Now that many internet providers are ramping up speeds to remain competitive, streamers, gamers, and cord cutters have a lot more options to choose from. In the past, 1 Gbps or 1,000 Mbps plans (also known as ‘Gigabit’ plans) were rare and expensive. Now, they are becoming more commonplace and affordable.

So, how can we determine the best Gigabit internet plans on the market in 2021? First, we will look at the following criteria:

  • Actual plan speeds (as opposed to advertised plan speeds)
  • Standard Pricing (as opposed to promotional pricing)
  • Network size and coverage areas (whether or not the plan is available in your location)

These are the three most important factors when choosing between internet providers. Additional factors like ‘freebies,’ no-contract plan flexibility, and data caps will also be considered. However, these features are usually customizable with most major internet providers.

Who has the best gigabit internet plan? Our Pick: CenturyLink Fiber Gigabit

At first glance, the CenturyLink Fiber Gigabit plan may not deliver the fastest speeds, but our research and testing have found that CenturyLink offers the best gigabit plan overall. The first thing that caught our eye is CenturyLink’s transparent pricing and how much cheaper it is than other fiber providers. Sure, AT&T has the cheapest monthly rate ($60 a month), but that advantage disappears when you include their equipment fee and price hike after the first year.

CenturyLink’s fiber internet is available in select cities across the country, reaching approximately 21 million people. This makes CenturyLink the 4th largest provider of residential fiber internet in the country. However, one downside is that actual plan speeds vary widely depending on where you live. It’s normal for actual speeds to be lower than advertised speeds, so expect to see about 80-90 percent of the speeds CenturyLink advertises.

That said, the CenturyLink Fiber Gigabit plan also comes with some additional perks. First, this plan features no contracts, no Early Termination Fees (ETFs), and no data caps. You also get free installation and a free wireless modem.

Let’s take a closer look at the top five Gigabit internet plans to see how they stack up:

Provider + Plan Connection Type Download/Upload Speed Promotional Price Standard Price
AT&T Internet 1000 Fiber 1000 Mbps / 1000 Mbps $60 per month (one year) Not listed
CenturyLink Fiber Gigabit Fiber 940 Mbps / 940 Mbps N/A $65 per month
Verizon Fios Gigabit Connection Fiber 940 Mbps / 880 Mbps N/A $79.99 per month
Frontier Gig Service Fiber 940 Mbps / 880 Mbps $79.99 per month (one year) $89.99 per month
Cox Internet Gigablast Cable 940 Mbps / 35 Mbps $99.99 per month (one year) $119.99 per month

There are some major differences in pricing and even speed among the top five Gigabit providers. However, the table above does not tell the whole story. So, let’s see how all five plans compare when it comes to actual speed, price, and network size:

Gigabit speed test comparison

According to BroadbandNow, here’s how the top five Gigabit internet-only providers compare when it comes to average download speeds nationwide. Keep in mind that these are overall averages, not just gigabit plan averages.

  1. Verizon Fios: 453.12 Mbps
  2. AT&T Internet: 352.39 Mbps
  3. Cox Internet: 287.50 Mbps
  4. CenturyLink: 104.38 Mbps
  5. Frontier: 91.26 Mbps

Clearly, Verizon Fios provides the best average download speeds across its network. But while this is valuable information, it isn’t the whole story. These numbers cover all of the plans each provider offers, not just the Gigabit plans. We’ve found that the CenturyLink Fiber Gigabit plan offers respectable speeds of up to 80-90% of what’s advertised, which would amount to around eight or nine times the average CenturyLink speed listed here! While CenturyLink may not be delivering high speeds to all of its customers, it is treating gigabit customers in most cities well.

Gigabit price comparison

Now that we’ve seen who performs best with speeds, let’s take a look at prices. It’s important to note that we will only work with the information that is available as of November 2020. Prices are liable to change in the coming months. Additionally, some providers do not provide information regarding their standard pricing. In any case, here are the top five Gigabit plans ranked by their standard price:

  1. CenturyLink Fiber Gigabit: $65 per month
  2. Verizon Fios Gigabit Connection: $79.99 per month
  3. Frontier Gig Service: $89.99 per month
  4. Cox Internet Gigablast: $119.99 per month
  5. *AT&T Internet 1000: Not Listed

While it would appear in the table above that AT&T provides the cheapest Gigabit plan, it’s important to note that this is just the promotional rate for the first year of service. Since AT&T does not advertise its standard rate, it’s difficult to say with certainty how much you would pay after the first year of service. So, while AT&T does technically offer the cheapest prices from the start, CenturyLink offers the cheapest monthly premiums for the long-term at just $65 per month.

Gigabit network area comparison

Finally, we will look at how the five Gigabit providers compare based on the total number of states in which they offer their services:

  1. CenturyLink Fiber Gigabit: 49 states + District of Columbia
  2. AT&T Internet 1000: 21 states
  3. Cox Internet Gigablast: 18 states + District of Columbia
  4. Verizon Fios Gigabit Connection: Nine states + District of Columbia
  5. Frontier Gig Service: Seven states

While CenturyLink provides coverage across the nation, AT&T is technically the largest provider of residential fiber internet. This is due to its concentration in densely-populated cities throughout the south and midwest. In fact, AT&T’s fiber network reaches approximately 36 million people, while CenturyLink reaches about 21 million people.

Additional features

Now that we’ve covered the most important factors, it’s time to consider additional features and perks of each service:

  1. Verizon Fios Gigabit Connection: No contracts, no ETFs, free modem/router, free installation, no data caps, Amazon Echo Show 5, Ring Stick Up Cam Battery, TV bundling options
  2. CenturyLink Fiber Gigabit: No contracts, no ETFs, free modem/router, free installation, no data caps
  3. AT&T Internet 1000: No contracts, no ETFs, no data caps, $100 promotional gift card, TV bundling options
  4. Frontier Gig Service: No contracts, no ETFs, free modem/router, no data caps
  5. Cox Internet Gigablast: Phone and TV bundling options

As you can see, Verizon offers the most incentives to choose their Gigabit plan. That said, CenturyLink and AT&T both offer similarly enticing offers. This ranking is somewhat subjective, as I think CenturyLink’s free installation and free modem/router are better offers than AT&T’s gift card and TV bundling options. However, you may think differently if you’re looking to bundle plans together. In any case, it’s easy to see that Frontier and Cox offer far fewer perks than any of their competitors.

Total rankings

Now that we’ve crunched all the numbers, it’s time to see why CenturyLink offers the best all-around Gigabit plan. To keep things simple, we’ve given a score out of 100 for each ranking:

  • 1st = 100
  • 2nd = 80
  • 3rd = 60
  • 4th = 40
  • 5th = 20

Additionally, each category has a weighted score as follows:

  • Speed = 30%
  • Price = 30%
  • Network Area = 30%
  • Additional Features = 10%

So, let’s see how the top five Gigabit providers compare based on their final scores:

  • CenturyLink Fiber Gigabit: 4th in speed, 1st in price, 1st in network area, 2nd in additional features (Weighted Score = 80)
  • Verizon Fios Gigabit Connection: 1st in speed, 2nd in price, 4th in network area, 1st in additional features (Weighted Score = 76)
  • AT&T Internet 1000: 2nd in speed, 5th in price, 2nd in network area, 3rd in additional features (Weighted Score = 60)
  • Cox Internet Gigablast: 3rd in speed, 4th in price, 3rd in network area, 5th in additional features (Weighted Score = 50)
  • Frontier Gig Service: 5th in speed, 3rd in price, 5th in network area, 4th in additional features (Weighted Score = 34)

Is gigabit internet worth it?

Whether or not you should go with a Gigabit plan will depend on your specific needs. That said, none of the plans on the market deliver average speeds that come close to what is advertised. So, if you want to get the most bang for your buck, you might need to go with a lower speed fiber plan.

However, this will also depend on the provider and the individual plan. For example, the next step down in CenturyLink fiber plans is the Fiber 100, which advertises download speeds up to 100 Mbps at $49 per month. This plan has a monthly data cap of 1 GB and does not come with a free modem/router like the CenturyLink Gigabit plan.

The router rental fee for this plan is $10 per month and you’ll have to pay overage fees if you go beyond your monthly data cap. Therefore, you might be better off just paying the additional $16 per month for the Gigabit plan. In any case, you’ll have to weigh the pros and cons of each plan and provider before making a decision.

How to get gigabit internet

If you’d like to upgrade to a Gigabit internet plan, you can simply contact your current internet provider to see if they offer something comparable. In the event that your provider does not have a Gigabit plan, you can learn more about switching to the plans outlined above at the following links:

It’s important to note that all but one of these plans operate on a fiber network. While you may be able to use a cable modem or router that you already own with Cox Internet Gigablast, all of the other plans will require you to use modems designed for fiber-optic internet. So, if you’d like to make the change to a Gigabit plan, you’ll likely need to have a professional install your new internet setup.
