Call Comcast to cancel, and get your account number and final bill amount before you hang up
Comcast requires you to cancel by phone — there is no online cancellation option. Call 1-800-934-6489 and tell them you want to cancel your service. Have your account number ready (it is on your bill or in the Xfinity app). The representative will try to offer you a discount or a different plan; you can accept or decline, but you do not have to listen to the full pitch.
Before you end the call, write down three things: your cancellation date, your account number, and the final amount you owe. Ask the representative to email you a cancellation confirmation. This protects you if Comcast later claims you never called or charges you after your service ends.
Your service will stop on the date the representative gives you. If you have a cable box, modem, or router rented from Comcast, you will need to return it. Comcast will tell you where to drop it off or will arrange a pickup. If you do not return the equipment, Comcast will charge you a non-return fee, usually $100 to $200 per device.
Key Takeaways
- Call 1-800-934-6489 to cancel; Comcast does not allow cancellation online or through the app.
- Write down your cancellation date, account number, and final bill amount before hanging up, and ask for email confirmation.
- Return all rented equipment (cable box, modem, router) by your cancellation date or you will be charged a non-return fee.
- Your final bill may include prorated charges for the days you used service in your cancellation month, plus any equipment fees.
- Keep your cancellation confirmation and final bill for your records in case Comcast bills you after service ends.
What happens to your bill after cancellation
Comcast will send you a final bill within one to two billing cycles. This bill covers service through your cancellation date and may include a prorated charge if you cancelled mid-month. For example, if your bill cycle runs the 15th of each month and you cancel on the 25th, you will pay for 10 days of service on your final bill.
If you have a balance on your account — from a previous month or from equipment fees — Comcast will add that to your final bill. If you paid in advance for service you did not use, Comcast will issue a refund, but this can take several billing cycles to appear.
Some customers report being charged after cancellation. If this happens, call 1-800-934-6489 again with your cancellation confirmation number and ask them to reverse the charge. Having your written confirmation from the first call makes this easier.
Return your equipment on time to avoid extra charges
Comcast charges you a monthly rental fee for any equipment you use — typically $10 to $15 per month for a modem, $10 to $15 for a cable box, and $5 to $10 for a router. When you cancel, these fees stop, but only if you return the equipment.
The representative who processes your cancellation will tell you where to return equipment. You can usually drop it at an Xfinity store, a Comcast service center, or an authorized retailer. Some areas offer mail-in returns or scheduled pickups. Ask for the exact address or instructions before you hang up.
Keep your receipt or confirmation number from the return. If Comcast later charges you a non-return fee, you can dispute it by showing proof that you returned the equipment. Non-return fees range from $100 to $200 per device and can appear on your final bill or in a separate charge weeks later.
Cancel before your contract ends if you have an early termination fee
If you signed a contract with Comcast, cancelling before the contract ends may trigger an early termination fee. This fee is usually $100 to $240, depending on how much time is left on your contract. The representative will tell you the amount when you call to cancel.
You can choose to pay the fee and cancel anyway, or you can wait until your contract expires. Your contract end date is on your bill or in the Xfinity app. If you are close to the end date, it may be cheaper to wait a few weeks than to pay the termination fee.
Some customers have had early termination fees waived by asking to speak with a supervisor or by filing a complaint with the Federal Communications Commission (FCC). This does not always work, but it costs nothing to ask. If you decide to try, have your account number and cancellation confirmation ready.
What to do if you want to keep internet but cancel TV or phone
You do not have to cancel all your services at once. If you want to keep Xfinity internet but drop TV or phone, tell the representative which service you want to cancel. Comcast will adjust your bill to remove that service.
Your bill will likely go up when you remove a bundled service, because bundle discounts explore only when you have multiple services. For example, if you are paying $80 a month for internet, TV, and phone bundled together, cancelling TV and phone might raise your internet-only bill to $70 or $80 per month, depending on your plan and location.
Ask the representative what your new bill will be before you confirm the cancellation. If the price is too high, you can cancel all services instead, or you can ask about other plans or discounts.
Switch to a different internet provider before your Comcast service ends
Comcast service can take a few days to fully disconnect after your cancellation date. If you have ordered service from another provider, schedule the new service to start a few days after your Comcast cancellation date. This gives you a small window of overlap so you do not lose internet access.
When the new provider installs service, they will give you a modem and router (or you can use your own, depending on the provider). You will not need Comcast equipment anymore, so return it as soon as your new service is working.
If you are switching from Comcast phone service, update your phone number with your bank, insurance company, doctor, and any other important contacts before you cancel. Comcast will not port your number to another provider, so you will need a new number from your new phone service provider.
Frequently Asked Questions
Can I cancel Xfinity online or through the app?
No. Comcast requires cancellation by phone. Call 1-800-934-6489. The Xfinity app and website do not have a cancellation option. Some third-party sites claim to cancel Comcast for you, but Comcast does not recognize these cancellations, so you will still be billed.
What if I am on a promotional rate and it is about to expire?
If your promotional rate is ending and your bill is about to jump, call 1-800-934-6489 before you cancel. Ask if they have other promotions or plans available. Sometimes representatives will offer a new promotion to keep you as a customer. If not, you can cancel and switch to another provider.
Do I have to pay my final bill right away?
No. Comcast will send you an invoice, and you can pay it by the due date shown on the bill, usually 20 to 30 days after the bill is issued. If you do not pay, Comcast may send your account to collections, which can affect your credit score.
What if Comcast keeps charging me after I cancel?
Call 1-800-934-6489 with your cancellation confirmation number and ask them to reverse the charge. If they refuse or if the charges continue, file a complaint with the FCC at fcc.gov/complaints or with your state's attorney general. Keep copies of your cancellation confirmation and all bills showing charges after your cancellation date.
Can I get a refund for unused service?
If you paid in advance for service you did not use, Comcast will refund the amount. Refunds usually appear as a credit on your final bill or as a separate check mailed to you, but can take several billing cycles. If you do not see a refund within 60 days, call 1-800-934-6489 to ask about it.
