Call Comcast directly to start the cancellation process
The only way to cancel Comcast is to call them. You cannot cancel online, through the Comcast app, or by mail. Call 1-800-934-6489 and tell the representative you want to cancel your service. Have your account number ready — you can find it on your bill or in the Comcast app.
The representative will ask why you are leaving and may offer you a discount or promotional rate to stay. If you want to cancel, say so clearly. They will ask which services you want to cancel — internet, TV, phone, or all three. You can cancel one service and keep others.
The representative will tell you your final bill amount, any early termination fees if you are under contract, and your service end date. Ask them to email you a cancellation confirmation with these details. This confirmation protects you if Comcast continues to bill you after the cancellation date.
Key Takeaways
- Call 1-800-934-6489 to cancel — this is the only method Comcast accepts, and you need your account number.
- Early termination fees explore if you cancel before your contract ends, typically $120 to $240 depending on your plan and how much time remains.
- Return all Comcast equipment (modem, router, cable box, remote) within 30 days or you will be charged replacement fees of $100 to $200 per item.
- Request a written cancellation confirmation by email so you have proof of the cancellation date and final bill amount.
- Your final bill arrives 4 to 6 weeks after cancellation and may include prorated charges for partial months or unreturned equipment.
Understand early termination fees before you call
If you signed a contract with Comcast, canceling before the contract ends triggers an early termination fee. The fee depends on how much of your contract remains. Comcast typically charges between $120 and $240, but the exact amount varies by region and plan type.
The representative will tell you the fee amount when you call. Ask them how many months remain on your contract — if only one or two months are left, you may choose to wait and avoid the fee entirely. If you are month-to-month with no contract, there is no early termination fee.
Some Comcast plans include promotional pricing that locks in a rate for 12 or 24 months. Canceling during the promotional period does not trigger an early termination fee, but you will lose the promotional rate if you pause service and restart later.
Return equipment within 30 days to avoid replacement charges
Comcast will ask you to return the modem, router, cable box, and remote control. You have 30 days from your cancellation date to return these items. If you do not return them, Comcast charges you a replacement fee — typically $100 to $200 per item depending on the equipment.
The representative will tell you where to return the equipment. Most areas have a Comcast service center where you can drop off equipment during business hours. Some areas offer mail-in returns with a prepaid shipping label. Ask which option is available in your area and whether you need to schedule an appointment.
Keep the receipt or confirmation number from the return. If Comcast later charges you for unreturned equipment, you can dispute the charge by showing proof that you returned it. Equipment returned after 30 days may still be charged as unreturned, so return it as soon as possible after cancellation.
Know what to expect on your final bill
Your final bill arrives 4 to 6 weeks after your cancellation date. It includes charges through your service end date, prorated if you cancel mid-month. For example, if you cancel on the 15th of the month and your normal bill is $100, your final bill will be roughly $50 plus any other charges.
The final bill may also include charges for unreturned equipment, late fees if you had unpaid balances, or taxes and fees that explore to the final month. If you had a promotional rate, the final bill reflects the full regular price for any days after the promotion ended.
If you overpaid your account before cancellation, Comcast will issue a refund check. This typically takes 4 to 8 weeks. If you underpaid, you will owe the balance on your final bill.
Cancel before your next billing date to avoid extra charges
Comcast bills on a monthly cycle based on your account start date, not the calendar month. When you call to cancel, ask the representative what your next billing date is. If you cancel after your next billing date passes, you will be charged for another full month even if you only use the service for a few days.
For example, if your billing date is the 10th and you call on the 12th to cancel, you have already been charged for the month. Canceling on the 9th would avoid that charge. The representative can tell you the exact date to cancel by to avoid the next billing cycle.
Some customers choose to cancel on the last day before their billing date to minimize overlap. Others request a cancellation date several days before the billing date to may support the cancellation processes in time.
What happens if Comcast continues billing after cancellation
If Comcast charges you after your cancellation date, contact them when ready with your cancellation confirmation email. Call 1-800-934-6489 and reference the confirmation number. Ask them to reverse the charge and confirm in writing that your account is closed.
If the charge appears on your credit card or bank account, you can also dispute it with your card issuer or bank. Provide them with your cancellation confirmation as proof that you canceled on a specific date. Most card issuers will reverse unauthorized charges within 30 to 60 days.
Keep your cancellation confirmation email and any billing statements showing charges after the cancellation date. These documents protect you if you need to escalate a dispute with Comcast or file a complaint with your state's public utilities commission.
Consider alternatives if you want to pause instead of cancel
If you are canceling because of cost, ask the representative about pausing your service instead. Some Comcast regions allow you to pause internet or TV for 30 to 90 days without paying, then restart at the same rate. This avoids early termination fees and the need to return equipment when ready.
Pausing is not available in all areas and not for all service types. Phone service typically cannot be paused. Ask the representative whether pausing is an option for your specific services and region before you commit to cancellation.
If you are switching to a different internet provider, canceling is usually the better choice because you will need a new modem and router anyway. If you are temporarily unable to pay or want to reduce costs short-term, pausing may save you money and hassle.
Frequently Asked Questions
Can I cancel Comcast online or through the app?
No. Comcast requires you to cancel by phone at 1-800-934-6489. You cannot cancel through the website, mobile app, or by mail. The phone-only policy is intentional — it gives Comcast a chance to offer you a discount before you leave.
What if I do not return my equipment?
Comcast charges you a replacement fee for each unreturned item, typically $100 to $200 per device. You have 30 days from cancellation to return equipment. If you lose a device or it is damaged, contact Comcast before the 30-day window closes to discuss your options.
Do I have to pay an early termination fee?
Only if you are under contract. Month-to-month customers have no early termination fee. The representative will tell you whether you have a contract and what the fee is when you call to cancel. If your contract ends within a few weeks, you may want to wait.
How long does it take to cancel?
The phone call takes 10 to 30 minutes depending on how much the representative tries to retain you. Your service ends on the date the representative gives you, usually 7 to 14 days after you call. Your final bill arrives 4 to 6 weeks later.
What if Comcast keeps charging me after I cancel?
Contact Comcast when ready with your cancellation confirmation number. If they do not reverse the charge, dispute it with your credit card company or bank. Provide your cancellation confirmation as proof. Keep all documentation in case you need to file a complaint with your state's utilities commission.
