How to Estimate Electrical Work

To estimate electrical work, break down all materials, labor, permits, and inspections. Include contingency and profit margins, then present a clear, itemized estimate to your client. Accurate estimates help prevent underpricing, manage expectations, and ensure projects remain profitable. Using tools like DepositFix can simplify this process by generating professional estimates quickly.

Review the Project Scope

Before you start estimating, thoroughly understand the project’s requirements.

• Examine electrical plans or blueprints.
• Identify the type of work: new installation, repair, or upgrade.
• Note special requirements such as code compliance, permits, or high-voltage systems.

Example: For a residential rewiring project, determine how many circuits, outlets, and switches are needed.

Calculate Material Costs

List all materials required and assign costs to each.

• Cables, conduits, outlets, switches, panels, breakers, and connectors.
• Include additional items like junction boxes, lighting fixtures, and grounding materials.
• Factor in waste (usually 5–10%).

Estimate Labor Costs

Calculate the time and labor cost to complete the project.

• Break down tasks: wiring, installation, testing, and inspection.
• Assign hourly rates to electricians and helpers.
• Include overtime if applicable.

Example:

• Electrician: 20 hours × $50/hr = $1,000
• Helper: 15 hours × $25/hr = $375
• Total Labor: $1,375

Factor in Permits and Inspections

Electrical projects often require permits and inspections.

• Research local permit fees.
• Include inspection costs in the estimate.
• Schedule time for inspections into your labor estimate.

Example: Permit fee: $150

Add Contingency and Profit Margin

Include a contingency (5–10%) for unexpected issues and your desired profit margin.

• Contingency: $200
• Profit margin: 15% of total cost

Final Estimate:
Materials: $335
Labor: $1,375
Permits: $150
Contingency: $200
Subtotal: $2,060
Profit (15%): $309
otal Estimate: $2,369

Present the Estimate to the Client

Provide a professional, clear estimate that includes:

• Itemized materials and labor
• Permit and inspection fees
• Contingency and total price
• Payment terms and timelines

Tip: Use a clean format with tables for clarity. Clients appreciate transparency.
