Window Replacement Cost Calculator (2026)
By Dan Whitlock, Home Projects Editor · Updated July 2026
Replacement windows are priced per window, so the whole-house number depends mostly on how many you do and what frame material you choose. In 2026, a standard vinyl window runs about $350–$800 installed, averaging near $575; fiberglass and wood cost meaningfully more. Full-frame replacement (versus a pocket/insert) and large or specialty shapes push the price up. Enter your window count below.

What drives your window replacement cost
- Frame material: vinyl is the value pick; fiberglass and wood cost 40–80% more.
- Insert vs. full-frame: full-frame replacement includes new framing and trim and costs more.
- Glass package: triple-pane, low-E, and gas fills add cost but cut energy bills.
- Size & shape: bay, bow, and arched windows cost multiples of a standard double-hung.
- Home age: rot repair or non-standard openings add labor.

Ways to save
- Do the whole house at once — crews price per-window cheaper at volume.
- Stick with vinyl unless you specifically need fiberglass durability or a wood look.
- Insert replacement is far cheaper than full-frame when the existing frames are sound.
- Standard sizes cost less than custom; avoid changing opening dimensions.
- Buy in the off-season (late fall/winter) when installers discount to stay busy.
Frequently asked questions
How much does it cost to replace a window in 2026?
A standard vinyl replacement window costs about $350–$800 installed, averaging ~$575. Premium vinyl, fiberglass, and wood run higher, and large or specialty shapes cost more still.
How much to replace all the windows in a house?
For a typical home with 8–12 windows in vinyl, budget roughly $3,000–$8,000. Fiberglass or wood, full-frame replacement, or a larger home push that higher.
Is vinyl or fiberglass better for the money?
Vinyl is the best value and performs well for most homes. Fiberglass costs about 40% more but is stronger, holds paint, and handles temperature swings better — worth it in extreme climates or for a premium look.
