Data Sources & Methodology
Data last updated: January 2025 · Updated annually
How the Numbers Work
Job cost estimates start with Remodeling Magazine's midpoint costs for each project type. Regional adjustments apply RSMeans city cost index multipliers, which account for local labor rates and material costs. Costs are expressed in ranges (low/mid/high) reflecting different finish levels.
Data Sources
Remodeling Magazine Cost vs. Value Report
Annual survey of remodeling contractors covering costs and resale value for 22 common projects in 150+ markets. The industry benchmark for remodeling costs.
RSMeans Construction Cost Data
Labor and materials cost data by region used for regional cost multipliers. Industry standard for construction cost estimation.
U.S. Census Bureau American Housing Survey
National survey of housing conditions and improvement spending. Used to validate aggregate cost estimates.
NAHB Remodeling Cost Research

Limitations
Cost vs. Value survey reflects reported contractor costs, not bids. High-end finishes, custom work, and structural complications add costs that averages can't predict. Permit costs are not included and vary by jurisdiction. What you find inside walls when demo starts changes the budget. Labor cost inflation has run above general inflation since 2022.
About Estimates
The numbers on this site are estimates built from published data. They're a starting point for budgeting and comparison, not a quote. Your actual cost depends on specifics no calculator can know: your vendor, your timing, your circumstances.
Nothing on this site is financial, legal, or professional advice. If the decision is significant, talk to a professional.
