Question 1

How to calculate an electrical estimate?

Accepted Answer

Start with a thorough site assessment to determine scope and complexity. Measure circuit runs and calculate wire quantities with a 10-15% waste factor. List all materials needed (wire, conduit, boxes, breakers, panels, fixtures) with current supplier pricing. Estimate labor hours by task type—rough-in typically takes 4-6 hours per room, panel work 4-8 hours depending on size, and trim-out 2-3 hours per room. Apply appropriate hourly rates for journeymen ($50-85/hour) and apprentices ($30-50/hour). Include permit fees ($50-300), inspection costs, and travel time. Add material markup (25-40%) and ensure labor rates cover overhead and profit. Most residential projects range $85-150 per hour all-in, while commercial rates run $95-175 per hour.

Question 2

What is the rule of thumb for electrical estimating?

Accepted Answer

A common rule of thumb is $3-8 per square foot for basic residential wiring, though this varies significantly by region and project complexity. For commercial work, figure $4-10 per square foot. Another useful rule: multiply your material cost by 3-4x to cover labor, overhead, and profit. For labor hours, estimate 1-1.5 hours per circuit for residential rough-in, plus additional time for panel work and trim-out. Always add 10-15% contingency for unforeseen issues and site conditions. These rules provide quick ballpark figures, but detailed estimates based on actual measurements and current costs are essential for accurate bidding.

Question 3

What should be included in an electrical estimate?

Accepted Answer

Include all materials itemized by type (wire, conduit, boxes, breakers, panels, fixtures), labor hours broken down by task (rough-in, panel work, trim-out, testing), permit and inspection fees, equipment rentals if needed, travel time for job site location, testing and certification costs, and warranty information. Clearly state what's included and excluded in scope. List any assumptions about site conditions or access.

Question 4

How much should I charge for electrical work?

Accepted Answer

Residential electricians typically charge $50-100 per hour for labor, with total project rates of $85-150 per hour including materials and overhead. Commercial work runs higher at $75-150 per hour for labor. Material markup is usually 25-40% above wholesale cost. Service calls often include a trip charge of $75-150 plus hourly rates.

Question 5

How do you estimate wire and material needs?

Accepted Answer

Measure actual distances for wire runs, then add 20% for routing around obstacles, connections, and waste. For conduit, measure straight-line distances and add footage for bends and fittings. Count all boxes, switches, and outlets from plans. Include one breaker per circuit plus spares (typically 20% extra panel capacity). Use an electrician estimate template with a built-in material list to ensure nothing gets missed.

Question 6

How much does electrical house wiring cost to estimate?

Accepted Answer

An electrical house wiring estimate typically ranges from $3,000-$15,000 for a full home rewire, depending on square footage and complexity. For new construction, expect $3-8 per square foot. A 1,500 sq ft home averages $8,000-$15,000 for complete rewiring, while a 2,500 sq ft home runs $12,000-$20,000. Factors affecting your electrical house wiring estimate include number of circuits needed, panel size (100-200 amp), accessibility of walls and attic, local permit fees, and whether existing wiring needs removal.
