A good home internet plan is borderline essential these days, so if you’re shopping around for a new one, you’ve got a lot to think about. Beyond understanding how the different technologies at play might affect your network performance and determining how much speed you actually need, you might consider looking into the discounts that are available for low-income households, or bundling your home internet with other services.

Outside of that, you’ll want some familiarity with the companies competing for your business, too. Among them, two of the largest are Comcast Xfinity, which is available to roughly one-third of American households, and Verizon Fios, available to a little over one-sixth of the country. If you live in the Northeast, you might even have access to both.

If that’s the case, you’ve come to the right post. Below, we’ll take a look at how the two providers stack up, from speeds and price tiers to coverage maps and customer satisfaction.

Technology and speeds

From fiber to satellite, dial-up to DSL, there are lots of different ways for ISPs to get internet connectivity into people’s homes. While a lot of internet providers employ a mix of methods as needed to get as many people online as possible, most focus on one main technology for a majority of customers. For instance, Comcast’s Xfinity internet service specializes in cable internet, which carries your web traffic along the same copper coaxial wiring that delivers cable TV into peoples’ homes. That’s no surprise — along with being an internet juggernaut, Comcast is one of the biggest cable TV providers in the US

According to the Federal Communications Commission’s most recent data (an admittedly flawed and outdated database, even according to FCC commissioners), cable internet accounts for 99.98% of Xfinity’s subscriber footprint, with download speeds of up to 500Mbps. The other 0.02% of Xfinity subscribers receive their internet via a faster fiber connection, the FCC says. Comcast disputes those figures as out of date, though, and says that gigabit download speeds are now available to the vast majority of Xfinity subscribers.

“As of January 2021, Comcast upgraded its Xfinity Gigabit Internet speed to provide 1.2Gbps (1,200Mbps) in its Northeast Division,” a Comcast spokesperson tells CNET. “The company will roll out this speed increase across the rest of its footprint throughout 2021. Xfinity Gigabit Internet is available to 99-plus% of its footprint.”

Upload speeds are another story. While Xfinity offers fast downloads, upload speeds with those 1.2Gbps plans typically top out at around 35Mbps, which is roughly the bare minimum for HD video conferencing. Lower-tier plans offer even less. For instance, if you subscribe to Xfinity’s Blast! plan with download speeds of 300Mbps, your accompanying upload speeds will be capped at just 10Mbps. And no, Comcast isn’t close to clear about this shortcoming on its website, or in any of its advertising for Xfinity service.

Faster upload speeds do seem to be in the works, but it’s unclear when a majority of Xfinity customers should expect to benefit from them.

“Over the years, we have consistently increased both upstream and downstream speeds,” a Comcast spokesperson says, while also pointing to an in-house report showing that downstream traffic was roughly 14 times higher than upstream traffic in 2020. 

“We continue to evaluate usage, but nothing to announce about increases to our upstream speeds at this time,” the spokesperson adds.

Comcast Xfinity Home Internet Plans

Package (download/upload) Typical monthly cost
25Mbps / 3Mbps $20-$25
100Mbps / 5Mbps $35-$45
200Mbps / 5Mbps $40-$60
300-400Mbps / 10Mbps $60-70
600Mbps / 15Mbps $70-$80
1.0Gbps (1.2Gbps in Northeast) / 35Mbps $80-$90
2.0Gbps / 2.0Gbps $300

Verizon Fios Home Internet Plans

Package Typical monthly cost
200Mbps (300Mbps in NYC DMA) / 200Mbps $40 (with AutoPay)
500Mbps (600Mbps in NYC DMA) / 500Mbps $60 (with AutoPay)
940Mbps / 880Mbps $80 (with AutoPay)

Without any cable infrastructure whatsoever, Verizon is much more dependent on fiber deployments, with max download speeds of 940Mbps available for 64% of its customers as of December 2019. Fiber is much better than cable at handling uploads, too, so Verizon Fios customers can expect high upload speeds that match their download speeds, or that come close. For instance, that top-tier 940Mbps plan comes with upload speeds of up to 880Mbps.

Outside of Fios fiber-optic service, the rest of the customer base gets its internet from Verizon via DSL, which the FCC lists as available to 87% of subscribers at much slower download speeds ranging from 1.1 to 10Mbps. Verizon also notes its growing 5G and LTE home internet service, which leverages the company’s cellular towers to beam internet connections directly into peoples’ homes.

“Our expansion of 5G Home, currently in 18 markets, will continue throughout the year,” a Verizon spokesperson tells CNET.

Verizon’s coverage is concentrated in the Northeast US, while Comcast Xfinity service is more decentralized, and available in several regions.



According to the FCC’s coverage maps, Verizon’s internet service is primarily located in the northeast US. Here’s a rundown of metro regions where the service is available:

  • Delaware
  • New Jersey
  • New York City
  • Albany, New York
  • Buffalo, New York
  • Long Island, New York
  • Plattsburgh, New York
  • Staten Island, New York
  • Syracuse, New York
  • Baltimore, Maryland
  • Salisbury, Maryland
  • Boston, Massachusetts
  • Harrisburg, Pennsylvania
  • Philadelphia, Pennsylvania
  • Pittsburgh, Pennsylvania
  • Providence, Rhode Island
  • Norfolk, Virginia
  • Richmond, Virginia
  • Washington, DC

Comcast offers Xfinity internet service in New England, as well, including in Boston, Hartford and parts of New York. With a total claim of 28.3 million residential customers, the sprawling service is also available in numerous other regions throughout the country, including Chicago, Atlanta and the Pacific Northwest.

All told, you’ll find Comcast Xfinity available in 40 different states, whereas internet from Verizon is available in nine states.

Pricing and plans

Both Verizon and Xfinity offer a variety of home internet plans, as well as bundles that package your home internet with other services like mobile or cable TV. You’ll find a greater variety of options with Xfinity, which offers twice as many plans as Verizon Fios.

The two providers are comparably priced at the high end, with gigabit or near-gigabit speed plans typically running for about $80 per month. Comcast also offers a Gigabit Pro plan that offers fiber-to-the-home speeds of 2Gbps, both download and upload — though it’s available in all Xfinity service areas, that plan requires a site inspection to confirm serviceability, and it costs $300 per month plus installation and fees. 

At the low end, both providers offer 200Mbps plans at about $40 per month, though Xfinity also offers speeds of 25 and 100Mbps for as low as $20 per month. Meanwhile, Verizon’s DSL service offers single-digit speeds for about $40 per month.

Beyond those baseline plans, both providers offer discounted rates for low-income households who qualify. With Verizon, the Fios Forward program lets qualified customers deduct $20 from the monthly cost of any Verizon Fios plan. That brings the cost of a 200Mbps fiber internet plan down to $20 per month, and the cost of a 940Mbps plan down to $60 per month.

With Comcast, low-income customers can sign up for the Internet Essentials plan, which offers speeds of 50Mbps for $10 per month. That’s the only low-income Xfinity plan Comcast offers, and it isn’t as fast as the multiple discount plans available from Verizon, but it is the least expensive option.

Per the 2020 ACSI Telecommunications Report, Verizon led all internet service providers with a customer satisfaction score of 73 out of 100. Comcast Xfinity came in at 66, which was 8% higher than the previous year — the biggest jump of any ISP rated.

American Customer Satisfaction Index

Customer satisfaction

Something else worth considering if you’re comparing Comcast Xfinity and Verizon Fios is how happy their existing customers are with their service. It’s a metric that the American Customer Satisfaction Index tracks with yearly surveys and reports, including a regular look at the top telecom providers.

In 2020, Verizon led all of the major internet service providers with a satisfaction score of 73 out of 100, eight points higher than the overall ISP satisfaction grade of 65. That makes two consecutive years at the top, and two consecutive years as the only ISP to rank in the 70s for customer satisfaction. 

Comcast finished with an above-average score, too, but at 66 out of 100, only just barely. Still, the report notes that Comcast’s 2020 score jumped 8% from 2019, which was the biggest gain of any ISP in that span. Meanwhile, Xfinity TV service saw its own category-leading jump, with an 11% swing from 2019 to 2020. Both are good signs that Comcast is moving in the right direction.
