How we picked the best online banks 2026
We evaluated online banks on six weighted criteria: combined APY across checking and savings (25%), monthly fees and minimum balance requirements (20%), ATM network access and reimbursement policies (15%), mobile app quality and feature completeness (15%), customer service responsiveness (15%), and FDIC insurance backing (10%). The winners offered measurably better terms than traditional banks across at least four of these categories, with no significant compromises on the others. Each bank was tested with a real funded account over 30 days.

Bank-by-bank breakdown
Each pick fits a different banking need. Here's the right one for each priority.
1. SoFi — best for primary banking
SoFi combines a 4.20% APY on savings with 0.50% on checking — both top-tier rates — and adds early direct deposit, no overdraft fees, and access to a 55,000-ATM network with reimbursement on out-of-network withdrawals. The investing and lending features in the same app are useful if you want financial consolidation. SoFi has been the fastest-growing online bank since 2023, and the customer experience has kept up with that growth.
2. Ally Bank — best balanced experience
Ally's 4.10% savings APY and 0.25% checking APY don't lead the market, but the bank's 24/7 customer service, bucket-based savings goal features, and consistent rate philosophy make it the most trustworthy primary banking choice. Ally raises rates promptly when the Fed does and rarely runs misleading promotional teasers. The mobile app routinely ranks in the top three of any banking app survey.
3. Discover Bank — best for high-yield checking
Discover pays 1.00% APY on checking — the highest checking rate among major online banks — plus 1% cashback on debit card purchases up to $3,000 a month. The savings APY of 3.90% is competitive though not category-leading. For consumers who keep substantial balances in checking, Discover's combination is hard to beat.
What to look for in an online bank
Beyond headline APYs, focus on the operational details that affect your daily banking experience. ATM network access matters if you regularly need cash — banks like SoFi and Ally reimburse out-of-network ATM fees, while others restrict you to a smaller network. Mobile check deposit limits range from $5,000 to $50,000 depending on the bank, which matters if you receive larger checks. Customer service hours and channels vary widely; banks with 24/7 phone support are more useful when fraud or transfer issues arise unexpectedly.
Online bank red flags to avoid
- Teaser APYs that drop sharply after the first 90 days.
- Required minimum balances above $1,000 to avoid monthly fees.
- External transfer times longer than three business days.
- Customer service available only by email or chat with no phone option.
- Banks operating without direct FDIC insurance (relying on fintech sponsor banks adds risk).
- Hidden fees for paper statements, account closure, or excessive withdrawals.
Frequently asked questions
Are online banks safe?
Yes, as long as the bank carries FDIC insurance directly or through a sponsor bank. Funds up to $250,000 per depositor per institution are federally insured against bank failure. Always verify FDIC insurance on the bank's website before depositing significant funds. Fintech apps that aren't banks themselves rely on sponsor banks — check which sponsor bank holds your money.
Can I deposit cash at an online bank?
Most online banks don't accept direct cash deposits. Workarounds include depositing cash at a Green Dot retail location (Walgreens, CVS), mailing a money order to the bank, or maintaining a small account at a traditional bank for cash deposits. SoFi and Chime offer Green Dot deposits, while Ally and Discover require workarounds. This is the single biggest practical limitation of online banking.
How do online banks make money with no fees?
Online banks earn the same way traditional banks do — by lending out customer deposits at higher rates than they pay in interest. Without branch overhead, they can pass more of that spread back to customers in the form of higher APYs while still being profitable. Some online banks also earn interchange fees from debit card transactions, which is why some pay rewards on debit purchases.
Should I close my traditional bank account?
Probably not entirely. Most experienced online banking users keep a small traditional bank account ($500-$1,000) for cash deposits, notarized documents, and the occasional need for in-person services. The bulk of your money belongs in higher-yielding online accounts, but a minimal traditional banking relationship adds operational flexibility.
