Window Replacement Cost Calculator

Estimate replacement-window cost by count, style, material, install type, and state.

Your windows
Count all windows you plan to replace. The average US home has 10-15 windows. Bulk orders of 5+ windows typically qualify for 15-30% contractor discounts.
Double-hung ($300-$1,000) is most common. Casement ($400-$1,200) provides better air sealing. Bay ($1,500-$5,000) and bow ($1,800-$6,500) cost 3-8x more due to multi-panel construction.
Vinyl ($350-$900) is the best value for most homes with zero maintenance. Fiberglass ($400-$1,500) lasts 30-40 years. Wood ($600-$2,000) looks best but requires regular upkeep.
Double-pane is the standard - 80% of homeowners choose it. Triple-pane provides the best insulation for cold climates but costs 40-60% more. Single-pane is outdated and wastes energy.
Location & options
Northeast and West Coast states pay 10-25% more than national average. California averages $1,129/window vs. $925 in Arkansas based on Modernize data from 1M+ projects.
Low-emissivity coating reflects heat while letting light through. Reduces energy bills by blocking UV and infrared rays. Pays for itself in energy savings within 2-3 years in most climates.
