Plans and pricing: Google Fiber vs. Xfinity

Xfinity offers a much wider range of plan options than Google Fiber, which offers only two. If you’re looking for higher speeds, however, Google Fiber offers more speed for the monthly cost.


Google Fiber plans and pricing

Google Fiber 1 Gig$70.00/mo.1 Gbps (1,000 Mbps)
Google Fiber 2 Gig$100.00/mo.2 Gbps (2,000 Mbps)

Google Fiber offers incredibly fast speeds for a very reasonable price. Despite its limited availability, Google Fiber has had a huge impact nationwide, popularizing fiber home internet and pushing other ISPs to improve their services to keep up.1 It has only two options for plans, but both have straightforward pricing and offer a great value. The 2 Gbps plan isn’t available in all Google Fiber locations, but like the 1 Gbps plan, its availability is slowly expanding.

Xfinity offers a wide variety of plans. Not every plan is available in every location, but most locations offer a range of plans from basic but affordable to fairly robust. While Xfinity’s plans do reach into the higher speeds, these tend to be more expensive than similar plans offered by Google Fiber.

Xfinity’s biggest advantage is its wide availability. Xfinity is one of the largest ISPs in the US, and because its entire network is based on cable connections, it can offer higher speeds and more reliable connections than ISPs that operate DSL networks.

Xfinity has some fiber-to-the-home options similar to Google Fiber, but Xfinity has barely dipped its toes into the world of fiber. While Xfinity boasts one of the largest cable networks in the US, it’s fiber footprint is less than 1% of that of Google Fiber’s, which means it’ss incredibly small, even compared to Google Fiber’s already limited availability.

Following Google Fiber’s introduction of its 2 Gigabit internet plan, Xfinity upped its max advertised download speed with the introduction of its Gigabit X3 plan, which has a max speed of 3,000 Mbps (3 Gbps) and once again placed the cable giant’s fiber plan in first place when it comes to speed. The catch is the plan has limited availability: you can get it only if you live in the Central region of Xfinity’s nationwide network. While we’re always excited when providers push to offer better speeds to their customers for the same price, it’s not yet clear if this is a sign that Xfinity is moving to invest in its fiber network in the same way that Google Fiber is.

In any case, Xfinity’s 2 Gbps fiber plan is also three times the price of Google Fiber’s 2 Gbps fiber plan, so even if you’re one of the few people who has access to Xfinity’s fiber network, we suggest going with a less expensive option.

Extra fees: Google Fiber vs. Xfinity

 Equipment FeeInstallation FeeOther Fees
Google FiberFreeFreeNone
XfinityUp to $15.00/mo.Up to $125.00
(Free for self-installation with standard shipping)
$10.00 late payment fee
$10.00/50 GB overage fee
$30.00/mo. for unlimited data

While Xfinity offers many plans priced lower than Google Fiber’s, it does have equipment fees and upfront installation costs that cut into your savings. If you’re going with an Xfinity plan to save some money on your monthly bill, make sure you take fees into account so you don’t end up paying more for less. You can also purchase your own router to save on equipment rental fees.

Google Fiber doesn’t have any fees beyond your normal monthly bill, including late fees. The ISP gives you a free router and free installation when you sign up. If your outstanding balance is unpaid for more than 40 days, your account will be suspended.3 Fortunately, there are no additional fees to reinstate a suspended account, either. You just have to pay your remaining balance in full.

Internet types: Google Fiber vs. Xfinity

 Internet typeDetails
Google FiberFiber
XfinityCable, FiberView Plans

Google Fiber operates an all-fiber network, so you’re always going to get the same high speeds and reliable connection, no matter where you are.

Xfinity’s network mostly delivers cable internet, which gives you good download speeds with slower upload speeds. Xfinity also offers fiber connections for it’s 2,000 Mbps plan that’s available in some locations, but the availability is extremely limited.

Data caps: Google Fiber vs. Xfinity

 Data capDetails
Google FiberNone
Xfinity1.2 TB–UnlimitedView Plans

Google Fiber doesn’t have any data caps, which means you can use it as much as you need without worrying about throttled speeds or overage fees.

Xfinity cable plans have a data cap of 1.2 TB (1,200 GB) in most of its coverage areas except the Northeast region, where data caps have been delayed until 2022.2 This might seem like a lot of data to go through in a month, but a terabyte of data can go by surprisingly fast if you stream video on a regular basis.

If 1.2 TB isn’t enough monthly data for you, you can get unlimited data for an additional monthly fee of $30. Those who sign up for Xfinity’s rare Gigabit Pro fiber plan get unlimited data included, just like Google Fiber customers.


Contracts: Google Fiber vs. Xfinity

 Contract lengthDetails
Google FiberNo contract
XfinityUp to 2 yrs.View Plans

Google Fiber doesn’t require a contract, so you simply pay on a month-to-month basis. Most Xfinity plans require a 12- or 24-month contract; however, it does offer no-contract internet plans as well if you don’t want to be locked in with one provider or think you might move soon.

Installation: Google Fiber vs. Xfinity

 Installation optionsDetails
Google FiberFree professional installation
Xfinity$39.99 professional installation
Free for self-installation with standard shipping
View Plans

Google Fiber offers free professional installation to new customers, and its technicians do an amazing job, keeping all the cables neat and tidy.

Xfinity offers professional installation for $39.99, which is still a very low price. If you don’t want to pay even that much, Xfinity offers a free self-installation option as well, which it makes easy with an app that gives you step-by-step instructions.

Availability: Google Fiber vs. Xfinity

When it comes to availability, few ISPs can match Xfinity, which has a network that runs from coast to coast and covers over a third of the US population.4 Its reach doesn’t extend very far into rural areas, but if you live near a big city and have cable hookups at your house, there’s a good chance you have access to Xfinity internet.

Availability is the main weakness of Google Fiber. Its network is available in only a few Google Fiber cities, bringing access to less than 1% of the US population.4 Although its network is expanding, Google Fiber is still a relatively small ISP and faces an uphill battle when it comes to increasing its coverage.

Final call: Google Fiber vs. Xfinity

If you have access to both Google Fiber and Xfinity in your area, we recommend going with Google Fiber to get the most speed and reliability for the cost. Those with very basic internet needs might save some money by going with a cheaper Xfinity plan, but be aware of extra fees and potential contracts so you don’t end up paying more for less.
