Ally Bank has been a leader in online banking since 2009 and remains the gold standard for full-service digital banking. Their Online Savings Account offers a competitive 4.00% APY with no minimum balance, no monthly fees, and no cap on balances that earn interest. The Interest Checking account earns 0.10–0.25% APY with zero fees and access to 43,000+ Allpoint ATMs.

- Round-up transfers: Automatically round up debit card purchases and transfer the difference to savings
- 24/7 customer support: Phone, chat, and email around the clock — unusual and valuable for an online bank

Best for: Anyone who wants a complete banking relationship (checking, savings, CDs, investing, mortgage) entirely online with excellent customer support. For more savings options, see our guide to the best high-yield savings accounts.
2. Marcus by Goldman Sachs — Best for Pure Savings
Marcus consistently offers one of the highest savings APYs in the market — currently 4.10% with no minimum deposit, no fees, and no maximum balance limits. While Marcus doesn’t offer checking accounts or debit cards, it excels as a dedicated savings destination.
Standout features:
- No-penalty CDs that let you withdraw your full balance after the first 7 days with no early withdrawal penalty
- High-yield CDs with competitive rates across all terms from 6 months to 6 years
- Goldman Sachs backing provides exceptional institutional stability and trust
- Simple, clean interface focused entirely on savings and CDs
Best for: Savers who want the highest possible rate and don’t need checking or debit card access. Pair Marcus savings with a checking account from Ally, SoFi, or your existing bank. Compare with money market accounts and CDs vs. high-yield savings for other savings vehicles.
3. SoFi — Best Checking and Savings Combo
SoFi’s Checking and Savings account (technically one account with two “vaults”) offers 4.00% APY on savings and up to 1.00% APY on checking — both among the best available rates. With direct deposit, you get early paycheck access (up to 2 days early) and access to 55,000+ Allpoint ATMs with no fees.
Standout features:
- Up to $2 million in FDIC coverage through a network of partner banks

Best for: Young professionals who want an all-in-one financial platform with above-average rates on both checking and savings.
4. Discover Bank — Best for Cash Back on Checking
Discover’s Online Savings Account pays 3.90% APY, but the real standout is the Cashback Debit Account: you earn 1% cash back on up to $3,000 in debit card purchases per month. That’s up to $360/year just for using your debit card — with no annual fee and access to 60,000+ ATMs.
Best for: People who prefer debit cards over credit cards and want to earn rewards on everyday spending without the temptation of credit. For credit card rewards, check our cash back credit card guide.
5. Capital One 360 — Best Full-Service with Branch Access
Capital One 360 gives you the best of both worlds: online banking convenience with access to Capital One Café locations (physical branches in select cities) and 70,000+ fee-free ATMs. The 360 Performance Savings pays 3.80% APY, and the 360 Checking account has no fees, no minimums, and early direct deposit.
Best for: People transitioning from traditional banking who want occasional branch access alongside competitive online rates. Compare with our checking account guide for more options.
6. Wealthfront — Best Cash Management Rate
Wealthfront’s Cash Account offers an industry-leading 4.25% APY with FDIC insurance through partner banks covering up to $8 million in deposits. While technically a cash management account rather than a traditional bank account, it functions like a high-yield savings account with features like direct deposit, bill pay, and free transfers.
Best for: Tech-savvy savers looking for the absolute highest rate, especially those already using Wealthfront’s automated investment platform.
7. Synchrony Bank — Best for CD Rates
Synchrony offers some of the highest CD rates across all terms, with no minimum deposit requirements. Their high-yield savings account at 4.00% APY is competitive, but the CDs — from 3 months to 60 months — are the main draw. Synchrony also offers IRA CDs and IRA savings options for tax-advantaged retirement savings.
Best for: CD investors looking for top rates with no minimums. See our guide on CDs vs. high-yield savings accounts for help deciding between CDs and liquid savings.
8. Axos Bank — Best for ATM Fee Rebates
Axos Bank’s Rewards Checking offers unlimited domestic ATM fee reimbursements — use any ATM anywhere in the U.S. and Axos refunds the fee. The account earns up to 1.00% APY with qualifying direct deposits of $1,500/month or more.
Best for: People who frequently need ATM access and don’t want to worry about finding a fee-free network. Particularly useful for travelers or anyone in areas with limited ATM network coverage.
Online Banks vs. Traditional Banks: Full Comparison
| Feature | Online Banks | Traditional Banks |
|---|---|---|
| Savings APY | 3.75%–4.25% | 0.01%–0.50% |
| Monthly fees | Usually $0 | $5–$25 (often waivable with min balance) |
| Minimum balance | Usually $0 | $500–$5,000 to avoid fees |
| ATM access | Network-based (43,000–70,000+) | Own ATMs + shared network |
| Branch access | None (or limited cafés) | Full branch network |
| Mobile app quality | Generally excellent, built mobile-first | Varies widely by institution |
| Customer service | Phone, chat, email (24/7 at some) | In-person + phone + digital |
| Cash deposits | Limited or none (some use retail partners) | ATM and teller deposits |
| FDIC insured | Yes ($250,000+ through partner networks) | Yes ($250,000 standard) |

Key takeaway: Online banks are better for most people who primarily bank digitally. Traditional banks still have an edge if you regularly deposit cash, need in-person assistance for complex transactions, or value having a local banker relationship.
How to Switch to an Online Bank
Step 1: Open Your New Account (Day 1)
Most online bank applications take 5–10 minutes. You’ll need your Social Security number, a valid government-issued ID, and an initial funding source. Most accounts open instantly with no minimum deposit required.
Step 2: Set Up Direct Deposit (Days 2–5)
Update your direct deposit with your employer using your new routing and account numbers. This unlocks the highest APYs, early paycheck features, and other direct-deposit-only perks at many online banks.
Step 3: Move Automatic Payments (Days 5–14)
Update billing information for all recurring payments: utilities, subscriptions, loan payments, insurance premiums. Keep a running list and check them off one by one as confirmed. Set a reminder to verify each one processes correctly on the next billing cycle.
Step 4: Transfer Your Balance (Days 14–30)
Once your direct deposit is flowing and automatic payments are set up, transfer the bulk of your balance from your old bank. Keep your old account open with a small balance ($100–$200) for 2–3 months to catch any straggling automatic payments you may have missed.
Step 5: Close Your Old Account (Day 60–90)
After confirming everything runs smoothly through your new bank for at least two full billing cycles, close your old account. Request closure in writing and get confirmation. Transfer any remaining balance first.
Pro Tip: Don’t close your old account too quickly. Keeping it open with a minimal balance for 2–3 months gives you a safety net while you verify all automatic payments have been successfully transferred.
What About Cash Deposits?
The biggest limitation of online banks is depositing cash. Here are your options:
- Retail deposit networks: Some online banks (like Ally via Green Dot) let you deposit cash at participating retailers (Walgreens, CVS, Dollar General) for a small fee ($3–5)
- Money orders: Buy a money order with cash and deposit it via mobile check deposit
- Keep a traditional account for cash: Maintain a free checking account at a local bank or credit union specifically for cash deposits, then transfer to your online bank
- ATM deposits: Some online banks that use partner bank ATMs allow cash deposits at those ATMs (Capital One, for example)
Are Online Banks Safe?
Yes. For more details, see our guide on best credit unions. Online banks are just as safe as traditional banks when they’re FDIC-insured (all banks on our list are). Your deposits are protected up to $250,000 per depositor, per institution — and some online banks offer even more coverage through partner bank networks. SoFi, for example, provides up to $2 million in FDIC coverage, and Wealthfront covers up to $8 million.
From a cybersecurity standpoint, online banks often invest more heavily in digital security since their entire business depends on it. Look for banks that offer two-factor authentication, biometric login, real-time fraud alerts, and automatic session timeouts.
Frequently Asked Questions
What’s the difference between an online bank and a neobank?
Online banks are typically FDIC-insured institutions that happen to operate exclusively online (like Ally or Discover). Neobanks are fintech companies that partner with FDIC-insured banks to offer banking services through their own apps (like Chime or Current). The key difference is whether the company itself holds a banking charter. Both can be safe, but always verify FDIC coverage.
Can I get a mortgage or loan from an online bank?
Yes. Many online banks offer mortgages, personal loans, auto loans, and more. Ally, SoFi, and Capital One all offer lending products. In some cases, being an existing customer gets you a rate discount. For loan comparisons, see our guides on personal loans and home equity options.
What happens if an online bank fails?
The same thing that happens if a traditional bank fails: the FDIC steps in and insures your deposits up to $250,000. In practice, the FDIC typically arranges for another bank to acquire the failed bank’s deposits, and you’d continue banking as usual with the new institution.
Do I need to switch banks entirely, or can I use both?
You absolutely can — and many people do. A common strategy is keeping a traditional bank for cash deposits and a local relationship while using an online bank for savings (to earn higher rates) and everyday spending. There’s no rule that says you must choose one or the other.
How do online banks offer higher rates?
Without the expense of maintaining physical branches (real estate, utilities, teller salaries), online banks have significantly lower operating costs. They pass these savings to customers in the form of higher deposit rates and fewer fees. The math is simple: a traditional bank might spend $200–$400 per year per customer on branch overhead, while an online bank spends near zero.
Bottom Line
Online banks offer objectively better rates and lower fees than traditional banks for most banking needs. The trade-off — no physical branches — is increasingly irrelevant as mobile banking, mobile check deposit, and electronic payments dominate how most people interact with their money.
For most people, the best approach is to open a high-yield savings account at an online bank immediately (even if you keep your current checking account) and start earning 10–15x more on your savings. Over time, you can migrate more of your banking online as you become comfortable with the experience. Every dollar sitting in a 0.01% savings account at a traditional bank is money left on the table.
