightly larger amount.

Capital One pays the interest monthly, usually on the first business day of the month. The interest appears as a deposit in your account—you can see it in your transaction history. The amount you earn each month depends on your balance and the current APY. If your balance or the APY changes during the month, your interest payment reflects that change.

The APY is not fixed. Capital One adjusts it when the Federal Reserve changes its policy rate. You can check the current rate on Capital One's website or in the app. The rate you see when you open an account is not may provide to stay the same, so if rates fall, your earnings fall with them.

Depositing Money Into Your Capital One 360 Account

The most common way to deposit money is through an ACH transfer from another bank account you own. You provide Capital One with your other bank's routing number and your account number there. Capital One then initiates the transfer, which typically takes one to three business days. During that time, the money is in transit and not yet in your Capital One account.

You can also deposit by mailing a check to Capital One's address, though this is slower—mail takes several days to arrive, and Capital One takes additional time to process it. Some customers use a check deposit feature in the mobile app, which lets you photograph the front and back of a check and submit it electronically; Capital One then processes it as if you had mailed it.

You cannot deposit cash directly because Capital One has no branches. If you have cash, you must first deposit it into another bank account (at an ATM or branch), then transfer it to Capital One.

Withdrawing Money and Transfer Timelines

To withdraw money, you initiate an ACH transfer from your Capital One 360 account to another bank account you own. You provide the routing number and account number of the destination bank, and Capital One sends the money. The transfer takes one to three business days, just like a deposit. During that time, the money is in transit.

You can also request a check from Capital One, which you can mail to a third party or deposit elsewhere. Requesting a check through the app or website takes a few minutes, but the check itself takes several days to arrive by mail, and then the recipient must deposit it and wait for it to clear.

Capital One historically limited savings accounts to six withdrawals per month under a federal rule called Regulation D. If you exceeded six, Capital One could charge a fee or convert your account to a checking account. That rule was suspended in 2020 and has not been fully reinstated, so most customers can make unlimited withdrawals now. However, Capital One's terms still reference the limit, so it is worth checking the current policy on their website or calling customer service if you plan to make frequent withdrawals.

How Capital One 360 Differs From a Checking Account

A Capital One 360 savings account is designed for storing money and earning interest, not for everyday spending. You cannot get a debit card for a savings account, so you cannot swipe it at a store or withdraw cash from an ATM. You also cannot write checks directly from a savings account. Every transaction requires you to initiate a transfer or request a check, which takes time.

Capital One does offer a checking account (called Capital One 360 Checking) that works alongside the savings account. The checking account comes with a debit card and check-writing ability, making it better for bills and daily purchases. Many customers use both: the checking account for spending and the savings account for money they want to set aside and earn interest on.

The savings account also earns interest; the checking account typically does not. This is why people keep money in savings even though withdrawals take longer—the interest makes up for the inconvenience if you are not touching the money regularly.

Fees, Minimums, and Account Restrictions

Capital One 360 charges no monthly maintenance fee, no minimum balance fee, and no overdraft fee (overdrafts are not possible on savings accounts). There are no fees for ACH transfers in or out, and no fees for requesting checks. If you exceed the withdrawal limit under Regulation D (currently not enforced, but potentially six per month), Capital One may charge a fee of around $10 per excess withdrawal, though this is rare in practice now.

There is no minimum balance to open the account or keep it open. You can have $1 in the account and it will remain open. However, if your balance is very low, the interest you earn will be minimal—a $1 balance earning 4.50% APY generates less than a penny per month.

Capital One may close an account if it detects fraud, if you violate the terms of service, or if the account remains inactive for an extended period (typically one to two years with no deposits or withdrawals). If your account is closed, Capital One sends you a check for the remaining balance.

Security, FDIC Insurance, and What Happens If Capital One Fails

Your Capital One 360 account is protected by FDIC insurance, which covers up to $250,000 per depositor per bank. If you have $50,000 in the account and Capital One fails, the FDIC pays you the full $50,000. If you have $300,000, the FDIC covers $250,000 and you lose the rest. If you have multiple accounts at Capital One (such as a checking account and a savings account), the FDIC insurance limit applies to the total across all your accounts at that bank, not per account.

Capital One uses encryption and multi-factor authentication to protect your login. You can set up two-factor authentication through the app, which requires a code sent to your phone or email when you log in from a new device. You should never share your password or the codes sent to your phone.

If you notice a transaction you did not make, report it to Capital One immediately through the app or by phone. Capital One investigates unauthorized transactions and typically reverses them within a few business days. Your liability for fraudulent transactions is limited by federal law—you are generally not responsible for unauthorized charges if you report them promptly.

Frequently Asked Questions

Can I use my Capital One 360 savings account to pay bills?

Not directly. You cannot set up automatic bill payments from a savings account the way you can from a checking account. You would need to transfer money from savings to a checking account first, then pay the bill from checking. If you need to pay bills regularly, opening a Capital One 360 Checking account alongside the savings account is more convenient.

What happens if I need money before an ACH transfer completes?

You have to wait. ACH transfers take one to three business days, and there is no way to speed them up. If you need money urgently, you should keep some in a checking account or another account with immediate access. A savings account is best for money you do not need right away.

Does Capital One 360 offer any other account types?

Yes. Capital One 360 offers a checking account, money market accounts, and certificates of deposit (CDs). Money market accounts are similar to savings accounts but may have higher interest rates and require larger balances. CDs lock your money for a set term (three months to five years) in exchange for a higher rate.

Can I link my Capital One 360 account to other banks?

Yes. You can transfer money between Capital One 360 and any other bank account you own by providing the routing and account numbers. You can also link external accounts in the app to make transfers easier. Capital One does not charge fees for these transfers.

What is the current interest rate on Capital One 360 savings?

The rate changes frequently and varies based on Federal Reserve policy. You can see the current rate on Capital One's website or in the app. The rate you earn may differ slightly from the advertised rate depending on when you opened your account, though Capital One generally applies the same rate to all customers.
