Window replacement cost per window varies based on material, size, glass type, and installation difficulty. While some basic replacements cost only a few hundred dollars, larger or upgraded windows can cost well over a thousand dollars each.
This page breaks down what homeowners typically pay per window and why prices vary.
Average Window Replacement Cost Per Window
Most homeowners pay between $300 and $1,200 per window installed.
| Window Type | Installed Cost per Window |
|---|---|
| Vinyl window | $300 – $700 |
| Composite window | $600 – $1,200 |
| Wood window | $900 – $1,800 |
| Fiberglass window | $1,000 – $2,000 |
| Custom or oversized window | $2,000+ |
These prices include the window unit and standard installation.
Cost by Window Size
Larger windows require more materials and labor, increasing total cost.
| Window Size | Typical Cost Range |
|---|---|
| Small window | $300 – $600 |
| Standard window | $500 – $1,200 |
| Large window | $900 – $2,000 |
| Floor-to-ceiling or picture window | $1,500 – $3,500+ |
Non-standard sizes or shapes cost more due to customization.
Installation Factors That Affect Per-Window Cost
Window installation costs increase when:
- windows are on upper floors
- old frames are damaged
- masonry or stucco walls are involved
- structural modifications are required
Homes built before modern framing standards often cost more to retrofit.
Window Material Cost Differences
Material choice has a major impact on per-window cost:
- Vinyl: lowest cost, low maintenance
- Wood: higher cost, natural appearance, more upkeep
- Fiberglass: durable, energy-efficient, higher upfront price
Material choice also affects lifespan and maintenance requirements.
Glass and Efficiency Upgrades
Upgrades that increase per-window cost include:
- double or triple-pane glass
- low-E coatings
- gas-filled insulation
- soundproof or impact-resistant glass
Efficiency upgrades raise upfront cost but may reduce energy bills.
When Per-Window Costs Are Higher Than Average
You may pay more per window if:
- replacing a single window instead of multiple
- installing specialty or custom windows
- working with older or historic homes
Replacing several windows at once often lowers the average cost per window.
Bottom Line
Window replacement cost per window typically ranges from a few hundred dollars to over a thousand, depending on size, material, and installation complexity. Replacing multiple windows at once is usually more cost-effective than single replacements.
