What an online savings account is

An online savings account is a bank account you open and manage entirely through a website or mobile app, with no physical branch to visit. The bank holds your money and pays you interest on the balance. You can deposit funds by transferring from another bank account, and you can withdraw money the same way — but most online banks limit you to six withdrawals per month (a federal rule that has exceptions).

The main difference from a traditional bank account is that online banks have lower overhead costs, so they typically pay higher interest rates on savings. A brick-and-mortar bank might pay 0.01% annual interest; an online savings account often pays between 4% and 5%, depending on the current market and the bank. That difference compounds over time, especially if you keep money in the account for months or years.

Your deposits are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per account holder per bank. This means if the bank fails, the government guarantees your money back up to that limit.

Key Takeaways

  • Online savings accounts pay significantly higher interest rates than traditional bank accounts because the bank has lower operating costs.
  • You manage the account entirely online or through an app — there is no physical branch and no debit card for everyday spending.
  • Federal law limits you to six withdrawals per month, though some banks have removed this cap.
  • Your deposits are FDIC-insured up to $250,000, the same protection as a traditional bank account.
  • Opening an account takes minutes and usually requires only an email address, Social Security number, and initial deposit.

How deposits and withdrawals work

To put money into an online savings account, you link it to a checking account at another bank. You then transfer funds from that checking account to your savings account through the online bank's website or app. The transfer typically takes one to three business days. Some online banks also accept direct deposit from your employer, which lands in the account on payday.

To withdraw money, you reverse the process: initiate a transfer from the savings account back to your linked checking account. Again, this takes one to three business days. You cannot write checks against a savings account, and most online banks do not issue debit cards, so you cannot swipe the card at a store. The account is designed for money you want to keep separate and untouched.

The six-withdrawal limit exists because savings accounts are legally classified differently from checking accounts. However, many online banks have stopped enforcing this limit, especially after the Federal Reserve suspended the rule in 2020. Check your bank's current policy before opening an account if frequent withdrawals matter to you.

Interest rates and how they change

When you open an online savings account, the bank tells you the current annual percentage yield (APY) — the interest rate you will earn on your balance over one year. If the account offers 4.5% APY and you keep $10,000 in it for a full year with no deposits or withdrawals, you will earn $450 in interest.

Interest rates change constantly because they follow the federal funds rate set by the Federal Reserve. When the Fed raises rates, online banks typically raise their savings rates within days or weeks. When the Fed cuts rates, online banks cut their rates too. You do not have to do anything — the rate simply changes on your account. Some banks notify you by email when a rate change happens; others do not.

The rate you see advertised is only may provide for the day you open the account. After that, the bank can lower the rate whenever it wants. This is normal and legal. If you want to lock in a higher rate for a longer period, you would open a certificate of deposit (CD) instead, which is a different product with a fixed rate for a set term.

Fees and minimum balances

Most online savings accounts charge no monthly maintenance fee, no overdraft fee, and no minimum balance requirement. This is one of their main advantages over traditional banks, which often charge $5 to $15 per month if your balance falls below a threshold.

Some online banks do charge fees in specific situations: if you exceed the six-withdrawal limit in a month, if you close the account within a certain period (usually 90 days), or if you initiate a wire transfer. Read the fee schedule before opening an account. Many banks publish this information in a document called the "Deposit Account Agreement" or "Schedule of Fees."

A few online banks offer premium savings accounts with higher interest rates in exchange for maintaining a larger minimum balance — often $25,000 or more. These are worth considering only if you have that much money sitting idle and want to maximize interest earned.

How to open an account

Opening an online savings account takes 10 to 15 minutes and requires no paperwork mailed by post. You visit the bank's website, click "Open an Account," and provide your name, address, date of birth, and Social Security number. The bank verifies your identity instantly using a database check.

You then choose how much to deposit to start. Most online banks require a minimum opening deposit of $0 to $25, though some waive the minimum entirely. You fund this deposit by linking a checking account at another bank and transferring money, or by providing your bank routing and account number so the bank can pull the funds directly.

Once the initial deposit clears (usually one to three business days), your account is active and earning interest. You can log in immediately to see your balance and set up automatic transfers, but you may not be able to withdraw until the deposit has fully cleared.

Online savings accounts versus money market accounts

A money market account is similar to a savings account but usually offers a higher interest rate in exchange for a larger minimum balance (often $2,500 or more). Money market accounts also come with a debit card and checkbook, so you can access your money more easily — but this flexibility sometimes comes with a lower interest rate than a dedicated savings account at the same bank.

If you want to park money and leave it untouched, an online savings account is simpler and often pays more. If you want occasional access without transferring to another account, a money market account may be worth the higher minimum. Compare the rates and features at your chosen bank before deciding.

Another alternative is a high-yield checking account, which some online banks offer. These pay interest rates comparable to savings accounts but let you write checks and use a debit card. However, they often require a larger minimum balance or a monthly direct deposit to may have access to for the top rate.

Safety and FDIC insurance

Online banks are regulated by the same federal agencies as traditional banks — usually the Office of the Comptroller of the Currency (OCC) or the Federal Reserve. They must follow the same rules about how they hold and invest your money. The fact that you cannot walk into a branch does not make the bank less safe.

Your deposits are insured by the FDIC up to $250,000 per account holder per bank. This means if the bank fails, the FDIC will return your money. If you have more than $250,000, you can open accounts at multiple banks to spread the risk — each bank's account is insured separately.

To verify that a bank is FDIC-insured, visit the FDIC's website and search the bank's name in their "Bank Find" tool. This takes 30 seconds and confirms the bank is legitimate and your money is protected.

Frequently Asked Questions

Can I use an online savings account as my main checking account?

No. Savings accounts do not come with debit cards or checkbooks, and you cannot make purchases with them. They are designed to hold money you want to keep separate. You need a checking account (online or traditional) for everyday spending, and a savings account to earn interest on money you are not using right now.

What happens if I exceed the six-withdrawal limit?

Many banks no longer enforce this limit, but some still do. If your bank enforces it and you exceed six withdrawals in a month, the bank may charge a fee (usually $10), convert your account to a checking account, or close the account. Check your bank's policy before opening an account if you think you will need frequent withdrawals.

How long does it take to transfer money out of an online savings account?

Standard transfers between your online savings account and a linked checking account take one to three business days. Some banks offer faster transfers for an extra fee, but most people do not need this. Plan ahead if you know you will need the money on a specific date.

Do I pay taxes on the interest I earn?

Yes. Interest earned in a savings account is taxable income. At the end of each year, the bank sends you a Form 1099-INT showing how much interest you earned. You report this on your tax return. The bank does not withhold taxes automatically, so you may owe money when you file.

Can I open multiple online savings accounts?

Yes. You can open accounts at different banks to spread your money across multiple FDIC-insured accounts, each protected up to $250,000. Some people do this to maximize interest rates or to keep money organized for different goals. There is no limit on how many accounts you can open.
