2026 Window Replacement Cost Index
Updated 2026-07-02
A standard vinyl window replacement costs $450 to $900 installed per window in 2026 on this site's own calculator model, and the broader US contractor market averages $850 per window nationally, per HomeAdvisor data updated June 17, 2026. Fiberglass and wood windows run higher, and bay windows or full-frame installs add a real premium on top of the base price. Every figure below carries its source and the date it was checked, and the full table downloads as a CSV.
Modeled cost per window, by material and type
These ranges come directly from the constants behind this site's own window replacement calculator: a $450 to $900 national baseline for a standard vinyl window installed as a retrofit insert, adjusted by the same material, window-type, and install-method multipliers the calculator applies. ZIP-level regional adjustment is left out here so the table shows one national baseline; plug in a ZIP on the calculator to localize any row.
| Material | Window type | Install method | Modeled range (per window) |
|---|---|---|---|
| Vinyl | Standard (double-hung/slider) | Insert (retrofit) | $450 - $900 |
| Vinyl | Standard (double-hung/slider) | Full-frame replacement | $590 - $1,170 |
| Vinyl | Casement / picture | Insert (retrofit) | $540 - $1,080 |
| Vinyl | Bay / bow | Insert (retrofit) | $1,130 - $2,250 |
| Fiberglass | Standard (double-hung/slider) | Insert (retrofit) | $630 - $1,260 |
| Wood | Standard (double-hung/slider) | Insert (retrofit) | $720 - $1,440 |
| Wood | Bay / bow | Full-frame replacement | $2,340 - $4,680 |

How the model compares to the contractor market
HomeAdvisor's window replacement cost page, updated June 17, 2026, puts the national average at $850 per window installed, with a full market range of $300 to $2,100 once size, brand, and labor market are factored in. Its per-material ranges run wider than this site's modeled ranges because they cover every job condition nationally, not one baseline configuration:
| Material | HomeAdvisor market range (per window) |
|---|---|
| Aluminum | $75 - $400 |
| Vinyl | $100 - $900 |
| Wood | $150 - $1,300 |
| Composite | $300 - $1,200 |
| Fiberglass | $500 - $1,500 |
| National average, all materials | $850 |
The two sets of numbers agree on the ordering (aluminum and vinyl cheapest, fiberglass and wood dearer) even though the exact bounds differ, because HomeAdvisor's range includes larger and more complex jobs than this site's single baseline configuration.
Does window replacement pay for itself at resale?
Not entirely, but more than most remodeling projects. The JLC (Journal of Light Construction) 2025 Cost vs Value Report found that a vinyl window replacement project with an average job cost of $22,073 added $16,657 in resale value nationally, a 76% cost recoup rate. The remaining 24% shows up elsewhere: lower heating and cooling bills for as long as you own the home, and fewer inspection concessions when you eventually sell.

Worked example
Take a 12-window house getting standard vinyl windows installed as retrofit inserts, no ZIP adjustment. At $450 to $900 per window, 12 windows runs $5,400 to $10,800 installed. Swap to fiberglass and the same job runs $7,560 to $15,120. Swap again to wood with full-frame installation, because the old frames are rotted, and the per-window price rises to $940 to $1,870, so the 12-window job runs $11,230 to $22,460. Material and install method move the total more than almost anything else in the job.
Methodology
- Modeled ranges: computed from windowreplacecost.net's own calculator constants: a $450 to $900 base range for a standard vinyl window installed as a retrofit insert, multiplied by the calculator's own material multipliers (vinyl 1.0, fiberglass 1.4, wood 1.6), window-type multipliers (standard 1.0, casement/picture 1.2, bay/bow 2.5), and install-method multiplier (insert 1.0, full-frame 1.3). No ZIP regional multiplier is applied, so these are national baselines. Reviewed 2026-07-02.
