12/2 Romex price history shows substantial changes as copper prices, supply conditions, and retailer pricing have shifted. A standard 250-foot roll of 12/2 NM-B copper cable with ground currently commonly costs about $150-$230, while 100-foot rolls often run $65-$105; brand, store, region, and purchase date affect the price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 12/2 NM-B, 100 ft | $65 | $85 | $105 | Retail roll with copper conductors and ground |
| 12/2 NM-B, 250 ft | $150 | $190 | $230 | Common residential project size |
| 12/2 NM-B, 1,000 ft | $560 | $700 | $850 | Bulk pricing varies by supplier and brand |
| Historical 250-ft roll range | $60 | $140 | $240 | Indicative retail range across recent market periods |
What a 250-foot roll of 12/2 Romex costs now
For ordinary retail purchases, a 250-foot roll of 12/2 NM-B cable with ground generally falls between $150 and $230. A useful planning figure is about $190 per roll, or roughly $0.60-$0.92 per linear foot. That estimate covers the cable itself, not installation, fittings, electrical boxes, or permit charges.
Budget around $0.75 per foot for a standard 250-foot roll, then verify the current shelf or online price. Lower prices are more likely during promotions or at high-volume suppliers; premium brands and local inventory constraints can push the price toward the top of the range. Retail prices may also vary between a store’s website and its local branch.
“Romex” is widely used as a general name for nonmetallic-sheathed cable, though it is a brand name. The comparison here assumes 12-gauge copper conductors, two insulated conductors, a bare grounding wire, and standard NM-B construction suitable for permitted indoor residential applications. Cable with different conductors, packaging, or use ratings is not a like-for-like comparison.
Assumptions: U.S. retail pricing, standard 12/2 NM-B copper cable with ground, ordinary access, and no installation labor.
How 12/2 cable prices changed from 2015 onward
There is no single national historical price series for every brand and retailer. The ranges below are practical estimates for commonly sold 250-foot rolls, assembled from typical U.S. retail pricing patterns rather than a guaranteed record of a specific store’s past prices. Sale pricing, location, and stock can create wider differences.
| Buying period | Low | Average | High | Price context |
|---|---|---|---|---|
| 2015-2019 | $60 | $80 | $110 | Generally lower copper and retail costs |
| 2020-2021 | $90 | $145 | $210 | Supply disruptions and rising copper costs |
| 2022 | $120 | $180 | $240 | Elevated material and distribution costs |
| 2023 | $95 | $145 | $200 | Prices eased in some markets, with variation |
| 2026-2026 | $120 | $180 | $230 | Retail prices remained above many pre-2020 levels |
The broad pattern is a lower pre-2020 baseline, a sharp run-up in 2020-2022, and uneven easing afterward. These ranges describe approximate roll prices, not inflation-adjusted values. A roll that cost $80 several years ago may represent a higher price in today’s dollars than its face value suggests.
Historical comparisons also depend on roll length. A 100-foot package can have a higher per-foot price than a 250-foot roll, even if its total price is lower. Comparing a small package’s ticket price with the total for a larger roll can make the market appear to have changed more than it did.
What copper and cable manufacturing add to the quote
Copper is the most visible commodity influence, but it is not the entire retail price. A cable maker must draw copper into conductors, apply insulation, add a protective outer jacket, package the cable, and ship it through distributors and retailers. Changes in energy, freight, labor, and inventory costs can affect the shelf price even when copper itself moves only modestly.
| Cost component | Typical contribution | What changes the amount | Practical implication |
|---|---|---|---|
| Copper conductors | $45-$95 per 250 ft | Copper market, conductor weight, and purchasing date | Largest commodity-sensitive component |
| Insulation and jacket | $20-$45 per 250 ft | Material inputs and manufacturing specification | Standard cable differs from specialty ratings |
| Manufacturing and packaging | $15-$35 per 250 ft | Plant costs, production volume, and packaging | Brand and supply availability can matter |
| Distribution and retail | $30-$70 per 250 ft | Freight, stocking, overhead, and retailer margin | Local price can diverge from online listings |
A shelf price includes more than the metal value of its copper. The component amounts are illustrative estimates, not published manufacturer cost accounts; the categories overlap as products pass through the supply chain. They help explain price movement, but should not be added to predict a specific store’s selling price.
Wire is sold by gauge, conductor count, jacket type, and roll length. A 12/2 cable is not interchangeable with 14/2 simply because both look similar: conductor size affects the circuit application and must match the design, breaker, code, and electrician’s instructions. A lower price for a different specification is not a valid savings comparison.
Why copper prices and 250-foot roll size matter
Changes in copper markets can influence wire pricing, but cable prices do not always rise or fall at the same pace. Manufacturers and distributors may hold inventory purchased at older rates, while retailers may update prices based on replacement costs, availability, and competition. This lag is one reason two stores can show different prices on the same day.
Roll length also affects the cost per foot. A 100-foot roll priced at $85 costs $0.85 per foot; a 250-foot roll at $190 costs $0.76 per foot. A 1,000-foot roll at $700 works out to $0.70 per foot, but that lower unit rate is useful only if the project will use the cable and the purchaser can store it safely.
Compare the price per linear foot, not just the roll total. For a project needing 120 feet, buying a 250-foot package may reduce the unit rate but leave 130 feet unused. Return rules differ, and cut or opened electrical materials may not be returnable. Measure the route and allow a reasonable amount for routing and termination without overbuying.
Pricing can also differ by brand and certification details. Confirm that the label identifies the required cable type and rating; do not assume that a lower-priced product is suitable for a particular location. Outdoor, wet-location, underground, or other special conditions may require a different wiring method altogether.
Regional retail prices from big cities to rural stores
For a standard 250-foot roll, metropolitan markets can run roughly 5%-15% above a national midrange, while competitive suburban markets may sit near the baseline or about 5% below it. Rural stores may charge 5%-20% more when inventory is limited or replenishment freight is higher. These are directional differences, not fixed regional surcharges.
For a $190 baseline roll, a 10% local premium means about $19 more. Taxes are additional where applicable and are usually based on the local sales-tax rules. Online listings can appear cheaper, but delivery charges, pickup availability, and the need to buy a full roll may change the final comparison.
Markets with several home-improvement stores and electrical suppliers may have more frequent promotions or price matching. In areas with fewer outlets, a contractor supply counter may carry the needed grade but quote a higher one-roll price. Bulk or trade pricing is not guaranteed for occasional purchases, and some suppliers impose minimum order quantities.
When checking local prices, compare the same gauge, conductor configuration, cable rating, and roll length. A sale on a 100-foot roll should not be compared directly with a 250-foot listing. Confirm whether delivery is included and whether the posted price reflects stock at the branch serving the project.
When a 100-foot roll beats a bulk cable purchase
Small repair or short-run projects may be more economical with a 100-foot roll, even at a higher per-foot rate. At an illustrative $85, that package costs $0.85 per foot. A 250-foot roll at $190 costs $0.76 per foot, while a 1,000-foot roll at $700 costs $0.70 per foot. Those unit prices are estimates; actual listings can differ.
| Package | Estimated price | Approximate rate | Typical purchasing trade-off |
|---|---|---|---|
| 100 ft | $65-$105 | $0.65-$1.05 per ft | Lower upfront cost for limited work |
| 250 ft | $150-$230 | $0.60-$0.92 per ft | Common balance of price and quantity |
| 1,000 ft | $560-$850 | $0.56-$0.85 per ft | Lower rate, higher spend and storage needs |
The lowest unit price is not always the lowest project cost. Estimate the actual cable route before buying, and account for leftover stock, secure storage, and return restrictions. If several permitted projects use the same specification, a shared bulk order may make sense, provided the cable remains protected from damage and moisture.
DIY work can reduce labor charges, but electrical work carries shock and fire risks and is subject to local code and permit rules. The cable price does not include boxes, connectors, staples, circuit protection, testing, or correction of existing wiring problems. A qualified electrician can confirm the required cable and scope before material is purchased.
How installation labor changes the total project bill
Material cost is only one part of a wiring project. Electricians commonly charge about $75-$150 per hour, with local minimums or service-call fees that may add $75-$200. A straightforward new cable run can take about 2-5 labor hours, while concealed routes, finished walls, panel work, or troubleshooting can extend the job significantly.
A simple 3-hour task at $100 per hour adds $300 in labor before materials and other charges. That illustration does not predict a particular quote; crew size, travel, access, testing, and scope determine the billed amount. Some electricians quote a flat project price rather than an hourly rate.
Running cable through an unfinished basement or accessible attic may be less labor-intensive than fishing a route through finished walls. Long runs, multiple bends, crowded framing, and work near insulation can add time. If drywall repair or painting is needed afterward, it may be priced separately and can exceed the cost of the cable itself.
For a quote comparison, ask whether the price includes the wire, boxes, connectors, circuit connection, testing, permit handling, and cleanup. A low labor figure may exclude material or wall restoration. A written scope makes estimates easier to compare and helps prevent extra charges when site conditions differ from the original assumptions.
Ways to lower the 12/2 cable bill without risking the job
First, confirm the required cable specification and measure the route with the electrician or project plan. Avoid substituting a smaller gauge or an unsuitable cable type to save money. The correct circuit design and cable choice depend on the application and local electrical code, not simply on which roll has the lowest sticker price.
Match package size to measured use before chasing a bulk discount. A 100-foot roll can cost more per foot but less overall for a modest job. For a larger project, compare the 250-foot and 1,000-foot rates, then include delivery, leftover material, and storage in the calculation.
Check several nearby retailers and electrical suppliers for the identical product and roll length. Look for a sale or price match, but verify that the item is in stock and that pickup or shipping does not erase the savings. If material is purchased for an electrician’s job, confirm who supplies it and whether customer-provided cable affects the workmanship warranty.
Reduce labor rather than compromising materials: clear access to the work area, move stored items away from the route, and settle the scope before the appointment. Ask whether related work can be completed during the same visit to avoid repeated minimum charges. Do not open walls or alter existing wiring unless the contractor agrees that the preparation is safe and appropriate.
Finally, ask the contractor to separate cable, labor, permit, and repair charges in the estimate. That breakdown reveals whether an unusually high total reflects expensive wire, difficult access, additional circuit work, or wall restoration. A quote should explain any premium for urgent scheduling, specialty cable, or unexpected code corrections.
