There is no single "best" online bank—the right choice depends on what you do with your money

Online banks differ in what they charge, what they pay you, and what features they offer. One bank might have the highest savings rate but charge fees for transfers. Another might have no fees but pay almost nothing on deposits. The "best" bank is the one that matches how you actually use money: whether you need to deposit checks by phone, whether you move money between accounts often, whether you keep a small balance or a large one, and whether you want customer service by phone or chat.

This guide walks you through what to compare, what the real trade-offs are, and how to read the fine print so you know what you are actually getting before you open an account.

Key Takeaways

  • Online banks typically offer higher savings rates than brick-and-mortar banks because they have lower overhead, but rates change monthly and vary by bank.
  • Monthly fees, transfer limits, and minimum balance requirements differ widely—read the fee schedule before opening an account, not after.
  • Some online banks let you deposit checks by phone camera, while others require you to mail them in or use a partner bank's ATM.
  • Customer service availability (phone, chat, email) and response time matter most if you need to resolve a problem quickly.
  • Your money is insured the same way at an online bank as at any other bank—up to $250,000 per account type through FDIC insurance.

How to compare savings rates and what they actually mean

Online banks advertise savings rates that are often two to five times higher than traditional banks. A rate of 4.50% annual percentage yield (APY) means that if you keep $10,000 in the account for a full year with no deposits or withdrawals, you will earn $450 in interest. But that rate is only may provide for the period the bank states—usually one statement cycle. Banks can and do lower rates when the Federal Reserve cuts rates, sometimes within days.

When you compare banks, look at the current rate for the account type you want (savings, money market, or checking), not the rate from last month or the rate the bank advertises on its homepage. Most banks show the current rate on the account details page or in the terms and conditions. Write down the rates from three to five banks you are considering, then check them again one week later to see which ones are stable and which ones move frequently. A bank that cuts rates every month is not necessarily worse—it may just be more responsive to market changes—but you should know what to expect.

Fees that matter and fees that don't

Most online banks charge no monthly maintenance fee, but some charge fees for specific actions. The fees that affect most people are overdraft fees (charged when you spend more than you have), wire transfer fees (charged to send money outside the bank), and ATM fees (charged when you use an ATM that is not part of the bank's network). Some banks reimburse ATM fees; others do not. Some charge $0 to wire money; others charge $15 to $25 per wire.

Read the fee schedule on the bank's website before you open an account. Look specifically for: monthly maintenance fees, overdraft fees, insufficient funds fees, wire transfer fees (both incoming and outgoing), ACH transfer fees, and ATM fees. If the bank does not list a fee, call or chat and ask directly. Banks are required to disclose fees, but they do not always make them straightforward to find. If a bank charges $35 per overdraft and you overdraft twice a month, that is $840 a year—more than the difference in interest rates between banks.

How to deposit checks and withdraw cash

Online banks have no physical branches, so you cannot walk in and deposit a check. Most online banks offer one or more of these options: mobile check deposit (photograph the check with your phone and submit it through the app), mail-in deposit (the bank sends you an envelope), or partnership with another bank's ATM network (you can deposit at a partner branch). Some banks offer all three; others offer only one.

If you receive checks regularly—paychecks, rent payments, insurance reimbursements—mobile check deposit is the fastest option. Most banks process mobile deposits within one to two business days. If you rarely receive checks, mail-in deposit is fine, though it takes five to seven business days. For cash withdrawals, check whether the bank has a surcharge-free ATM network. Some online banks partner with networks like Allpoint or MoneyPass, which have thousands of ATMs nationwide. Others have no ATM network and charge you $2 to $3 per withdrawal at out-of-network ATMs.

Customer service: when you need help and how fast you can get it

Online banks offer customer service through chat, email, and sometimes phone. Chat is usually the fastest—most banks respond within minutes during business hours. Phone support is available at some banks but not all; if phone support matters to you, confirm the bank offers it before you open an account. Email is slowest, typically taking 24 to 48 hours for a response.

If you have a problem—a fraudulent transaction, a missing deposit, a question about a fee—the speed of support matters. A bank with 24/7 chat support can help you on a Sunday night. A bank with email-only support cannot. Check the bank's website for the hours of operation for each support channel. Some banks offer phone support only during business hours but chat support around the clock. If you work nights or weekends, that matters.

FDIC insurance and what happens if the bank fails

Your money at an online bank is insured the same way as money at a traditional bank. The Federal Deposit Insurance Corporation (FDIC) insures deposits up to $250,000 per depositor, per bank, per account type. That means if you have a savings account and a checking account at the same bank, each is insured separately up to $250,000. If you have $300,000 in savings at one bank, $250,000 is insured and $50,000 is not.

Most online banks are FDIC-insured. Before you open an account, confirm the bank's FDIC status on the FDIC's website (search for the bank by name). If a bank is not FDIC-insured, your money has no federal protection if the bank fails. This is rare—most online banks are insured—but it is worth checking.

What to do before you open an account

Make a list of what matters most to you: the interest rate, the monthly fee, the ability to deposit checks by phone, the availability of phone support, or the ATM network. Then visit the websites of three to five banks and write down the current rate, the fees, and the deposit and withdrawal options for each. Open an account at the bank that best matches your priorities, not the bank with the highest advertised rate.

When you open an account, you will need to provide your Social Security number, a government-issued ID, your address, and your phone number. The process usually takes 10 to 15 minutes online. Some banks require a minimum opening deposit (often $0 to $25); others do not. After you open the account, set up direct deposit or a transfer from your current bank so money reaches your new account. Most banks take one to three business days to process transfers.

Frequently Asked Questions

Can I move my money out of an online bank if I change my mind?

Yes. You can transfer money out to another bank at any time, usually within one to three business days. There is no penalty for closing an account. If you have automatic payments set up (like a bill payment), cancel them before you close the account so they do not bounce.

What if I need to deposit cash?

Most online banks do not accept cash deposits directly. Some partner banks allow you to deposit cash at their branches and transfer it to your online bank account. Others do not. If you receive cash regularly, ask the bank about cash deposit options before you open an account. A traditional bank or credit union may be a better fit if cash deposits are important to you.

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. Online banks use the same security standards as traditional banks—encryption, fraud monitoring, and two-factor authentication. Confirm the bank is FDIC-insured before you open an account by checking the FDIC's website.

Do online banks report to credit bureaus?

Most online banks do not report checking or savings account activity to credit bureaus because those accounts do not involve credit. If you use a debit card from an online bank, that activity is not reported either. Only credit products (credit cards, loans) are reported to credit bureaus.

What happens to my account if the bank is sold or merges with another bank?

Your account transfers to the new bank automatically. Your money remains insured, and your account number usually stays the same. The new bank will notify you of any changes to fees, rates, or terms. You can close the account and move your money if you do not like the changes.
