Detroit is a Tier A metro that prices like Tier B in a lot of buildings. Downtown and Corktown are competitive. AT&T fiber, Comcast, Rocket Fiber, and now Ezee Fiber all chase the same commercial blocks. Step outside the core, into Eastern Market warehouses, older New Center office stock, or the inner-ring suburbs, and your real choices narrow fast. The other thing to know: Michigan's statewide video franchise rules mean local governments have less negotiating pressure on cable carriers than you see in other states. That changes nothing about your bill directly. It does explain why Comcast pricing in Detroit looks like Comcast pricing in Cleveland.
The Detroit metro has more carrier choice than most people assume. Comcast Business has the dominant cable footprint. AT&T Business Fiber covers a growing share of commercial blocks downtown and in the inner suburbs. WOW! Business is on most blocks in the western suburbs and parts of Detroit proper. Rocket Fiber has a niche presence downtown. T-Mobile fixed wireless is widely available.
The pricing problem in Detroit is the same one that hits most upper midwest metros. Many businesses signed long-term Comcast or AT&T contracts during the 2020 to 2022 period and have never tested the new fiber options that arrived since.
What's grounded in Detroit
Detroit's commercial activity sits in three places. Corktown, west of downtown, is one of the metro's fastest-growing commercial districts, anchored by Ford's Michigan Central campus rebuild. Eastern Market, northeast of downtown, holds the metro's largest mixed-use food, wholesale, and small-business corridor. New Center, north of downtown around West Grand Boulevard, concentrates mid-size office and healthcare tenancy. Rocket Companies, headquartered downtown, and Henry Ford Health are two of the largest commercial accounts in the metro and drive heavy enterprise telecom demand.
In February 2026, Ezee Fiber said it would begin Metro Detroit FTTP construction and offer dedicated business service up to 100 Gbps as it entered the Michigan market. That puts a real new fiber overbuilder against AT&T and Comcast in this metro for the first time in years. One regulatory wrinkle: Michigan's Uniform Video Services Local Franchise Act uses a uniform statewide video franchise agreement administered by the Michigan Public Service Commission, which means city-level franchise renewal leverage does not exist the way it does in some states.
What you should be paying
These are dedicated internet ranges from current carrier wholesale data, marked up to typical retail.
Detroit dedicated internet, typical retail (mid 50%)
Monthly recurring charge, dedicated internet access (DIA). Numbers are derived from current carrier wholesale quotes. Shown as a metro-tier band where city-level data is thin.
| Speed | Typical retail (mid 50%) | Sample size |
|---|---|---|
| 100 Mbps | $630 – $800/mo | n = 7 |
| 500 Mbps | $840 – $1,160/mo | n = 5 |
| 1 Gbps | $1,050 – $1,455/mo | n = 6 |
| 10 Gbps | $1,330 – $2,660/mo | n = 7 |
If your bill sits above the high end of the band, you are likely overpaying.
Analyze My Bill FreeFor Comcast Business coax at 600 Mbps, the fair price is $150 to $230 a month for a single office. For AT&T Business Fiber at 1 Gbps, expect $180 to $260 a month.
Carriers worth quoting in Detroit
Five carriers cover most addresses in the metro.
- Comcast Business. Coax everywhere, fiber in select buildings.

- WOW! Business. Strong in the western suburbs and parts of Detroit proper.
- Rocket Fiber. Niche but real fiber coverage downtown.
- T-Mobile Business Internet. $85 a month for 200 to 300 Mbps. Useful benchmark.
If you have not had three of these on a quote sheet, you have not run a real comparison.

Carriers worth a quote here
- Comcast Business
Dominant cable footprint across the city and suburbs, on almost every commercial block. Pricing is process-driven and rarely flexible without a competing fiber quote in hand.
- AT&T Business
Fiber presence is strongest downtown, Corktown, New Center, and the inner suburbs along Woodward. Off-net buildings still get copper-era pricing, so confirm on-net status before assuming a fiber quote is competitive.
- Astound Business
WOW! is now part of Astound and covers most of the western suburbs plus parts of Detroit proper. Often the cheapest broadband option on a block when it's available, and useful as a price check against Comcast.
- Everstream
Regional fiber overbuilder with a real Detroit presence, especially around industrial and healthcare corridors. More negotiable than the nationals and worth quoting on any DIA or wave requirement above 1 Gbps.
- Lumen Business
Long-haul and enterprise DIA in select downtown and New Center buildings. Currently hungry for business and more flexible on price than they were two years ago, but on-net building count is limited.
- Crown Castle Fiber
Strong in metro fiber routes and on-net in a handful of downtown and Midtown buildings. Best fit for multi-site customers who need dark fiber or wavelength services rather than retail DIA.
- T-Mobile Business
Fixed wireless is broadly available across the metro and works well as a low-cost failover. Speeds and latency vary by tower, so test before relying on it for anything voice or transaction-critical.

Detroit, Michigan market notes
Common questions about business internet in Detroit, Michigan
Is Rocket Fiber actually an option for my business?
Only if you're in their downtown Detroit footprint, which is small and concentrated around the central business district and parts of Midtown. They build to specific buildings rather than entire neighborhoods. Call them with your exact address before assuming they're on the table. If they are, they're a genuine price check against AT&T and Comcast.
How much should I pay for 1 Gbps dedicated internet in downtown Detroit?
On-net in a competitive downtown or Corktown building, expect $1,050 to $1,455 a month retail on a 36-month term. Everstream and Lumen will quote at the lower end when they want the deal. If you're being quoted above $1,500 on-net, you're paying tier B pricing in a tier A market and should push back or quote a second carrier.
Will Ezee Fiber actually change pricing in Detroit?
Probably yes, but not everywhere and not immediately. Their announced build is FTTP across Metro Detroit with business service up to 100 Gbps. New overbuilders typically price 15 to 25 percent below incumbents to win the first wave of customers. If your renewal hits in 2026 or 2027, ask AT&T and Comcast to sharpen their pricing knowing Ezee is coming to your block.
Why is my Comcast bill higher than the contracted MRC?
Equipment rental, static IP charges, and carrier-invented surcharges like the Broadcast TV fee and Cost Recovery fees. None of those are government taxes, even though they're formatted to look like them. On a Detroit Comcast bill, those add-ons routinely total 15 to 25 percent above the quoted MRC. Pull the bill, line by line, and dispute anything you didn't intentionally order.
Do I need DIA or is business broadband fine for my Detroit office?
If your business runs hosted phones, real-time transactions, or remote workers depending on uptime, DIA's SLA is worth the premium. If you're a small office using cloud apps with tolerance for occasional slowdowns, business broadband at 500 Mbps to 1 Gbps from Comcast or Astound is usually plenty and runs $150 to $400 a month versus $1,000-plus for DIA.
How far in advance should I start renegotiating my contract?
Ninety days before contract end is the right window. That gives you time to pull competing quotes from AT&T, Comcast, Astound, and Everstream, and to catch any 60 or 90-day notice clause buried in your MSA. If you wait until 30 days out, most carriers will already consider you auto-renewed and you've lost your negotiating position.
