Window Replacement Cost Calculator

A standard replacement window runs about $300 to $800 installed for vinyl, the most common choice. Fiberglass runs $600 to $1,500, wood $800 to $1,800, and a bay or bow window $1,500 to $4,500 because it is a larger, framed-out opening. The calculator above prices a whole job by the number of windows and the frame type. Custom sizes, glass upgrades, and any frame or trim repair move the number.

A typical home has 8 to 12 windows. At the vinyl rate that is roughly $3,000 to $8,000 for the house; fiberglass or wood pushes it higher, and a home with a bay window or many oversized openings higher still. Ordering the whole house at once usually earns a better per-window price than replacing them a few at a time. Set the count and type in the calculator for your own number.

An insert, or pocket, replacement sets a new window inside the existing frame, which is faster and cheaper and works when the old frame is sound. A full-frame replacement tears out the frame down to the studs, which is what you need when the frame is rotted or you are changing the window size, and it costs more because it is more labor and often new trim. The ranges here assume a standard insert on a sound frame.

New efficient windows cut heating and cooling loss, and the savings are real, but they rarely pay back the full install cost in energy alone over a normal ownership period. The stronger case is comfort, quieter rooms, less drafts, easier operation, and the resale bump. If a window is broken, fogged between the panes, or painted shut, replacement is the clear call.

The per-window range covers the unit and a standard install. It usually does not cover repairing rotted framing or sills, replacing exterior trim or capping, painting, or any structural change to resize an opening. Lead-safe work on an older home and disposal of the old units can add a line too. These are what the on-site measure turns up that a quick estimate cannot.
