Business Internet Cost Estimator

Dedicated fiber vs. cable for business

Fiber delivers symmetric upload and download speeds, SLA-backed uptime guarantees, and fixed IP addresses with no shared contention ratio. Cable shares bandwidth with residential customers on the same line, which is why enterprise carriers have to overprovision and add cost to guarantee performance.

Why it costs more: Fiber requires dedicated routing to your site. Cable provides shared bandwidth. For business-critical applications (VoIP, live video, real-time data), fiber's consistency justifies the premium. For general web use, cable business-class may be acceptable if you verify the SLA is real.

What "business class" actually means

The term is loosely defined, but true business-class service includes:

• Static IP: Your address doesn't change (required for hosting, VPNs, integrations)
• Basic SLA: Uptime guarantee with compensation if it fails (usually 99.9%)
• Priority support: Faster response times than residential
• No throttling: You get your full speed, not "up to" speeds

What it doesn't mean: "Business class" doesn't guarantee faster speeds than residential or more reliability in practice. A residential fiber connection is often faster and more stable than cable "business class." Always verify SLA and uptime before committing.

When to add a second circuit

A single internet circuit is a single point of failure. Consider a second circuit (diverse carrier, different technology) if:

• VoIP is critical: Any outage means no phone service
• Multi-site operations: You run SD-WAN or need continuous remote access
• Cloud-dependent: SaaS or cloud-hosted applications go down with internet
• Retail/payment processing: POS systems offline = lost revenue
• Customer-facing: Websites, video conferencing, support chat require constant uptime

Cost of redundancy: A second circuit typically costs 60-80% of the primary. It's cheap insurance against catastrophic downtime. Many businesses add backup LTE (mobile hotspot) as a low-cost fail-safe.
