What Does Business Fiber Internet Actually Cost?

The short answer: it depends heavily on your location and the infrastructure already in place at your building. Unlike consumer broadband with published pricing, dedicated business fiber is quoted on a per-address basis. Two businesses two miles apart in the same city can receive dramatically different pricing depending on which carriers have lit fiber nearby.

That said, here are the realistic ranges you should expect in 2026 for dedicated fiber internet access (DIA) with a business-grade SLA:

  • 100 Mbps dedicated fiber: $300 – $600/month in most markets
  • 500 Mbps dedicated fiber: $500 – $900/month in most markets
  • 1 Gbps dedicated fiber: $600 – $1,400/month depending on carrier and location
  • 10 Gbps dedicated fiber: $1,800 – $5,000+/month for high-bandwidth enterprise needs

These ranges assume a 3-year contract with standard SLA. Month-to-month pricing is typically 30 to 50 percent higher. Term length, contract structure, and the number of carriers competing at your address are the biggest variables that move the number.

The most important thing to understand: if you're currently paying for dedicated fiber and haven't gotten competitive quotes in the last 18 to 24 months, you're almost certainly overpaying. Carrier pricing in most markets has declined significantly as fiber infrastructure buildout has accelerated.

Dedicated Fiber vs. Business Broadband: Which Do You Need?

Not every business needs dedicated fiber, but many that do are still running on shared broadband. Understanding the difference is critical to making the right decision.

Shared Broadband

  • Bandwidth shared with other customers
  • Speeds slow during peak hours
  • Asymmetric (upload much slower than download)
  • Limited or no SLA
  • Lower monthly cost

Dedicated Fiber (DIA)

  • Bandwidth guaranteed — yours alone
  • Consistent speeds 24/7
  • Symmetrical upload and download
  • SLA-backed uptime (99.9–99.999%)
  • Priority support and MTTR guarantees

Dedicated fiber is the right choice for any business where reliable internet is mission-critical. If an outage or slowdown costs you more per hour than the premium over broadband costs per month, the math strongly favors DIA. This includes healthcare practices, law firms, financial services companies, call centers, manufacturers running cloud-connected ERP systems, and any business with a high-volume video or VoIP environment.

What Drives Business Fiber Internet Pricing

Understanding what moves the price helps you evaluate quotes more intelligently — and negotiate better terms.

Location and On-Net vs. Off-Net

The single biggest price driver is whether a carrier already has fiber infrastructure in or near your building. An "on-net" building — one where a carrier already has lit fiber — can be priced and provisioned quickly, often at significantly lower rates. An "off-net" location requires construction, which adds cost, time, and sometimes a non-recurring charge (NRC). Our analysis identifies exactly which carriers are on-net at your address before any quotes are generated.

Contract Term

Month-to-month pricing typically runs 40 to 60 percent above the 3-year term rate. Most businesses choose a 2 or 3-year term to access the best pricing. We'll model the different term scenarios for you so you can make an informed decision about the tradeoff between savings and flexibility.

Bandwidth Tier

Price doesn't scale linearly with speed. The jump from 100 Mbps to 1 Gbps is rarely a 10x increase in cost — it's typically 2 to 3x. This means bandwidth per dollar often improves significantly at higher tiers, and many businesses are underbuying bandwidth relative to what they'd gain in performance and future-proofing.

Number of Competing Carriers

Markets with multiple fiber providers at a given address tend to have lower prices due to competition. Markets with one dominant carrier — often the incumbent telco — tend to have higher prices. Knowing how many qualified carriers are available at your address is therefore key intelligence before you begin any negotiation.

SLA Level

A 99.9% uptime SLA allows about 8.7 hours of downtime per year. A 99.999% ("five nines") SLA allows about 5 minutes. The premium for five-nines varies by carrier and market, but it's often 15 to 30 percent above a standard SLA circuit. For most businesses, 99.9% or 99.99% is the right balance of cost and reliability.

How Discover Communications Gets You Better Fiber Quotes

When you contact a fiber carrier directly, you're talking to a sales representative whose job is to close a deal at the best margin for that carrier. When you work with Discover Communications, you're working with an advisor whose entire value proposition is finding you the most competitive pricing across every carrier at your address.

We have active quoting relationships with over 200 carriers, including every major national fiber provider and dozens of regional and metro fiber operators that many businesses have never heard of. Our AI-assisted analysis system cross-references infrastructure data and current pricing to identify every qualified option — then our advisors apply market knowledge and carrier relationships to ensure you're getting pricing that reflects what the market actually offers, not what a carrier wants you to pay.

The entire process is free. We're compensated by the carrier you choose, at no markup to your rate.

What Information We Need to Quote Fiber at Your Address

Getting accurate fiber quotes requires just a few pieces of information. The more context you provide, the better calibrated our recommendations will be:

  • Your business address — This is the most critical input. We use it to identify on-net carriers and run the initial infrastructure lookup.
  • Required bandwidth — A starting point (e.g., "we need at least 500 Mbps") or current speed if you're looking to match or exceed what you have.
  • Current provider and monthly cost — Knowing what you're paying now helps us prioritize options that represent real savings.
  • Contract expiration date — This helps us understand your timeline and flag any urgency around notice periods.
  • Any specific requirements — SLA minimums, IPv4 requirements, BGP routing, static IP blocks, or compliance considerations.
