How this estimate is calculated

We start from published national average costs per square foot for each project type, then adjust for the finish quality you select and a regional cost index for your state, since labor and material prices vary widely across the country.

The materials and labor split covers the direct cost of building the project. Permits and fees is a placeholder for local inspection and permitting costs, which vary by municipality. Contractor overhead and profit reflects the margin a licensed general contractor typically adds to run the job. Contingency covers the unexpected costs that come up once work begins, such as hidden damage or supply changes.

This is a planning estimate, not a quote. Get itemized bids from licensed, verified contractors before you commit to a budget.
