How to Estimate Electrical Work: A Guide for Electricians and Contractors
Electrical estimating is part math, part experience, and part knowing what's hiding in the walls. Get it wrong and you're working for free — or worse, paying to finish a job. This guide breaks down how to estimate electrical work accurately, whether you're bidding a service upgrade, a new construction rough-in, or a remodel.
The Two Types of Electrical Estimates
Unit pricing — you assign a flat price per item installed (per outlet, per circuit, per fixture). Fast and consistent once your numbers are dialed in.
Labor + material — you itemize labor hours and materials separately. More transparent, better for larger or complex jobs.
Most electricians use unit pricing for service calls and smaller jobs, and labor + material for larger installs. This guide covers both.
Unit Pricing: Building Your Numbers
Unit prices need to cover labor + material + overhead + profit. Here are industry benchmarks you can calibrate to your market:
| Item | Unit Price Range |
|---|---|
| Duplex outlet (new) | $150–$250 |
| GFCI outlet | $200–$300 |
| 20A circuit (new, <50 ft) | $300–$500 |
| 15A circuit (new) | $250–$400 |
| Standard switch | $100–$175 |
| 3-way switch | $175–$275 |
| Dimmer switch | $150–$225 |
| Recessed light (new construction) | $125–$200 |
| Recessed light (retrofit, existing ceiling) | $175–$300 |
| Ceiling fan (install only) | $125–$250 |
| 240V appliance circuit | $400–$700 |
| EV charger circuit + outlet | $500–$900 |
| Smoke detector | $100–$175 |
| Panel upgrade (100A→200A) | $1,800–$3,500 |
These are installed prices (material + labor + overhead). Your actual numbers depend on your local material costs and labor rate.
Labor + Material Estimating
Step 1: Identify the Scope
Walk the job and list every electrical item:
- New circuits needed
- Existing circuits being modified or extended
- Panel work (breakers, subpanels, upgrades)
- Low-voltage (CAT6, coax, speakers)
- Rough-in only, or rough-in + trim?
- Inspections and permits required?
Step 2: Estimate Labor Hours
Typical labor times for a journeyman electrician:
| Task | Time |
|---|---|
| Run new 14/2 circuit, <50 ft | 2–3 hrs |
| Run new 12/2 circuit, <50 ft | 2.5–3.5 hrs |
| Run 240V circuit | 3–5 hrs |
| Install outlet or switch (existing) | 0.5–1 hr |
| Install outlet or switch (new work) | 1–1.5 hrs |
| Install recessed light (new construction) | 0.5–0.75 hr |
| Install recessed light (retrofit) | 1–1.5 hrs |
| Install panel breaker | 0.25–0.5 hr |
| Panel upgrade (200A, includes meter base) | 6–10 hrs |
| EV charger circuit + install | 3–5 hrs |
| Permit and inspection coordination | 1–2 hrs |
Step 3: Price Materials
Material markup varies — most electricians mark up 20–35% over their supplier cost. Always charge retail on materials; your supplier discount is your margin, not the client's savings.
Key material costs to know:
- 14/2 NM-B wire: $0.35–$0.55/ft
- 12/2 NM-B wire: $0.55–$0.80/ft
- 10/2 NM-B wire: $0.90–$1.20/ft
- 200A main panel (Square D, Leviton): $250–$450
- 200A meter base: $150–$300
- Standard outlets (Leviton): $4–$8 each
- GFCI outlets: $15–$30 each
- Conduit (½" EMT): $1.20–$2.00/ft
Step 4: Add Permit and Inspection Costs
Electrical permits typically run $100–$500 depending on scope and jurisdiction. Always include permit fees as a line item — they're a real cost and not part of your overhead.
Sample Estimate: Basement Finish Electrical
Scope: 1,000 sq ft basement finish — rough-in only. 12 outlets, 6 recessed lights, 2 dedicated circuits (home office + mini fridge), 1 bathroom with GFCI, smoke detector.
| Line Item | Qty | Unit | Rate | Total |
|---|---|---|---|---|
| 15A circuits (outlets, lights) | 3 | circuit | $350 | $1,050 |
| 20A dedicated circuit (office) | 1 | circuit | $425 | $425 |
| 20A dedicated circuit (fridge) | 1 | circuit | $425 | $425 |
| Outlets — standard rough-in | 12 | each | $45 | $540 |
| GFCI outlet — bathroom | 2 | each | $65 | $130 |
| Recessed light rough-in | 6 | each | $40 | $240 |
| Smoke detector | 1 | each | $95 | $95 |
| Panel breakers (5) | 5 | each | $45 | $225 |
| Wire, boxes, staples, connectors | 1 | lot | $280 | $280 |
| Permit | 1 | job | $250 | $250 |
| Labor — journeyman (22 hrs @ $95) | 22 | hr | $95 | $2,090 |
| Subtotal | $5,750 | |||
| Overhead & profit (15%) | $863 | |||
| Total | $6,613 |
Sample Estimate: 200A Panel Upgrade
| Line Item | Qty | Unit | Rate | Total |
|---|---|---|---|---|
| 200A main panel (Square D) | 1 | each | $380 | $380 |

| Service entrance cable | 20 | ft | $4.50 | $90 |
| Ground rods + clamps | 2 | each | $35 | $70 |
| Misc hardware (wire, connectors) | 1 | lot | $75 | $75 |
| Labor — electrician (8 hrs @ $110) | 8 | hr | $110 | $880 |
| Permit + inspection | 1 | job | $350 | $350 |
| Subtotal | $2,070 | |||
| Overhead & profit (20%) | $414 | |||

What Most Electricians Get Wrong on Estimates
Forgetting travel time. If the job is 45 minutes away, that's 1.5 hours of drive time per day. Price it in or absorb it.
Not accounting for inspection delays. Rough-in passes, but the inspector wants changes before trim. Add buffer time on bigger jobs.
Underpricing wire runs in finished spaces. Fishing wire through finished walls takes 3–5× longer than new construction. If you're quoting a remodel, adjust your labor accordingly.
Using new-construction times on remodel work. Always ask: is this open framing or existing finished space?
Not getting the full scope before quoting. "While you're here, can you also..." kills profitability. Scope everything upfront.
