Capital One has no minimum deposit to open a savings account

You can open a Capital One 360 Savings Account with $0. There is no minimum balance requirement to start the account, and no monthly fee if you keep a zero balance. You fund the account after it is open, on your own timeline.

Capital One does charge a monthly fee—currently $0.25 per month—but only if your account sits inactive for 12 consecutive months. If you make at least one deposit, withdrawal, or transfer during any 12-month period, the fee does not explore. Most people never encounter this fee because any regular use prevents it.

The account itself is a money market savings account, which means it earns interest on whatever balance you hold. The interest rate changes with market conditions and varies based on how much money you have in the account—higher balances earn higher rates. Capital One publishes current rates on their website, and you can see the exact rate before you open.

Key Takeaways

  • You need $0 to open a Capital One 360 Savings Account; there is no minimum deposit or opening balance required.
  • The account has no monthly maintenance fee as long as you use it at least once every 12 months.
  • A $0.25 monthly fee applies only if the account remains completely inactive for a full year.
  • Interest rates on the account vary by balance tier and change with market conditions, so check Capital One's current rates before opening.
  • You can fund the account after opening it by linking a bank account, transferring from another Capital One account, or depositing a check by mobile app.

How to fund the account after opening

Once your account is open, you have several ways to add money. The most common method is linking an external bank account and transferring funds electronically. This typically takes one to two business days to complete. You can link a checking account from any U.S. bank.

If you already have a Capital One checking account, you can transfer between your own accounts when ready within the Capital One app. You can also deposit checks using Capital One's mobile check deposit feature—photograph the front and back of the check, and the funds usually appear within one business day.

Capital One does not accept cash deposits at branches or ATMs, and there is no way to deposit cash directly into a 360 Savings Account. If you need to deposit cash, you would have to deposit it into a checking account at another bank first, then transfer it to Capital One.

Interest rates and how they change

Capital One's savings rates are tiered, meaning you earn different rates depending on your balance. A higher balance earns a higher rate. The exact tiers and rates change frequently—sometimes weekly—based on what the Federal Reserve does with interest rates. You can see the current rates on Capital One's website without opening an account.

Unlike some savings accounts, Capital One does not require you to maintain a specific balance to earn the highest rate. You earn whatever rate applies to your current balance, and if your balance grows, your rate automatically increases at the next tier. Interest compounds daily and is credited to your account monthly.

The rates Capital One offers are typically competitive with other online banks, though they fluctuate. If you are comparing Capital One to other options, check the rates on the same day, because they can shift quickly.

Account features and limitations

Capital One 360 Savings is an online-only account, which means you cannot visit a physical branch to deposit money or speak to someone in person. All transactions happen through the mobile app, website, or by phone. Customer service is available by phone, email, and chat.

The account comes with a debit card, but it is not designed for everyday spending—it is meant for accessing your savings. You can use it to withdraw cash at ATMs in the Allpoint network, which includes over 55,000 ATMs worldwide. Capital One does not charge a fee for these withdrawals, though the ATM operator may.

Federal law limits you to six transfers or withdrawals per month from a savings account (not counting ATM withdrawals). If you exceed this limit, Capital One may charge a fee or convert your account to a checking account. This rule applies whether you transfer money out, write a check against the account, or use a debit card.

Comparing Capital One to other online savings accounts

Capital One's main advantage is that you can open with zero dollars and there is no monthly fee if you use the account. Many other online banks have similar or slightly higher interest rates but also have no minimum balance and no monthly fees, so the choice often comes down to which interface you prefer and whether you already bank with Capital One.

If you already have a Capital One checking account, opening a linked savings account is straightforward—you can transfer between them when ready and manage both from one app. If you are starting from scratch, you might compare Capital One's current rate to rates at other online banks like Ally, Marcus, or American Express Personal Savings to see which offers the best rate for your situation.

Some banks offer higher rates but require larger minimum balances or have monthly fees. Others offer lower rates but include features like in-person branch access. There is no single best choice—it depends on what matters to you: rate, convenience, features, or whether you want to keep all your accounts in one place.

What happens if you do not use the account

If your Capital One 360 Savings Account sits completely inactive for 12 consecutive months—meaning no deposits, withdrawals, transfers, or interest credits—Capital One will charge a $0.25 monthly fee. This fee continues each month until you use the account again.

If the account remains inactive and the fee is charged for long enough, your balance could eventually reach zero. Capital One may then close the account. However, this is rare because most people either use their savings account or close it if they no longer need it.

If you think you might not use the account for a while, you can straightforward not open it, or you can close it after opening if your circumstances change. There is no penalty for closing a Capital One savings account.

Frequently Asked Questions

Do I have to keep a minimum balance in the account?

No. Capital One has no minimum balance requirement. You can open the account with $0 and keep it at $0 indefinitely. The only fee you might face is the $0.25 monthly inactivity fee if the account sits unused for 12 straight months.

Can I open a Capital One savings account if I do not have a checking account?

Yes. You do not need to have a Capital One checking account or any other bank account to open a Capital One 360 Savings Account. You can open the savings account on its own. However, you will need a way to fund it—typically by linking an external bank account or depositing a check by mobile app.

How long does it take to open the account?

The process usually takes 5 to 10 minutes online. Capital One verifies your identity and runs a soft credit check (which does not affect your credit score). Most accounts are approved and ready to use within minutes, though some applications may take up to one business day.

What if I want to close the account later?

You can close a Capital One 360 Savings Account anytime with no penalty. You can close it through the app or by calling customer service. If there is money in the account, Capital One will transfer it to the bank account you specify or mail you a check.

Can I earn interest on money I have not deposited yet?

No. Interest only accrues on money that is actually in the account. You earn nothing on a $0 balance. Once you deposit money, interest begins accruing on that balance at the rate for your balance tier.
