Basedon our observations, two terms that people often mix up are quotes and estimates. While the terms are related, they do refer to two different concepts. The one you use depends on how you want to operate your electrical business.

A material takeoff is an important part of the estimating process for many construction projects. It serves as a sort of electrical material pricing guide. By using the blueprints for the house, you can build a list of materials necessary to complete the job. This list is referred to as a material takeoff list and helps you provide a detailed breakdown of costs. Typical materials in your materials takeoff list include:

Our research indicates that the median pay of an electrician is $27.36 per hour, so you will likely pay your employees a wage similar to this amount. To get your overall hourly rate, figure out how many workers it takes to complete a job, then add up each of their hourly pay rates to get your total hourly labor rate. Then, multiply your hourly labor rate by the number of hours you estimate the job will take.

Now that you understand the scope of the job and know how much material and labor you will need to complete it, you have everything you need to figure out how to estimate electrical work for that project.

As using high-quality materials is essential, make sure you include each of your materials as a line item in your electrical job estimate template. After putting it to the test, estimating using a template standardizes the process, which lets you complete your estimates faster for each new customer.

The last element to add to your estimate is a markup for profit. Based on our observations, this markup depends on the average prices for electrical work in your area, and how much profit you want to make off of each job.

Before handing over the estimate to your customer, make sure that you double-check that all of the information is correct and that nothing has changed since you started the process. Review the following information:

If necessary, you can redo some of the calculations to ensure that the final total you present to your customer is correct. Providing a warranty or guarantee is also useful in reassuring your customer about your service. Lastly, creating a timeline for approval gives both parties peace of mind and ensures you have an answer within a reasonable timeframe.

The per-point method is often used for smaller or simpler projects. It means you factor in a fixed price for each point in the electrical system (e.g., pricing considers the number of electrical fixtures and outlets). This makes it easy to calculate the total cost as you itemize your list and account for each point.

Pre-build is detailed in a written estimate or proposal before the actual construction begins. It means you need to investigate how the project is based on the square footage of the area and the resources needed, leading to more accurate budgeting.

This method combines both the design and construction teams as a single point of contact for the client. It is effective for complex projects where the design influences the electrical work significantly.

Guesstimation is the least formal way when addressing how to estimate electrical work. Contractors typically use it for very small or informal jobs. Guesstimation is based on your experience and intuition for a quick idea of the cost.

Your pre-bid planning and review stage is where you begin planning the scope of electrical work. You may need to consult with the customer to evaluate how the job accounts for potential challenges or obstacles, as well as what factors in the type of electrical systems involved.

Material takeoff involves listing all the materials required for the project. This step puts together a list of all necessary components so that the final estimate is transparent with itemized costs for clarity.

Remember that your estimate takes into consideration any warranties or guarantees offered by yourself or the manufacturer. Ensure any warranty or guarantee included is updated regularly to match market trends and industry standards.

The material cost in commercial projects varies greatly. Figuring out how to estimate electrical work for supplies requires an understanding of how your geographic location weighs the current market rates for electrical components.

As a commercial project usually includes potential additional expenses for unforeseen issues and is impacted by any required permits or inspections, these hurdles often extend the time and duration of the project and require additional hours from your electricians.

The final step when understanding how to estimate electrical work is to compile your costs. Your final amount includes a markup for profit and overhead. Your overhead includes labor and material costs, as well as all the less obvious costs associated with the project. Then, determine your profit margin by taking a percentage of that total cost you determine.

Knowing how to estimate electrical work is only the first step of the job. Once you know how to estimate, you need to understand how to present it to your customer in a clear and easy-to-understand way.

No matter what method you choose, you should never create an estimate from scratch for each new job. With this approach, you end up doing a lot of manual and time-consuming work and waste time that you could otherwise use to bring in more revenue.

Make sure your point system is based on previous similar projects for accuracy and is validated by cross-referencing with other estimates or quotes from local market rates. You should ensure that it is updated regularly to match industry standards as prices can change over time due to economic factors (e.g., inflation, material costs).

Building a good relationship with your customers is key to winning their repeat business and getting referrals. Over time, we found that customer consultation and communication before starting a job is a good way to better understand your customer preferences and budget.

The second is assemblies estimating, which involves estimating the cost of an assembled product, including all its smaller parts. A good example is installing a new electrical panel. An assemblies estimate looks at the potential cost of each finished panel, rather than all of its components.

You should send your estimate or quote as soon as you have all the information needed to give one accurately. Knowing how to estimate electrical work quickly so you can get back to your customer first is often a deciding factor for whether they choose you or a competitor for the job.

To calculate the price of electrical work, multiply your hourly labor rate by the number of hours the job will take to complete. If any extra materials are required for the job, be sure to add that to the total cost.

Take, for example, the task of installing a light fixture. Assessing this type of work is wildly different in terms of costs and labor when compared to evaluating existing wiring and electrical systems, for example.

You may sometimes have to deal with difficult-to-reach spots or even remove drywall in some areas, which means you also have to charge your customer the cost of drywall installation and maybe even paint costs. Both of which you should include in your estimate.

This document discusses the estimation and costing of domestic and industrial wiring. It covers types of wiring, factors to consider in wiring selection, importance of layout planning, sub-circuiting, standard wire sizes, looping, testing procedures before commissioning, and processes for estimating costs of domestic and industrial wiring projects. Key steps for domestic wiring estimation include drawing layout plans, calculating electrical loads, determining circuits and sub-circuits, selecting wires and accessories, and calculating material and labor costs.Read less

If your electrical panel needs replacing, you might need to add a new panel to the total cost to rewire your home. Electrical panel replacement costs fall between $400 and $2,500. Most homeowners will pay somewhere in the middle of this price range for a 200-amp panel.

If you need to open walls to run wires through your home, the cost to knock down walls falls between $0.40 and $6.40 per square foot. Load-bearing and stone walls cost the most to open, as they require more skill and costly replacement materials, while drywall is a fast and simpler material to open and replace.

Wiring a new house may be cheaper than rewiring an old house. Newer homes typically have easier layouts for accessing wires and installing new ones into the wall. Additionally, older homes can come with many hidden surprises, as building regulations have changed over the decades to make it easier for electricians to access the walls.

As one of the more affordable types of wiring for a home, THHN or THWN wire costs between $0.15 and $1.50 per foot on average. Also called thermoplastic, high heat-resistant nylon-coated (THHN) wire and thermoplastic, heat-resistant, water-resistant nylon (THWN) wire, these materials contain a single conductor, insulation and a jacket to protect the wires. Their affordability makes thempopular in many homes.

Your safest option is to hire a licensed electrician to rewire your house instead. An electrician near you has the experience to safely complete the job.
