How To Calculate Whole-House Rewiring Cost With This Calculator Full Instructions

Step 1: Enter Your Home Size

Square footage is the foundation of the calculator. Larger homes require:
  • More electrical wiring
  • More circuits
  • More labor
  • More outlets and switches
  • More inspection requirements
The calculator multiplies your home’s square footage by the selected rewiring rate to generate the base project cost.
Example
1,800 sq. ft. home × $14 per sq. ft. Base Rewiring Cost = $25,200

Step 2: Select the Rewiring Scope

Not every rewiring project involves the same amount of work.
Partial Rewire
Suitable when only certain rooms or sections require upgrades.
Standard Whole-House Rewire
Most common option for older homes requiring complete wiring replacement.
Full Rewire With Circuit Upgrades
Includes extensive electrical modernization, additional circuits, and capacity improvements. Homes requiring more circuits and electrical capacity generally cost more to rewire.

Step 3: Choose Wall and Access Difficulty

Access is one of the biggest factors affecting whole-house rewiring costs.
Open Walls During Remodel
Lowest labor cost because electricians can easily access framing.
Finished Walls With Attic or Crawlspace Access
Moderate cost because wires must be pulled through existing spaces.
Difficult Access or Older Construction
Higher cost due to limited access, plaster walls, fire blocking, and structural obstacles. The more difficult it is to reach existing wiring, the higher the labor cost.

Step 4: Evaluate Electrical Panel Condition

Many rewiring projects uncover electrical panels that no longer meet modern demands. The calculator includes:
Existing Panel Remains
No additional panel cost.
Panel Upgrade Needed
Common when older homes have limited capacity.
Service Upgrade and New Panel
Often necessary when increasing electrical demand significantly. Modern appliances, EV chargers, and HVAC systems frequently require panel upgrades during rewiring projects.

Step 5: Account for Outlets, Switches, and Fixtures

A complete rewire often includes replacing electrical devices throughout the home. This may include:
  • Standard outlets
  • GFCI outlets
  • AFCI protection
  • Light switches
  • Smart switches
  • Fixture boxes
  • Lighting connections
Homes with more devices generally require more labor and materials.

Step 6: Add Drywall and Finish Repairs

After wires are installed, walls and ceilings often require repairs. Common repair items include:
  • Drywall patching
  • Texture matching
  • Paint touch-ups
  • Ceiling repairs
  • Access hole restoration
The calculator includes repair allowances because these costs are often overlooked during budgeting.

Step 7: Include Permit and Inspection Costs

Whole-house rewiring projects typically require permits and inspections. Permit requirements help ensure:
  • Electrical safety
  • Code compliance
  • Proper grounding
  • Correct circuit protection
  • Safe installation practices
Permit fees vary depending on project scope and local requirements.
