Window Replacement Cost
What This Calculator Does
The Window Replacement Cost Calculator estimates the cost of replacing windows in your home based on the number of windows, window type, and 2026 US national average pricing. Enter the number of windows and select the type and material to get a total cost estimate.
Window replacement is one of the highest-ROI home improvements, improving energy efficiency, curb appeal, and home value. ENERGY STAR certified windows save homeowners $100-$600 per year on heating and cooling costs compared to single-pane older windows.
How to Use
- Count the number of windows being replaced and note their types (single-hung, double-hung, casement, picture, bay/bow).
- Count sliding glass doors separately - they cost 2-3 times more per unit.
- Select the frame material - vinyl, wood, aluminum, or fiberglass.
- Click "Calculate" to see the total cost estimate for windows and installation.
- Add $100-$300 per window for old window removal and disposal.
