Window Replacement Cost Calculator & Price Guide

Replacing a window typically costs $450 – $1,200 each per window installed, according to Fixr. The final price depends mostly on the frame material, the window style, and how many windows you replace in one project.

The tables below break the cost down by material, style, labor, and whole-house totals. Figures come from published guides and carry a check date of Oct 11, 2026.

The material is the largest single driver of the per-window price. Aluminum and vinyl sit at the lower end, while wood and fiberglass cost more. Two sources appear in the table, and their ranges differ: one reports a wider and lower spread, while Pella reports higher ranges for vinyl, fiberglass, and wood.

Style also changes the price. Windows that open, such as casements, cost more than fixed panes of the same size, and projecting units like bay and bow windows sit in a different price class altogether.

Labor is part of the installed per-window figure above, and some guides report it on its own. The labor number covers removing the old unit, fitting and sealing the new one, and finishing the interior trim.

Labor rises when the opening needs repair, when windows are on upper floors, or when the project involves changing the opening size. A full-frame replacement costs more than an insert replacement, which fits inside the existing frame.

• Frame material. Vinyl, aluminum, fiberglass, and wood differ in price, durability, and upkeep.
• Glass package. Double-pane or triple-pane glass, low-E coatings, and gas fills raise the unit price and can reduce energy loss.
• Style and size. Larger and more complex windows cost more, and custom shapes cost more still.
• Insert versus full-frame. Insert replacement keeps the existing frame. Full-frame replacement removes it and costs more, but it allows repair of rot or water damage behind the frame.
• Number of windows. Larger projects may get a lower per-window labor cost, since the crew mobilizes once.
• House height and access. Upper-floor windows take longer and may need extra equipment.
• Permits and rules. Some cities and historic districts require permits or specific window styles.
• Region. Labor rates and demand vary by area.

Many homeowners replace all windows at once. Totals depend on how many windows the house has, which is why the figures below differ by home size.

A three-bedroom house typically has somewhere between a dozen and two dozen windows, depending on layout, so the matching row depends on whether it is a single-story or two-story plan. Count your own windows and multiply by a per-window figure that fits your material and style for a more accurate estimate.

A quick budget calculation works like this:

1. Count the windows you plan to replace and group them by style, such as double-hung, picture, or bay.
2. Choose a frame material and find its range in the material table.
3. Multiply each group by a low and a high per-window figure to get a budget band.
4. Add extra for any special windows, trim work, or repairs to the openings.

The result is a planning range, and a written quote after an on-site measurement replaces it.

Guides report different numbers because they sample different jobs. Some include only the window and basic installation, while others include higher-end glass, trim, and finishing.

One source reports an average based on a typical project size, while others report ranges across the market. Differences in the share of premium materials, the regions covered, and what labor includes all affect the figures.

Repair can be a better value than replacement when the frame is sound. Common repairs include replacing a failed glass pane or seal, fixing a sash balance, and repairing a lock or latch. The sources used here report replacement rather than repair costs, so no repair figure appears in this guide. Request a repair quote alongside replacement quotes so you can compare them for each window.

Insert replacements are within reach for experienced DIYers, but poor flashing and sealing are a common cause of water intrusion and drafts. Full-frame work, upper-floor windows, and large units are more demanding and heavier. Manufacturer warranties often require installation by a certified installer, so check the terms before deciding.

• Is the price per window, and does it include removal and disposal of the old windows?
• Is the quote for insert or full-frame replacement?
• What are the glass specifications and the warranty terms on the glass, frame, and labor?
• Who handles permits and any lead-safe work practices needed for older homes?
• How will the installer protect the interior and flash the opening?

Get at least three written quotes with the same specifications so the numbers compare fairly.
