American Express National Bank and Marcus by Goldman Sachs are popular online banks, each with a competitive High Yield Savings Account (HYSA) option. But in an environment where interest rates are falling every day, choosing the right bank and savings account is crucial.
We’ve looked at the HYSAs offered by American Express and Marcus by Goldman Sachs to help you determine which is best for your savings needs.

The Goldman Sachs Marcus Online Savings Account offers 3.90% APY as of this writing. That’s more than nine times the national average rate on savings accounts.
There are no monthly maintenance fees and the account does not require a minimum opening deposit or minimum balance to earn this rate. Interest is accrued daily and credited to your account monthly.
One of the downsides of the Marcus by Goldman Sachs HYSA is that it doesn’t offer an ATM card. Therefore, if you need to access your funds, you will need to initiate a transfer to another account. The good news: It allows same-day transfers of $100,000 or less to it from other banks. There is also no limit on the number of withdrawals or transfers you can make from your account.

The American Express High Yield Savings Account offers a slightly lower 3.80% APY with no monthly fees. There are also no minimum opening deposits or minimum balance requirements to earn interest or keep your account open.
Interest on this savings account is compounded daily and credited to your account monthly. Like Marcus, this account also does not include any ATM cards, debit cards, or checks. Also, transfers from your savings account to an external bank account can take up to three business days to complete.

These two accounts are quite similar.
Goldman Sachs’ Marcus offers a slightly higher rate than American Express (3.90% APY vs. 3.80% APY). However, for the average person, a difference of 0.10% will have little impact on the return on their savings account.
For example, let’s say you open a savings account and deposit $1,000, then let that money sit for a year without making any additional deposits. At 3.90% APY, you’ll earn $39.77 in interest over a year.
Now let’s say your account earns 3.80% APY. In this case, a $1,000 deposit balance over one year would earn $38.73 in interest. As you can see, the difference is quite negligible.
Of course, the more money you have in your savings account, the more impact the interest rate will have on future compounding returns.
That said, it’s important to understand that savings account interest rates are variable, meaning the bank can change the rate at any time at its discretion. An account that offers the highest rate today may not have the highest rate tomorrow, so it shouldn’t be the only factor you consider when choosing a high-yield savings account.
