How this calculator prices your project
- Starting price: a standard vinyl double-hung window, installed — $325 / $800 / $1,275 (low / typical / premium), aggregated from the state price data behind our state pages. Choosing a state swaps in that state's prices.
- Window type, frame material and glass each apply a multiplier: the midpoint of the published installed range for that option divided by the midpoint for the baseline option (double-hung, vinyl, double-pane).
- Labor is about 31% of an installed window price (HomeGuide: $100–500 labor on a $350–1,000 window). Upper-floor windows add 15% to their labor share.
- Totals are the sum of each line. They exclude trim/siding repair, rot or framing repair, and permits where required.

Frequently asked questions
How much does it cost to replace one window?
About $325–$1,275 installed for a standard vinyl double-hung window, with most quotes near $800. Picture and single-hung windows cost less; casement, bay and bow windows cost more.
How much does it cost to replace 10 windows?
Ten standard vinyl double-hung windows cost about $3,250–$12,750 as insert replacements (typical $8,000). Full-frame replacement of the same ten windows is roughly $4,550–$17,850.
How much does a bay window replacement cost?
A vinyl bay window runs about $913–$3,583 installed in this calculator, versus $800 typical for a double-hung window. Bow windows cost more again because they use four or more panels.
Are wood windows worth the extra cost?
Wood frames are the most expensive option — a wood double-hung window is about $881–$3,455 installed versus $325–$1,275 for vinyl. Fiberglass and composite sit between the two and need less maintenance than wood.
What is the difference between insert and full-frame window replacement?
An insert (pocket) replacement fits a new window into the existing frame and is the cheaper option when the frame is sound and the size stays the same. Full-frame replacement removes the old frame down to the rough opening — needed for rot, size changes or a style change — and costs noticeably more in labor.
Is labor included in these window prices?
Yes. Every figure is installed cost. Labor is typically about 31% of the total, and the bar under the estimate shows the split for your project.
