Planning calculation
Enter locally researched assumptions to see a range.
What belongs in a real replacement-cost estimate
- Finished area, foundation, number of stories, attached structures, and roof shape
- Exterior wall, roofing, flooring, cabinetry, countertop, window, and interior-finish quality
- Heating, cooling, plumbing, electrical, fireplaces, built-ins, and specialty features
- Local labor and material costs, contractor overhead, debris removal, and site access
- Building-code upgrades, demolition, architectural work, permits, and demand surge
A square-foot calculation is only a reasonableness check. Ask each insurer what property data and cost database produced its estimate, then correct inaccurate inputs.
Why two estimates can differ
Estimators may use different cost databases, quality grades, code assumptions, inflation factors, and treatment of garages or finished basements. A lower estimate is not automatically more accurate. Compare the inputs line by line, not just the final number.
