Online banks have transformed personal banking by eliminating the overhead costs of physical branches — and passing those savings to customers in the form of higher interest rates and zero-fee accounts. In 2026, the best online banks offer savings account APYs well above the national average, no monthly maintenance fees, and comparable protections to traditional banks (all FDIC-insured).
Here’s how the top picks compare across key categories.

SoFi also offers a $300 sign-up bonus for qualifying new accounts with direct deposit, and no account fees of any kind.

Marcus by Goldman Sachs: Best for Savings Only
Marcus offers one of the most consistently competitive high-yield savings APYs with no strings attached — no direct deposit requirement, no minimum balance. There’s no checking account, which means you’ll need a separate bank for daily spending.
- Savings APY: 4.40%
- No fees, no minimums, no direct deposit required
- Best for: Parking emergency funds or savings you don’t need to access daily
Discover Bank: Best Cashback Checking Account
Discover’s Online Checking account earns 1% cash back on up to $3,000 in debit card purchases per month. Paired with a competitive savings APY, it’s one of the best full-banking options for everyday spenders.
- Cashback checking: 1% on up to $3,000/month in debit purchases
- No fees, large ATM network (60,000+ fee-free ATMs)
- Best for: Daily spenders who want to earn on debit purchases
Capital One 360: Best Branch-Accessible Online Bank
Capital One 360 bridges online and in-person banking with Capital One Cafes (in major cities) and a full-featured mobile app. Savings APY is slightly below competitors but still far above traditional banks. The 360 Checking account earns interest, has no fees, and supports Zelle.
American Express High Yield Savings: Best for Simple Savings
AmEx offers a no-frills, extremely safe savings account with 4.35% APY. No checking, no investment accounts — just savings. If you already trust the AmEx brand and want a place to park cash, this is straightforward and reliable.
How to Choose the Right Online Bank
You need a full banking setup (checking + savings)
Choose Ally, SoFi, Capital One 360, or Discover. All offer both accounts with no fees and competitive rates.
You just want the highest savings rate
Marcus by Goldman Sachs and SoFi are top choices. SoFi requires direct deposit for its highest rate; Marcus does not.
You want cash back on debit spending
Discover’s 1% cashback checking is the standout option.
You want one app for banking, investing, and loans
SoFi is the most complete platform in this category.
Are Online Banks Safe?
Yes. All of the banks listed here are FDIC-insured, which means deposits up to $250,000 per depositor are protected by the federal government — the same protection as any traditional bank. There is no meaningful safety difference between an online bank and a traditional branch bank when both carry FDIC insurance.
What Online Banks Don’t Offer
- Cash deposits (most require workarounds like Green Dot or Walmart)
- In-person notary or safe deposit boxes
- Face-to-face relationship banking
For most people, these limitations are minor. If you need regular cash deposits, consider a hybrid approach: keep a local credit union for cash and an online bank for savings and day-to-day spending.
Bottom Line
Ally is the best all-around choice for most people — reliable, full-featured, and consistently competitive on rates. Marcus or AmEx High Yield Savings are ideal if you just need a place for savings with no strings attached. SoFi is worth considering if you want a full financial platform in one app. Any of these is a significant upgrade over keeping money in a traditional bank earning 0.01%.
