The Alto Online Savings Account doesn’t have a monthly fee, a minimum opening deposit or a minimum balance requirement. On top of that, the high-yield savings account pays a solid 3.15% annual percentage yield — many times higher than the national average rate of 0.38%.

There’s no limit to the number of transfers and withdrawals you make, which not all banks offer. Without access to ATMs or bank branches, the Alto savings account requires an external bank account to transfer your money to — but that could be a plus if you’re trying to build up your savings.

Alto offers a simple choice of standard-term certificates of deposit. CDs are available in terms ranging from six months to five years. Rates are solid, and there are no fees and no minimum opening deposit requirements, though you must fund your account within 10 days of opening.

CDs are automatically renewed, so it’s important to withdraw your funds when your CD matures. You’ll have a grace period of 10 days to take action before the bank puts the money in a CD with the same term length as the one that matured.

Customer experience & overdraft fees

Customer experience

As an online-only bank, Alto doesn’t have any branches. There’s also no mobile app. The bank offers account alerts by email and FAQs on the website.

The bank also doesn’t offer a checking account or ATM access. The only option for depositing funds is to transfer from another bank, so you must have an external bank account to both fund your account and withdraw from the account. Alto doesn’t limit the number of transfers and withdrawals, which isn’t something all banks allow.

Rating methodology

How we rate banks and credit unions

Banking writers and editors use an objective methodology to rate banks, credit unions, and other providers, and to recommend the best products.

100+

Financial institutions reviewed

We took a close look at around 100 financial institutions and financial service providers, including the largest U.S. banks based on assets, internet search traffic and other factors; the nation’s largest credit unions, based on assets and membership; and other notable players in the industry. We rated them on criteria including annual percentage yields, minimum balances, fees, digital experience and more.

30+

Categories assessed

Each provider is evaluated across five weighted categories and 30 subcategories, including checking and savings accounts, certificates of deposit, customer experience, and overdraft services. For banks or credit unions without one or more types of accounts, the overall rating is modified to include only applicable categories. Institutions are not penalized if they don't offer every type of account.

60+

Data points analyzed

We considered more than 60 data points for each provider. Depending on the category, these included account fees and rates (such as annual percentage yields), ATM and branch access, account features, account bonuses, customer service access and user-facing technology, such as innovative tools and mobile apps. We gathered this information for each financial institution from its website, a media representative or both.

Star rating categories

The review team is made up of seasoned writers and editors who cover personal banking deposit accounts, such as checking, savings and certificates of deposit, as well as related banking services, such as overdraft programs and ATM networks. For providers without one or more types of accounts, the overall rating is modified to include only applicable categories. Institutions are not penalized if they don't offer every type of account.
