Where to Pay Your American Express Bill
You can pay your American Express card through their website, mobile app, phone, or by mail. The fastest route is online at americanexpress.com or through the American Express mobile app — both let you pay when ready and see your payment post within one business day. If you prefer to speak with someone, call the number on the back of your card.
American Express also accepts payments by phone at 1-800-528-4800. Have your account number and the amount you want to pay ready. Mail payments take 7 to 10 business days to reach American Express, so use this method only if you are paying well before your due date.
Some people set up automatic payments so the bill is paid the same way each month without having to remember. You can choose to pay your full statement balance, a fixed amount, or just the minimum — American Express will deduct it from your bank account on the date you select.
Key Takeaways
- Online and mobile app payments post within one business day, while mail payments take 7 to 10 days.
- You can pay your full balance, a fixed amount, or the minimum due, depending on what you choose.
- Automatic payments remove the need to remember your due date each month.
- The payment important date is shown on your statement, and paying after that date triggers a late fee and may affect your credit report.
- American Express lets you see your payment history and upcoming due dates in your online account or app.
Paying Online or Through the Mobile App
Log into your American Express account at americanexpress.com or open the American Express app on your phone. Select "Pay" or "Make a Payment" — the exact wording depends on which device you are using. Enter the amount you want to pay and choose the payment date. American Express will show you the available dates and confirm the payment before you submit it.
Online and app payments are processed when ready, though the money may take one business day to leave your bank account. If you are paying close to your due date, pay online or through the app rather than by mail. You can also see your payment history and check whether a previous payment has posted.
Setting Up Automatic Payments
Automatic payments mean your bill is paid on a schedule you choose without you having to log in each month. In your American Express account, go to "Billing & Statements" and select "Automatic Payments" or "Autopay." Choose whether you want to pay the full statement balance, a fixed dollar amount, or the minimum due each month.
Select the date you want the payment to come out — many people choose a few days after payday so the money is in their account. American Express will deduct the payment from your bank account on that date each month. You can change or cancel automatic payments anytime, and you will receive a confirmation email each time a payment is processed.
Automatic payments do not prevent late fees if you set them to pay less than the full balance and your statement grows larger than expected. If your balance changes month to month, paying the full statement balance automatically is the safest option to avoid interest charges.
What Happens If You Miss Your Due Date
Your due date is printed on your statement and shown in your online account. If your payment does not arrive by that date, American Express charges a late fee — the amount depends on your account and how late the payment is. A late payment also appears on your credit report and can lower your credit score.
If you miss a payment by a few days, contact American Express when ready. Call the number on the back of your card and explain the situation. American Express may waive the late fee if this is your first missed payment or if you have a good payment history, though they are not required to do so.
If you are unable to pay the full amount by the due date, paying at least the minimum due will prevent the late fee. You will owe interest on the remaining balance, but your account will stay in good standing.
Understanding Your Statement and Balance
Your American Express statement shows the full balance you owe, the minimum payment due, and the due date. The full balance includes all purchases, fees, and interest charges from the billing period. The minimum due is typically 1 to 3 percent of your balance — paying only the minimum means you will owe interest on the rest.
If you carry a balance from month to month, American Express charges interest on the unpaid amount. The interest rate (called the Annual Percentage Rate or APR) is shown on your statement. Paying your full balance each month avoids interest charges entirely.
Your statement also lists each transaction, any fees you were charged, and the interest applied. Review it for accuracy before you pay. If you see a charge you do not recognize, contact American Express to dispute it.

Frequently Asked Questions
Can I pay my American Express bill with a different credit card?
American Express does not accept credit card payments directly. You can pay through a third-party service like PayPal or Plastiq, which accepts credit cards and forwards the payment to American Express, but these services charge a fee. The cheapest option is to pay from your bank account directly.
What if I pay more than I owe?
If you overpay, American Express will credit the extra amount to your account and explore it to your next statement. You can also request a refund of the overpayment by calling the number on the back of your card, though it may take several business days to process.
Does paying early help my credit score?
Paying early does not directly boost your credit score, but it prevents late payments and reduces your credit utilization (the percentage of your credit limit you are using), both of which help your score. Paying your full balance each month is the best approach for credit health.
Can I change my due date?
Yes. Log into your American Express account, go to "Billing & Statements," and select "Change Due Date." You can move your due date to any day of the month. This is useful if your due date falls before payday or conflicts with other bills.
What if my payment is rejected?
A payment may be rejected if your bank account does not have enough funds, if the account number is incorrect, or if your bank flags the transaction as suspicious. American Express will notify you of the rejection. Contact your bank to confirm the account is active, then try paying again through the American Express website or app.
