Updated September 2026. Resale data: 2025 Cost vs. Value Report (Zonda/JLC), national and selected market averages.
New windows are worth it when your current ones are failing or you will live with the new ones for many years. As a pure resale investment, they usually lose money: nationally, a vinyl window replacement recoups about 75.5% of its cost when the home sells, which ranks well below exterior projects like a new garage door or steel entry door.

How windows compare with other exterior projects
Windows are a solid project, but they are not the resale winner many sales pitches suggest. Here is how they rank against other common exterior replacements in the same national report.
| Project | Job cost | Resale value added | Cost recouped |
|---|---|---|---|
| Garage door replacement | $4,672 | $12,507 | 267.7% |
| Entry door replacement, steel | $2,435 | $5,270 | 216.4% |
| Siding replacement, fiber-cement | $21,485 | $24,420 | 113.7% |
| Siding replacement, vinyl | $17,950 | $17,313 | 96.5% |
| Grand entrance, fiberglass | $11,754 | $9,959 | 84.7% |
| Window replacement, vinyl | $22,073 | $16,657 | 75.5% |
| Window replacement, wood | $26,781 | $18,764 | 70.1% |
| Roof replacement, asphalt shingles | $31,871 | $21,501 | 67.5% |
Source: 2025 Cost vs. Value Report, Zonda/JLC, national averages. Cost recouped = resale value added ÷ job cost.
The pattern is consistent: cheap, highly visible projects return the most. Windows are expensive and buyers tend to notice them only when they look bad.
What “cost recouped” really measures
The Cost vs. Value numbers are useful, but read them for what they are. Job costs are estimated with remodeling estimating software for a defined midrange project. Resale value is based on surveys of real estate professionals estimating how much the project would add to a home’s sale price. It is not an appraisal, and it is not a record of actual sales.
That means the figure answers a narrow question: if you replaced your windows right before selling, how much more might a buyer pay? It says nothing about comfort, lower bills or avoided repairs during the years you live there.
Your market changes the answer
The national 75.5% hides wide local differences. In the same 2025 report, the vinyl window project was estimated to recoup:
| Market | Job cost | Cost recouped |
|---|---|---|
| Washington, DC | $21,510 | 103.5% |
| Las Vegas, NV | $20,975 | 93.7% |
| Virginia Beach, VA | $20,462 | 90.8% |
| Sarasota, FL | $20,688 | 84.6% |
| National average | $22,073 | 75.5% |

Energy savings: why the estimates are all over the place
Window sellers often quote large energy savings, and the honest answer is that it depends on four things:
- What you’re replacing. Swapping single-pane windows is a very different upgrade from replacing 20-year-old double-pane units that still seal.
- Your climate. Savings are larger where heating or cooling runs most of the year.
- Your energy prices. The same kilowatt-hours saved are worth more in high-rate states.
- Where the leaks really are. Air often escapes around the frame, not through the glass. A poor installation can erase much of the benefit of efficient glass.
For a grounded estimate, compare 12 months of utility bills before and after on a similar project in your area, or ask for an energy audit that measures air leakage before you buy.
The break-even math
Here is a simple way to decide, using your own numbers. The example uses the national Cost vs. Value figures and a hypothetical savings amount; replace it with a figure that fits your home.
Net cost of new windows if you sell after N years = project cost − resale value added − (annual energy savings × N)
- Project cost: $22,073
- Resale value added: $16,657, leaving a gap of $5,416
- Hypothetical energy savings: $300 per year
- Sell after 5 years: $5,416 − $1,500 = $3,916 net, about $65 per month for the comfort and reduced maintenance
- Sell after 15 years: $5,416 − $4,500 = $916 net, assuming the resale boost holds up (it usually fades as windows age)
Framed this way, the question stops being “will I get my money back?” and becomes “is roughly this much per month worth a quieter, less drafty home with windows I don’t have to fix?” For many owners of homes with failing windows, the answer is yes.
When repair beats replacement
- Foggy glass on a few windows. Replacing the sealed glass unit can be enough if the frame and sash are sound. See window glass replacement cost.
- Drafts on otherwise good windows. New weatherstripping and caulking are cheap first steps.
- Sticky or broken hardware. Balances, cranks and locks can usually be replaced individually.
- Historic wood windows. Restoration plus storm windows can preserve the home’s character.
Worth it if
- Frames are rotting or many seals have failed
- You have single-pane windows and real heating or cooling loads
- You’ll stay long enough to use the comfort, typically 10+ years
- Your local market shows strong cost recouped figures
Skip it (for now) if
- You’re selling soon and the windows aren’t a visible problem
- Your double-pane windows work and the pitch is mostly about energy savings
- You want the best resale return per dollar: a garage door or steel entry door does more
2026 note: the federal Section 25C tax credit for energy-efficient windows ended for installations after December 31, 2025, so it no longer shortens the payback period. Check state and utility rebates instead.
How we got these numbers
All cost and resale figures come from the 2025 Cost vs. Value Report by Zonda, national and city pages. Break-even calculations are our own, and the energy savings figure in the example is hypothetical by design, since real savings depend on the house. We will update this page when the 2026 report is published. Read our full methodology.
FAQ
Do new windows increase home value?
Yes, but typically by less than they cost. The 2025 national estimate for vinyl windows is $16,657 in added value on a $22,073 project, or 75.5% recouped.
Is it worth replacing windows before selling a house?
Usually only if the windows are visibly failing or likely to come up in an inspection. Otherwise, cheaper curb-appeal projects like a new front door recoup more per dollar.
How long do replacement windows take to pay for themselves?
Through energy savings alone, often many years, and sometimes longer than the windows last. The payback improves when you count resale value, comfort and avoided repairs.
Are vinyl or wood windows a better investment?
On national resale data, vinyl recoups a slightly higher share (75.5% vs. 70.1%) at a lower cost. Wood makes more sense when the home’s style calls for it.
