Cost of Ethernet cable

The cost of Ethernet cable varies widely from $0.05 to $6.00 per foot for the cable alone, depending on the type. Each cable type offers various benefits in terms of speed, bandwidth, and signal quality. The table below details the average material cost per foot for common Ethernet cable types:

Cost of Ethernet cable
Cable type Average cost per foot*
Coaxial cable $0.05 – $0.20
Twisted pair cable $0.10 – $1.10
Fiber optic cable $1.00 – $6.00

*Material costs only; installation not included

Coaxial cable

Coaxial cable costs $0.05 to $0.20 per foot for the materials alone. Coaxial cable is commonly used for cable TV and internet connections and is made up of a central wire surrounded by insulation, a metal shield, and an outer layer. This type of cable protects signals from interference and can transmit data over long distances, making it suitable for both indoor and outdoor use.

Twisted pair cable

Twisted pair cable, commonly known as CAT (Category) cable, consists of insulated copper wires twisted together. It's widely used in residential settings for internet connections, home networking, and phone lines. CAT cables typically cost $0.10 to $1.10 per foot.

These cables come in two main varieties: Unshielded Twisted Pair (UTP), which is more common and cost-effective for most home uses, and Shielded Twisted Pair (STP), which offers better protection against interference but is more expensive.

The most commonly used CAT cables for home networks include:

  • CAT-5e: An enhanced version of CAT-5, supporting speeds up to 1 Gbps, this type is ideal for basic internet usage and is widely used in residential settings due to its affordability and sufficient performance for standard needs.

  • CAT-6: Offering speeds up to 10 Gbps over shorter distances (up to 55 meters), this cable is suitable for households that require higher bandwidth for activities like gaming and streaming.

  • CAT-6a: Similar to CAT-6, this cable type provides better shielding and supports 10 Gbps speeds over longer distances (up to 100 meters). It's a good choice for future-proofing your home network.

  • CAT-7: The most expensive type, CAT-7 supports speeds up to 10 Gbps with enhanced shielding, making it suitable for environments with a lot of data traffic, although it may be more than necessary for typical home use.

For most home users, CAT-5e or CAT-6 cables are sufficient, while CAT-6a offers a solid option for those looking to invest in a more robust solution.

Fiber optic cable

Fiber optic cable uses thin strands of glass or plastic to transmit data as light pulses. It offers several advantages:

  • Extremely high bandwidth and data transmission speeds

  • Long-distance transmission with minimal signal loss

  • Immunity to electromagnetic interference

While traditionally more expensive than copper cables at $1 to $6 per foot, fiber optic is becoming increasingly common in residential areas, offering future-proof speeds for home networks.

What affects the cost of Ethernet cable installation?

Ethernet installation involves several key components that work together to create a functional network. These elements include cables, Ethernet ports, network switches, routers, and modems. Understanding these components is essential when planning and budgeting for your Ethernet installation project.

Cost of Ethernet cable installation
Component Average installation cost*
Professional installation $50 – $130 per hour
Cables $0.10 – $0.60 per foot
Ethernet port $100 – $200 per port
Router $80 – $120
Modem $50 – $100
Network switch $10 – $100

*Estimated cost for 2,000 square foot home

  • Labor cost: For a large-scale project with 2,000 feet of cable and eight Ethernet connections, the electrical work alone costs $50 to $130 per hour or $1,500 to $5,000 total for the 30 to 40 hours needed to install Ethernet cable throughout an existing house.

  • Cable type: CAT cables cost between $0.10 and $1.10 per foot, with higher categories being more expensive. Fiber optic cables are generally pricier, ranging from $1.00 to $6.00 per foot, but they offer faster speeds and longer distances.

  • Ethernet ports or jacks: These are the outlets where devices connect to the network. It’s recommended to install at least two ports per room to accommodate multiple devices, with installation costs ranging from $100 to $200 per port, including materials and labor.

  • Router: A router costs $80 to $120 and directs internet traffic to your devices. Some models combine a router and modem. If you choose a wireless router, ensure it has good security features to protect your network from unauthorized access.

  • Modem: A modem costs $50 to $100 and connects your home network to the internet, controlling data speeds, bandwidth, and network reliability. Some internet service providers (ISPs) provide modems, but purchasing your own may offer better quality and speeds.

  • Network switch: Costs range from $10 to $100 for home models that allow multiple devices to connect to a network. Some routers have built-in switches, while others may need a separate switch. Using Power over Ethernet (PoE) switches can simplify the installation of smart devices by providing both power and data through a single cable.
