Pay Your American Express Bill Through the Website or Mobile App
You can pay your American Express card bill online through amex.com or the American Express mobile app. Log in with your username and password, go to the payment section, enter the amount you want to pay, and choose your payment date. The payment posts to your account within one business day in most cases.
American Express does not charge a fee for online payments made from a U.S. bank account. If you pay from an international bank account or use a money transfer service, American Express may charge a fee — check the payment screen before you confirm.
You can set up a one-time payment or a recurring automatic payment. Automatic payments deduct from your bank account on the date you choose each month, which helps you avoid late fees if you set the date before your statement due date.

How to Make a One-Time Payment Online
Start by visiting amex.com and signing in with your username and password. If you do not have an online account yet, you will need to register using your card number and other identifying information.
Once you are logged in, look for a "Pay" or "Make a Payment" button, usually near the top of the page or in the account menu. Click it and enter the amount you want to pay. You can pay your full balance, the minimum payment, or any amount in between.
Next, select the date you want the payment to be deducted from your bank account. American Express will show you the date the payment will post to your card. Review all the details, confirm your bank account information is correct, and submit the payment. You will receive a confirmation number on screen and by email.
Setting Up Automatic Monthly Payments
Automatic payments remove the risk of forgetting to pay and can help you avoid late fees. To set this up, log into your account and find the autopay or automatic payment section, usually under settings or payment options.
Choose the amount you want to pay each month: your full statement balance, a fixed dollar amount, or your minimum payment. Then select the day of the month you want the payment to come out of your bank account. Most cardholders choose a date shortly after they receive their statement, so they know the balance they are paying.
You can change or cancel automatic payments at any time through your online account. If you need to stop a payment before it processes, log in and turn off autopay at least one business day before the scheduled payment date.
Paying Through the American Express Mobile App
The American Express mobile app works the same way as the website. read the app from the Apple App Store or Google Play, sign in with your username and password, and tap the payment option.
Enter your payment amount and choose your payment date. The app will confirm your bank account information and show you when the payment will post. Tap to submit, and you will see a confirmation number. Payments made through the app post on the same timeline as website payments — usually within one business day.
The mobile app also lets you view your statement, check your balance, and manage automatic payments on the go. You can set up or change autopay settings directly from the app.
What Happens If You Miss Your Due Date
If your payment does not arrive by your statement due date, American Express will charge a late fee. The amount depends on your card type and account history, but late fees typically range from $25 to $40 for the first late payment.
A late payment also appears on your credit report and can lower your credit score. If you realize you will miss the due date, log in and make a payment as soon as you can. Even a payment after the due date stops additional late fees from building up.
If you have autopay turned on, your payment will post on your chosen date even if that date is after your statement due date. To avoid late fees with autopay, choose a payment date that falls before your due date — usually within a few days of receiving your statement.
Paying by Phone or Mail If You Cannot Pay Online
If you do not have internet access or prefer not to pay online, you can pay by phone. Call the number on the back of your American Express card and follow the prompts to make a payment. You will need your card number and bank account information ready. Phone payments are free and post within one business day, the same as online payments.
You can also mail a check to the address shown on your statement. Write your account number on the check and mail it to the payment address listed in your billing materials. Mailed payments take longer to post — usually 7 to 10 business days — so send your check early if your due date is coming up.
Do not send cash through the mail. If you need to pay in person, visit an American Express office or authorized payment location in your area, though this option is limited and not available everywhere.
Frequently Asked Questions
How long does it take for an online payment to show up on my account?
Payments made online from a U.S. bank account usually post within one business day. Payments made on a weekend or holiday may take until the next business day. You will see a confirmation number when ready after you submit, and you can check your account balance online to confirm the payment has posted.
Can I pay my American Express bill with a credit card or debit card?
American Express only accepts payments from a bank account (checking or savings), not from another credit card or debit card. This is a standard policy across most credit card companies. You can link multiple bank accounts to your American Express profile if you want to pay from different accounts.
What if I pay more than my current balance?
If you pay more than you owe, the extra amount becomes a credit on your account. You can use this credit toward future purchases, or you can request a refund. To request a refund, log into your account or call the number on the back of your card and ask for the overpayment to be returned to your bank account.
Is there a maximum amount I can pay online?
American Express does not publish a specific online payment limit, but very large payments may trigger a security review. If your payment is declined, call the number on the back of your card to confirm the payment by phone, or try paying a smaller amount online and making a second payment the next day.
Can I schedule a payment for a future date more than a month away?
Most online payment systems only let you schedule payments a few weeks in advance. If you want to set up a payment far in the future, use automatic payments instead and set them to begin on the date you choose. You can always cancel or adjust automatic payments later if your situation changes.
