How much does window replacement cost? Most windows run $450 to $1,200 each installed, with a national average around $800 per window, though basic vinyl units can start near $400 and large bay or bow windows can top $3,000. Labor alone is usually $150 to $300 per window. A whole-house project of 10 windows commonly lands around $5,000 to $12,000. Window replacement is priced per window, but the per-window number depends heavily on the frame material, the glass package and whether the crew can drop new units into the old openings or has to rebuild the frames. This calculator gives you a per-window window replacement estimate so you can budget the whole house or just a few.
What affects window replacement cost
The headline size of the job is only part of the story. Two jobs that look identical can be quoted very differently based on access, condition and how much cleanup is involved. Here is what a crew is actually pricing when they quote you.
Number of windows
The count is the base of the quote, and per-window pricing usually drops a little as the job gets bigger, since the crew is already set up.
Frame material
Vinyl, wood, fiberglass and aluminum-clad frames sit at very different price points. Vinyl is typically the value choice; wood and fiberglass cost more.
Glass package
Double versus triple pane, low-E coatings and gas fills all change the price and the energy performance of each unit.
Install type
An insert or retrofit that reuses the existing frame is faster and cheaper. A full-frame replacement that rebuilds the opening costs more but fixes rot and drafts.
Size and shape
Large picture windows, bays, and custom or arched shapes cost far more per unit than standard double-hung windows.
Trim and finishing
Interior trim, exterior capping and paint touch-up are extra labor beyond dropping the window in.
Labor and installation
Installation labor runs about $150 to $300 per window, more for second-story or hard-to-reach openings. It is a big share of the per-window cost, and where a careful crew earns its price.
Energy efficiency and rebates
Low-E, double or triple-pane and Energy Star windows cost more up front but cut heating and cooling bills and can qualify for rebates or tax credits that offset part of the project.
Window replacement cost by size
A quick reference for how the planning range shifts with size, at standard conditions and before extras. Use the calculator above to fine-tune it to your job.
| Job size | Typical number of windows | Planning range | What it looks like |
|---|---|---|---|
| Small | ~5 windows | $2,550 – $3,450 | A few windows, roughly 1 to 5, standard vinyl double-hung, insert install. |
| Medium | ~13 windows | $6,630 – $8,970 | A partial or single-story home, roughly 8 to 12 windows, standard sizes. |
| Large | ~21 windows | $10,710 – $14,490 | A whole-house job, 15 and up, or premium frames and larger custom units. |
Typical US ranges from public cost data. Real quotes move with region, season and the specifics of your site.
Window replacement cost by frame material
Frame material is one of the biggest swings in the per-window price. Here is how the common options compare, installed, for a standard double-hung window.
| Frame material | Cost per window (installed) | Best for |
|---|---|---|
| Vinyl | $450 to $900 | The value choice, low maintenance |
| Aluminum | $500 to $1,000 | Slim frames, warmer climates |
| Wood | $800 to $1,600 | Classic look, needs upkeep |
| Fiberglass or composite | $900 to $1,800 | Strength and efficiency, low upkeep |
| Bay or bow (any material) | $1,500 to $3,500+ | Large multi-panel feature windows |
Typical US installed ranges for one window. Glass package, size, install type and labor move the final price. Use the calculator above for a whole-house estimate.
What window replacement includes, and what costs extra
A low quote and a high quote often differ less on price and more on what is actually in the number. Confirm where these land before you compare.
- The new windows and standard installation
- Removing and disposing of the old units
- Basic sealing and insulation around the frame
- Labor and materials
- Full-frame replacement where openings need rebuilding
- Interior trim and exterior capping
- Custom shapes or oversized units
- Rot repair found during removal
- HVAC Replacement Cost Calculator → the other big energy upgrade
- House Painting Cost Calculator → often paired with new trim
Insert vs full-frame window replacement cost
The installation type is a big swing in window replacement cost. An insert or retrofit drops a new window into the existing frame, which is faster and cheaper, usually $450 to $1,000 per window installed. It is the right call when the old frame is sound and square.
A full-frame replacement tears out the old frame down to the studs and rebuilds the opening, which costs more, often $700 to $1,500 or more per window, but fixes rot, water damage and drafts and lets you change the window size. If the frames are failing, the extra installation cost is worth it.
How to save on window replacement
- 1Book in the off-season. Crews quote lower when the calendar is slow. If the job is not urgent, waiting for the quiet months is the easiest way to save.
- 2Get three quotes. Pricing for the same job routinely spreads by hundreds of dollars. Three quotes keeps everyone honest.
- 3Bundle nearby work. A crew already set up at your property will price a second job far cheaper than a separate visit.
- 4Be flexible on scheduling. Filling a gap in a crew's week is worth a discount to them, and to you.
Before you hire
Get proof of liability insurance in writing, be wary of anyone demanding a large deposit up front or quoting sight-unseen, and prefer a pro who walks the job and puts the scope in writing. A legitimate contractor will never need the full amount before the work is done.
- Walks the site before pricing it
- Puts the full scope in writing
- Shows current liability insurance
- Charges a reasonable deposit, if any
- Quotes a firm price sight-unseen
- Demands the full amount up front
- Cannot show proof of insurance

How this estimate is calculated
This calculator does not phone home or track you. When you press Calculate, the size, difficulty and extras you pick are sent to our server, run through a transparent cost model, and returned as a low-to-high planning range. It is deliberately a range, not a single number, because the same job is priced differently by every crew and every region.
The ranges come from public US cost data and current contractor pricing, cross-checked against real quotes, and the review team re-checks them as prices move. Treat the output as a solid planning range, then get local quotes to pin down the exact number for your job, region and season. Read the full methodology for how we build and check every tool.
Window Replacement Cost Calculator FAQ
How accurate is this estimate?
It is a planning range, not a quote. It is calculated server-side from the size, difficulty and extras you choose, using a cost model built from public US cost data and real quotes. Always get local quotes before you budget firmly.
Is the calculator free?
Yes, completely free, with no account and no tracking. We make money when you choose to get matched with local pros, which is always optional.
Why do quotes vary so much?
Access, condition, region and season all move the price, sometimes by 30 to 50 percent for the same job. That is why we show a range and recommend three quotes.
How much does window replacement cost?
Most windows run $450 to $1,200 each installed, with a national average around $800 per window. Basic vinyl units start near $400, while large bay or bow windows can top $3,000. A whole-house project of 10 windows is commonly $5,000 to $12,000.
How much does it cost to replace one window?
A single window runs $450 to $1,200 installed depending on frame material, glass and size, with labor of $150 to $300 of that. Standard vinyl double-hung windows are at the low end, custom and bay windows at the high end.
How much does labor cost to install a window?
Installation labor is about $150 to $300 per window, more for second-story or hard-to-reach openings. Full-frame installs cost more labor than a simple insert because the crew rebuilds the opening.
Is it cheaper to replace all windows at once?
Usually yes, per window. A crew that is already set up and buying in volume can price a whole-house job lower per unit than replacing a few at a time.
Insert or full-frame replacement?
Insert windows are cheaper and faster and work when the existing frame is sound. Full-frame replacement costs more but is the right call if there is rot, water damage or you want to change the size.
Which window frame material is cheapest?
Vinyl is typically the cheapest and lowest-maintenance frame material, at $450 to $900 installed. Wood and fiberglass cost more but offer a classic look or extra strength and efficiency.
Do new windows really cut energy bills?
Efficient low-E, double or triple-pane windows reduce drafts and heat loss, and can qualify for rebates or tax credits, but the payback is gradual. Weigh comfort and resale value alongside the energy savings.
What factors affect window replacement costs?
The number of windows, the frame material, the glass package and the install type set your total. Larger or custom replacement windows cost more, and second-story installs run higher than ground-floor ones. A single premium replacement window can cost as much as three basic ones. Get two or three local estimates on the same replacement windows, and use the window replacement cost calculator above to sanity-check the total.
