Electrical Estimating Guide
Electrical wiring, panel upgrades, and installation estimating for residential and commercial projects.
Overview
Electrical estimating covers a wide range of work from simple outlet additions to complete commercial electrical systems. Bids typically account for wire runs, device counts, panel capacity, and code-required components like AFCI and GFCI protection. Labor represents the largest portion of most electrical bids, often 60-70% of total cost.
Common Projects
- Electrical panel upgrade (100A to 200A)
- Whole-house rewire
- New construction rough-in and trim
- EV charger installation
- Recessed lighting layout and installation
- Commercial tenant improvement electrical
Pricing Factors
- Number of circuits, outlets, and switches
- Panel amperage and number of spaces needed
- Wire gauge and run lengths
- Local code requirements (AFCI, GFCI, tamper-resistant)
- Conduit requirements (EMT, rigid, flexible)
- Height and accessibility of work areas
Materials List
- NM-B cable or THHN wire
- Electrical panels and breakers
- Outlets, switches, and cover plates
- Junction boxes and mud rings
- Conduit and fittings (EMT, PVC, flex)
- Wire nuts, connectors, and staples
- Recessed light housings and LED trims
- Ground rods and grounding wire
Estimating Tips
- Count every device (outlet, switch, light) and price per device for residential work — $150-$250 per device is a common range.
- Always verify panel capacity before bidding — an unexpected panel upgrade can add $2,000-$4,000 to a project.
- Include wire waste factor of 10-15% on every run to account for routing around obstacles.
- Factor in permit fees, inspection trips, and code-required testing in your overhead.
- Track your actual hours per device type to build accurate production rates over time.

FAQs
Common questions about electrical estimating
Most residential electricians estimate by counting devices (outlets, switches, lights) and pricing per device. A typical per-device price of $150-$250 covers labor, wire, box, device, and plate. Panel work, dedicated circuits, and specialty items are priced separately.
Journeyman electrician labor rates for estimating purposes typically range from $65-$120 per hour depending on region, with the fully burdened rate (including benefits, insurance, and overhead) often reaching $85-$150 per hour. Always use your actual burdened rate rather than industry averages.
A 200-amp panel upgrade typically costs $2,000-$4,500 installed, depending on whether the utility requires a new meter base and whether the existing wiring needs to be reworked. Include permit fees, utility coordination time, and a temporary power disconnect in your estimate. If the panel is in a finished space, add drywall repair and painting to your scope or exclude it clearly in writing.
