Att Fiber Price: Plans, Monthly Cost & Fees

AT&T Fiber is a fiber-optic home internet service sold in cities and suburbs where AT&T has built out its network. Unlike cable, fiber plans are usually sold with matching download and upload speeds, and AT&T lists tiers by speed, from 300 Mbps up to multi-gig options.

The prices on this page come from third-party roundups and from AT&T's own fiber page, and AT&T does not publish one fixed national price list. What you are offered depends on your address, which tiers are available there, and whether you add an eligible AT&T wireless plan. Treat the numbers as a guide, then check your address on att.com before deciding. The roundup figures were checked on Oct 14, 2026.

The tiers below are named for their speeds. The prices reflect what these sources reported for new customers, and they can change.

The 500 Mbps tier was reported at $60/mo by MyUtilitySearch, and the 1 Gig tier at $70/mo by Allconnect. Those two sources agree on the middle of the range, but you may see different figures on AT&T's site depending on where you live. Some tiers, including the entry 300 Mbps plan and the fastest multi-gig plan, may not be offered at every address.

AT&T advertises lower fiber prices when you also buy an eligible wireless plan. These bundle figures are the reason you may see a starting price well below the plan prices above.

According to the roundup, internet starts at $35/mo with a qualifying bundle, and the bundle can save $15/mo or more on internet service. AT&T's own fiber page advertises plans from $35/mo. That headline starting price generally assumes conditions such as a wireless bundle, so read the fine print for the offer that applies to you.

Several factors move the monthly amount.

• Speed tier. Faster plans cost more, but the jump between tiers is not always proportional.
• Address. Fiber is not built everywhere, and the tiers offered can differ between neighborhoods.
• Bundling. Adding qualifying AT&T wireless service can lower the internet price.
• Autopay and paperless billing. Advertised prices often assume these discounts.
• Promotions. Offers for new customers can change what you pay for a period, so ask what the price is after any promotion ends.

The monthly plan price is not always the full bill. Taxes and fees apply on top of advertised prices. Ask whether equipment is included, whether any installation or activation charge applies, and whether there is a contract term. The sources reviewed describe the plans as contract free with included equipment, but terms can differ by offer, so confirm them before you order.

Fiber suits households that upload large files, join frequent video calls, or have many connected devices. A smaller household that mostly browses and streams may do fine on a lower tier. Since tier names are tied to speed rather than a verdict on quality, compare the speeds against how your household actually uses the connection, and compare against other providers available at your address.

Enter your address on AT&T's fiber page to see the tiers available and the price for each. Ask whether the displayed price includes autopay and bundle discounts, and request a written summary of fees. If you are comparing providers, note the price after any promotional period, not only the first bill.
