The average installed cost is $300–$1,200 per window, driven mostly by window type, frame material, and glass package. Most standard double-hung replacements land at $600–$800 installed. Here's the breakdown by window type:
| Window type | Installed cost per window |
|---|---|
| Single-hung | $250 – $600 |
| Double-hung | $400 – $900 |
| Casement | $500 – $1,200 |
| Sliding | $400 – $1,000 |
| Bay or bow | $1,500 – $4,500 |
| Picture / fixed | $400 – $1,200 |
Window cost by frame material
| Frame material | Cost per window (installed) | Notes |
|---|---|---|
| Vinyl | $300 – $800 | Most popular; low maintenance, energy-efficient |
| Fiberglass | $500 – $1,200 | Durable, stable, good insulation |
| Aluminum | $400 – $1,200 | Strong but conducts heat |
| Wood | $800 – $2,000+ | Premium look, more maintenance |
Whole-house window replacement cost
| Number of windows | Typical total cost |
|---|---|
| 5 windows | $3,000 – $6,000 |
| 10 windows | $6,000 – $12,000 |
| 15 windows | $9,000 – $18,000 |
| 20 windows | $12,000 – $24,000 |
What affects window replacement cost?
- Window type & size: casement and bay windows cost more than standard double-hung.
- Frame material: vinyl is cheapest; wood is priciest.
- Glass package: double- vs triple-pane, low-E coatings, and gas fills raise cost and efficiency.
- Full-frame vs insert: replacing the entire frame (needed if there's rot) costs more than an insert into the existing frame.
- Labor & location: installation rates vary by metro; older homes may need extra work.
Pro tip from our network contractors
If your goal is lower energy bills, spend on the glass package — low-E, double-pane with a good U-factor — before you spend on a premium frame material. That's where the comfort and savings come from.
Are there tax credits or rebates for new windows in 2026?
There is no federal tax credit for windows installed in 2026. The federal Energy Efficient Home Improvement Credit (IRS Section 25C) — which had covered 30% of the cost of qualifying ENERGY STAR windows, up to $600 per year — was ended by the One Big Beautiful Bill (signed July 2025) for any property placed in service after December 31, 2025. If your windows were installed on or before that date, you can still claim the credit on your 2025 federal tax return.
For 2026 installs, the savings now come from state and utility programs, not the IRS. Many states, cities, and local utilities still offer rebates for energy-efficient windows — search the free DSIRE database (dsireusa.org) for programs in your area, and ask your installer about current manufacturer rebates and financing. Incentive rules change often, so confirm the current terms with the program provider or a tax professional before relying on any of them.
Are new windows worth it?
Energy-efficient replacement windows reduce heating and cooling costs, improve comfort (fewer drafts), cut outside noise, and are attractive to buyers. They're among the more reliable home-improvement investments for resale, and the energy savings plus any available state or utility rebates shorten the payback period.
