What an online savings account is and why the interest rate matters
An online savings account is a bank account you manage through a website or app instead of visiting a physical branch. You deposit money, it sits there earning interest, and you can withdraw it when you need it. The main reason people choose online accounts is the interest rate — the percentage the bank pays you for letting them use your money.
Banks that operate only online have lower costs than banks with buildings and staff in every neighborhood, so they pass some of those savings to you in the form of higher interest rates. A traditional bank might pay you 0.01% interest per year on savings. An online bank might pay 4% or 5% — the exact rate changes based on what the Federal Reserve does with interest rates, so it varies month to month. That difference adds up fast on larger balances.
The tradeoff is that you cannot walk into a branch and talk to someone face-to-face. Everything happens online or over the phone. For most people, this is fine. For people who prefer in-person banking or need to deposit cash regularly, it may not be the right fit.
Key Takeaways
- Online savings accounts typically offer higher interest rates than traditional banks because the bank has lower operating costs.
- You will need a government-issued ID, proof of address, and a Social Security number or ITIN to open an account.
- Deposits and withdrawals happen electronically — you link a checking account at another bank or transfer money by wire.
- Your money is insured up to $250,000 per account by the FDIC, the same protection you get at any bank.
- Most online savings accounts have no monthly fees and no minimum balance requirement, though some require you to keep a small amount on deposit.
What you need to bring to open an account
You will need three things: a government-issued photo ID (driver's license, passport, or state ID card), proof of your current address, and your Social Security number or ITIN (Individual Taxpayer Identification Number). The proof of address can be a recent utility bill, lease, mortgage statement, or bank statement — anything dated within the last 60 days with your name and address on it.
You will also need access to a computer or smartphone to complete the process online. Some banks let you upload photos of your documents; others ask you to answer security questions to verify your identity instead. The whole process usually takes 10 to 15 minutes.
If you do not have a government-issued ID, some online banks will work with you using alternative documents — call the bank's customer service line before you start the process to ask what they accept. If you do not have a Social Security number, an ITIN works the same way for account purposes.
How to move money in and out of your account
You cannot deposit cash directly into an online savings account because there is no physical location. Instead, you link a checking account at another bank — this is called an external account. You give the online bank your checking account number and routing number (a nine-digit code that identifies your bank), and they verify the link by depositing two small amounts into that checking account, usually $0.01 and $0.02. You then confirm those amounts in the online bank's app, and the link is active.
Once the link is set up, you can transfer money from your checking account to your savings account whenever you want. The transfer usually takes one to three business days. You can also transfer money back out to your checking account the same way. Some online banks let you set up automatic transfers — for example, moving $100 from checking to savings every payday.
If you need to deposit cash, you have two options: deposit it into your checking account at your regular bank, then transfer it electronically to your online savings account, or use a wire transfer. A wire transfer is faster but usually costs $15 to $25 and is best for larger amounts.
Understanding FDIC insurance and account limits
Your money in an online savings account is protected by FDIC insurance, which stands for Federal Deposit Insurance Corporation. This means if the bank fails, the government guarantees you will get your money back, up to $250,000 per account. This is the same protection you have at any bank, online or not.
The $250,000 limit applies per account at each bank. If you have $250,000 in a savings account at Bank A and $250,000 in a savings account at Bank B, both are fully protected. If you have $250,000 in a savings account and $250,000 in a money market account at the same bank, both are protected because they are different account types. But if you have two savings accounts at the same bank, the $250,000 limit covers both combined.
Most online savings accounts have no limit on how much you can deposit, and no minimum balance requirement. Some banks ask you to keep $1 or $25 on deposit to keep the account open, but this is rare. Check the specific bank's rules before you open the account.
Interest rates, fees, and what to compare
When you are looking at different online banks, compare three things: the interest rate, the monthly fee, and the minimum balance requirement. The interest rate is what the bank pays you — higher is better, but remember it changes based on Federal Reserve decisions. The monthly fee is what the bank charges you to keep the account open — most online banks charge zero. The minimum balance is the smallest amount you must keep in the account; most online banks have no minimum.
Interest rates change frequently, so do not choose a bank based on a rate you saw three months ago. Check the current rate on the bank's website the day you open the account. Some banks offer a promotional rate for the first few months, then drop it — read the fine print to see when the rate changes.
A few online banks offer tiered interest rates, which means you earn a higher percentage if you keep a larger balance. For example, you might earn 4.5% on balances up to $10,000 and 5% on balances above $10,000. If you plan to keep a large amount in savings, ask whether the bank offers tiering.
When an online savings account makes sense for you
An online savings account works well if you have money you want to keep separate from your everyday checking account and earn interest on it. It is a good fit if you are building an emergency fund, saving for a down payment, or setting aside money for a goal that is six months or more away. It is also useful if you want to reduce the temptation to spend — moving money to a separate bank makes it slightly harder to access, which can help you stick to your savings goal.
An online savings account is less useful if you need to deposit cash regularly, prefer to do all your banking in person, or want to access your money within a few days. It is also not the right choice if you need the money within three months, because the interest you earn will be small and you might find a better use for your time.
Some people use both: a checking account at a traditional bank for everyday spending and bills, and an online savings account at a different bank for goals and emergencies. This separation makes it easier to track what you are saving for and harder to accidentally spend the money.
How to choose between different online banks
Start by checking the current interest rates on a few banks' websites — Ally, Marcus, American Express Personal Savings, and Discover are common choices, but there are many others. Write down the rate, the monthly fee, and the minimum balance for each one. Then pick the bank with the highest rate and no monthly fee.
Before you open the account, read the bank's customer service reviews on independent sites like Trustpilot or the Better Business Bureau. Look for complaints about transfers taking longer than promised or difficulty reaching customer service. If a bank has many complaints about the same issue, choose a different one.
Once you have narrowed it down to one or two banks, open the account. The process takes 10 to 15 minutes, and you can close the account later if you change your mind — most online banks have no early closure fee. Start with a small deposit to make sure the transfer process works smoothly before you move a large amount.
Frequently Asked Questions
Can I use an online savings account if I do not have a checking account?
Most online banks require you to link an external checking account to move money in and out. If you do not have a checking account, you will need to open one first — at a traditional bank, credit union, or another online bank. Once you have a checking account, you can link it to your savings account and transfer money between them.
How long does it take to transfer money out of an online savings account?
Electronic transfers between your online savings account and a linked checking account usually take one to three business days. Weekends and holidays do not count as business days. If you need the money faster, you can request a wire transfer, which usually arrives the same day or next business day, but most banks charge $15 to $25 for this service.
What happens if the online bank goes out of business?
The FDIC protects your money up to $250,000. If the bank fails, the FDIC will either transfer your account to another bank or send you a check for your balance. You do not need to do anything — the FDIC handles it automatically. Your money is safe even if the bank disappears.
Can I have multiple online savings accounts at different banks?
Yes. You can open savings accounts at as many banks as you want. Each account is insured separately up to $250,000 by the FDIC. Some people open multiple accounts to earn different interest rates or to keep money separated by goal — one account for emergencies, one for a vacation, one for a car down payment.
Do I need to report online savings account interest on my taxes?
Yes. The bank will send you a Form 1099-INT at the end of the year showing how much interest you earned. You report this on your tax return. If you earned less than $10 in interest, the bank may not send a form, but you still need to report it if you file taxes. Keep your own records of interest earned throughout the year.
