Estimates based on national averages adjusted for your state. Actual costs depend on window size, accessibility, structural modifications, trim work, and contractor pricing. This is a planning tool, not a binding quote. Get at least 3 quotes from local contractors.
Planning Your Window Replacement?
Use this estimate to compare bids from local contractors. A good rule of thumb: get at least 3 quotes and ask about warranty coverage on both parts and labor.
This calculator estimates the total installed cost of replacing your windows across five common frame materials, based on your window count, type, and state.
Window costs use national average price ranges from contractor pricing surveys. Each window type has a base cost range, which is then multiplied by a frame material factor. For example, wood frames cost approximately 1.6x the base price of vinyl frames.
Regional multipliers reflect that labor and material costs vary across the country. States are grouped into four tiers: Low cost (rural South/Midwest, 0.85x), Average (most states, 1.0x), High (Northeast/West Coast, 1.15x), and Very High (NYC metro, Hawaii, Alaska, 1.30x).
Cost per year divides the total project cost by the expected lifespan of the frame material. This is the fairest way to compare options — vinyl is affordable upfront but lasts 25 years, while fiberglass costs more but can last 40+ years.
Energy savings are estimated using DOE data on window heat loss by climate zone. Windows account for 25–30% of residential heating and cooling energy use. Upgrading from single pane to double pane Low-E glass can cut window-related energy loss significantly, with the exact savings depending on your state's climate.
Frequently Asked Questions
How much does it cost to replace windows in a house?
The average cost to replace windows is $300–$750 per window for vinyl frames, or $500–$1,200 for wood or fiberglass. For a typical home with 12 windows, expect to pay $4,800–$14,400 total including labor. Costs vary significantly by window type (double hung vs. casement vs. bay), frame material, glass package, and your location. Use the calculator above with your specific details for a more accurate estimate.
What's the best window frame material?
It depends on your priorities. Vinyl is the best value for most homeowners — low cost, zero maintenance, and good energy efficiency. Fiberglass is the best long-term investment with 40+ year lifespans and superior durability. Wood offers the best aesthetics and can increase home value, but requires periodic painting or staining. Composite blends the low maintenance of vinyl with the strength of wood. Use the Cost/Year column in our calculator to find the true best value for your situation.
Are vinyl windows as good as wood?
For most homes, yes. Modern vinyl windows offer comparable energy efficiency, never need painting, resist moisture and insects, and cost 40–60% less than wood. Wood windows are superior in aesthetics (especially for historic homes), can be refinished to change color, and may add more resale value in high-end markets. If low maintenance and value are your priorities, vinyl is the better choice. If curb appeal and customization matter most, wood wins.
How long do replacement windows last?
Vinyl and aluminum windows typically last 20–25 years. Wood and composite frames last 30–35 years with proper maintenance. Fiberglass is the longest-lasting at 40+ years. Note that the glass sealed unit (IGU) may need replacement before the frame — dual-pane seals typically last 15–25 years before fogging occurs between panes. Quality of installation also plays a major role in longevity.
Do new windows increase home value?
Yes. According to Remodeling Magazine's Cost vs. Value report, window replacement typically recoups 60–75% of the investment at resale. For a $15,000 project, that's roughly $9,000–$11,000 in added value. Beyond resale, new windows reduce energy bills by $100–$400 per year, improve comfort by eliminating drafts, and reduce outside noise. Energy-efficient windows are one of the top features homebuyers look for.
Should I replace all windows at once?
Replacing all at once is usually more cost-effective. You'll save 5–10% through bulk pricing, pay only one mobilization fee, and get a consistent look. However, if budget is tight, prioritize the worst performers first: north-facing windows, any with visible condensation between panes, windows that don't seal properly, and single-pane windows. Replacing even a few windows can noticeably improve comfort and energy bills.
