Total Window Cost
Window Replacement Cost depends on the number of windows, size, glass type, and installation method.
Total Cost = Number × (Window Cost + Installation Cost)
Window type costs (per window, standard size):
- Single pane: $150–300 — basic, poor insulation
- Double pane: $350–700 — most common, good insulation
- Triple pane: $550–1,100 — premium insulation, best energy savings
Size impacts cost:
- Small (24"×36"): 0.7× base cost
- Standard (30"×48"): 1.0× base cost
- Large (36"×60"): 1.4× base cost
Installation costs:
- Retrofit (insert): $100–200 per window
- Full-frame replacement: $200–400 per window
Energy savings from upgrading:
- Single → Double pane: $125–465/year savings
- Double → Triple pane: $50–150/year additional savings
- Low-E coating adds $25–50 per window but saves 30–50% on heat gain
