Xfinity internet deals and plans (October 2026)
Xfinity reworked its plans around a 5-year price guarantee with equipment and unlimited data included. Here's what each plan costs and what to watch for.
Xfinity's 5-year price guarantee plans are 300 Mbps for $45/mo, 500 Mbps $60, 1 Gig $70 and 2 Gig $100, with WiFi equipment and unlimited data included and no contract. Prices assume AutoPay and paperless billing. On a budget, NOW Internet is $30 for 100 Mbps.
Xfinity plans with the 5-year price guarantee
What the deals include
- Equipment: the WiFi gateway is included on these plans, so there's no monthly rental.
- Unlimited data: included. Older Xfinity plans keep the 1.2 TB monthly cap.
- Mobile: one Xfinity Mobile Unlimited line free for a year on 300 Mbps and faster.
- Streaming: 1 Gig includes Peacock Premium for two years.
- Reward offers: some plans carry a prepaid card of up to $200; see internet gift card offers.
5-year guarantee or 1-year plan?
Xfinity also sells 1-year plans that cost less in the first year but rise afterward. If you expect to stay more than a year, the 5-year guarantee usually costs less in total. After five years, the price moves to Xfinity's standard rate, which reports put about $30/mo higher. See the 2026 Price Lock Index.
Cheaper Xfinity options
- NOW Internet: $30/mo for 100 Mbps with taxes, fees and equipment included, prepaid.
- Internet Essentials: $14.95/mo for 75 Mbps or $29.95 for 100 Mbps for qualifying low-income households. See low-income internet programs.
How Xfinity compares
Against fiber, Xfinity's uploads are slower (100 Mbps on most plans). Where fiber reaches you, AT&T Fiber 300 is $50 with symmetrical speeds. Against 5G home internet, Xfinity is faster and steadier but costs a little more. Read our Xfinity review.
How to get the advertised price
- Enroll in AutoPay and paperless billing; the listed prices include a $10/mo discount for both.
- Choose a 5-year price guarantee plan rather than a 1-year plan if you'll stay longer than a year.
- Order online and check whether a prepaid card or free mobile line applies to your address.
- Confirm the price, the guarantee length and what's included in your order confirmation.
What happens after five years
When the guarantee ends, the plan moves to Xfinity's standard rate. Reports put that about $30/mo higher. Set a reminder a month before, then ask for a current plan or compare other providers.
Already an Xfinity customer?
The advertised deals are for new customers, but you can ask to move to a current plan. Some long-time customers report getting the 5-year price guarantee that way. It's worth asking if you're on an older plan: those can still carry the 1.2 TB data cap and a $15/mo gateway fee, and current plans include unlimited data and the gateway. Ask what price and guarantee you'd get before you agree, and ask for the retention team if the first offer isn't better. Our guide to the Xfinity price increase covers why bills rise and what to say, and negotiating an internet price increase works for any provider.
