Discover doesn’t charge monthly fees on any of its accounts. It has done away with insufficient funds and overdraft fees for the Discover Bank Cashback Debit, Online Savings, and Money Market accounts.
Discover scored the maximum points in our security category. Customers who place a premium on account protection can opt into alerts for suspicious activity. What’s more — there’s a $0 fraud liability guarantee, so you’re never on the hook for fraudulent credit card purchases.

Best for fee transparency and customer service
Ally Bank is an online bank headquartered in Utah that offers a range of personal banking and retirement products, as well as lending and investment services.

Ally is a viable option for customers who prefer to use one bank for all of their accounts. It offers fee-free checking and savings accounts as well as credit card and other financing options.
Another key factor: Ally offers 24/7 support via telephone and chat for customers who value the ability to speak to a live banking specialist.
Ally Bank’s products:
Checking account: Ally’s Spending Account is a fee-free checking account option that lets users organize their cash into spending buckets, deposit checks remotely, and even get access to their paycheck up to two days earlier than their payday.

Best for a wide range of savings options

Quontic offers a suite of traditional mortgages, such as conventional and FHA loans, as well as non-traditional mortgages such as bank statement loans and foreign national loans. Quontic also offers mortgage refinancing for current homeowners.
While Quontic fell behind some of the other banks on our list for having fewer banking products, it stands out for its large ATM network of about 91,000 fee-free ATMS. It also offers a wide range of CD terms for short-term and long-term savings goals. Additionally, its mobile banking app averaged an almost perfect score on both the Apple App Store and Google Play storefronts.
Quontic’s online and mobile banking platform allows users to deposit checks remotely, round up their savings, automatically pay bills, lock and unlock debit cards, transfer funds between accounts, and more.
Quontic also earned a high score in the customer service department, offering customers three different ways to contact a customer service representative – phone, email, and chat.
Quontic Bank’s products:
Checking accounts: Quontic offers a high-interest checking account for consumers who want to earn interest on their balance, as well as a rewards checking account that allows customers to earn cash back on debit card purchases. A standout product is Quontic’s innovative Pay Ring. If you’re the kind of customer who sometimes forgets your wallet at home, this is a wearable ring that ensures that you always have access to your funds and can pay for a purchase by tapping your ring at the checkout counter.
Savings account: Quontic’s high-yield savings account compounds interest daily and requires $100 to get started.
Certificates of deposit: Quontic offers several certificates of deposit, with terms that range from six months to 60 months with a minimum opening deposit of $500.

Capital One also ranked highly in our customer experience category for having a high mobile app rating and a clear, easy-to-use website.
Although Capital One is a major player in online banking, it fell behind some of our top contenders for a few reasons. At 70,000+ ATMs, Capital One’s ATM network is not as large as our top picks, and it doesn’t offer reimbursem*nt for out-of-network ATM fees.
Capital One also scored lower in our fee transparency category. While it does have individual account disclosures for each account type, the disclosures and fee schedules required a bit more digging to find than our top picks.
Capital One’s products:
Credit cards: Capital One offers credit-building cards, cash-back cards, and rewards cards that allow customers to earn points for purchases on dining, travel, and entertainment. It also offers student cards, business cards, and low-intro APR credit cards.

Best quick electronic transfers
First Internet Bank was founded in Indiana in 1999 and was the first state-chartered, FDIC-insured institution to operate entirely online. First Internet Bank’s suite of products includes personal and business banking products, health savings accounts, and even accounts for kids.
First Internet Bank made the ninth spot on our list for its variety of products, low fees, and transparency around fees and product details. First Internet Bank is also the only bank on our list that is part of FedNow — the Federal Reserve’s instant payment service that allows financial institutions to send and receive money within seconds.

Online banking vs. traditional banking: key differences
Online banks and traditional brick-and-mortar banks typically offer the same types of products, but the lack of physical locations for online banks makes the banking experience quite different.
Branches: The most obvious difference between these two banking models is that brick-and-mortar banks have physical branches and online banks do not. If you’re the kind of customer who prefers to speak with a banking associate in person to open an account or resolve issues related to your account, an online bank may not be the right option for you.
Fees and interest: Online banks usually have lower operating costs because they don’t have to maintain office buildings or other physical infrastructure. As a result, an online bank may offer more competitive APYs or lower fees on their products. This isn’t a guarantee, but it’s worth comparing both types of banks to secure the highest interest rates and lowest fees for the products you’re interested in.
ATM access may be limited: Online banks typically do not have their own ATM network and rely on third-party networks to offer their customers ATM access. If you don’t like to carry cash and frequently use electronic transfers or payments, this is probably a non-issue. However, if you do use cash for certain expenses, it may be more difficult to access it without paying an extra fee. Certain third-party networks have the power to charge their own fees, even if your bank doesn’t. Many online banks offer ATM fee reimbursem*nt, but it’s usually capped at a certain amount per month.
Mobile app and online banking experience: Online banks exist solely online, so it’s only natural that most of them will invest heavily in those platforms and provide you with greater digital banking capabilities. This could include mobile check deposits, mobile wallet integration, card locking and unlocking, ATM locator tools, budgeting tools, and more. Many traditional banks offer mobile apps, but they may be more limited in what they offer.

What to consider when choosing an online bank
If you’re considering opening an online bank account, there are a few key factors you should consider to ensure that you choose the best bank for your personal finances.
Is this bank FDIC-insured?
Before considering any bank, whether it’s online or traditional, you should first verify that the bank is FDIC-insured. FDIC insurance protects the money in your deposit account up to $250,000 per depositor, per ownership category. Common ownership categories include single accounts, joint accounts, retirement accounts, trust accounts, business accounts, and more. The easiest way to verify that your bank offers deposit insurance is to use the FDIC’s "BankFind" tool which allows you to type in any bank’s name, URL, or FDIC certification number to verify that it is indeed covered by the FDIC. Many banks also denote their status with “Member FDIC” noted on their homepage.
How easy will it be to access your funds?
The benefit of a bricks-and-mortar institution is that you can usually stop by your local branch to deposit cash and withdraw money free of charge when you need it. Online banks can be a bit tricker. Many online banks offer fee-free ATM networks, but it’s not guaranteed that you’ll have an ATM close to home. ATM cards are also not a guarantee with every online bank, and in some cases your only option for accessing your funds could be via electronic transfer to another bank account.
If you plan to make frequent cash deposits or prefer to pay for certain expenses in cash, you’ll want to consider whether an online bank’s ATM network and ATM card privileges will work for you.
How easy is it to speak to a real person?
Customer service may not be at the top of your list of considerations when choosing a bank, but mishaps can happen, and when they do, you might want to have a real human helping you to resolve it rather than a chatbot.
Be sure to review each bank’s customer service options to learn more about its customer service hours and the different methods for reaching a representative.
What kinds of fees or account minimums does this bank charge?
Online banks don’t typically have the same operational costs as brick-and-mortar banks, which is good news for their customers. The bank might offer fee-free or low-fee accounts in certain instances, or higher APYs. However, this isn’t always the case. Be sure to read the account terms and conditions of any accounts you’re considering and compare those figures with rates and fees from other banks to find the best option for your needs.
What kinds of capabilities does this bank offer on its online and mobile banking platforms?
Research the features available to customers on this bank’s mobile app and online platform. Some banks may not invest heavily in their digital tools and websites, and as a result, you could be limited as a customer. Functions you may find useful include transferring money between accounts, mobile check deposits, setting up automatic bill payments, and more. Think carefully about the features and capabilities that matter most to you and factor those in when making your decision about the best online bank for you.
Frequently asked questions (FAQs)
1. What are online-only banks?
Online banks are banks that offer traditional banking products without operating physical branches. These banks typically offer similar products and financial services to credit unions and traditional banks, but customers do all of their banking online or via mobile app.
2. Are online banks safe?
Online banks are no more or less secure than traditional banks. As long as your bank is FDIC-insured, your deposits are federally insured up to $250,000 per depositor, per ownership category.
3. What is one con to using an online-only bank?
The most obvious drawback of online banking is that you don’t have access to a physical branch or face-to-face customer service when you need it. However, many online banks have expanded their customer support offerings to include late-night, weekend, or even 24/7 service hours to give customers greater access to a service representative.
Best online banks methodology
Our grading system, collected and carefully reviewed by our personal finance experts, comprises over 600 data points for over 20 FDIC-insured online banks to develop our list of the top 10 best online banks. We compared these banks across key metrics, including fees, customer experience, product selection, account features and security, and environmental and social responsibility.
The banks on our list could earn a maximum of 75 points across all five categories. Here’s a closer look at the categories we considered:
Fees: 20 points
We weighed each bank’s fees for its most basic checking and savings account options, as well as overdraft fees and ATM fees. Banks were awarded points for having no or lower fees, greater fee transparency, and clear, easy-to-access fee structures.
Customer service experience: 28 points
Customer service is a key element in a bank’s product offering, especially with online banks, where visiting a branch and asking for in-person help is usually impossible. Banks were scored on metrics including mobile app ratings on Apple and Google storefronts and methods for reaching customer service representatives. Banks that offered phone, chat, and email contacts were awarded the maximum points in that category.
We examined each website for information clarity as part of the customer service offering assessment. This subjective assessment looked at each bank’s website design, ease of navigation, language clarity, and whether customers could easily gather all the needed information to make an informed decision about any particular product.
We also awarded points to banks that offered more extensive ATM networks, credit monitoring tools, and educational resources.
Product selection and account features: 14 points
Each bank we analyzed could earn one point per product for each of the following:
Checking accounts
Savings accounts
High-yield savings accounts
Money market accounts
Certificates of deposit
Mortgages
Personal loans
Auto loans
Home equity lines of credit
We also looked at the speed of ACH transfers and gave banks points for same- or next-day transfers, early access to paychecks, Zelle as a service, and being part of FedNow — the Federal Reserve’s instant payment service.
Security: 10 points
We carefully considered each bank's security measures to protect your money and sensitive information. We looked at factors such as multi-factor authentication, website encryption, alerts for suspicious activity, zero fraud liability, and whether each bank had a dedicated security page or hub.
Environmental and social responsibility: 3 points
Many consumers consider a bank’s carbon footprint and philanthropic efforts before deciding on a particular institution. As such, banks that have dedicated pages to their philanthropic efforts and environmental goals, and have pledged to reach net zero CO2 emissions by 2050 scored up to 3 points for doing so.
