Electrical Cost Calculator: Free estimate online
Are you planning a new construction or electrical upgrade? Our powerful Electrical Cost Calculator helps homeowners in Texas (and beyond) estimate their project budgets with ease. Whether you’re wiring a new home or rewiring an old one, understanding the real costs involved is essential. This blog post explains how the calculator works, how to use it step by step, and what cost factors are considered.
How to Calculate Electrical Cost Estimate Step by Step Process
Using the calculator is simple and accurate. Follow these steps:
Step 1: Choose Your Project Type
Select whether you’re estimating a new construction or an upgrade/rewire project.
Step 2: Enter Square Footage
Input the total area of your home or the space being wired. The tool uses this to scale labor and materials.
Step 3: Adjust the Location Factor
Apply a multiplier (default 1.00) to account for special site conditions like waterfront or hillside properties.
Step 4: Customize Rates and Fees
You can edit:
- Labor rate (US$/hr)
- Material cost per square foot
- Permit fees (based on your city)
Step 5: Add Device Details
Type in the number of devices (outlets, lights, switches) and cost per device. The calculator factors this into the budget.
Step 6: Toggle Optional Add-ons
If you plan to install EV charging, smart wiring, or surge protection, select these checkboxes to add their cost.
Step 7: Review Waste and Contingency Settings
Waste and contingency percentages help make your estimate realistic. You can customize these or leave the defaults.
Step 8: Click “Calculate Estimate”
Your cost range appears instantly, including a low-end and high-end estimate for planning flexibility.

Main Cost Factors in Our Electrical Calculator
Our tool breaks down your estimate into key pricing categories:
1. Project Type (New vs Upgrade/Rewire)
- New Construction involves fewer labor hours and lower complexity.
- Upgrades/Rewires are more intensive due to demolition, patching, and older wiring.
2. Square Footage & Scope
- The calculator uses your home’s square footage to estimate both labor hours and material quantity required.
3. Location-Based Price Adjustments
- Geo-pricing: Hillside, waterfront, or remote properties incur higher labor costs.
- Multiplier lets you apply localized cost adjustments for Texas or other areas.
4. Labor Rate (US$/hr)
- Default set to Texas average of $32/hr, but you can customize it based on your contractor’s quote.
5. Material Cost per Square Foot
- Covers wiring, boxes, conduits, and basic devices. Upgrade projects may raise this rate.
6. Permit Fees
- Include local inspection and permitting costs, editable by user (default is $200).
7. Device Count and Cost
- Input how many outlets, switches, or fixtures you’re adding. You can adjust the per-device installation cost too.
8. Optional Features
- EV Charger Circuit (+$1200)
- Smart Home Wiring (+$800)
- Whole-House Surge Protection (+$500)
9. Waste & Contingency
