Material Cost = Sum of the cost of all materials
- Labor Costs: This includes the cost of all labor required for the addition, such as carpenters, electricians, plumbers, etc.
Labor Cost = Sum of the cost of all labor
- Permit Costs: This includes the cost of all permits required for the addition.

Utility Cost = Sum of the cost of all utilities
- Contractor Overhead and Profit: This is the amount the contractor charges for their overhead and profit. It is usually a percentage of the total cost of the project.
Contractor Overhead and Profit = (Material Cost + Labor Cost + Permit Cost + Utility Cost) × Contractor's Percentage
- Contingency: This is an amount set aside for any unexpected costs arising during the project. It is usually a percentage of the total cost of the project.
Contingency = (Material Cost + Labor Cost + Permit Cost + Utility Cost + Contractor Overhead and Profit) × Contingency Percentage
Total Cost of Home Addition: This is the total cost of the home addition, including all of the above factors.
Total Cost = Material Cost + Labor Cost + Permit Cost + Utility Cost + Contractor Overhead and Profit + Contingency
Let's say you plan to add a new bedroom to your home. Here is how you would calculate the cost:
- Material Costs: Let's say the materials for the bedroom addition (lumber, drywall, flooring, fixtures, etc.) will cost $20,000.
- Labor Costs: Let's say the labor for the bedroom addition (carpenters, electricians, plumbers, etc.) will cost $15,000.
- Permit Costs: Let's say the permits for the bedroom addition will cost $1,000.
- Utility Costs: Let's say adding the new utilities (plumbing, electrical, HVAC) for the bedroom addition will cost $5,000.
- Contractor Overhead and Profit: Let's say the contractor charges 20% for overhead and profit.
Contractor Overhead and Profit = ($20,000 + $15,000 + $1,000 + $5,000) * 20% = $8,200
- Contingency: Let's say you set aside a 10% contingency for any unexpected costs.
Contingency = ($20,000 + $15,000 + $1,000 + $5,000 + $8,200) * 10% = $4,920
- Total Cost of Home Addition:
Total Cost = $20,000 (Material Cost) + $15,000 (Labor Cost) + $1,000 (Permit Cost) + $5,000 (Utility Cost) + $8,200 (Contractor Overhead and Profit) + $4,920 (Contingency) = $54,120
