Powered by real-time pricing logic — based on your selected configuration.
This is an estimated cost. Actual pricing may vary depending on project complexity and local rates.
This calculator simplifies your window installation planning — whether you’re replacing one window or updating your entire property.
This calculator is ideal for homeowners, landlords, real estate investors, and contractors who want quick, transparent pricing without needing to call around.
This calculator helps you estimate the cost of window installation by walking you through a few simple inputs. Each selection affects your overall price estimate based on national averages and common project scenarios.
Window Type – Choose from single-hung, double-hung, casement, awning, sliding, bay/bow, and custom. Each varies in material and labor needs, impacting price.
Frame Material – Options include vinyl, wood, aluminum, and fiberglass. Vinyl is most budget-friendly, while fiberglass and wood offer better insulation at higher costs.
Window Size & Quantity – Enter how many windows you need and their approximate size (small, medium, large). Bigger and more windows raise both material and labor costs.
Glass Type – Select from single-pane, double-pane, triple-pane, or Low-E glass. Energy-efficient options cost more upfront but save on long-term energy bills.
Installation Conditions – Account for factors like floor level (ground to 5th), old window removal, and permit requirements — all of which affect total cost.
Instant Estimate Breakdown – After entering your details, you’ll get a real-time breakdown including:
Cost per window
Total estimated cost
Summary of all selections
Here are estimated average installed costs per window type, based on multiple leading sources. Prices vary by region, materials, size, and installer.
Window installation costs vary by style, material, and region. On average, most homeowners pay between $400 and $1,200 per window installed.
Double-hung windows typically cost $400–1,200, while single-hung run slightly cheaper at $300–700. Casement and slider windows usually range from $300–1,000, depending on size. Picture windows fall between $500 and $1,300. Bay or bow windows are more premium, costing anywhere from $1,400 to $6,000 or more per unit.
For Example:
| Scenario | Estimated Cost |
|---|---|
| 5 mid-range double-hung windows | $2,500 – $6,000 |
| 3 bay windows | $3,000 – $15,000 |
| Full-home (10+ windows) | $7,000 – $18,000 |
These estimates give a strong starting point.
Window installation costs don’t just depend on how many windows you’re replacing — several key details can significantly raise or lower your final estimate. This calculator factors in those variables to give you the most accurate, personalized result.
Material matters. Vinyl windows are typically the most affordable, making them a common choice for budget-conscious homeowners. Wood offers a premium, traditional look but requires maintenance and comes at a higher price. Fiberglass and composite materials are more durable and energy-efficient, but they also cost more upfront. Aluminum is sleek and long-lasting, but it insulates less effectively and may be better suited to mild climates.
Window style impacts pricing. Basic options like single- or double-hung windows are faster and cheaper to install. On the other hand, bay, bow, or custom-shaped windows require extra structural work and often cost significantly more — not just for the product itself, but for installation labor and support framing.
Glazing upgrades can change the game. Standard double-pane windows are common, but if you’re in a cold climate or want improved insulation, triple-pane options, Low-E coatings, and argon gas-filled layers can increase energy efficiency. These options add to the cost, but they can also reduce heating and cooling bills over time.
The installation method is another big factor. Insert (retrofit) installations are generally quicker and more affordable since they fit into the existing frame. Full-frame replacements are more complex and costly but often necessary in older homes. Historic homes, in particular, can require specialized installation approaches, permits, or custom materials — all of which increase costs.
Labor and location influence pricing, too. Contractors in urban or high-cost-of-living areas charge more on average. Access also matters — windows on upper floors, in tight spaces, or behind landscaping may require extra equipment and time.
All of these variables work together to influence your estimate. That’s why this calculator adjusts in real time as you select your project details — to help you see the full picture before you call a contractor.
To give you a clearer idea of what your window project might cost, here are realistic examples based on actual U.S. pricing averages. These examples assume standard installation without structural modifications or high-end customization.
If you’re installing five vinyl double-hung windows in a typical Chicago neighborhood, each window may cost around $500 to $900, including both materials and labor. That brings your estimated total to roughly $2,500 to $4,500. Opting for energy-efficient glass, Low-E coatings, or premium-grade materials could push that closer to $5,500.
For a full-home replacement with a mix of window types — such as 10 double-hung, 3 casement, and 2 picture windows — your per-window average might range between $600 and $1,200, depending on materials and features. The total project estimate would typically fall between $9,000 and $16,000, with higher-end installations possibly exceeding $18,000.
These scenarios are based on national pricing trends and reflect real contractor estimates found across the U.S. Your actual costs may vary depending on local labor rates, installation complexity, frame material, and add-ons like Low-E glass or triple-pane insulation.
This calculator gives a ballpark estimate based on national pricing data and your ZIP code. While it’s close to real contractor quotes, final pricing can vary depending on brand, custom features, or structural conditions.
Late spring and early fall are ideal. These seasons offer mild weather, shorter contractor wait times, and often lower labor rates compared to peak summer or winter demand.
DIY window installation is possible for experienced homeowners, but hiring a pro ensures proper sealing, structural fit, and code compliance. Professional installation can also protect your product warranty.
Order in bulk if replacing multiple windows, choose standard sizes, and look for seasonal discounts. You may also qualify for federal or state energy-efficiency rebates or utility-based upgrade programs.
Yes — energy-efficient windows with double or triple glazing, Low-E coatings, and gas fills reduce heating and cooling costs. They typically pay off over time through energy savings and may boost home resale value.
