What you get with an American Express high yield savings account

American Express Bank offers a savings account that pays interest on the money you deposit. The account has no monthly fee, no minimum balance requirement, and no limit on how many times you can withdraw. You access it online through a website or mobile app, and you can transfer money in and out through ACH (the electronic system banks use to move funds between accounts).

The main draw is the interest rate. American Express advertises a rate that changes based on what the Federal Reserve does with its benchmark rate. When the Fed raises rates, American Express typically raises its savings rate within days. When the Fed cuts rates, the rate on the account drops. The actual rate varies — it is not locked in — so what you earn this month may differ from what you earn next month.

Money you deposit is insured by the FDIC up to $250,000 per account holder per bank. That means if American Express Bank fails, the government covers your balance up to that limit. If you have multiple accounts at American Express Bank (a savings account and a money market account, for example), the $250,000 limit applies across all of them combined.

Key Takeaways

  • The account earns interest that moves up or down with Federal Reserve rate changes, typically within days of an announcement.
  • You can deposit and withdraw money online or through ACH transfers, with no monthly fees or minimum balance.
  • Interest compounds daily and is deposited into your account monthly, so you earn interest on your interest.
  • Your deposits are FDIC insured up to $250,000, protecting your money if the bank fails.
  • You cannot write checks or use a debit card on this account — it is savings-only.

How interest accrues and when you see it in your account

Interest is calculated daily based on your balance. American Express divides the annual interest rate by 365 and multiplies it by the amount you have on deposit that day. That daily interest is added to your balance, and the next day, interest is calculated on the new, higher balance. This is called compounding, and it means your money grows faster than if interest were simply added once a year.

Interest is deposited into your account once a month, usually around the first of the month. You do not have to do anything to receive it — it appears automatically. Once it lands, it becomes part of your balance and earns interest itself the following month.

You can see your current balance and interest earned in the American Express mobile app or online portal. The app shows your year-to-date interest, so you can track how much you have earned since January.

How to move money in and out

You fund the account by linking it to a checking account at another bank and initiating an ACH transfer. ACH transfers typically take one to two business days to complete. You can also have your employer deposit your paycheck directly into the American Express savings account if you provide them with the routing number and account number.

To withdraw money, you initiate an ACH transfer from the American Express account back to your linked checking account. This also takes one to two business days. There is no limit on how many withdrawals you can make per month — unlike some savings accounts that cap transfers at six per month.

You cannot write checks on this account, and there is no debit card. If you need to spend the money, you have to transfer it to a checking account first, then use your debit card or checks from that account. This delay is intentional: it discourages frequent withdrawals and keeps the money in savings longer.

What happens when interest rates change

The Federal Reserve sets a target interest rate range that influences what banks pay on savings. When the Fed raises its rate, American Express typically raises the savings rate within one to three business days. When the Fed cuts rates, the American Express rate drops on the same timeline.

You do not have to do anything when the rate changes. The new rate applies automatically to your account. Your existing balance continues to earn interest at the new rate, and the change appears in your account details online.

The rate American Express offers is competitive with other online banks, but it changes frequently. If you are comparing this account to others, check the current rate on the day you are deciding, not a rate you saw a week ago. Rates move fast enough that a difference of 0.25% or 0.50% can appear or disappear in a matter of days.

Fees and account restrictions

There is no monthly maintenance fee, no minimum balance fee, and no fee for ACH transfers in or out. American Express does not charge you to open the account or to close it.

The account is limited to savings only. You cannot use it as a checking account, and you cannot link a debit card to it. If you need checking features, you would open a separate checking account at American Express or another bank.

If your account sits inactive (no deposits or withdrawals) for an extended period, American Express may close it. The bank will notify you before this happens and give you time to withdraw your money. Once closed, you would need to open a new account if you want to use American Express savings again.

How this account compares to a traditional bank savings account

A traditional bank (one with physical branches) typically pays much lower interest on savings accounts — often 0.01% or less. American Express Bank is online-only, which means it has lower overhead costs and can pass those savings to you in the form of higher interest rates. The tradeoff is that you cannot walk into a branch or speak to someone in person. All support is through phone, email, or the app.

American Express also offers a money market account, which works similarly but may have slightly different rate terms. Both are FDIC insured and both are interest-bearing, so the choice between them depends on whether you want the simplicity of a savings account or the flexibility of a money market account.

If you keep a large emergency fund or are saving for a specific goal, the higher interest rate on an American Express savings account means your money grows faster than it would at a traditional bank. Over a year, the difference can be hundreds of dollars on a $10,000 balance.

Tax reporting and what you owe on interest earned

Interest you earn on the account is taxable income. At the end of each year, American Express sends you a Form 1099-INT showing how much interest you earned. You report this amount on your tax return, and you owe federal income tax on it (and state income tax in most states).

The amount of tax you owe depends on your tax bracket. If you are in the 22% federal tax bracket and earn $100 in interest, you owe roughly $22 in federal tax on that interest. American Express does not withhold taxes automatically — you are responsible for reporting and paying.

If you earn less than $10 in interest during the year, American Express may not send you a 1099-INT, but you still owe tax on the interest. Keep your own records of interest earned if the amount is small.

Frequently Asked Questions

What is the current interest rate on an American Express savings account?

The rate changes based on Federal Reserve decisions and varies over time. Check the American Express website or app for the current rate on the day you are considering opening an account. Rates are typically updated within one to three business days of a Fed announcement.

Can I set up automatic transfers to save money each month?

Yes. You can schedule recurring ACH transfers from your linked checking account to the American Express savings account. Set it up in the app or online portal, and the transfer happens automatically on the date you choose each month.

What happens if I need to withdraw money urgently?

ACH transfers take one to two business days, so there is a delay. If you need cash immediately, you would need to transfer to a checking account first, then use an ATM or debit card. For true emergencies, keep a separate emergency fund in a checking account with immediate access.

Is my money safe if American Express Bank fails?

Yes. Your deposits are insured by the FDIC up to $250,000. If the bank fails, the FDIC covers your balance. This protection applies to each account holder separately, so if you and your spouse each have an account, you are each covered up to $250,000.

Can I have multiple savings accounts at American Express?

Yes, but the FDIC insurance limit applies across all accounts you hold at American Express Bank combined. If you have two savings accounts with $150,000 in each, only $250,000 total is insured. The remaining $50,000 is not covered.
