Buyers typically pay for wire by type, gauge, insulation, and length, with main drivers including material grade, installation method, and local labor rates. This article outlines the cost ranges and price drivers for common electrical wiring used in residential work, focusing on cost and price details to help budgeting.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| NM-B Romex 14/2 per ft | $0.25 | $0.40 | $0.60 | Most basic branch wiring, indoor dry locations |
| NM-B Romex 12/2 per ft | $0.50 | $0.75 | $0.90 | Higher ampacity for general circuits |
| NM-B Romex 10/2 per ft | $0.90 | $1.25 | $1.80 | Used for higher load circuits; cheaper than armored options |
| Individual THHN per ft (conduit) | $0.25 | $0.60 | $1.20 | Wire inside conduit, often in walls or outdoors |
| 8–12 AWG THHN in conduit per ft | $0.40 | $0.95 | $2.00 | For feeders and outlets inside conduit |
| Electrical tape and connectors per project | $2 | $8 | $25 | Assorted fittings and splices |
Overview Of Costs
Typical price ranges include both total project costs and per unit costs, with assumptions such as standard residential wiring, indoor dry locations, and typical labor conditions. For a small update, expect wire material plus basic fittings. Larger runs, extra protection, or outdoor wiring can push totals higher.

Cost Breakdown
Materials cover Romex NM-B types and THHN in conduit. Prices escalate with gauge size, insulation, and whether the run requires specialty insulation or moisture protection. For example, 14/2 NM-B is cheaper than 10/2 NM-B, reflecting ampacity and conductor count.
Labor is driven by crew size, access, and complexity. Small runs in open basements cost less than long, hidden, or attic routes. Expect labor to account for roughly 40%–70% of a mid sized project when permits and inspections are not required.
Permits can add costs in some jurisdictions, especially when a permit is needed for new circuits or service upgrades. In regions with strict code enforcement, permit fees may range from $50 to several hundred dollars depending on project scope.
Delivery/Disposal includes hauling away waste and any fasteners or fittings. Large jobs may incur additional charges for bulk material handling.

Factors That Affect Price
Wire type and gauge are primary price levers. NM-B Romex is generally cheaper per foot than THHN in conduit, but overall costs depend on route and protection needs. For long runs, upgrading from 14/2 to 12/2 or 10/2 increases material costs but may reduce future upgrade work.
Installation complexity includes access to ceilings, walls, and outdoors. Conduits, cement walls, or exterior exposure raise both material and labor costs due to protection requirements and more challenging routing.
Local codes and permits vary by city and county. Some jurisdictions require inspections and permit fees that raise the project total but may ensure a safer, code compliant install.
Environmental and humidity factors influence wire choice, particularly outdoors or in damp basements where insulation and jacket types add cost.
Regional Price Differences
Prices vary across the United States by region. In the Southeast and Midwest, average material prices for NM-B are typically at or below national averages, while major coastal metro areas show modest premiums due to distribution costs and labor demand. Rural markets often present the lowest ranges, while urban core markets may span higher ranges because of access and permit processes.
Scenario view:
– West Coast urban: material costs +10–25% vs national averages
– Mountain states suburban: near national averages
– Rural Southeast: material costs −5 to −15% of national averages
Labor & Installation Time
Labor hours depend on run length and accessibility. A basic home run from a panel to a reachable outlet might need 1–2 hours, while mid sized projects with multiple circuits can require 6–12 hours of skilled labor. Use a rough rule for budgeting: 20–40% of total project cost goes to labor on straightforward installs, with higher shares for detailed routing or multiple floors.
Typical crew rates: electricians in non-union markets often bill $65–$120 per hour, plus any travel time. In high demand urban areas, rates can rise to $140–$180 per hour for complex jobs. data-formula=”hours × rate”>
Real World Pricing Examples
Three scenario cards show typical wiring projects with system scopes and reflect both per foot and total project costs. Each includes assumptions about region, run length, and labor hours.
Basic project: replace two outlets and add one new circuit with 14/2 NM-B in a single story home. Run length: 40 ft; labor: 3 hours. Materials: $12; Labor: $210; Permits: $0; Total: $230–$260; Price per ft: $5.75–$6.50.
Mid-Range project: upgrade lighting and add three new outlets with 12/2 NM-B; 120 ft total run; labor: 6.5 hours. Materials: $120; Labor: $520; Permits: $60; Total: $700–$820; Price per ft: $4.25–$5.00.
Premium project: whole home with multiple circuits, exterior outdoor feeds, and 10/2 NM-B plus THHN in conduit for exterior runs; 350 ft total; labor: 14 hours. Materials: $480; Labor: $1,320; Permits: $200; Total: $2,000–$2,400; Price per ft: $5.70–$6.90.
Seasonality & Price Trends
Prices can shift seasonally. Peak construction seasons, especially spring and summer, may see higher labor demand and incremental price increases for materials. Off season, some contractors offer reduced rates to fill calendars. For planning, target early spring or late fall for scheduling to align with lower labor costs and more favorable permit processing times.
data-formula=”seasonal_adjustment”> Pricing stability varies by region and contractor. Buyers should request formal quotes with itemized line items to compare between providers and to capture any seasonal adjustments.
