Window cost is mostly the units themselves — vinyl is cheapest, wood and fiberglass cost more, and bay or custom-shaped windows run highest — plus a fairly steady installation charge per opening. Whole-home projects get a slight per-window discount from crews working at scale.
How it’s calculated & sources
Total = number of windows × (unit price + installation). Defaults reflect typical installed mid-grade pricing; adjust the per-window figures to match local quotes.
Benchmark: replacement windows average roughly $450–800 each installed, with specialty units higher (HomeAdvisor / Angi, 2025).

Frequently asked questions
Do new windows pay for themselves?
They cut energy bills and boost comfort and resale appeal, but full payback on energy savings alone can take many years. Comfort and noise are often the bigger wins.
Vinyl or wood?
Vinyl is low-maintenance and affordable; wood and fiberglass look premium and insulate well but cost more. Match the choice to your home and budget.
