If you go by price per month, the cheapest AT&T internet plan is its Fiber Internet 300 plan, which rings in at $55 a month for your first year. But if you can get only AT&T DSL internet, your cheapest option is the AT&T Internet Air plan. (And if you go by price per Mbps, the AT&T Internet 1,000 plan offers the best value.)

Let’s grab our calculators and dig into the details to see why these three AT&T internet plans stand out when it comes to price.

The AT&T Internet Air plan costs the same as AT&T Fiber 300, but it comes with less download speeds. If you have the choice of Internet Air or Internet 300, go with Internet 300 for sure.

If you're unsure which plans are available to you, the best way to find out if you can get this plan is to enter your address on the AT&T site—or try out our easy zip checker tool.

Cheapest AT&T Fiber internet plan

The AT&T Internet 300 plan is the cheapest fiber plan available, but all three AT&T Fiber plans are cheap compared to other similar providers.

By comparison, here’s how much you’d spend for a similar download speed from Cox or Spectrum:

† Price after $5/mo Autopay & Paperless bill discount (w/in 2 bills). Plus taxes & fees. Monthly State Cost Recovery Charge in TX, OH, NV applies. Ltd. availability/areas.

As you can see, it’s pretty difficult to compete with AT&T Fiber’s promotional prices. So rest assured these internet plans are a good deal. The only thing is you’ll need to live in a city where AT&T Fiber internet service is available.

Don’t forget to check local provider prices

Your town or city may also have a local internet provider that offers a better deal than even AT&T. It never hurts to check with your local electric co-op or Google to see if you come up with a cheaper internet option.

Cheapest AT&T internet plan by price per Mbps

AT&T Wi-Fi internet plans are priced pretty competitively, but what about the price for the speed you get? Is it good?

Turns out it’s a good price for the speed you get—for the most part. Let’s take a look at each of AT&T’s internet plans and the price per Mbps for each one:

AT&T internet price per Mbps

Plan	Monthly price	Download speed	Price per Mbps	Details
AT&T Fixed Wireless	$59.99/mo.°	25 Mbps	$2.39/Mbps	View Plan
AT&T Internet Air	$55/mo.	140 Mbps	$0.39/Mbps	View Plan
AT&T Internet 300	$55/mo.*	300 Mbps	$0.18/Mbps	View Plan
AT&T Internet 500	$65/mo.*	500 Mbps	$0.13/Mbps	View Plan
AT&T Internet 1000	$80/mo.†	1000 Mbps	$0.08/Mbps	View Plan
AT&T Internet 2000	$110/mo.†	Up to 2000 Mbps	$0.05/Mbps	View Plans
AT&T Internet 5000	$180/mo.†	Up to 5000 Mbps	$0.36/Mbps	View Plans

° Plus taxes when bundled w/ qualifying AT&T wireless svc. Incl 350GB data/mo., overage chrgs apply. Ltd. avail/areas in U.S.

† Price after $5/mo Autopay & Paperless bill discount (w/in 2 bills). Plus taxes & fees. Monthly State Cost Recovery Charge in TX, OH, NV applies. Ltd. availability/areas.

Speeds based on wired connection. Actual speeds may vary. For more info, go to www.att.com/speed101.

The AT&T Internet 1,000 plan gets you the most bang for your buck with the lowest price per Mbps of them all. This is similar to what we found with the Xfinity Gigabit plan’s price per Mbps, so we’re not surprised.

Do you need 1,000 Mbps speeds?

Just because the AT&T Internet 1,000 plan has the best price per Mbps doesn’t necessarily make it the best deal for you. Check out our internet speed guide to get a peg on what download speeds work best for you so you don’t overspend on unnecessary Mbps.

In fact, all of the AT&T Fiber plans have a decent price per Mbps. The AT&T Internet 300 plan is okay as well at 18 cents per Mbps, but the Fixed Wireless plan’s price per Mbps gives us the heebie-jeebies.

Counting on 40 cents per Mbps for Internet Air is correct only if you can get the max speed of 140 Mbps. If speeds in your area are slower than 140 Mbps, your value goes down. (This is another instance where we’d recommend looking to see if there’s a local ISP or another rural internet provider with a better price.)
