In the US, a standard 100-foot Cat6 Ethernet cable typically costs $15 to $40, while specialty Cat6A or Cat7 versions run from $60 up to $130.
The price of a 100 ft Ethernet cable depends on its category, shielding, and brand. For most home networks, a Cat6 cable in that $15–$40 range is all you need, since it comfortably handles gigabit speeds. Higher prices usually buy faster specs or tougher jackets, which only matter if your equipment can use them.
Price Differences By Cable Category
Sticking with Cat6 is the cheapest reliable option. Current U.S. listings show 100 ft Cat6 cables at Walmart for $14.95 and $16.49, and Best Buy sells its 100′ Cat-6 cable for $21.99. Target and Newegg fall in the same band, with prices like $29.99 and $22.99–$89.99 respectively. These differences come down to brand and jacket quality, not speed.
Moving up a category raises the cost noticeably. Insignia’s 100 ft Cat 6A cable sells for $39.99, while a Monoprice Cat7 cable runs $61.23. Premium Cat6A options can reach $129.99. Unless your router, switch, and devices all support 10-gigabit networking, that extra money buys no real speed gain.
| Category | Typical Price Range | Best For |
|---|---|---|
| Cat6 | $15 – $40 | Gigabit home networks |
| Cat6A | $40 – $130 | 10-gigabit short runs |
| Cat7 | $60 – $90+ | Future-proofing, shielded runs |
Does 100 Feet Affect Performance?
A 100 ft cable falls well inside the 100-meter (328 ft) channel limit for twisted-pair Ethernet, so length itself won’t slow you down. The standard spec allows a 90-meter permanent link plus 10 meters of patch cordage, and your 100 ft cable sits comfortably under that ceiling.
Actual speed depends on the cable category and the ports on the devices at both ends. According to Wikipedia’s Category 6 cable specifications, Cat6 supports 10/100/1000BASE-T up to 100 meters and can handle 10GBASE-T at shorter distances. Cat6A boosts that to 500 MHz and supports 10GBASE-T across the full 100-meter run.
Choose The Right 100 ft Cable
Match the category to the speed you actually need. For standard gigabit internet from a router to a PC, console, or TV, Cat6 is the practical pick. Only step up to Cat6A or Cat7 if you run a 10-gigabit network or need extra shielding against interference.
Check the jacket rating before buying for outdoor or in-wall runs. Standard PVC cables suit indoor use; outdoor, direct-burial, and riser-rated versions cost a bit more but handle those conditions safely.

FAQs
Is Cat6 fast enough for gaming?
Yes. Cat6 supports gigabit speeds, which exceeds what most internet plans deliver and adds no measurable latency for online gaming. A 100 ft Cat6 cable is plenty for a console or PC connected to a router.
Can a 100 ft cable cause signal loss?
No practical signal loss at that length. Ethernet is rated for 100 meters, so a 100 ft run is only about a third of the limit. Quality issues, not length, cause most connection problems.
What’s the difference between Cat6 and Cat6A?
Cat6A runs at 500 MHz and supports 10-gigabit speeds over the full 100-meter distance. Cat6 handles 10-gigabit only at shorter lengths. At 100 ft, both work fine for standard home use.
