The short version
Xfinity, Comcast’s consumer brand, sells cable internet with an unusual promise: a five-year price guarantee on its 300 Mbps, 500 Mbps and 1 Gig plans, with no annual contract and no early termination fee. The 300 Mbps tier is $45 per month and 1 Gig is $60, both with Wi-Fi equipment included and unlimited data.
The conditions matter. Every advertised price requires AutoPay from a stored bank account plus paperless billing, taxes and fees are extra, and Xfinity does not publish upload speeds, installation fees or what the price becomes after year five. Satisfaction results are middling: 71 in the 2026 ACSI study for Xfinity’s non-fiber service. Prices verified October 30, 2026; providers change promotions frequently — confirm at checkout.
Plans and pricing (as of October 30, 2026)
Xfinity’s national plans page lists three tiers under a 5-Year Price Guarantee, which locks the base monthly internet rate for 60 months.
- Entry tier: 300 Mbps (5-Year Price Guarantee) — 300 Mbps download, upload speed not disclosed, $45 per month for 60 months.
- Middle tier: 500 Mbps for $50 per month.
- Top tier: 1 Gig (5-Year Price Guarantee) — 1,000 Mbps download, upload speed not disclosed, $60 per month. This is the fastest plan shown nationally; faster multi-gig tiers may exist in some markets, but we could not verify them.
There is also a shorter alternative for new customers: 300 Mbps for $40 per month for one year, labeled “Offer ends 12/1.” That saves $5 a month for 12 months but gives up the five-year lock.
The post-guarantee price is not stated on the plans page, so we could not verify what you will pay in year six. A 60-month lock is long enough that this matters less than it does with 12-month promos, but it is still an open question.
Fees and fine print
- Contract: None. Xfinity’s FAQ states there is no annual contract or early termination fee.
- Early termination fee: None.
- Equipment: Included. Plans “include WiFi equipment,” per the official page.
- Installation: Not disclosed. The page mentions same-day setup but no fee, so we could not verify the install cost.
- Data cap: None. All current plans advertise unlimited data, and no 1.2 TB cap is referenced on the current page.
- AutoPay and paperless: This is the big one. All pricing requires AutoPay with a stored bank account (not a credit card) and paperless billing. If you prefer paying by card or receiving paper statements, expect a different price.
Speed and reliability
Xfinity delivers service over a hybrid fiber-coax cable network. Cable download speeds are competitive with fiber at these tiers, but upload speeds on cable are typically much lower than download, and Xfinity does not publish them on its plans page. If upload matters to you, ask for the specific figure for your address before ordering.
ACSI tracks a separate “Xfinity Fiber” segment, though we could not verify where that product is sold. In the 2026 ACSI study, Xfinity’s non-fiber service scored 71, up from 69, and Xfinity Fiber scored 77, up from 75.
In the J.D. Power 2026 U.S. Residential ISP Satisfaction Study, Xfinity scored 558 in the North Central region, slightly above the segment average of 553, but it was not a regional winner.
Where it’s available
A CNET analysis syndicated on AOL puts Xfinity in 39 states with about 35% nationwide coverage, one of the broader wired footprints in our comparison. Cable availability is still address-specific, so check eligibility before planning around these prices.
