Different Types of Residential Electrical Estimating Methods
Let’s take our way toward the focused topic of this blog!
Here, we discuss the different types of residential electrical estimating methods.
-
Per-point Cost Estimation
You must calculate your project budget using this method if you deal with small or simple electrical works. Consider the fixed rates of each component or the phase involved in this project.
Simply put, factor in the exact quantities of electrical outlets, fixtures, and other resources. The detailed listing can help you determine the project’s total budget easily.
-
Labor Unit Cost Estimation
As the name shows, the method is directly linked with the labor cost estimation. The formula to calculate this cost is:
Labor Cost Estimate = Hourly labor rate x No. of hours
It is an approach that helps contractors identify the complexity of subtasks and hire labor accordingly.
-
Pre-build Cost Estimation
Pre means doing something before implementing the task in the real world. Right? So, the pre-build cost estimation method gives a comprehensive proposal or residential electrical estimates before construction starts.
In this method, you determine the needs of projects after measuring the area in square footage. With this method, you can ensure that your estimates will be 100% accurate if other things go right.
-
Design & Construct Cost Estimation
The method provides a single table where designers and constructors sit around. They work together to design and construct an electrical product according to the client’s requirements.
Estimators use this method rarely, where designs and construction influence each other significantly. It mostly happens in the case of complex residential electrical works.
-
Electrical Guesstimate
Electrical guesstimate is the last and the least formal method when we discuss how to estimate electrical work. It is applicable when a contractor deals with simple or informal electrical works.
The estimates that come out are the results of the rough idea you can make by leveraging the industry experience.

Difference Between Estimates and Guesstimates
You are unable to hit 100% accuracy in electrical estimates with guesstimating, whether you have 30 years of estimating experience or more. Undoubtedly, you can win the project, but with compromising on your profit margin. In some cases, you can even lose the project due to the high compatibility of your competitors.
Inversely, accurate estimates go oppositely; higher profit margins and 99.9% bid win chances. If you make 5% or less profit, you can bring it between 8-15% or more with professional estimates.
Simply put, estimates are better than guesstimates regarding all terms and concerns.
