What an online bank is and how it differs from a traditional bank
An online bank is a financial institution that operates entirely or almost entirely through the internet, with no physical branches you can walk into. You open an account, deposit money, transfer funds, pay bills, and manage your account through a website or mobile app. Most online banks are FDIC-insured, meaning your deposits up to $250,000 are protected the same way they are at a brick-and-mortar bank.
The main difference between an online bank and a traditional bank is overhead. A traditional bank pays for building leases, tellers, security, and branch staff. An online bank does not. That lower cost structure is why online banks typically offer higher interest rates on savings accounts and checking accounts, and charge fewer or no monthly fees. The trade-off is that you cannot walk in and speak to someone in person, and you cannot deposit cash directly at a branch.
Some banks are online-only — they have no physical locations at all. Others are hybrid: they are primarily online but operate a few branches or partner with ATM networks so you can withdraw cash. A few traditional banks also offer online-only accounts alongside their branch services.
Key Takeaways
- Online banks charge lower fees and pay higher interest rates than traditional banks because they have no physical branches to maintain.
- Your money is protected by FDIC insurance at most online banks, just as it is at a traditional bank, up to $250,000 per account type.
- You cannot deposit cash directly at most online banks, so you will need to use ATM networks, transfers from other accounts, or mobile check deposit.
- Online banks are regulated by the same federal agencies as traditional banks, but customer service is available only by phone, email, or chat — never in person.
How to deposit and withdraw money at an online bank
Depositing money at an online bank depends on the type of account and the bank's partnerships. Most online banks let you deposit checks using a mobile app — you photograph the front and back of the check and submit it. The bank then transfers the funds to your account, usually within one to three business days. Some banks also accept wire transfers from other accounts, ACH transfers (which are slower but free), and direct deposit from an employer or government program.
Cash deposits are the main limitation. Most online banks do not accept cash directly. If you need to deposit cash, you have a few options: use an ATM at a partner bank or ATM network (some online banks partner with networks like Allpoint or MoneyPass), transfer cash to someone else's account at a traditional bank and have them send it to you, or withdraw cash from a traditional bank account and transfer it electronically. Some online banks have partnerships with retail chains like Walmart or CVS where you can deposit cash at the register.
Withdrawing money is straightforward. You can use ATMs at partner locations, transfer money to another bank account, or request a check by mail. Most online banks do not charge ATM fees if you use their partner network, though out-of-network ATM fees may apply.
Interest rates and fees at online banks
Online banks typically offer higher interest rates on savings accounts and money market accounts than traditional banks. The rate varies by bank and changes based on the Federal Reserve's interest rate decisions. When rates are high, online banks pass more of that to customers. When rates drop, so do the rates they offer. You should check the current rate at the specific bank you are considering, because rates change frequently and differ significantly between institutions.
Monthly maintenance fees are rare at online banks. Most charge nothing to hold a checking or savings account. Some online banks do charge fees for overdrafts, wire transfers, or expedited check processing, but these are optional services — you only pay if you use them. A few online banks charge a monthly fee if your balance falls below a minimum, but many have no minimum balance requirement at all.
The cost advantage of an online bank is real, but only if you do not need cash deposits often and do not require in-person customer service. If you regularly deposit cash or need to speak to someone face-to-face, a traditional bank or a hybrid bank may be worth the lower interest rate and higher fees.
FDIC insurance and account protection at online banks
Most online banks are FDIC-insured, which means the Federal Deposit Insurance Corporation protects your money if the bank fails. The protection covers up to $250,000 per depositor, per bank, per account type. So if you have $250,000 in a checking account and $250,000 in a savings account at the same online bank, both are fully protected — they are different account types. If you have two savings accounts at the same bank, the $250,000 limit applies to the combined total across both accounts.
Before you open an account, check whether the bank is FDIC-insured. The bank's website will state this clearly, usually at the bottom of the page. You can also search the FDIC's bank database online to confirm. A very small number of online banks are not FDIC-insured — these are riskier and generally not worth the risk.
FDIC insurance does not protect you from fraud or theft. If someone steals your login credentials and drains your account, FDIC insurance does not cover it. However, federal law limits your liability for unauthorized transactions if you report them promptly. Most online banks also offer fraud monitoring and will reverse unauthorized charges if you report them within a reasonable time frame.
Customer service and support at online banks
Online banks do not have branch staff, so customer service is handled by phone, email, live chat, or sometimes social media. Most online banks offer phone support during business hours — some 24/7, others only during weekday hours. Response times for email and chat vary by bank, but most aim to respond within a few hours during business hours.
The quality of customer service at online banks is mixed. Some are known for fast, helpful support. Others have longer wait times and less experienced representatives. Before you open an account, read recent customer reviews on independent sites to get a sense of how the bank handles problems. If you know you will need frequent support, a traditional bank or a hybrid bank may be a better fit.
Online banks typically do not have the ability to resolve complex problems in real time the way a branch can. If you need to dispute a transaction, report fraud, or handle an unusual situation, the process may take longer than it would at a traditional bank.
Types of accounts available at online banks
Most online banks offer checking accounts, savings accounts, and money market accounts. Some also offer certificates of deposit (CDs), which lock your money away for a set period in exchange for a higher interest rate. A few online banks offer other products like personal loans or investment accounts, though most focus on deposit accounts.
Checking accounts at online banks work like checking accounts anywhere else — you get a debit card, can write checks, and can set up automatic bill payments. Savings accounts earn interest and typically limit you to a certain number of withdrawals per month (though this rule is less strictly enforced than it once was). Money market accounts are a hybrid: they earn interest like a savings account but come with a debit card and checkbook like a checking account, though they usually require a higher minimum balance.
The specific features and interest rates vary by bank and change over time. When you are comparing online banks, look at the account types they offer and whether those match what you need.
How to choose an online bank
Start by deciding what you need. Do you deposit cash regularly? If so, an online-only bank may not work for you — look for a hybrid bank or a traditional bank instead. Do you want the highest interest rate possible? Online banks usually win here. Do you need strong customer service? Read reviews and check whether the bank offers phone support during hours when you are awake.
Next, compare the specific accounts and rates. Visit the websites of two or three online banks and note the interest rate on their savings account, any monthly fees, minimum balance requirements, and what ATM networks they partner with. Rates change frequently, so do this comparison close to when you plan to open the account.
Finally, check that the bank is FDIC-insured and read a few recent customer reviews. Look for complaints about specific problems — fraud resolution, deposit delays, account closures — rather than general complaints about not having branches. Once you have chosen a bank, opening an account is usually quick and can be done entirely online.
Frequently Asked Questions
Is my money safe at an online bank?
Yes, if the bank is FDIC-insured. Your deposits are protected up to $250,000 per account type, the same as at a traditional bank. Check the bank's website to confirm FDIC insurance before you open an account. Fraud and theft are separate issues — report unauthorized transactions promptly to limit your liability.
How long does it take to transfer money from an online bank to another bank?
ACH transfers (the standard method) usually take one to three business days. Wire transfers are faster — often same-day or next-day — but many online banks charge a fee for them. Check your specific bank's transfer times and fees before you need to move money urgently.
Can I use my debit card at any ATM if I bank online?
Most online banks partner with ATM networks, so you can withdraw cash at partner ATMs for free. Out-of-network ATMs may charge a fee. Check which ATM network your online bank partners with and whether there are locations near your home or work before you open an account.
What happens if an online bank goes out of business?
The FDIC steps in and protects your deposits up to $250,000 per account type. Your money is transferred to another FDIC-insured bank, and you can access it within a few days. This has happened only rarely in recent years, and FDIC protection makes it safe.
Do online banks report to credit bureaus?
Online banks report checking and savings account activity to credit bureaus only if you miss payments or overdraft significantly. Opening a savings account does not build credit. If you want to build credit, you need a credit card, loan, or other credit product — not just a bank account.
