You can open more than one American Express savings account, but American Express Bank limits how many you can hold at the same time

American Express Bank allows you to open multiple savings accounts, but the limit is typically two accounts per person. This means you could have two separate savings accounts earning interest at the same time, each with its own balance and account number. The second account functions exactly like the first — it earns the same interest rate, follows the same rules, and appears as a separate line item when you log in.

The reason to open a second account is usually practical: you might want to separate money by purpose (one for an emergency fund, one for a specific goal), or you might want to move money between accounts without involving external transfers. Since both accounts are at the same institution, moving money between them is when ready and costs nothing.

If you already have two American Express savings accounts and want to open a third, you would need to close one of the existing accounts first. American Express does not make exceptions to this limit based on account balance or how long you have been a customer.

Key Takeaways

  • American Express Bank allows you to hold up to two savings accounts at the same time under your name.
  • Both accounts earn the same interest rate and have the same terms, so the second account is not a different product — it is a duplicate of the first.
  • Transfers between your two American Express savings accounts happen when ready and do not count against any transfer limits.
  • If you want to open a third account, you must close one of your existing accounts first.

How to open a second account

Opening a second American Express savings account follows the same process as opening your first one. You log into your American Express Bank account online, navigate to the account opening section, and provide the same information you gave when you opened the first account — your Social Security number, address, and date of birth. American Express will verify this information against what they already have on file.

The process takes about five minutes. Once you submit it, American Express typically approves or denies the request within one business day. If approved, the new account appears in your online dashboard when ready, and you can begin depositing money to it right away. You will receive a separate account number for the second account, which you can use if you want to set up direct deposits to that specific account.

There is no fee to open a second account, and you do not need to maintain a minimum balance in either account. If you close the second account later, you can withdraw the balance in full or transfer it to your first account.

What happens to interest if you split your money across two accounts

Interest accrues on each account separately based on that account's balance. If you have $10,000 in your first account and $5,000 in your second account, each balance earns interest at the same rate, but the interest is calculated and paid on each balance independently. You will see two interest deposits each month — one for each account.

From a total interest perspective, splitting your money across two accounts does not change how much interest you earn. The combined interest on $10,000 plus $5,000 is the same whether the money sits in one account or two. The only difference is that you see the interest posted to two separate accounts instead of one.

Interest is typically posted monthly, though the exact date varies. You can check your account online to see when interest was last posted and what the current balance is in each account.

Why you might want a second account

The most common reason to open a second account is to organize money by purpose without moving it to a different bank. You could keep your emergency fund in one account and money set aside for a vacation or home repair in the other. This separation makes it easier to see how much you have allocated to each goal without doing math or keeping a spreadsheet.

A second account can also be useful if you receive income from multiple sources and want to deposit each source into a separate account. For example, if you have a primary job and freelance work, you could set up direct deposit from your employer to one account and transfer freelance payments to the other. This does not affect how much you earn in interest, but it can make tracking income easier.

Some people use a second account as a buffer. They keep their main savings in one account and use the second account as a holding area for money they are about to spend, so they do not accidentally dip into their primary savings.

Closing a second account if you no longer need it

Closing an American Express savings account is straightforward. You can do it online through your account dashboard or by calling American Express Bank customer service. Before you close the account, you need to withdraw or transfer any remaining balance — American Express will not close an account that still has money in it.

Once the account is empty, the closure typically takes one to two business days to process. After that, the account no longer appears in your online dashboard, and you cannot deposit money to it. If you change your mind within a short window, you may be able to reopen the account, but American Express does not may provide this, so it is worth confirming before you close.

There is no fee to close an account, and closing one account does not affect your other account or your relationship with American Express Bank.

Joint accounts and accounts for other people

The two-account limit applies to accounts held in your name alone. If you have a joint account with another person, that account counts as one of your two. You cannot open a joint account and then open two additional individual accounts — the limit is two total accounts across all ownership structures.

Each person has their own two-account limit. If you and your spouse both have individual accounts at American Express Bank, your spouse can also open up to two accounts in their name. The accounts are completely separate — your spouse's accounts do not count toward your limit, and you cannot access their accounts without being added as an authorized user.

Frequently Asked Questions

Can I have one account in my name and one joint account with someone else?

Yes. You can have one individual account and one joint account, and that uses up your two-account limit. If you want to open a third account, you would need to close either the individual or the joint account first.

Do I need separate login credentials for each account?

No. Both accounts appear in the same login dashboard. You use the same username and password to access both accounts, and you can switch between them without logging out.

Can I set up automatic transfers between my two accounts?

American Express Bank does not currently offer automatic recurring transfers between your own accounts. You can transfer money manually whenever you want — the transfer is when ready — but you cannot schedule it to happen on a set date each month.

What if I want to open a second account but I am worried about the interest rate changing?

Both accounts are always subject to the same interest rate. If American Express changes the rate on their savings accounts, the change applies to both of your accounts at the same time. Opening a second account does not lock in a rate or protect you from future rate changes.

Can I have a second account at American Express Bank and also use their other products?

Yes. The two-account limit applies only to savings accounts. You can have two savings accounts and also hold a money market account, a certificate of deposit, or other American Express Bank products at the same time. The limit is specific to savings accounts.
