Best Xfinity Internet Plan

Here are the best internet plans for different circumstances. For a much more in-depth article on what internet speed you need, click here.

#1 Best Overall – 300 Mbps – Fast/Performance Pro

Xfinity’s 300 Mbps plans are ideal for families between 3-6 people. This will be enough for all to simultaneously stream, game, and be in video calls. 

#2 Best for Single Household – 50 Mbps – Connect/Performance

If you are single, 50 Mbps will be enough. This will be enough for one high-quality stream, casual browsing, and other background processes simultaneously. 

#3 Best for a Couple – 100 Mbps – Connect Plus/Performance Pro

For two people, 100 Mbps is a good option. This will be enough for two high-quality streams, casual browsing, and other background processes simultaneously. 

That said, If both work from home, the upload speed might be a bit slow for high-quality video calls. 

#4 Best for Large Households – 600 Mbps – Superfast/Blast!

If you are a large household of 5+ members with many smart devices, 600 Mbps might be a better option. This will be enough for everyone in the house to watch 4K movies and any other background process.  

#5 Best for Extreme Users – 1200 Mbps – Gigabit Extra/Gigabit         

Most of the time, 1200 Mbps won’t be necessary. But if you are a small workplace or just want insanely fast downloads, it’s an option. 

This speed is more than enough for 10+ people to use the internet heavily simultaneously. Just make sure you have a router that can handle it. 

Also, the upload speed (35 Mbps) might be too low for many workplaces, so keep that in mind.

#6 Best for Large Business – 6000 Mbps – Gigabit Pro

6000 Mbps won’t be necessary for households or even many small businesses. Only get this if you are a larger business with heavy internet usage or a need for a high upload speed.

Xfinity Upload Speed

Since most of Xfinity’s internet plans are cable internet, the upload speed is often limited. Here you can see a table with what upload speed you get for what download speed.

Download SpeedUpload Speed
50 Mbps10 Mbps
100 Mbps10 Mbps
300 Mbps10 Mbps
600 Mbps20 Mbps
900 Mbps20 Mbps
1200 Mbps35 Mbps
6000 Mbps6000 Mbps

A Teams call needs between 2-4 Mbps [1]. This means that with the slowest plans, you can only have between 1-2 calls. While with the faster plans, you can have between 5-10. 

This is at least in theory. In practice, you will get limited to a bit less than that. Since your devices perform many background uploads automatically.

Unfortunately, if you want a faster upload speed, you will need to get the Gigabit Pro internet plan. Which costs $299.95/month and around $1000 in installation fee. 

But why does cable internet has such low upload speeds?

Historically, users haven’t needed much upload speeds, and huge uploads and video calls at this scale are new. 

This means that cable internet hasn’t had time to adjust the upload speed to the new demands. But with DOCSIS 3.1 and 4.0, this should start getting solved. 

For more info on Xfinity upload speed, click here.

Xfinity Data Caps

Comcast Xfinity has a standard data cap of 1,2 Terabit for their internet plans. To remove this, you will have to add $30 to your internet bill per month. [2]

You can also get it removed if you get the xFi Gateway Complete, and this will only set you back $25/month.

More info on Xfinity data caps here.  

But what is 1,2 Terabit enough for?

According to Xfinity, it will be enough for: a “video conference for 3,500 hours, watch 1,200 hours of distance learning videos, stream 500 hours of high-definition video content a month, or play more than 34,000 hours of online games.” [3]

After some research, I found this somewhat correct. It will be enough for 3,500 hours of video conferences, but not on high quality. And the same can be said for the 1,200 hours of distance learning videos. 

A better way to put it is that you will need to stream 4k for six hours per day the entire month to reach the data cap. [4]

This means that 1,2 Terabit will still be more than enough for most reading this. And if you are one of those for which it isn’t enough, you probably already know it. 

What happens if you go over the cap?

You need to pay $10 for every 50 GB of data, up to $100 each month. For perspective, 50 GB of data is enough for around 100 hours of standard-definition videos.

Both the data cap of 1,2 Terabit and the extra costs are about the same as what other providers with data caps have and charge. 

Nevertheless, not every ISP will have data caps. 

Xfinity Prices

Xfinity’s prices differ a lot in every state, so to check the most exact prices, go here

That said, there are a couple of things that always stay consistent. 

Xfinity Internet Price After 12 Months

Generally, the prices of an internet plan with Xfinity increases are 12 or 24 months. Depending on your deal and plan, this could be everything from a $15 addition to a $60 increase

Some plans even add another increase after 36 months. Some might cost more than double what you paid in the beginning. 

There are, however, ways to reduce your internet bill, which you can learn more about under how to lower costs. 

To learn more about Xfinity’s prices after 12 months, click here.

Xfinity Internet Hidden Fees

Here is a table of all of Xfinity’s hidden fees. 

FeeAmount
Professional installation$89.99
Self-installation $39.99
Reactivation fee$6.00
Late payment fee$10.00
Early cancelation feeVaries a lot, but costs more the earlier it is (a common rule is around $10 x the number of months left on the contract)
xFi Gateway$14.00/mo.
xFi Gateway Complete (pod and unlimited data usage included)$25/mo.
Xfinity FlexIncluded
Data overage fee$10 per 50 GB
No data caps$30/mo. extra

Xfinity Internet Equipment

When it comes to Xfinity’s internet equipment, you have three options. [5]

  1. xFi Gateway
  2. xFi Gateway Complete
  3. Bring your own
Wi-Fi optionMonthly feeDevice
xFi Gateway$14xFi Gateway (a modem/router combo device)
xFi Gateway Complete$25xFi Gateway, xFi Pod, unlimited data
Own equipment Free (except for buying them)Bring your own modem and router (either as one device or two)

With xFi Gateway, you get a modem/router combo device that will provide your home with Wi-Fi. And with xFi Gateway Complete, you get the Xfi Gateway and an extra “pod” that functions as a range extender. 

We here at Networks Hardware recommend you buy your own network devices. Because this is simply cheaper in the long run (learn more about renting vs. buying here).

That being said, Xfinity’s offers aren’t terrible, and you don’t have to consider what devices to get. 

Even though we do have articles to assist you in choosing your own devices. 

Also, if you are uncertain if you want a modem/router combo or separate devices, check out this article. (Spoiler, we think separate are better)

Xfinity Internet How to Lower Costs

The best ways to lower your Comcast Xfinity bill are 

  1. Get your own devices
  2. Lower your internet plan
  3. Cut unused TV channels
  4. Limit your data usage
  5. Negotiate a lower cost

Most of these are pretty straightforward and easy, but the last one is a bit more complex. 

It basically involves calling Xfinity and asking for their customer retention department. Then basically, say that you got a better offer from another ISP (most often AT&T) and ask what they can offer you. 

This allows the sales rep to offer you a deal that isn’t available to anyone else.

Xfinity TV

Xfinity TV service is pretty good, even if it’s nothing out of the ordinary. It has up to 265+ channels, the X1 DVR, high availability, and includes their Xfinity streaming app for free. 

However, the pricing gets a bit expensive considering the relatively low amount of channels, high hidden fees, and the no-contract deals. 

That being said, Xfinity TV is a good option if you want to bundle it with your internet and voice service. Because then you most likely will get away cheaper than most other options. 

Pros

  • Very available
  • Free Peacock Premium w/ X1 DVR
  • Xfinity Stream app for mobile viewing

Cons

  • Fewer channels than the competition
  • Long contract for the best price
  • High hidden fees

Xfinity Voice

If you have Xfinity Internet, you can also choose to get Xfinity voice service (VoIP). 

This is a landline phone service that doesn’t use the normal copper wiring but instated makes use of your internet connection. 

This results in cleaner audio and allows for features like three-way calling and voicemail-to-text messaging. [6]

Allowing you to have calls with thee parties at once and transform voicemails into text messages.

Xfinity Voice Pros & Cons

Here are some of the pros and cons of the Xfinity Voice service. 

Pros

  • 12 cloud-based features

Voice Equipment

If you get Xfinity Voice, you can either rent a modem/router combo with voice support from Xfinity for $14/month or get one yourself. 

As we already have said, we at Networks Hardware always recommend getting your own device. Because this is cheaper in the long run. 

Also, if you need help choosing a modem or a modem/router combo. Check out our article on the best voice modems

You will also have to get a handset phone, as this is not provided by Xfinity. This shouldn’t be any problem, because most commercial ones will work. 

Xfinity Voice Home Phone Features

Dependent on which plan you get, Xfinity Voice has up to 12 features:

  • Call forwarding
  • Caller ID with call waiting
  • Caller ID blocking per call
  • Caller ID

Xfinity Bundles

Xfinity Bundles are some of the best in the market, especially if you don’t need too many channels.

And even then, if you get their mid-tier plan, Digital Starter, it will only set you back $70/month. Lower than Spectrum, Cox, and AT&T start between $80-$90. To learn more, check out our Xfinity Bundle overview.

Here are some pros and cons of Xfinity’s bundles. 

Pros

  • Lots of options
  • Pretty good prices
  • High availability 
  • Xfinity Wi-Fi hotspots
  • Free Peacock Premium

Cons

  • Data caps
  • Long contracts

What Other Costs Do Xfinity Bundles Come With?

Like most other providers, Xfinity has a bad habit of adding fees for what feels like everything. Here are some of the fees you can expect with their bundles. 

  • Equipment – As discussed, if you rent a modem/router combo from Xfinity, they will charge you $14-25 extra per month. You will also need to get the X1 TV device if you get Xfinity TV. Which in itself costs an extra $7.50/month for every TV you want. 
  • HD technology fee – If you choose to use your own internet equipment and pass on the X1, Xfinity might charge you an extra 9.95/mo. for HD service.
  • Early termination fee – If you need or want to terminate your agreement before it ends, you will have to pay an early termination fee. This fee depends on your plan and how long you have left on your contract. 

Xfinity Deals

Xfinity’s deals change every couple of months, so for the most up-to-date look, go here

There are, however, some long-standing deals for customers. Below you can find them. 

Other Comcast Xfinity Deals

Here are some of the other Xfinity deals available. 

  1. Xfinity Flex with Peacock Premium – included in any Xfinity internet plan
  1. Xfinity with HBO Max, SHOWTIME, or Netflix – included in the high-tier bundles
  1. Xfinity Mobile discount – You can get a $400 discount per year if you add this to your current plan.

Xfinity Mobile

If you have Xfinity Internet, you are also eligible for Xfinity Mobile. 

This is a mobile service that uses the Verizon telephone infrastructure [7]. In my experience, the offers are pretty good compared to other mobile providers, especially if you decide to share the data between 3-4 people. 

Below you can see some of the plans you can choose between. 

PlanInclusion Price
1GB By the Gig Data Option1GB Data No Contract$15/mo
3GB By the Gig Data Option3GB DataNo Contract$30/mo
Unlimited Data OptionUnlimited Data No Contract$45/mo
10GB By the Gig Data Option10GB DataNo Contract$60/mo

Just note that the Unlimted Data option really isn’t unlimited. Because after 20 GB of usage in a month, your data speeds will be reduced to 1.5 Mbps download and 750 Kbps upload.

This is enough for low-quality streaming and web browsing, but not much more.

Xfinity Prepaid Internet

Xfinity Prepaid Internet is a pay-as-you-go option that offers you a slower internet connection for a flat rate and no-contract deal. 

This is a good option for you with sporadic internet needs that want to save some money. That said, it does offer fewer features than a normal Xfinity internet plan. 

For example, you won’t give you access to Xfinity’s Wi-Fi hotspot networks. Which is a network of millions of Wi-Fi networks which your mobile phone automatically connects to when in range. This will save you data on your mobile phone. 

Moreover, you need to buy Xfinity Prepaid’s $35 starter kit to get it. Which, as you guessed, cost $35. 

Also, the internet plans you have access to with Xfinity prepaid are between 50-100 Mbps. This will only be enough for 1-3 people.

For more info check out our article on Xfinity Prepaid Internet.

Xfinity Home Security

Xfinity Home Security is a home security solution that combines your Xfinity internet with a security system.

It has features such as camera systems, security zones, and keypad locks. 

Overall, Xfinity home security might be a good idea if you bundle it with many other Xfinity services. But otherwise, we generally think there are better options out there. 

For more info, read out Xfinity Home Security Review.

Xfinity Availability 

Xfinity is one of the largest providers in the US and is available in 40 states. 

However, just because it is available in a state where you live does not mean that it’s 100% sure to be available at your location.

Xfinity Customer Service

To reach Xfinity’s customer service, call: (800) 934-6489.

One thing, though, before you call, make sure you have your address, account number, and phone number connected with the account ready at hand. 

The support is open between 7 a.m.-9 p.m. Monday — Saturday. 

How good is the Xfinity Support?

A couple of years ago, Xfinity got a lot of flack for having terrible support. And that was the case. 

Since then, however, they have improved rapidly and are now considered acceptable too good. Depending on who you ask. 

In our experience, the Xfinity support has been helpful and easy to get a hold of. But it will depend on who is on the other side.

Xfinity Essentials

Comcast Xfinity Essentials is an internet program for low-income families, seniors, veterans, and college students. 

It offers a 10 Mbps internet speed, a free gateway, the option to buy a low-cost computer ($150), and access to a learning center. 

Am I Eligible for Xfinity Essentials? 

The best way to check is to go to the FCC application page

There you will answer a couple of questions and provide your information. 

Xfinity vs. the Competition

Xfinity generally stacks up pretty well versus the competition. But sometimes, you might want to pick another internet provider.

Xfinity vs. AT&T

If you have to decide between Xfinity and AT&T, you need to look at what AT&T offers. If they provide you fiber optic internet for a price very similar to Xfinity – get AT&T. 

The reason is that fiber internet will provide you with the same upload as download speeds. Contrary to Xfinity’s cable internet, which will have way lower upload speeds than download speeds. 

Also, fiber internet won’t be slower during peak hours, while cable internet nearly always is. 

That said, if you plan to bundle your TV, internet, and mobile phone, Xfinity will most often be a better option because of the bundle deals they offer.

Moreover, don’t ever get AT&T DSL if you have access to Xfinity’s cable internet. Because cable internet is better than DSL in basically every way. 

Xfinity vs. Verizon

If you have the option to get Verizon fiber internet for a similar price to Xfinity’s cable internet –  get the fiber optic internet from Verizon. 

This is because, as previously said, fiber internet will have way better upload speeds than cable internet. 

As well as a more consistent speed that won’t be slower during peak hours which is the case for cable internet. 

However, suppose you have access to Xfinity’s fiber internet and need extreme speeds. In that case, Xfinity’s 6000 Mbps plan is the way to go. Even if few people will need this. 

Suppose you only have access to Verizon’s DSL internet and Xfinity’s cable internet, then always go with Xfinity’s cable internet. 

Cable internet is superior to DSL in most ways. Providing faster, more reliable internet for a better price. 

Bottom Line

This overview strives to cover the most important aspect you need to know before getting Xfinity internet, TV, or voice. 

But as things change quickly, we recommend you check out the offers and information on Xfinity to see what offers you have where you live.
