The formula
Cost = windows x (unit price x frame multiplier x glass multiplier) + install type + permit
Insert replacements reuse the existing frame and are cheapest. Full-frame replacement removes the frame down to the studs and adds roughly 25–40% per opening.
Frequently asked questions
How much does it cost to replace a window?
Most standard replacement windows run $450 to $1,200 installed per opening in 2026. Large, custom-shaped or impact-rated units cost considerably more.
Is full-frame or insert replacement better?
Insert replacement is cheaper and faster when the existing frame is sound. If there is rot, water intrusion or you want a larger glass area, full-frame is the right call.
