Ally Bank vs Discover Bank: Which Online Bank Is Best?

Ally Bank and Discover Bank are two pioneers of online banking that have built loyal customer bases by offering higher interest rates, lower fees, and better digital experiences than traditional banks. Both have been operating as online banks for over a decade and have matured into full-featured banking platforms. This comparison examines which one deserves your deposits.

Ally Bank's Online Savings Account has been a benchmark for high-yield savings, consistently offering rates at or near the top of the market. Ally offers a competitive APY with no minimum balance, no monthly fees, and no minimum opening deposit. Ally's savings account includes a unique "buckets" feature that lets you organize savings within a single account by creating virtual sub-accounts for different goals (emergency fund, vacation, down payment, etc.). Each bucket tracks its balance independently while all money earns the same APY. This organizational tool is genuinely useful and something most competitors do not offer.

Discover Bank's Online Savings Account also offers a competitive high-yield APY with no monthly fees and no minimum balance requirement. Discover requires a small minimum opening deposit (currently 0 dollars, though this has varied historically). The savings account is straightforward without the organizational features that Ally provides. Both banks adjust their savings rates in response to Federal Reserve actions, and their rates tend to track closely, with one occasionally offering a slightly higher rate than the other.

Checking accounts are where the two banks diverge more significantly. Ally's Interest Checking account pays a tiered APY (higher rate on balances above 15,000 dollars) with no monthly fees, no minimum balance, and free access to over 43,000 AllPoint ATMs. Ally reimburses up to 10 dollars per statement cycle in out-of-network ATM fees. Discover's Cashback Debit account is unique — it earns 1 percent cash back on up to 3,000 dollars in debit card purchases per month. This is the only checking account from a major bank that offers cash back on debit card spending. Discover also provides free access to over 60,000 ATMs through the AllPoint and MoneyPass networks with no out-of-network ATM fees charged by Discover (though the ATM owner may still charge a fee).

CD offerings from both banks are robust. Ally offers CDs with terms from 3 months to 5 years, plus two unique products: the Raise Your Rate CD (allows you to increase your rate once or twice during the term if rates go up) and the No Penalty CD (11-month term with no early withdrawal penalty). Discover offers CDs from 3 months to 10 years, generally with competitive rates. Discover's longer-term CD options (7-year and 10-year) are unusual in the industry and can be attractive for long-term savings goals in a declining rate environment.

For investing, Ally has a clear advantage. Ally Invest offers self-directed trading with commission-free stocks and ETFs, options trading, and managed portfolios (robo-advisor service). Ally also offers a Cash-Enhanced Managed Portfolio that keeps 30 percent of your portfolio in cash earning a competitive rate, which appeals to conservative investors. Discover does not offer investing services, so customers who want banking and investing under one roof should choose Ally.

Money market accounts are offered by both banks. Ally's Money Market Account offers tiered interest rates with check-writing ability, a debit card, and no monthly fees. Discover's Money Market Account similarly offers tiered rates with check writing and a debit card. Rates are generally comparable between the two.

Customer service is an area where both banks excel and differentiate themselves from larger banks. Ally offers 24/7 phone support, live chat, and email support, consistently earning high marks in customer satisfaction surveys. Ally also provides a robust help center and active social media support. Discover offers U.S.-based customer service available 24/7 by phone, consistently ranking at or near the top in J.D. Power customer satisfaction rankings for direct banks. Discover's customer service reputation is arguably the strongest in online banking.

Mobile app quality is excellent for both banks. Ally's app offers comprehensive account management, Zelle integration, mobile check deposit, spending insights, and access to Ally Invest. Discover's app provides account management, Zelle, mobile check deposit, and credit score monitoring. Both apps receive 4.7-plus ratings in app stores.

One notable difference is that Discover operates a small number of physical locations (primarily in the Delaware area) and Discover cardholders can make fee-free deposits at a network of retailers. Ally is entirely online with no physical presence, which means you cannot deposit cash directly into an Ally account without using a workaround like depositing into another bank and transferring.

The overall verdict is that Ally Bank is the better choice for customers who want a comprehensive online banking platform with investing, excellent savings tools like buckets, and a money market account. Discover Bank is the better choice for customers who prioritize cash back on debit card purchases, value top-tier customer service, want occasional access to physical locations, and do not need investing services integrated with their bank.
