Custom Home Build Calculator

How It Works

Choose your home size, finish level (from standard to luxury), number of stories, and garage size. The calculator applies per-square-foot construction costs, a multi-story premium, plus site work, permits, and a 10% contingency to estimate your total build cost.

Custom Home Tips

• Land cost is not included - budget 20-30% of total project for the lot
• Multi-story homes cost ~5% more per floor due to structural requirements
• Energy-efficient building adds 2-5% upfront but saves significantly long-term
• Lock in material prices early - lumber and steel fluctuate seasonally

About This Tool

This custom home cost estimator provides ballpark figures based on national average construction costs per square foot. Actual costs vary dramatically by region, builder, material choices, and site conditions. Use this for initial budgeting before engaging with builders for detailed estimates.
