Preliminary professional-installation estimate based on your selections.
Actual prices vary by exact dimensions, manufacturer, product series, glass package, frame condition and installation requirements.
How This Window Replacement Cost Calculator Works
The calculator starts with the number and style of windows being replaced. Each window style has its own broad installed price range because a standard single-hung window is fundamentally different from a large bay or bow window.
Frame material, glass package, size and installation method then make moderated adjustments to that range. Additional frame repairs remain separate so they are not automatically charged to every project.
Average Window Replacement Cost in 2026
Window replacement costs approximately $450 to $1,500 per window for a typical single-hung window with professional installation. A project involving 10 to 15 windows commonly costs approximately $4,500 to $22,500.
The national average reported by HomeGuide is about $900 per replacement window. Angi reports an average whole project cost of approximately $7,347 in 2026.
Window Replacement Cost by Number of Windows
| Number of windows | Typical installed cost |
|---|---|
| 1 window | $450–$1,500 |
| 2 windows | $900–$3,000 |
| 5 windows | $2,250–$7,500 |
| 10 windows | $4,500–$15,000 |
| 15 windows | $6,750–$22,500 |
| 20 windows | $9,000–$30,000 |
| 25 windows | $11,250–$37,500 |
These ranges are based on standard single-hung windows in basic aluminum or vinyl frames. Larger, custom and premium windows can cost more.
Window Replacement Cost by Type
| Window type | Typical installed cost per window |
|---|---|
| Single-hung | $300–$2,100 |
| Double-hung | $350–$2,500 |
| Awning | $400–$2,000 |
| Casement | $400–$3,000 |
| Bay | $2,000–$6,000 |
| Bow | $3,000–$8,000+ |
| Egress | $3,000–$7,000 |
| Hurricane / storm | $400–$1,200 |
Window Replacement Cost by Frame Material
Frame material can make a major difference in the price of replacement windows. HomeGuide reports approximately $175 to $1,000 installed for aluminum, $200 to $1,500 for vinyl, $400 to $2,000 for fiberglass, $400 to $2,300 for composite and $800 to $3,800 for wood windows.
These ranges include multiple window sizes and styles, so material prices should not simply be added to a separate installed window price.
How Much Do Vinyl Replacement Windows Cost?
Vinyl replacement windows typically cost approximately $350 to $1,500 each including installation. Vinyl is widely used because it combines relatively affordable pricing with low maintenance and good energy performance.
How Much Do Wood Windows Cost?
Wood windows can cost approximately $800 to $3,800 each installed. Exact prices depend on window size, style, wood species, manufacturer and finish.
Because wood frames tend to be more expensive than basic vinyl or aluminum, they can significantly increase a whole-house replacement budget.
Double-Pane vs. Triple-Pane Window Cost
HomeGuide reports approximately $400 to $2,000 installed for double-pane windows and $450 to $3,000 for triple-pane windows across several common residential window styles.
Double-pane insulated glass is standard in many residential replacement projects. Triple-pane products cost more but can provide additional insulation.
Retrofit vs. Full-Frame Replacement
Retrofit replacement places the new window within an existing frame that remains structurally sound. Full-frame replacement removes the entire window assembly and exposes the rough opening.
Angi reports approximately $100 to $300 per window for retrofit work and about $180 to $1,500 for full-frame replacement, although these figures overlap with other project components and should not be added automatically to an installed window price.
How Much Does Window Installation Labor Cost?
HomeGuide estimates window replacement labor at approximately $100 to $500 per window. HomeAdvisor reports roughly $100 to $400 per window for professional installation.
The calculator does not add this amount separately because its primary window ranges already represent installed costs. Adding labor again would risk double-counting the same expense.
How Much Does It Cost to Replace 10 Windows?
HomeGuide estimates approximately $4,500 to $15,000 to replace 10 standard single-hung windows. Angi reports about $6,000 to $9,000 for projects involving roughly 8 to 12 standard double-hung windows.
Material, window style, glass and installation conditions explain much of the difference between projects.
How Much Does It Cost to Replace 20 Windows?
HomeGuide estimates approximately $9,000 to $30,000 for 20 standard single-hung replacement windows. Angi reports approximately $12,000 to $15,000 for projects involving 16 to 20 standard double-hung windows.
Whole-house projects may have a lower average price per window than replacing only one or two windows because some contractors offer volume pricing.
Window Frame Repair and Replacement Cost
Damage around an existing window can increase replacement costs. HomeGuide reports approximately $200 to $600 to replace a standard-size window frame and $600 to $1,200 for large, custom or complex frames.
Angi reports a 2026 national average of approximately $392 for frame replacement, with many projects falling between $184 and $616.
What Changes Window Replacement Cost?
Window style
Style is one of the biggest cost factors. Simple single-hung windows cost much less than large bay, bow and specialty windows.
Frame material
Aluminum and vinyl generally fall toward the lower end of the market, while fiberglass, composite and wood can increase the cost.
Glass package
Double-pane, Low-E and triple-pane products have different prices and energy-performance characteristics. Specialty glazing can further increase costs.
Window size
Large windows use more material and may require multiple installers to safely position the unit.
Existing frame condition
Rot, moisture damage or structural deterioration can turn a straightforward insert replacement into a more extensive full-frame project.
What Is Included in This Estimate?
The calculator’s primary ranges represent typical window units with professional installation. The exact inclusions depend on window type and contractor.
Optional frame or opening repairs are displayed separately because these repairs are not necessary for every replacement project.
What Is Not Automatically Included?
New wall openings, extensive structural modifications, major siding repairs, interior remodeling, lead or asbestos remediation and unusual custom fabrication are not automatically included.
Permit costs are also excluded because local requirements differ. Structural changes and new openings may require additional approvals.
Calculator Methodology
HomeFixLedger uses current 2026 U.S. installed window-replacement ranges as the baseline. Window type establishes the primary range because different styles have substantially different material and installation requirements.
Frame material, glass package, window size and installation method provide moderated adjustments to the installed range rather than being added as separate full prices. This approach reduces the risk of counting the same materials or labor twice.
Additional window-frame repairs are calculated separately only when selected. Standard-size frame replacement uses approximately $200 to $600 per affected window, while larger or more complex frame replacement uses approximately $600 to $1,200.
The calculator is intended for budgeting standard residential replacement projects, not designing new structural openings.
