At NerdWallet, we adhere to strict standards of editorial integrity to help you make decisions with confidence. Some of the products we feature are from our partners. Here’s how we make money.

Online banks Ally and Synchrony can earn you more interest than traditional banks can, partly because they don’t have to shell out millions of dollars to maintain branches.

But the two banks have differences that can matter: Synchrony has no checking accounts or mobile banking apps, yet its savings rates are competitive enough to consider if you’re focused on accounts with high annual percentage yields.

    Ally offers checking, and Synchrony doesn’t. If you’re shopping for a new checking account, Ally has a lot to offer. The account even reimburses some ATM fees and earns interest, which are rare features for checking accounts.

    Both banks’ savings accounts are nearly identical, except for their interest rates, which continue to climb in the current rising-rate environment. You can’t go wrong with either. Their rates are more than 20 times better than the national average savings rate of 0.07%.

    Synchrony’s CD rates are generally higher than Ally’s for one-year terms and longer, but Synchrony requires a $2,000 minimum deposit, which is steep. Ally has no minimum deposit, but its rates vary at minimum balances of $0, $5,000 and $25,000, with the higher rates reserved for larger balances.

    Customer serviceAvailable by phone, chat, email and social mediaAvailable by phone, email and social media, but no online chat
    Ally has a mobile app, Synchrony doesn’t. Ally’s mobile app lets you transfer money, check balances and deposit checks. To do the same things on your phone with Synchrony, you need to open its website on a web browser. As far as customer service, you can reach either bank by phone, email or Twitter, but Ally also has chat and provides estimated wait times for phone lines. Synchrony offers help at its one branch location in Bridgewater, New Jersey, but it won’t do you much good if you’re not nearby.

    Overdraft fees

    Overdraft protection transfer fee$0N/A
    Extended overdraft fee$0N/A
    Synchrony doesn’t have overdraft fees, but Ally does. Since Synchrony doesn’t offer a checking account, it doesn’t allow an overdraft to occur. Ally charges $25 for overdrafts, which is significantly less than the $34 median fee among big banks, and only once per day. Some banks don’t have a daily maximum for overdraft fees.

    Ally is hard to beat

    Synchrony’s CD rates are slightly higher than Ally’s, but its overall game doesn’t quite compete. If you’re looking to keep your checking and savings accounts under the same roof while having access to a mobile app, you’ll be disappointed by Synchrony. Ally’s accounts and mobile tools, meanwhile, are among the best we’ve come across for any bank.
