Why estimates are so important
Estimates are a vital part of any trade work from auto repair to construction. Residential electrical work, of course, is no exception. And since an electrical work residential estimate is often a customer’s first impression of your business, you never want to mess up your first impression. You may need to provide an estimate for electrical work to:
- A homeowner.
- An organization for a bidding process.
- A general contractor.
Some of the benefits of knowing how to estimate residential electrical work include:
- A better understanding of the project scope.
- Knowledge of the materials and labor needed to complete residential electrical work.
- The ability to create a realistic budget.
- Turning a profit on every job.
Although the prices you outline in your estimate can be subject to change, it reflects badly on your business if the project’s final cost is a lot more than your original estimate. As a result, it’s essential to present your customer with an estimate and not a quote.
The difference between a quote and an estimate
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 quote is an exact price that your customer will pay for your services. When you give your customer a quote, you’re contractually obligated to fulfill the services at that given price. Quotes give customers peace of mind, and if you estimate the costs right, you shouldn’t worry either. However, the exact science of how to quote electrical work is more difficult than providing an estimate. On the other hand, estimates are not contractually binding and offer room for variation once the project is underway. However, once again, you don’t want the final price to deviate too far from the estimate. Make sure that your customer has a clear understanding of whether you’re giving them a quote or estimate before you start any of the work. Let’s talk about how you go about creating estimates and how to price residential electrical work.
Estimate electrical wiring for a house: The basics

Whether you’re providing an estimate to a homeowner or you’re participating as part of a bidding process to wire a set of new builds, chances are residential electrical work will be the bulk of your sales. Therefore, knowing how to estimate residential electrical work is an essential part of your business.
Knowing how to estimate electrical wiring for a house can be a long process, but it’s important to spend time ensuring accuracy before starting any electrical work. Making an error in the middle of the job can end up costing you more time and money.
Here are some steps to follow to accurately estimate electrical work for your customers.
Step 1: Choose the right jobs
Even though your goal is to bring as much revenue to your business as possible, you should not say yes to every electrical job that comes your way. Instead, you should be honest with yourself and your customers and not take any jobs in which you have limited experience or would be unable to estimate the costs accurately. Stick to jobs within your scope and that you’re confident in until you acquire more expertise. Take the time to evaluate the needs of each job, and if you’re unable to complete it in good faith, let your customer know.
Step 2: Confirm the specifications
If you’re participating in a bidding process, be sure to review the specifications in the request for proposal (RFP). RFPs often use complicated language that can be difficult to break down, but understanding the specifications of the RFP can make the difference between moving on to the next round of the process and instant disqualification. To ensure the success of your RFP, make sure to fully understand the current electrical wiring of the house that you’ll be working on. If you notice anything out of the ordinary or a potential oversight, it’s key to highlight this in your proposal.
Step 3: Review the drawings
There will often be drawings, blueprints, and graphics that come with the RFP in a bidding process. These visual representations are important as they give you the full scope of the job. If you’re dealing with a homeowner, ask if they still have the blueprint of their home. If not, you will have to perform a walkthrough to get an idea of what needs to be done. Even though you’re doing electrical work, you should still check out all of the architectural drawings you’re given. There are many other components of a house that may become obstacles to your work, such as the:
Reviewing these drawings is necessary to complete a material takeoff.
Step 4: Perform a material takeoff
Material takeoffs are an important part of the estimating process for many construction projects and serve 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 allows you to create a breakdown of material costs. Typical materials in your materials takeoff list include:
- Circuit breakers.
- The number of switches and outlets.
- Electrical roof conduits.
Your list also allows you to calculate material costs, which should be broken down in your estimate.
Step 5: Calculate labor costs
Once you know what kind of work will be involved, it’s time to calculate your labor costs. The simplest way to charge for residential electrical work is by the hour, making it easy to calculate labor costs. According to the Bureau of Labor Statistics, 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. Next, multiply your hourly labor rate by the number of hours you estimate the job will take.
Hourly labor rate x number of hours = total labor rate
The above formula will give you an accurate view of labor costs for your estimate and can serve as the basis for your electrical work pricing guide.
Step 6: Create your estimate
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 create your electrical estimate for residential. Make sure you include each of your materials as a line item in your electrical job estimate template. Using a template for this gives you a standard process, which lets you complete your estimates faster for each new customer.
Step 7: Add overhead and profit
When you calculate your labor and materials costs, you only calculate how much the job will cost you. With these numbers alone, you are not making any profit from the job. In fact, you’ll be losing money because you aren’t covering your overall expenses, such as transportation and insurance requirements. This is why you have to factor overhead costs into your estimate — to cover all the costs to operate your business. Overhead is usually 13 – 20% of your total sales cost, depending on your business expenses. The last element to add to your estimate is a markup for profit. This markup depends on the average prices for electrical work in your area, as well as how much profit you want to make off of each job.
Step 8: Build your proposal
You’ll most likely have to present your estimate as part of an overall proposal for a bidding process. Before submitting your final proposal, review all of the requirements one more time to ensure that there isn’t anything that would make you non-compliant.
Step 9: Double-check your numbers
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:
- Customer’s name and address.
- List of materials and costs.
- Labor hours and costs.
- Final total.
If necessary, you can redo some of the calculations to ensure that the final total you present to your customer is correct.
How should I create an estimate or quote?
Knowing how to estimate residential 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.
Whether you decide to present an estimate or a quote, the process is similar, and you want to ensure accuracy. That being said, you want to create an estimate to in case of disagreements or unforeseen changes.
When it comes to creating your estimate, you have several options:
- Use Google Sheets or Excel to create an estimate.
- Download an estimate template online.
- Use electrical estimate software like Method.
No matter what method you choose, you shouldn’t 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 could be used to bring in more revenue.
A better method is to have an estimate template on hand to save you time and ensure that your estimates stay consistent.
How much detail does an electrical estimate need?
As a rule of thumb, you should include as much detail in your residential electrical work estimates as possible.Here’s what customers expect to see on an electrical estimate:
- Their name and address.
- Description of the work.
- The name of your business and contact information.
- A detailed breakdown of the work.
- The total price.
The breakdown of the work should involve labor, materials, and any additional costs so that your customer can better understand the final price.
Make sure you specify whether the total price includes taxes or not.

How you estimate electrical wiring depends on if the house is a new build or if you’re rewiring an older home.
Electrical wiring for a new build is considerably easier than rewiring an older home. This is because the wiring goes in before the walls, requiring less time and labor. For these jobs, you only have to estimate the labor needed to install the wiring.
For an older home, you have to first remove the current electrical wires to replace them with new wires, which requires more labor and more tools.
There are several other additional factors you might have to deal with while rewiring a home.
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.
