Total windows in the project. Per-window pricing discounts 5-10% on whole-house jobs (10+).
Both sashes slide vertically and tilt in for cleaning. The most popular replacement window in the US - balances cost, ventilation, and easy maintenance. The Angi-cited $300-$700 vinyl baseline refers to this type.
Baseline - cheapest, lowest maintenance, good insulation. Won't rot or need painting. The downside: it expands and contracts with temperature, so cheap vinyl warps over time. Buy a mid-range vinyl (not builder-grade) and it'll outlast the warranty.
Two panes with an insulating gas (argon or krypton) between them. The modern baseline - code-required in most climates. Cuts heat loss roughly in half vs single-pane. The right default for almost every replacement project.
New window unit goes into the existing frame - the old sash is removed, the frame stays. Cheaper (no trim or siding work) and faster. The right call when the existing frame is square, plumb, rot-free, and you're keeping the same window size. Won't fix hidden water damage in the old frame.

How to Use This Calculator
1. Enter your window count.Whole-house jobs (10+ windows) typically get a 5-10% volume discount from contractors - that's baked into the per-window range, not subtracted separately.
2. Pick your window type. Double-hung ($300-$700) is the most common replacement. Single-hung is cheaper ($200-$450). Casement and awning ($400-$1,000) cost more for the crank hardware. Bay and bow windows ($1,000-$3,000) are the premium category - they project outside the wall and need structural header work.
3. Choose frame material. Vinyl is the baseline (cheapest, lowest maintenance, 20-30 yr). Aluminum is 15% cheaper but a poor insulator. Fiberglass (+40%) is strongest and longest-lasting. Wood (+50%) is the most expensive but adds resale value.
4. Select your glass package. Double-pane is the modern baseline. Low-e coating (+15%) is almost always worth it. Triple-pane (+40%) only pays back in extreme cold climates. Picking low-e or triple-pane unlocks the energy savings estimate.
5. Set installation method and region.Insert (pocket) replacement is ~25% cheaper than full-frame but only works when the old frame is sound. Region adjusts for local labor rates and energy-code requirements.
What Changes Your Window Replacement Cost
1. Window type (10x range)
A single-hung runs $200-$450 installed; a bay or bow window runs $1,000-$3,000+. The type is the single biggest cost driver after count. Bay and bow windows cost more because they project outside the wall - that means structural header work, a cap or roof, interior seat finishing, and multiple joined units. Picture windows have no moving parts but large glass still drives the price up.
2. Frame material (1.7x range)
Aluminum (0.85x) is cheapest but conducts heat - a poor choice for heated homes. Vinyl (1.0x) is the right default for most projects. Fiberglass (1.4x) is the contractor-preferred premium - strongest, longest-lasting, best efficiency. Wood (1.5x) is most expensive and needs repainting, but it's the only frame that adds resale value. For a forever home, fiberglass or wood-clad pays back; for a starter home, vinyl is the smart money.
3. Glass package (2x range)
Single-pane (0.7x) is largely obsolete for heated homes. Double-pane (1.0x) is the modern baseline and code-required in most climates. Low-e coating (1.15x) reflects heat and pays back in a few years. Triple-pane (1.4x) is only worth it in extreme cold climates or noisy streets - in mild climates the payback can exceed the window's lifespan. The glass choice also drives your energy savings.
4. Installation method (insert vs full-frame)
Insert (pocket) replacement reuses the existing frame and costs about 25% less. Full-frame replacement tears the window out to the rough opening and costs 25% more - but it's required when the old frame is rotted, out of square, or you're resizing. The trap: a contractor quoting insert without inspecting the frame is burying hidden rot. Always require a frame inspection before agreeing to insert.
5. Region and labor (1.3x range)
The West Coast is the most expensive (25% over national) due to high labor rates and California Title 24 energy code. The Northeast runs 15% over for cold-climate glass demand. The Southeast runs 5% under. Local labor varies 30%+ between regions, and energy code (IECC climate zone) can rule out the cheapest glass. Hurricane zones may need impact-rated glass - a separate premium not captured here.
Window Replacement Cost Breakdown: What You're Paying For
| Component | % of Total | What it covers |
|---|---|---|
| Window units (frame + glass) | 45-55% | The window itself - frame material (vinyl, wood, fiberglass, aluminum) and glass package (double, low-e, triple). The single biggest cost driver; premium materials and triple-pane push this toward 55%. |
| Labor (removal + install + trim) | 30-40% | Old window removal, new unit setting, leveling, insulating, interior and exterior trim, finish work. Full-frame installation adds 20-30% labor vs insert because the opening is exposed and re-trimmed. |
| Disposal (old windows + haul-away) | 5-8% | Old window haul-away and dump fees. Homes built before 1978 may need lead-safe removal (RRP rule), which adds labor and containment cost per window. |
| Permit + overhead + contractor profit | 8-12% | Building permit (where required), contractor insurance, equipment, scheduling, and profit margin. Many jurisdictions don't permit window swaps, but egress and full-frame changes often trigger one. |
Premium materials and triple-pane glass push the window-unit share toward 55%; full-frame installation and rot repair push the labor share toward 40%. Disposal is a small percentage that can spike on pre-1978 homes requiring lead-safe removal.
Insert vs Full-Frame Replacement: Which Do You Need?
The installation method is a 25% cost swing and the single most common quoting trap in window replacement. Use this matrix before you accept a quote.
| Factor | Insert (pocket) | Full-frame |
|---|---|---|
| Cost vs baseline | 1.0x (cheapest) | 1.25x (+25%) |
| What stays | Existing frame and trim | Nothing - opening exposed to rough framing |
| When to use | Frame is square, plumb, rot-free, same size | Frame rotted, out of square, or resizing |
| Hidden rot | Not addressed - covered up | Exposed and fixed before new window goes in |
| Trim work | Minimal - existing trim reused | New interior and exterior trim required |
| Time per window | 30-60 minutes | 2-4 hours |
The rule of thumb: if the existing frame has any visible water damage, soft wood, or the sash doesn't sit level, budget for full-frame. The extra 25% fixes the underlying problem instead of covering it up. If the frame is sound and you're keeping the same size, insert replacement is the smarter buy. Always require an in-person frame inspection before a contractor commits to insert.
Is the Energy-Efficient Glass Upgrade Worth It?
The glass package is the one upgrade with a measurable payback. Energy Star estimates that upgrading old single-pane windows to efficient double-pane with low-e coating saves $15-$30 per window per year in heating and cooling, depending on climate. On a 10-window project, that's roughly $150-$300 per year, or $3,000-$6,000 over 20 years - often enough to offset the low-e premium several times over.
Low-e coating (+15%): almost always worth it
Low-e is a microscopic metallic layer that reflects heat back to its source. In winter it keeps heat in; in summer it keeps heat out. It adds about 15% to the window and typically pays back within a few years. In hot climates (South, Southwest) it cuts cooling load; in cold climates (Northeast, Mountain) it cuts heating load. Unless you're replacing a garage or outbuilding window, low-e is the right default.
Triple-pane (+40%): only in cold climates or noisy sites
Triple-pane adds a third glass layer and a second gas-filled gap. It's 30-50% more expensive than double-pane and insulates better, but the payback period is long. In extreme cold climates (Mountain states, Northern Midwest) or on noisy streets where the extra sound insulation matters, triple-pane earns its premium. In mild or moderate climates, the payback can exceed the window's 20-30 year lifespan - skip it and put the money into low-e on more windows instead.
This calculator surfaces the energy savings estimate automatically when you pick low-e or triple-pane glass, so you can compare the upgrade cost against the 20-year savings in the same view.
How Location Affects Your Cost
| Region | Labor | Materials |
|---|---|---|
| National average | 1x | 1x |
| Northeast (cold climate, high labor) | 1.15x | 1x |
| West Coast (high labor, strict energy code) | 1.25x | 1x |
| Southeast (mild climate, lower labor) | 0.95x | 1x |
| Midwest & Mountain (cold, freeze-thaw) | 1.1x | 1x |

Red Flags in Contractor Quotes
We've reviewed hundreds of quotes. These are the warning signs that a contractor may cut corners or overcharge:
- Quoting insert replacement without inspecting the frame: insert (pocket) replacement is only safe when the existing frame is square, plumb, and rot-free. A contractor who quotes insert over the phone or without probing the old frame is burying hidden rot - and you'll pay to fix it after the new window is in. Always require an in-person frame inspection before agreeing to insert.
- Pushing triple-pane in a mild climate: triple-pane glass adds 30-50% to the window and only pays back in extreme cold. A contractor in the Southeast or mild West Coast pushing triple-pane on every opening is upselling, not engineering. In mild climates double-pane with low-e is the right call and the savings rarely cover the upgrade.
- No mention of Lead RRP for pre-1978 homes: if your home was built before 1978, federal law requires lead-safe work practices (RRP rule) on window replacement - the contractor must be RRP-certified. A contractor who doesn't ask the age of your home or mention lead containment is either uninformed or cutting corners on a federal requirement.
- One quote, one brand: a contractor who only installs one brand will recommend that brand regardless of your budget or needs. Window brands (Andersen, Marvin, Pella) have different price points and strengths. Get quotes from at least two contractors carrying different brands, and compare the spec - not just the name.
- Skipping the egress check on bedrooms: bedroom windows must meet egress (escape) size minimums - replacing a bedroom window with a smaller unit is a code violation and a fire-safety failure. A contractor who doesn't verify egress on bedroom openings is exposing you to failed inspection and a real hazard. Confirm the new unit meets local egress before it's ordered.
- Vague warranty or 'lifetime' with no fine print: 'lifetime' window warranties are famously full of fine print - some are lifetime of the glass seal only, some prorate after 5 years, some don't cover labor to reinstall. Get the actual warranty document, and ask who honors it if the contractor goes out of business (most manufacturer warranties do; most labor warranties don't).
Frequently Asked Questions
How does this window replacement cost calculator work?
Enter how many windows you're replacing, then pick the window type (single-hung, double-hung, casement, sliding, awning, picture, or bay/bow), frame material (vinyl, aluminum, fiberglass, wood), glass package (single, double, low-e, triple-pane), installation method (insert or full-frame), and your region. The calculator starts from a per-window base price for your type - the Angi-cited $300-$700 vinyl double-hung baseline - then multiplies it by frame, glass, installation, and region factors from 2026 HomeAdvisor and Angi data. Old-window disposal ($50-$100 per window) is itemized separately. If you pick low-e or triple-pane glass, it also estimates your annual energy savings so you can see the payback, not just the upfront cost.
How much does it cost to replace a window in 2026?
A replacement window costs $300 to $2,500 per window installed in 2026, with the national average around $600-$1,000. A standard double-hung vinyl window (the most common replacement) runs $300-$700 installed. Upgrading to wood or fiberglass frames, triple-pane glass, or full-frame installation pushes the per-window cost to $1,000-$2,500. Bay and bow windows are the premium category at $1,000-$3,000+ each because they project outside the wall and require structural header work. For a full house (10-15 windows), expect $4,000-$12,000 for standard vinyl and $15,000-$30,000+ for premium wood or fiberglass with triple-pane.
Which window type is cheapest, and which is most expensive?
Single-hung windows are cheapest at $200-$450 installed - only the bottom sash opens, so they cost less to build than double-hung. Double-hung ($300-$700) is the most popular replacement because both sashes tilt in for cleaning. Casement and awning ($400-$1,000) cost more due to the crank hardware. Sliding windows ($350-$900) are mid-range. Picture windows ($500-$1,500) have no moving parts but large glass drives the price. Bay and bow windows ($1,000-$3,000) are the most expensive - they're multi-unit assemblies that project outside the wall and need structural support, a cap or roof, and interior seat finishing. Pick the type by the opening and the function, not just the price.
Vinyl vs wood vs fiberglass windows - which frame is best?
Vinyl ($300-$700 baseline) is the right default for most homeowners - cheapest, lowest maintenance, good insulation, 20-30 year lifespan. Aluminum (15% cheaper) conducts heat and is a poor choice for heated homes; reserve it for garages or mild climates. Fiberglass (40% more than vinyl) is the contractor-preferred premium - strongest, won't warp, 30-50 year lifespan, best efficiency. Wood (50% more than vinyl) is the most expensive and needs repainting every 5-8 years, but it's the only frame that adds resale value and offers classic aesthetics. For a forever home, fiberglass or wood-clad pays back; for a starter home you'll sell in 10 years, mid-range vinyl is the smart money.
Is triple-pane or low-e glass worth the upgrade?
Low-e coating (about 15% more) is almost always worth it - it reflects heat back to its source, cutting both heating and cooling costs, and typically pays back within a few years. We estimate low-e or triple-pane saves $15-$30 per window per year versus single-pane. Triple-pane (40% more) is the harder call: it only pays back in extreme cold climates (Mountain, Northern Midwest) or on noisy streets where the extra sound insulation matters. In mild or moderate climates, the payback period can exceed the window's 20-30 year lifespan. The practical rule: low-e everywhere, triple-pane only in cold climates or noise-sensitive sites. For a 10-window project with low-e, that's roughly $150-$300 in annual savings - $3,000-$6,000 over 20 years.
Insert vs full-frame window replacement - which do I need?
Insert (pocket) replacement puts the new window into the existing frame - cheaper (about 25% less), faster, and the right call when the old frame is square, plumb, rot-free, and you're keeping the same size. Full-frame replacement tears out the entire window down to the rough opening and costs about 25% more, but it's required when the old frame is rotted, out of square, or you're changing the window size. The trap: a contractor quoting insert without inspecting the frame is burying hidden rot. If your old windows have any visible water damage, soft wood, or the sash doesn't sit level, budget for full-frame - the extra cost fixes the underlying problem instead of covering it up. When in doubt, ask the contractor to probe the frame before quoting.
How much does it cost to replace all the windows in a house?
Replacing all windows in a house costs $4,000 to $12,000 for a typical 10-15 window home with standard vinyl double-hung windows and insert installation. The same house with wood or fiberglass frames and triple-pane glass runs $15,000 to $30,000+. Bay or bow windows add $1,000-$3,000 each. Full-frame installation (when frames are rotted or you're resizing) adds about 25% to the total. Old-window disposal runs $50-$100 per window. The per-window price drops slightly on whole-house jobs because contractors discount for volume - expect 5-10% off on 10+ window projects. Get at least three quotes; whole-house window pricing varies 30%+ between contractors carrying different brands.
Does homeowners insurance cover window replacement?
Only for sudden, accidental damage - not age or wear. A tree falling through a window, a break-in, or a hailstorm is typically covered (after your deductible). Rotting frames, failed seals between glass panes, fogged glass, and normal aging are all considered maintenance and are excluded. If your window was damaged by a covered peril, document it with photos before any repair and file the claim promptly. If the damage is from settling, poor installation, or just old age, insurance won't pay - and a previous owner's unpermitted window change can complicate a claim. The best insurance for windows is buying units with a strong glass-seal warranty and keeping the documentation.
Real Project Example
10 Double-Hung Vinyl Windows, Low-E Upgrade - 1965 Ranch
Columbus, OH · 2026
A 1965 single-story ranch needed all 10 original single-pane wood windows replaced. The homeowner wanted energy efficiency without the premium of triple-pane or fiberglass - a low-e vinyl double-hung upgrade was the right call for the Midwest climate and the budget.
How It Went Down
Frame inspection
Contractor probed all 10 frames for rot and squareness
8 frames were sound and qualified for insert replacement. 2 windows near a leaking hose bib had minor frame rot and required full-frame - caught before quoting, not after
Lead RRP setup
Pre-1978 home triggered EPA Lead RRP rule - contractor set up containment
Built 1978 cutoff: this 1965 home required RRP-certified contractor, plastic sheeting, and lead-safe removal. Added about $40/window to disposal cost. A non-certified contractor would have been illegal and unsafe
Insert replacement (8 windows)
Removed old sash, set new vinyl units into existing frames, insulated gaps
About 45 minutes per window. Existing interior trim reused. Low-e double-pane units ran $580 each installed - the Angi baseline range
Full-frame replacement (2 windows)
Tore out rotted frames, sistered jack studs, installed new units with new trim
About 3 hours each. The rot was limited to the sill and lower side jamb - caught early. Full-frame added about $180 per window over insert, but fixed the cause of the rot
Egress check + finish
Verified bedroom windows met egress minimums, finished interior trim, final cleanup
Both bedroom windows met egress - a relief, since undersizing a bedroom window fails inspection. Total project $7,400, or $740/window blended across insert and full-frame
What we learned: The $7,400 total was $1,800 less than a full-frame-everywhere quote from a second contractor - because the first contractor inspected the frames and found 8 of 10 sound. The 2 full-frame windows added 25% to their own cost but fixed rot that would have leaked into the new windows within years. The low-e upgrade added about $870 to the project and is estimated to save $200-$300/year - a 3-4 year payback. The lesson: frame inspection before quoting separates honest contractors from the rest, and low-e pays back faster than any other window upgrade.
