American Express savings accounts pay more interest than most banks, but only if you meet their terms and keep a large balance
American Express Bank offers a high-yield savings account through its online banking platform. The account pays interest rates that are typically higher than traditional brick-and-mortar banks, though the exact rate changes with the market. There is no monthly fee, no minimum balance requirement to open the account, and no penalty for withdrawals. The tradeoff is that you cannot walk into a branch—all deposits and withdrawals happen online or by mail.
Whether it is worth opening depends on three things: how much money you plan to keep in savings, how often you need to move money in and out, and whether you already have accounts elsewhere that might be simpler to manage together.
Key Takeaways
- American Express savings accounts have no monthly fees or minimum balance, so there is no cost to opening one even if you only deposit a small amount.
- The interest rate is higher than most traditional banks, but you earn that rate only on money sitting in the account—not on money you are spending or moving frequently.
- All transactions happen online or by mail; there are no physical branches, which makes deposits slower if you need to move cash quickly.
- The account is FDIC-insured up to $250,000, so your money is protected the same way it would be at any other bank.
How the interest rate works and what you actually earn
American Express publishes its savings account rate on its website, and that rate applies to all balances in the account. The rate is not tiered—you do not earn a higher percentage on your first $10,000 and a lower percentage on money above that. Instead, every dollar earns the same rate.
The rate itself changes over time based on Federal Reserve decisions. When the Fed raises rates, American Express typically raises its rate within days or weeks. When the Fed cuts rates, the bank's rate falls as well. This means the amount you earn each month is not fixed—it goes up and down with the broader economy.
To know whether the rate is competitive right now, compare it to other online banks' rates. Banks like Marcus, Ally, and Capital One 360 publish their rates publicly. If American Express is offering 4.50% and Marcus is offering 4.35%, the difference on a $10,000 balance is about $15 per year. On $100,000, it is about $150 per year. The gap matters more the larger your balance is.
Why you might open one: low fees and no strings attached
American Express charges no monthly maintenance fee. You do not have to maintain a minimum balance to keep the account open or to earn the full interest rate. You can withdraw money whenever you want without penalty. This means there is almost no downside to opening the account if you already have money in savings elsewhere.
The account also comes with FDIC insurance, which means if American Express Bank fails, the federal government protects your money up to $250,000. This is the same protection you get at any other bank, so it is not a reason to choose American Express over another bank—it is just a baseline safety feature.
If you have an American Express credit card, you may find it slightly more convenient to have a savings account with the same company. You can see both accounts in one login. But convenience alone is not a strong reason to move money to a lower-paying account, so compare rates first.
Why you might not: slower deposits and limited access
American Express Bank is online-only. You cannot deposit cash at a branch or an ATM. If you have cash, you have to mail it in, which takes several days. If you need to move money quickly—say, to cover an unexpected expense—you can transfer it to another bank account you own, but that transfer also takes one to three business days depending on your other bank.
This matters most if you are the kind of person who gets paid in cash, receives checks regularly, or needs to access your savings quickly. If your paycheck goes directly to your checking account and you only move money to savings once a month, the delay is not a problem.
You also cannot use an American Express savings account as your main checking account. There is no debit card, no check-writing, and no bill pay. It is a savings account only, which means you need another bank for everyday spending. If you are trying to consolidate all your banking in one place, this account does not do that.
Comparing American Express to other online savings accounts
| Bank | Current Rate | Minimum Balance | Monthly Fee | FDIC Insured |
|---|---|---|---|---|
| American Express Bank | Varies; check website | None | None | Yes, up to $250,000 |
| Marcus by Goldman Sachs | Varies; check website | None | None | Yes, up to $250,000 |
| Ally Bank | Varies; check website | None | None | Yes, up to $250,000 |
| Capital One 360 | Varies; check website | None | None | Yes, up to $250,000 |
All of these banks offer similar features: no fees, no minimum balance, FDIC insurance, and online-only access. The main difference is the interest rate, which changes frequently. On any given day, one bank might pay 4.50% and another might pay 4.35%. Over a year, that 0.15% difference adds up, but it is not enormous unless you have a very large balance.
The second difference is how fast they process transfers. Some banks move money between accounts in one business day; others take two or three. If speed matters to you, check the specific bank's transfer policy before opening an account.
When a savings account makes sense versus other places to keep money
A savings account is the right place for money you want to keep safe and earn some interest on, but might need within the next few years. If you are saving for a down payment, a car, or an emergency fund, a savings account works well.
If you have money you will not need for five or ten years, a certificate of deposit (CD) might pay more interest. CDs lock your money away for a set period—three months, one year, five years—and pay a higher rate in exchange. If you withdraw early, you pay a penalty. American Express offers CDs as well, so you can compare the rates on their website.
If you have a very large balance—$250,000 or more—you might want to split it across multiple banks so that all of it stays FDIC-insured. Each bank insures up to $250,000 per person, so spreading money across two banks protects twice as much.
How to decide if it is worth opening
Start by checking the current interest rate on American Express's website and comparing it to at least two other online banks. If American Express is paying 0.25% or more above the others, it is worth opening. If it is paying the same or less, there is no reason to choose it over a bank you might already use.
Next, think about how you move money. If you get paid by direct deposit and only move money to savings once a month, American Express works fine. If you deposit cash regularly or need quick access to your savings, an online-only bank is less convenient.
Finally, consider whether you want all your accounts in one place. If you already have an American Express credit card and prefer to see everything together, that is a small reason to open the account. But it should not override a better interest rate elsewhere.
Frequently Asked Questions
Can I transfer money from my American Express credit card to the savings account?
No. The credit card and the savings account are separate products. You can pay your credit card bill from the savings account, but you cannot move a credit card balance into savings. To fund the savings account, you transfer money from another bank account you own.
What happens if American Express Bank fails?
Your money is protected by FDIC insurance up to $250,000. The federal government would transfer your balance to another bank or send you a check. This has not happened to American Express Bank, and it is a very rare event at any large bank.
Can I set up automatic transfers to the savings account?
Yes. You can schedule recurring transfers from another bank account to American Express on a weekly, biweekly, or monthly basis. This is useful if you want to move money to savings automatically without thinking about it each time.
Is the interest rate may provide to stay the same?
No. The rate changes whenever the Federal Reserve changes its benchmark rate, and American Express can also change its rate independently. You will earn whatever the current rate is on the day the interest is calculated, which is usually monthly.
Do I need an American Express credit card to open a savings account?
No. You can open a savings account with American Express Bank without having a credit card. The two products are separate, though having both with the same company means you see them in one login.
