How We Calculate Construction Costs

Four factors drive every estimate — here's the logic behind the numbers.

📐

Square Footage Base

We start with cost-per-square-foot benchmarks from RS Means and industry surveys, adjusted for project type.

🏆

Quality Multiplier

Budget, standard, and premium tiers reflect real differences in materials and finishes — typically a 30-60% cost spread.

🗺️

Regional Adjustment

Labor and material costs vary 40-60% between high-cost metros and rural markets. Our regional factors reflect this.

📊

Category Breakdown

We split costs across 5 categories (structure, exterior, MEP, interiors, site) using typical industry cost distribution percentages.
