Jump to our picks for the Best Online Banks:

Online banks and banking service providers offer desktop and mobile banking services without physical branches. Because online institutions don’t have to pay for the cost of maintaining branches, they're often able to pass the savings on to their customers in the form of higher interest rates. Online banks require customers to be comfortable with technology, but they also tend to provide robust customer service options to help users resolve any issues.

NerdWallet’s picks include online banks, nonbanks and credit unions. Some of these financial institutions are not themselves chartered banks, as noted in their descriptions.

Our picks for banks with checking and savings accounts


Chime Overall Bank Rating
NerdWallet rating 

at Chime, Deposits are FDIC Insured

Chime gives customers free access to more than 60,000 ATMs, but for out-of-network ATMs, it charges $2.50 per transaction. Chime customers must visit a Green Dot location in order to deposit cash, and they may be charged a fee to do so. Chime also allows customers to receive their pay up to two days early via direct deposit (see below for more information from Chime). Chime’s mobile app ratings from customers are high in Apple’s App Store and the Google Play store.

Chime is not a chartered bank; Chime works with Federal Deposit Insurance Corp.-insured banks behind the scenes so that customer funds can be insured. See below for more information from Chime.

Chime says: "Early Access to direct deposit funds depends on payer."

"Chime is a financial technology company, not a bank. Banking services provided by, and debit card issued by, The Bancorp Bank or Stride Bank, N.A.; Members FDIC."


LendingClub Overall Bank Rating

LendingClub’s checking account has cash-back rewards and earns a bit of interest, and customers can access thousands of ATMs in the MoneyPass and SUM networks. LendingClub also has no cap on ATM fee refunds for customers who use ATMs that are out of network.

LendingClub’s savings account earns an interest rate of 0.60% APY. Its app has good reviews in both the Apple App Store and the Google Play store.

Discover also offers more than 60,000 fee-free ATMs, and Discover’s mobile banking apps have high ratings from customers.

Alliant Credit Union

Alliant Credit Union High-Rate Checking
NerdWallet rating 

at Alliant Credit Union, Federally insured by the NCUA

Alliant offers a 0.55% APY on its High-Rate Savings account, a rate much higher than the average 0.06% APY offered on savings accounts at traditional banks. Alliant also offers a High-Rate Checking account with a 0.25% APY, and share certificates (the credit union equivalent of certificates of deposit) with above-average rates.

If you don’t qualify for Alliant membership based on Alliant’s general requirements, you can do so by becoming a member of the charity Foster Care to Success; Alliant will pay the $5 membership fee on your behalf.


Varo Overall Star Rating
NerdWallet rating 

at Varo, Member FDIC

Varo offers a checking and savings account, but it doesn’t offer certificates of deposit. Its savings account comes with a baseline 0.50% annual percentage yield, but that interest rate becomes 3.00% if customers meet some monthly requirements: receive $1,000 or more in direct deposit, have a monthly savings balance below $5,000 and have a checking and savings balance of more than $0.

There are limits and fees for cash deposits, and the only way a Varo customer can deposit cash is by going to a third-party retailer that participates in the Green Dot network, like 7-Eleven, CVS and Walgreens.

To withdraw cash, customers can use an ATM in the Allpoint network for free; use of non-Allpoint ATMs carries a $2.50 fee from Varo in addition to any fees that the ATM owner may charge.


Nationwide Overall Bank Rating
NerdWallet rating 

at Nationwide

Banking service provider Nationwide’s deposit accounts are serviced by Axos Bank and are therefore covered by FDIC insurance. Its Advantage Checking account earns an interest rate of 0.45% APY if you either set up direct deposits of $1,000 or more per month or make at least 10 transactions of $3 or more. If you meet both requirements, you can earn up to 0.90% on your checking account.

Nationwide’s My Savings account earns up to a 0.30% APY, but its certificates of deposit have rates that are lower than what you’d find at other financial institutions. Its apps have high ratings from customers, and its customer phone support is available 24/7 except for Thanksgiving and Christmas.

TAB Bank

TAB Bank Overall Bank Rating
NerdWallet rating 
Read review

TAB Bank’s Cash Back Checking account allows customers to earn 1% on monthly purchases with no cap on earnings, and the bank refunds up to $15 monthly in ATM fees. To qualify for these benefits, customers must make at least 15 transactions per month with a minimum of $5 per transaction, and there must be at least one direct deposit, bill pay transaction or fund transfer monthly.

TAB Bank’s High-Yield Savings earns a 0.50% APY, and its certificates of deposit also have solid, competitive rates. The bank has a highly rated mobile app that allows customers to manage their account and has standard features like mobile check deposit.

NerdWallet rating 
Read review

Ally Bank’s savings account offers a 0.50% APY, its checking account earns 0.10% APY for balances under $15,000, and it earns 0.25% for balances of $15,000 or more. Its certificates of deposit have competitive rates as well. Ally doesn’t allow customers to deposit cash; accounts must be funded by transfers from an external account, depositing a check via mobile or mail, or using a wire transfer.

Ally’s phone support is available 24/7, and its website has a chat feature to help customers.

Of note: You must have a balance of at least $10,000 in the savings account and at least $25,000 in the money market account to earn the highest APY, and the money market account charges a monthly fee if your balance falls below $5,000.

NerdWallet rating 
Read review

Our picks for banks with checking accounts only


GoBank Overall Bank Rating
NerdWallet rating 
Read review

GoBank, a banking services provider backed by Green Dot Bank, doesn’t have a savings account or certificates of deposit, but it has a checking account with a large ATM network. GoBank’s early direct deposit service can get customers their paychecks two days in advance. A monthly fee can be avoided with direct deposits of at least $500 per month.

A notable feature at GoBank is that it doesn’t implement a credit check or use ChexSystems, the consumer reporting agency that tracks account misuse. That means if you have a blemished banking record, GoBank may be able to help you get back on track. GoBank’s customer service is available by phone and online chat, and its app has received high ratings from users on iOS and Android.

Frequently asked questions

An online bank is a financial institution that operates without any physical branches. Such banks typically have strong mobile apps and customer service options, as well as higher interest rates than traditional brick-and-mortar banks.

It varies. If the bank is part of an ATM network, you can likely use an ATM to either deposit or withdraw cash; some online banks only allow online transfers in and out of the account. Online banks also usually allow mobile check deposits, direct deposit from employers and online transfers to and from external bank accounts.

Both traditional and online banks typically allow people to apply for accounts online these days. It can take just a few minutes and typically involves creating a username and password and entering some personal information. See NerdWallet’s guide to how to open an account online.

Online banks are typically safe. Most banks use data encryption, and some allow customers to opt in to two-factor authentication when logging in to their accounts. Customers should also take care to practice good security hygiene when it comes to banking online.

Chartered banks are FDIC insured — meaning if the bank goes out of business, then your money is federally protected, usually up to $250,000 — but some online financial institutions are not themselves chartered banks. In those cases, the financial institution typically partners with a chartered bank behind the scenes to provide FDIC insurance to customers.
