The fastest way to pay Comcast online

Go to www.comcast.com/pay and sign in with your Comcast username and password. Once logged in, you'll see your current balance and due date. You can pay the full amount, a partial payment, or set up automatic payments from a bank account or debit card. The payment posts immediately to your account, though it may take one to two business days to show as cleared on your bank statement.

If you don't remember your username or password, use the "Forgot username or password?" link on the login page. Comcast will send a reset link to the email address on file. Keep your login information saved in your browser's password manager so you don't have to look it up each time.

The Xfinity mobile app also lets you pay your bill. Download the app, sign in, and tap the bill or account section. The process is identical to the website, and payments made through the app post the same way.

Key Takeaways

  • Pay online at www.comcast.com/pay by signing in with your Comcast username and password, and the payment posts immediately.
  • Set up automatic payments through the website or app so your bill is paid on the same date each month without you having to log in.
  • You can pay by phone at 1-800-COMCAST (1-800-266-2278) if you prefer to speak with someone or don't have internet access.
  • Mail payments to the address on your bill, but allow 7 to 10 business days for the payment to reach Comcast and post to your account.
  • Late fees apply if your payment doesn't post by the due date shown on your bill, regardless of when you sent it.

Setting up automatic payments so you never miss a due date

Automatic payments remove the need to remember to pay each month. On www.comcast.com/pay, after you sign in, look for the "Autopay" or "Automatic Payment" option. You'll enter a bank account or debit card number, choose the date the payment should come out each month, and confirm. Comcast will deduct the full bill amount on that date every month unless you change or cancel the setup.

If your bill amount varies month to month (for example, if you use pay-per-view or have a promotional rate that's ending), automatic payments still work—Comcast charges whatever the current bill is on the date you set. You can pause or cancel automatic payments anytime through your account settings.

Automatic payments are the safest way to avoid late fees, because the payment is may provide to post by your due date. If you're worried about overdrafts, check your bank balance before the payment date, or choose a date a few days after you normally get paid.

Paying by phone or mail if you can't pay online

Call 1-800-COMCAST (1-800-266-2278) to pay over the phone. A representative will ask for your account number (on your bill) and the payment method—debit card, credit card, or bank account. The call typically takes 5 to 10 minutes. Payments made by phone post the same day, just like online payments.

If you prefer to mail a check or money order, write your account number on the back and send it to the address printed on your bill. Do not send cash. Allow 7 to 10 business days for the payment to arrive and post. If your due date is fewer than 10 days away, mailing is risky—use online payment or phone payment instead to avoid a late fee.

Some Comcast service centers accept in-person payments, though this is less common than it once was. Call 1-800-COMCAST to ask if there's a payment center near you.

Understanding your due date and late fees

Your due date appears on your bill and in your online account. Comcast considers a payment late if it doesn't post to your account by 11:59 p.m. on that date. Online and phone payments post the same day, so paying before midnight on the due date keeps you on time. Mailed payments are judged by the date they arrive at Comcast, not the date you mail them.

Late fees vary by state and service type, but typically range from $5 to $10 for the first late payment. If your account stays past due for 30 days, Comcast may suspend your service. If it stays unpaid for 60 days, they may terminate your account and refer it to a collection agency, which damages your credit score.

If you're having trouble paying on time, call 1-800-COMCAST to ask about payment plans or hardship programs. Comcast sometimes offers temporary extensions or reduced payment schedules for customers facing financial hardship.

What to do if your payment doesn't show up in your account

If you paid online or by phone and the payment hasn't posted within one business day, log back into www.comcast.com/pay and check your account balance. Most payments appear within hours. If more than one business day has passed and the payment still doesn't show, call 1-800-COMCAST with your confirmation number (which you should have received by email after paying online, or been given during the phone call).

If you mailed a check and it's been more than 10 business days, call Comcast with the date you mailed it and the amount. They can search their records to see if the payment arrived. If it's lost in the mail, Comcast may ask you to stop payment on the original check and send a new one, or pay again online.

Keep your payment confirmation email or receipt for at least 60 days. If there's a dispute about whether a payment posted, this proof protects you.

Paying a past-due balance or reconnection fee

If your account is past due, you'll see the overdue amount when you log into www.comcast.com/pay. You can pay the past-due balance in full, or call 1-800-COMCAST to negotiate a payment plan if the amount is large. Paying the past-due balance doesn't stop a late fee that's already been added—that fee is separate.

If your service was suspended for non-payment, you'll also owe a reconnection fee (typically $15 to $30, depending on your state) before service is restored. This fee is added to your bill and must be paid before Comcast will turn your service back on. Pay online, by phone, or in person at a service center. Reconnection usually happens within 24 hours of payment.

If you're unable to pay a large past-due balance, ask Comcast about their hardship program or payment arrangement options. Some regions offer programs that reduce or waive fees for customers in financial difficulty.

Frequently Asked Questions

Can I pay my Comcast bill with a credit card online?

Yes. At www.comcast.com/pay, you can enter a Visa, Mastercard, American Express, or Discover card. Comcast also accepts debit cards. Note that if you use a credit card, your credit card company may charge you a cash advance fee or treat it as a purchase—check your card's terms.

What if I don't have a Comcast username yet?

If you've never logged into your Comcast account online, go to www.comcast.com and click "Sign In" in the top right. Then click "Create one now" or "Forgot username?" to set up an account. You'll need your account number (from your bill) and the phone number or email on file. Once your account is created, you can pay at www.comcast.com/pay.

Is it safe to pay my Comcast bill online?

Yes. Comcast uses encryption and security measures to protect your payment information. Only enter your payment details on www.comcast.com or the official Xfinity app—never through a link in an email or text, even if it looks like it came from Comcast. Scammers sometimes send fake payment emails to steal information.

How long does it take for automatic payments to start?

Automatic payments typically begin on the date you choose during setup, which is usually your next billing cycle. If you set it up a few days before your due date, the first automatic payment may not go through until the following month. Check your account settings to see when the first payment is scheduled.

Can I change my due date?

Yes. Log into www.comcast.com/pay, go to your account settings or billing preferences, and look for "Change Due Date" or "Billing Date." You can usually choose any date between the 1st and the 28th of the month. The change takes effect on your next billing cycle.
