Online banks are financial institutions that operate entirely through the internet, with no physical branches

An online bank is a company licensed to hold deposits and make loans, just like a traditional bank, but it conducts all business through a website or mobile app instead of a building you can walk into. You open an account online, deposit money electronically, pay bills through the app, and transfer funds between accounts without ever speaking to someone in person. The bank's costs are lower because it has no branch network to maintain, and it typically passes some of those savings to customers through higher interest rates on savings accounts or lower fees on checking accounts.

Online banks are regulated by the same federal agencies that oversee traditional banks — the Office of the Comptroller of the Currency (OCC), the Federal Deposit Insurance Corporation (FDIC), or the National Credit Union Administration (NCUA), depending on the bank's charter type. Your deposits are insured up to $250,000 per account category, the same as money in a brick-and-mortar bank. The main trade-off is convenience: you cannot hand a teller a check or ask someone face-to-face how to fix a problem, though most online banks offer phone support and live chat.

Key Takeaways

  • Online banks hold your money and are insured by the FDIC or NCUA, so your deposits are protected the same way as at a traditional bank.
  • You manage everything through an app or website — there are no physical locations to visit and no tellers to speak with in person.
  • Online banks typically offer higher interest rates on savings accounts and lower or no monthly fees because they have lower operating costs.
  • Most online banks offer phone support and live chat, but response times may be slower than walking into a branch during business hours.
  • Some online banks are standalone institutions, while others are divisions of larger traditional banks that also operate physical branches.

How deposits and withdrawals work at an online bank

When you open an account at an online bank, you fund it by transferring money from another bank account you already have. This happens through the Automated Clearing House (ACH), a network that moves money between banks electronically. You provide your existing bank's routing number and account number, and the online bank initiates the transfer. The money typically arrives within one to three business days.

To withdraw money, you can transfer it back to your original bank account the same way, or you can use the online bank's ATM network. Many online banks partner with ATM networks so you can withdraw cash at thousands of locations without paying a fee. Some reimburse you for out-of-network ATM fees if you use an ATM that is not part of their network. A few online banks also issue debit cards that work at any ATM, though not all do.

Depositing checks works differently than at a traditional bank. Most online banks let you photograph the front and back of a check using their mobile app, a process called mobile check deposit. The image is transmitted to the bank, which processes it electronically. The check clears within one to five business days, depending on the amount and the bank's policies. Some online banks do not accept checks at all, so this is worth confirming before you open an account if you receive checks regularly.

Interest rates and fees at online banks

Online banks typically offer higher interest rates on savings accounts and money market accounts than traditional banks because their lower overhead costs allow them to pay more. The rate varies by bank and changes based on the Federal Reserve's interest rate decisions. When the Fed raises rates, online banks usually raise their savings rates quickly. When the Fed cuts rates, online banks cut theirs as well, though sometimes more slowly.

Many online banks charge no monthly maintenance fee on checking or savings accounts, and some waive overdraft fees or offer overdraft protection. A few charge a small monthly fee but offset it with higher interest rates. Read the fee schedule before opening an account — it is usually listed on the bank's website under "Pricing" or "Fees and Rates."

Online banks typically do not charge fees for transfers between your own accounts, wire transfers initiated by you, or bill payments through their platform. Some charge a fee if you need the bank to send you a wire transfer, or if you use an out-of-network ATM and the bank does not reimburse the fee. Again, the specifics vary by bank.

The difference between online banks and traditional banks

A traditional bank has physical locations where you can deposit cash, withdraw money, and speak with a banker about loans or account issues. An online bank has none of this. You cannot walk in, hand someone a check, or sit down to discuss a mortgage process. Everything happens remotely.

Traditional banks often charge monthly maintenance fees, require minimum balances, and pay lower interest rates on savings accounts. They also typically have longer hours — a branch might be open until 6 p.m. on weekdays and a few hours on Saturday, but an online bank's website and app are available 24/7. Customer support at an online bank is usually available by phone or chat during business hours, not in person.

For some people, the lack of a physical location is a dealbreaker. If you deposit cash regularly, need to speak with someone in person, or prefer the security of a building you can visit, a traditional bank may suit you better. For others, the higher interest rates and lower fees make the trade-off worthwhile.

Online banks versus online-only divisions of traditional banks

Some online banks are independent companies with no physical branches at all — examples include Ally Bank, Marcus by Goldman Sachs, and Discover Bank. Others are online divisions of large traditional banks. For instance, Bank of America has an online banking platform, and so does Wells Fargo, but both also operate thousands of physical branches.

The difference matters if you value having a branch nearby. If you bank with an online division of a traditional bank, you can visit a physical location if you need to, though you may not be able to access your online account there without calling ahead. If you bank with a fully online institution, there is no branch to visit — you are entirely dependent on phone, chat, and the app.

Both types are regulated the same way and both offer FDIC insurance. The choice comes down to whether you want the option of a physical location, and whether the online bank's rates and features meet your needs.

Security and fraud protection at online banks

Online banks use encryption to protect your login credentials and account information when you access your account through their website or app. This is the same technology that protects your information when you shop online or check email. Your data is encrypted both when it travels to the bank's servers and when it sits in their systems.

Most online banks offer two-factor authentication, which means you need both your password and a second form of verification — usually a code sent to your phone — to log in. This makes it much harder for someone to access your account even if they steal your password.

If someone fraudulently transfers money out of your account, federal law limits your liability. If you report the fraud within two business days, you are liable for no more than $50 of unauthorized transfers. If you wait longer, your liability can be higher. Online banks typically have fraud monitoring systems that flag unusual activity and contact you to confirm it is legitimate.

How to choose an online bank

Start by deciding what you need the account for. If you want a checking account for everyday spending, look for a bank with no monthly fee, no minimum balance requirement, and a debit card. If you want a savings account to earn interest, compare the interest rates across several banks — the difference between a 4.5% rate and a 5.0% rate adds up over time.

Check whether the bank's ATM network covers locations where you live and work. If you travel frequently or live in a rural area, this matters more. Look at the bank's customer support options — does it offer phone support during hours when you are awake? Does it have live chat? Read recent customer reviews on independent sites to see what problems people have encountered.

Verify that the bank is FDIC-insured or NCUA-insured by checking the FDIC's or NCUA's website. This takes two minutes and is the most important step. If the bank is not insured, your deposits are not protected if the bank fails.

Frequently Asked Questions

Is my money safe at an online bank?

Yes, if the bank is FDIC-insured or NCUA-insured. Your deposits are protected up to $250,000 per account category, the same as at a traditional bank. You can verify the bank's insurance status on the FDIC or NCUA website before you open an account.

Can I deposit cash at an online bank?

Most online banks do not accept cash deposits directly. You can deposit checks through mobile check deposit, and you can transfer money from another bank account. A few online banks partner with retailers like Walmart or CVS to accept cash deposits, but this is uncommon. Check the bank's website to see what deposit methods it offers.

What happens if I need to speak with someone?

Most online banks offer phone support during business hours, usually 8 a.m. to 8 p.m. or 9 a.m. to 9 p.m. on weekdays, with limited hours on weekends. Many also offer live chat through their website or app. Response times are usually faster for chat than for phone, but slower than walking into a branch.

Do online banks offer loans or credit cards?

Some do and some do not. Many online banks offer personal loans and credit cards, while others focus only on deposit accounts like checking and savings. Check the bank's website to see what products it offers. If you need a mortgage or auto loan, some online banks offer these, but you will complete the entire process remotely.

Can I switch from a traditional bank to an online bank?

Yes. Most online banks have a process to transfer your direct deposits and automatic bill payments from your old bank. You can also transfer your existing balance by moving money from your old account to your new one. Close your old account once everything has moved over, though you may want to keep it open for a month to make sure nothing is still trying to use it.
