The price to run electrical wire per foot varies by type, insulation, and installation conditions. Buyers should expect to pay for the wire itself plus potential labor and permits. This article breaks down typical costs for common gauges and scenarios, helping readers estimate the total cost of electrical wire per foot.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Wire material (copper, THHN, NM-B) | $0.20 | $0.60 | $1.50 | Per foot, depending on gauge and type |
| Conduit or sheathing per foot | $0.15 | $0.40 | $1.20 | PVC or metal, length adds up |
| Labor for running wire per foot | $0.50 | $2.50 | $6.00 | Varies by access and location |
| Permits and inspections (per project) | $50 | $200 | $600 | Allocated across total length |
| Delivery/poor access surcharge | $0 | $0.20 | $0.75 | Per foot in hard-to-reach sites |
Assumptions: Midwest or typical U.S. labor rates, standard copper conductors, normal attic/basement routing, residential installation.
Direct price ranges for common wire types by foot
Wire type and gauge drive most of the per-foot price. In general, copper THHN in conduit costs more per foot than NM-B Romex for interior residential runs. Copper THHN in 12 AWG ranges from $0.60 to $1.20 per foot, while 14 AWG THHN typically lands around $0.40 to $0.90 per foot. NM-B 12/2 or 14/2 cable for interior branch circuits often runs about $0.35 to $0.90 per foot. Larger gauges like 6 AWG used for feeders or range circuits push costs higher, generally $2.00 to $5.00 per foot including armor or conduit support in certain setups.
Cost drivers by insulation and jacket type
The insulation and jacket add predictable premiums. For example, outdoor-rated or UV-resistant jackets add 20%–40% to per-foot material costs, and armored cable (AC/Armor cable) adds more upfront material cost and labor complexity. Indoor NM-B cable without armor is typically the least expensive option per foot.
Regional price differences for wire per foot
Labor rates and material sourcing vary by region. Coastal cities and high-cost metro areas can see per-foot wire costs higher by about 10%–25% compared with rural Midwest markets, due to shipping, demand, and local wage scales. Expect roughly $0.10–$0.40 per foot variation only from regional factors.
Labor impact: per-foot cost of installation vs raw wire
Labor adds a meaningful portion of the total per-foot cost. If routing is straightforward in open attic space, labor may run about $0.50–$2.50 per foot. In constrained spaces, crawl spaces, or under floors with long lengths, labor can reach $4.00–$6.00 per foot. Choosing simple routing can halve the installed price per foot versus complex paths.
Per-foot costs by project scope: outlets, feeders, and service wires
Project scope matters. Small interior runs to new outlets may sit near $0.60–$1.20 per foot for copper THHN in conduit, while feeder runs from a panel or service entrance can range $2.00–$4.50 per foot depending on gauge and conduit. Service entrance wires or feeders have higher per-foot costs due to larger gauges and safety requirements.
Outdoor, underground, and basement runs
Outdoor or underground wiring commands higher costs. Direct burial cable and conduit with proper protection can push costs to $1.20–$3.50 per foot for the cable portion, plus installation complexities. Basement and crawlspace runs often sit between indoor NM-B and outdoor conduit ranges depending on exposure and moisture protection. Weatherproofing and trenching add to overall per-foot pricing.
Per-foot cost breakdown: materials, labor, and permits
The price composition often looks like this: materials $0.25–$1.50 per foot, labor $0.50–$4.50 per foot, and permits/inspection $0.02–$0.30 per foot when averaged across a project. Labor dominates in hard-to-reach paths and long runs.
| Cost Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (wire, conduit, fittings) | $0.25 | $0.80 | $2.50 | Gauge and jacket dependent |
| Labor to pull and secure | $0.50 | $2.50 | $6.00 | Access and routing drive variation |
| Permits and inspections | $0.02 | $0.15 | $0.30 | Spread across project length |
| Delivery/handling | $0.00 | $0.10 | $0.50 | Site access dependent |
| Subtotal per foot | $0.79 | $3.60 | $9.30 | Composite pricing |
Variables that most shift the final price per foot
Two key drivers are gauge size and environment. Gauge size directly scales copper cost: 14 AWG sits lower, 8 AWG sits higher. Environment matters: indoor, outdoor, and direct burial add material and protection costs. Gauge and routing complexity together determine most of the variance.
How to trim per-foot costs without compromising safety
Cost-saving moves include planning a single run for multiple outlets, using standard conduit sizes, and avoiding premium jackets unless required. Consolidating scope, scheduling during slower seasons, and comparing quotes from licensed electricians also helps. Bundle tasks where feasible to reduce repeated site visits.
Real-world quote scenarios with per-foot details
Example A: 120 feet of 12 AWG THHN in conduit for a garage circuit. Materials $0.95/ft, labor $2.20/ft, permits $0.15/ft. Total per foot $3.30; total project around $396.
Example B: 60 feet of outdoor direct burial 10 AWG with conduit. Materials $1.25/ft, labor $3.00/ft, trenching $0.40/ft, permits $0.20/ft. Total per foot $4.85; total project around $291.
Example C: Indoor NM-B 14/2 run of 40 feet to add a dimmer circuit. Materials $0.40/ft, labor $1.80/ft, permits $0.08/ft. Total per foot $2.28; total project around $91.
Warranty, code, and ongoing costs that affect the price per foot
Factory warranties on wire are standard, but the overall project warranty depends on the installer. Codes and inspections may require updates to panel or grounding, indirectly increasing per-foot costs through additional materials or labor. Ongoing maintenance costs are typically low but can rise if upgrades are needed later.
