Why Switch to an Online Bank?
Online banks operate without expensive branch networks, which means they pass those savings on to customers through higher savings rates, lower fees, and better account features. In 2026, the gap between traditional banks and online banks has never been wider.
The average traditional bank savings account earns 0.45% APY. The best online bank savings accounts earn 4.50% or more. That is not a small difference — it is the difference between earning $45 and $450 on a $10,000 balance each year.

No monthly fees, no overdraft fees up to $200 on qualifying accounts, and early access to direct deposit up to two days early. Savings rates are lower than competitors, but Chime excels on fee-free everyday banking.

What to Look for in an Online Bank
FDIC Insurance
Every bank on this list is FDIC insured to at least $250,000 per depositor. Never keep money at a financial institution that is not FDIC insured.
APY on Savings
The savings rate matters more than most people realize. A 1% difference on $50,000 is $500 per year. Over 10 years, the difference compounds significantly.
ATM Access
Many online banks partner with ATM networks to give customers fee-free access nationwide. Ally’s Allpoint network has 55,000+ ATMs. Discover has 60,000+. Always check ATM availability before switching.
Mobile App Quality
Your phone is your branch. Check app store reviews before committing to an online bank. The best apps offer mobile check deposit, instant transfers, easy account management, and real-time notifications.
Customer Service
The best online banks offer 24/7 customer service by phone and chat. Ally and Discover consistently rank highest for customer service among online banks.
Online Banks vs. Traditional Banks
The main advantage of traditional banks is physical branches — useful for depositing cash or handling complex transactions in person. If you regularly deal with cash, a hybrid approach works well: use a traditional bank for cash deposits and an online bank for savings.
For everything else — savings rates, fees, digital experience, and customer service — online banks win consistently.
Bottom Line
In 2026, there is almost no reason to keep your savings at a traditional big bank. Online banks offer higher rates, lower fees, and better technology. Ally is the safest all-around choice. Marcus wins on savings rates alone. SoFi is best if you want to consolidate all your financial products in one place.
Making the switch takes about 15 minutes. The earnings difference can amount to hundreds or thousands of dollars per year.
