How 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 the website or app — both let you pay in minutes and show your balance and due date when ready. If you prefer speaking to someone, American Express customer service can process a payment over the phone. Mail payments take 7 to 10 business days to reach them, so send early if your due date is near.
American Express requires at least a minimum payment by your due date each month. The minimum is usually 1% to 3% of your balance, but paying only the minimum means you carry a balance and pay interest. Paying your full statement balance by the due date avoids interest charges entirely.
Key Takeaways
- Pay through amex.com, the American Express mobile app, by phone at the number on your card, or by mailing a check to the address on your statement.
- Your due date appears on your monthly statement and in your online account — missing it triggers a late fee and may raise your interest rate.
- Paying your full statement balance by the due date costs no interest; paying only the minimum means you carry a balance and pay interest on it.
- You can set up automatic payments from your bank account to pay a fixed amount or your full balance each month.
- American Express charges a late fee if your payment arrives after the due date, even by one day.
Paying online or through the mobile app
Log into your American Express account at amex.com or open the American Express mobile app. Select "Make a Payment" or "Pay Bill" — the exact wording varies by card type. Enter the amount you want to pay and confirm your bank account or debit card details. The payment processes when ready, though it may take one to two business days to show as posted on your account.
The website and app both show your current balance, minimum payment due, and due date. You can pay any amount between the minimum and your full balance. If you want to pay more than your current statement balance — for example, to pay down a previous balance you carried — you can do that too.
Setting up automatic payments
Automatic payments remove the risk of missing a due date. In your American Express account, go to "Manage Automatic Payments" or "Autopay Settings" and link a bank account. You can choose to pay a fixed dollar amount each month, your minimum payment, or your full statement balance.
If you choose to autopay your full balance, the payment triggers a few days before your due date. This means you pay no interest and never carry a balance. If you choose a fixed amount or minimum payment, you remain responsible for any balance that exceeds the payment — interest accrues on that amount.
Paying by phone or mail
Call the number on the back of your card to pay by phone. A representative will ask for the amount and your bank account or debit card details. The payment processes when ready over the phone, though posting to your account takes one to two business days.
To pay by mail, write a check and mail it to the address shown on your statement. Include your account number on the check. Mail payments take 7 to 10 business days to arrive, so send at least two weeks before your due date to avoid a late fee. American Express processes mail payments in the order received, so early arrival matters.
Understanding your due date and late fees
Your due date is the same day each month and appears on your statement and in your online account. American Express considers a payment late if it arrives after 11:59 p.m. on that date. A late payment triggers a late fee — the amount depends on your card type and account history, but typically ranges from $25 to $40 for the first late payment.
A late payment also may raise your interest rate. American Express can increase your rate if you miss a due date, and the higher rate applies to any new purchases and carried balances. Paying on time protects both your account and your credit score, which is reported to the three credit bureaus.
What to do if you cannot pay by the due date
If you know you cannot pay by your due date, contact American Express before the date arrives. Explain your situation — they may offer a short extension, a temporary lower payment, or a plan to catch up. Calling ahead is far better than missing the due date, because it shows good faith and may prevent a late fee.
If you have already missed a payment, call American Express when ready. The sooner you pay, the less damage to your credit score. A single late payment stays on your credit report for seven years, but its impact fades over time, especially if you pay on time going forward.
Frequently Asked Questions
How long does it take for my payment to show up?
Online and app payments post within one to two business days. Phone payments post the same way. Mail payments take 7 to 10 business days. American Express counts a payment as on time if it arrives by 11:59 p.m. on your due date, so mail early if you use that method.
Can I pay more than my statement balance?
Yes. You can pay any amount, including more than you owe. Overpayments create a credit on your account that offsets future charges. You can also request a refund of any credit balance, though it may take a few business days to process.
What happens if I pay only the minimum?
You avoid a late fee and protect your credit score, but you carry the remaining balance into the next month. Interest accrues on that balance at your card's annual percentage rate (APR). Paying only the minimum means you pay more in total interest over time.
Is there a fee to pay my bill?
No. American Express does not charge a fee for paying your bill through their website, app, or by phone. Paying by mail costs only the price of a stamp. Some third-party payment services may charge a fee, but American Express's own payment methods are free.
Can I change my due date?
Yes. Log into your American Express account and look for "Change Due Date" or "Manage Account Settings." You can move your due date to a different day of the month, which may help you align payments with your paycheck or budget cycle.
