Online banks consistently offer better interest rates and lower fees than traditional brick-and-mortar banks. With no physical branch overhead, they pass those savings to customers in the form of higher yields on savings accounts and fewer monthly maintenance fees.
What to Look for in an Online Bank
Before choosing an online bank, consider these factors:
- APY on savings accounts: Look for rates significantly above the national average.
- Monthly fees: Top online banks charge zero monthly maintenance fees.
- FDIC insurance: Confirm the bank is FDIC-insured for up to $250,000 per depositor.
- ATM access: Check whether the bank reimburses ATM fees or has a large fee-free network.
- Mobile app quality: Mobile check deposit, Zelle access, and customer support responsiveness matter.
- Minimum balance requirements: Many online banks have no minimums at all.

Online Banks vs. Traditional Banks: How Much More Can You Earn?
The national average savings account APY at traditional banks is typically around 0.45%. Many top online banks offer APYs of 4.5% to 5.0% or higher on high-yield savings accounts. On a $10,000 balance, the difference is roughly $450 per year in additional interest.
Are Online Banks Safe?
Yes. As long as the bank is FDIC-insured, your deposits are protected up to $250,000 per depositor, per ownership category. FDIC insurance works the same whether the bank is online or physical. You can verify FDIC status at fdic.gov.
Potential Drawbacks of Online Banks
- No physical branch if you need in-person assistance
- Cash deposits can be difficult or impossible
- Transfers between external accounts typically take 1–3 business days
- Some have limited product offerings (no mortgages, auto loans, etc.)
Bottom Line
If you are keeping money in a traditional bank savings account earning near zero, switching to an online bank is one of the easiest ways to earn meaningfully more on your cash. All of the banks listed above are FDIC-insured, charge no monthly fees, and require no minimum balance. The only cost is the 15 minutes it takes to open an account.
