How to price and estimate electrical work, step by step
To price electrical work, count the openings, multiply them by your labor units (hours per opening) and your loaded labor rate, add materials from a real list plus 5 percent for the small parts, add the permit, then divide the total by one minus your target margin. The worked example below prices a 26 opening basement at $3,576, about $138 an opening. The mistake that sinks newer shops is marking cost up by a percentage instead of dividing by the margin.
Step by step
- Walk the job and count every opening. Electricians price residential work by the opening: every box that holds a receptacle, switch or fixture is one. Walk each room and count them, then note anything that needs its own circuit, like a microwave, dishwasher or EV charger. A 26 opening basement and a 40 opening basement are different jobs, and the count is the spine of the whole estimate.
- Split rough-in, trim and service work. Rough-in is boxes and wire before drywall, trim is devices and fixtures after, and service work is anything touching the panel or meter. Each phase has its own labor and its own inspection, and pricing them apart makes billing by stage easy when the homeowner or builder pays as you go.
- Set your labor units. A labor unit is the hours one opening takes, rough-in and trim together. Get yours from your own jobs: hours billed divided by openings on your last five. This guide uses 45 minutes an opening for remodel work in open framing as its example. Old work fished through finished walls takes more, so keep a separate unit for it instead of averaging the two.
- Know your loaded labor rate. Labor cost is hours times a loaded rate: the wage plus payroll taxes, workers comp and the truck, per billable hour. The example uses $85 an hour. If you are the one billing, the electrician hourly rate calculator works your rate out from your own yearly pay, overhead, truck, insurance and billable hours. Use a cost rate here, not your billing rate, because the margin step below adds overhead and profit.
- Price devices, boxes and wire from a real list. Use current numbers, not memory: a duplex receptacle runs about $1.75, a single-pole switch $2.10, a GFCI or a dimmer about $22, a recessed downlight $19.50, and a device box or cover plate $0.85. Figure wire by run length: mixed 12/2 and 14/2 NM averages about $0.52 a foot, so a basement that eats 300 feet is $156 of cable. Then add 5 percent for staples, connectors and the small stuff.
- Add the code items and the permit. Code drives real dollars: a dual-function AFCI/GFCI breaker runs about $58 against $9 for a standard one, and bedrooms trigger smoke detector updates at about $23 each. Look up your jurisdiction's permit fee and put it on the estimate as its own line, with the inspection trips counted in the labor.
- Divide by one minus your margin. Add materials, labor and the permit to get job cost, then divide by one minus your target margin. At a 35 percent margin, a $2,324.31 job cost divides by 0.65 to $3,575.86. Multiplying the same cost by 1.35 gives $3,137.82, which is only a 26 percent margin, and the difference is your profit handed to the customer.
- Write exclusions, then send it the same day. State what is not included: drywall patching, painting, fixtures above an allowance, and utility company charges. Then send the estimate while the walkthrough is fresh, because homeowners call more than one electrician and the first professional number tends to frame the decision. A line-item estimate the client can e-sign from a text beats a number on a business card.
The electrical pricing formula
Job cost = (materials x 1.05) + (openings x hours per opening x loaded labor rate) + permit. Price = job cost / (1 - target margin), so a 35 percent margin means dividing by 0.65. Margin is not markup: $100 of cost marked up 35 percent sells at $135, and $35 of profit on $135 is a 26 percent margin, which is why dividing is the honest math. If the labor rate you plug in is already a billing rate that carries overhead and profit, as the recommended rate from an hourly rate calculator does, price labor at that rate and apply the margin to materials and the permit only.
A 26 opening basement finish. Materials: 12 duplex receptacles at $1.75 is $21.00, 6 single-pole switches at $2.10 is $12.60, 8 recessed downlights at $19.50 is $156.00, 18 device boxes and 18 cover plates at $0.85 each is $30.60, 300 feet of mixed 12/2 and 14/2 NM cable at $0.52 is $156.00, and 2 dual-function AFCI/GFCI breakers at $58 is $116.00, for $492.20. Add 5 percent for small parts: $516.81. Labor: 26 openings at 0.75 hours is 19.5 hours, and at an $85 loaded rate that is $1,657.50. Add a $150 permit as the example fee. Job cost is $2,324.31. Divide by 0.65 for a 35 percent margin and the price is $3,575.86, call it $3,576, or about $138 an opening.
Cost factors electricians price for
Old work versus new construction
Fishing cable through finished walls and insulated ceilings takes far longer per opening than drilling open studs. Plaster and lath, blocking and two-story runs push it further. Keep a separate labor unit for remodel openings rather than pricing them off new-construction numbers.
Panel capacity
If the existing panel is full or a fused relic, the job grows a service upgrade. A 200 amp main panel alone runs about $265 in material before the meter, breakers and utility coordination, and the labor is a full day. Never absorb a panel discovery into a flat bid; write it as its own line.
Code triggers
Touching a circuit often obligates you to bring it to current code. AFCI and GFCI protection, tamper-resistant receptacles and smoke and CO coverage add real material cost, with a dual-function breaker near $58 against $9 for a standard one. Know your jurisdiction's amendments before you commit to a number.
Ceiling height and access
Vaulted ceilings, tight attics with blown insulation and crawlspaces slow every run. A recessed light on a 16 foot ceiling needs staging or a lift, and the lift shows up as a rental line. Access is the difference between a quick fixture and an hour and a half on one.
Occupied homes
Working around furniture, floor protection, daily cleanup and a homeowner with questions slows the crew, and power shutdowns have to be scheduled around the family. Put that time in the labor units for occupied jobs rather than hoping to outrun it.
Frequently asked questions
How much should I charge per opening as an electrician?
Build it from your own costs: devices, boxes and wire for the opening, your labor units times your loaded rate, then the margin. The worked example on this page lands at about $138 an opening for a basement with eight cans. If your per-opening price only covers materials and the wage on the check, the truck and the insurance are coming out of your pocket.
How do I calculate electrical labor cost?
Openings times hours per opening gives the hours, and hours times a loaded rate gives the cost. The loaded rate is the wage plus payroll taxes, workers comp and the truck, spread over the hours you actually bill. In the example, 26 openings at 45 minutes is 19.5 hours, and 19.5 hours at $85 is $1,657.50.
What margin should I price electrical work at?
Work it out from your own books: last year's overhead as a share of revenue, plus the profit you want to keep. That total is your target margin, and you divide job cost by one minus it. The example uses 35 percent, which means dividing by 0.65. A thin markup feels safe and is a slow leak, because one callback or one code surprise erases it.
Should I include light fixtures in the bid or use an allowance?
Use an allowance for decorative fixtures the homeowner picks, and price the installation labor separately so a $400 chandelier choice does not blow up your number. Commodity items like recessed downlights at about $19.50 each are better carried as your own line items, since you control the product. Put the allowance amount in writing on the estimate.
Do I need a permit for a basement wiring job?
In most US jurisdictions, adding circuits or openings needs an electrical permit with at least a rough and a final inspection. Fees vary by city and job size, so look up your fee schedule and put the permit on the estimate as its own line. An unpermitted job can stall the sale of the house later and land back on you.
Can software build this estimate for me?
Staxen's estimator, Eddie, works from the job you describe out loud: it drafts a priced line-item estimate you review and send as a text or email link the client can e-sign on their phone. Staxen is $59 per month per AI employee, or $149 per month for all three, and the first 7 days are free in the app.
