Comcast internet pricing starts at $30 per month for the slowest plan and goes up to $120 or more for gigabit speeds, but the actual price you pay depends on your location, current promotions, and whether you bundle with TV or phone service.

Comcast (also branded as Xfinity) publishes starting prices, but those rates typically apply only for the first 12 months. After that, the price increases — sometimes significantly. The company also runs different promotions in different areas, so two people in the same city might see different offers. Your best approach is to enter your address on Comcast's website or call 1-800-934-6489 to see what plans and prices are actually available where you live.

Comcast charges separately for internet, TV, and phone service, though bundling two or all three usually costs less than buying them individually. If you only want internet, you can order that alone. The company also charges a modem rental fee (typically $14 per month) unless you buy your own compatible modem, which costs $100 to $200 upfront but saves money over time.

Key Takeaways

  • Comcast internet prices range from $30 to $120+ per month depending on speed tier, location, and promotions, with prices rising after the first year.
  • You can check what plans and prices are available at your specific address by visiting Comcast's website or calling their sales line.
  • Renting a modem costs about $14 per month, but buying one for $100 to $200 saves money if you plan to stay with Comcast for more than a year.
  • Bundling internet with TV or phone service usually costs less than ordering internet alone, though you pay for services you may not use.

Speed tiers and what they cost

Comcast typically offers four main internet speed tiers: 50 Mbps, 100 Mbps, 300 Mbps, and 1000 Mbps (gigabit). The 50 Mbps plan is the entry-level option and usually carries the lowest advertised price. Each step up in speed adds $20 to $30 per month to the base cost. The gigabit plan is the fastest and most expensive, though it is still slower than fiber internet where available.

The speed you choose should match how you use the internet. 50 Mbps works for one or two people browsing, streaming video, and checking email. 100 Mbps handles a household of three to four people doing multiple things at once. 300 Mbps and gigabit are for households with heavy users, people working from home on video calls, or homes with many connected devices. Comcast's website includes a speed recommendation tool that asks about your household size and usage.

Promotional pricing versus regular rates

Comcast advertises low introductory rates that last 12 months. When that period ends, your bill jumps to the regular price, which is usually $20 to $40 higher per month. For example, a plan advertised at $50 per month might jump to $85 after year one. The company sends a notice before the increase takes effect, but many customers are surprised by the jump.

To avoid sticker shock, ask the sales representative what the regular price will be before you sign up. Some customers call back after 12 months to negotiate a lower rate or switch to a competitor's promotion. Comcast sometimes offers discounts to long-term customers or those who bundle services, so it is worth asking what options exist when your promotional period ends.

Modem rental fees and the cost of buying your own

Comcast charges a modem rental fee of approximately $14 per month. This fee appears on your bill separately from your internet service charge. If you rent a modem for two years, you pay roughly $336 in rental fees. A compatible modem that you buy outright costs between $100 and $200, depending on the model and where you purchase it.

Buying a modem makes financial sense if you plan to stay with Comcast for more than 18 months. You own the equipment, so you can take it with you if you move (as long as your new address has Comcast service). Comcast publishes a list of compatible modems on its website; popular models include the Netgear CM500 and the ARRIS SB6121. If you buy a modem, you still need to register it with Comcast before it will work on their network.

Bundling discounts and package deals

Comcast offers discounts when you bundle internet with TV service, phone service, or both. A bundle might cost less than ordering each service separately, but the savings apply only during the promotional period. After 12 months, the bundle price also increases. The discount is most significant when you add phone service to internet and TV, sometimes saving $20 to $30 per month during the first year.

Bundling makes sense only if you actually want all the services included. If you only need internet, ordering internet alone is usually cheaper than paying for a bundle and not using the TV or phone portion. Comcast's website shows bundle pricing for your address, and you can compare the cost of bundled versus standalone internet to see which is cheaper for your situation.

Data caps and overage charges

Comcast imposes a 1.2 terabyte (TB) monthly data cap on most residential internet plans. That is roughly equivalent to streaming 4K video for 12 hours per day, every day of the month. Most households stay well under this limit. If you exceed the cap, Comcast charges an overage fee, typically $10 per 50 GB over the limit, up to a maximum of $200 per month.

You can check your data usage through the Xfinity app or online account portal. If you consistently approach or exceed the cap, you can pay an additional $30 to $50 per month to remove the cap entirely. This option is worth considering if you have many people in your household, work from home with large file transfers, or stream video frequently.

Installation fees and equipment costs

Comcast charges a one-time installation fee when you set up service, typically $99 to $199 depending on whether a technician needs to visit your home or if you self-install using equipment they mail to you. Self-installation is free or low-cost if you have an existing coaxial cable outlet in your home. A technician visit costs more but includes setup, testing, and troubleshooting.

Some Comcast promotions waive the installation fee, so ask whether it is included in the offer you are seeing. If you already have a compatible modem and do not need a technician, self-installation can save you $100 or more. Comcast provides instructions and a self-installation kit that includes a modem and any cables you need.

How to find current pricing for your address

Comcast's advertised prices vary by location and change frequently based on promotions. The only way to see what you will actually pay is to enter your address on Comcast's website (xfinity.com) or call 1-800-934-6489. Both methods show you available plans, speeds, and prices specific to your location.

When you check pricing, you will see the promotional rate (usually for 12 months) and the regular rate that applies after. Write down both numbers so you know what to expect when your promotional period ends. If the regular price is higher than you want to pay, ask the sales representative whether they can extend the promotional rate or offer a different discount.

Frequently Asked Questions

Can I use my own modem with Comcast?

Yes, as long as it is compatible with Comcast's network. Comcast publishes a list of approved modems on its website. You must register your modem with Comcast before it will work. Buying your own modem saves money compared to renting, especially if you keep it for more than 18 months.

What happens to my bill after the first year?

Your promotional rate expires and the price increases to the regular rate, which is typically $20 to $40 higher per month. Comcast sends a notice before the increase takes effect. You can call to negotiate a lower rate, switch to a different plan, or move to a competitor.

Is Comcast internet available at my address?

Enter your address on xfinity.com or call 1-800-934-6489 to check. Comcast serves most urban and suburban areas but not all rural locations. If Comcast is not available, the site will show other providers that serve your address.

What is the difference between Comcast and Xfinity?

Xfinity is Comcast's consumer brand name. They are the same company. Comcast is the corporate name, and Xfinity is what you see on bills, websites, and customer service materials.

Do I have to buy a bundle, or can I get internet only?

You can order internet alone without TV or phone service. Internet-only plans are available at most Comcast locations. Bundling usually costs less per service, but only if you use all the services included.
