What will replacing your windows cost?
Enter how many windows, the style, and the frame and glass you want for an itemized estimate built from current 2026 rates — total and per window.
What drives window replacement cost
These factors move a window quote the most.
Frame material
Vinyl is the budget standard; fiberglass and wood cost more but offer better looks and performance; aluminum sits in between.
Glass package
Triple-pane and premium low-E coatings improve efficiency and noise reduction but add to the per-window price.
Style
Double-hung and sliders are the most affordable; casements cost a bit more; bay and bow windows are far pricier.
Install type
A simple insert into the existing frame costs less than a full-frame replacement that opens the wall to the rough opening.
Window cost by style (installed, per window)
Typical 2026 installed cost ranges for a standard vinyl, double-pane window.

Window replacement questions, answered
How much does window replacement cost in 2026?
Most replacement windows run about $400 to $1,200 each installed for standard styles, so a typical 10-window project lands around $5,000 to $12,000. Bay and bow windows cost considerably more.
What makes a window more expensive?
Frame material (wood and fiberglass cost more than vinyl), glass package (triple-pane and premium low-E), window style, and whether it is a simple insert or a full-frame replacement.
Insert vs full-frame replacement — what's the difference?
An insert fits a new window into the existing frame and is cheaper. A full-frame replacement removes everything down to the rough opening and costs more but fixes rot and lets you resize.
Are new windows worth it for energy savings?
Energy-efficient windows reduce heating and cooling loss and can qualify for tax credits or rebates, though the payback period varies by climate and how old the existing windows are.
How accurate is this estimate?
It is a planning estimate from current installed-cost ranges. Custom sizes, hard-to-reach openings, and trim work can change the price, so get local quotes before budgeting.
