Window Replacement Cost Calculator: 2027 Installed Prices

How to Use the Window Calculator

Work down the form from top to bottom:

1. Quantity by style. Count every opening and enter it under double-hung, two-lite slider or bay/bow. Mixed styles price together, so one pass covers the whole house.
2. Window material. Vinyl, wood, fiberglass or aluminum. The tradeoffs are covered below.
3. Low-E / argon gas. Pick Low-E at minimum. Most codes now call for it, so “None” is only there for comparison.
4. Build quality. Mostly a vinyl question. A maker’s wood or aluminum line is usually built to one standard.
5. Grids. Optional, about $40 per window, priced for the standard colonial pattern.
6. New trim. Existing interior stops can usually stay; new ones add roughly $70 to $110 per window installed. If the outside casing is painted wood, have it wrapped in aluminum coil stock for about $120 to $200 per window. No more scraping, painting or rot.

Product prices come from Harvey and Alside retail catalogs (no contractor discount), labor is an average, and the total is adjusted for your region. Real bids will still swing with the crew and the local market.

How Much Do Replacement Windows Cost?

A standard vinyl double-hung runs roughly $510 to $1,070 installed, depending on build grade. Wood, aluminum and fiberglass double-hungs mostly land between $760 and $1,640 per opening.

For a typical 10-window job, figure about $4,600 to $9,220 in vinyl, or roughly $7,540 to $16,330 in wood, aluminum or fiberglass. Sliders cost more than double-hungs, and a bay or bow runs several thousand dollars apiece.

The table shows installed price per window, national average, with Low-E and argon glass. The low figure is basic build grade, the high figure is best grade.

Style	Vinyl	Wood	Aluminum	Fiberglass
Double-hung	$580-$770	$920-$1,110	$960-$1,150	$1,000-$1,190
Slider (2-lite)	$910-$1,100	$1,450-$1,640	$1,510-$1,700	$1,570-$1,750
Bay or bow	$3,360-$3,550	$5,190-$5,380	$5,390-$5,580	$5,590-$5,780

From there, the price moves with frame material, size and shape, the condition of the existing opening, grids, trim and local labor rates.

Vinyl Window Quality: Why the Cheap Ones Fail

Basic grade frames are screwed together at the corners instead of welded. Those joints loosen season after season, the sash drifts out of square, and the window starts sticking and leaking air. Seals, balances and locks are bargain parts too. Skip this tier.

Better grade has fusion-welded corners, better weatherstripping and sturdier hardware, though the vinyl walls are thinner and the frame chambers usually aren’t foam-filled. For most houses, this is the sweet spot.

Best grade means heavy welded frames, extra weatherstripping and sometimes triple-pane glass. It costs more and keeps working like new for decades.

Vinyl, Fiberglass or Wood: Which Is Worth It?

Vinyl isn’t automatically cheap. Premium lines like Pella’s 350 Series use heavier vinyl and offer triple-pane glass, and they can cost as much as entry-level wood.

Fiberglass is the priciest frame in our calculator, a step above wood, and makers like Marvin build high-end lines around it. Slim, stable frames suit contemporary homes.

Wood double-hungs start around $760 to $950 installed and pass $1,510 for upgraded units, while a wood bay runs $4,400 to $7,540. Species like mahogany or cherry cost more still. Andersen is the best-known name.

Honest take: a solid better-grade vinyl window gives most houses nearly all the performance for far less. Buy wood or fiberglass when the architecture calls for it.

What Does Window Installation Labor Cost?

Labor alone runs about $150 to $250 for a double-hung and $250 to $410 for a slider. Bays and bows run $1,070 to $1,830 just to install.

Those figures assume an insert job, where the new unit goes into the old frame. Tearing out to the studs and building a new frame can double labor, and rotted framing is repaired at extra cost. Crews on the West Coast and in the Northeast also tend to charge 10 to 25% more than crews in the South.

Get three bids and make sure each one says “insert” or “full-frame,” or you’re not comparing the same job. You can get free quotes from local window installers here.

Are New Windows Worth the Money?

How much will I save on energy?

Swapping drafty single-pane units for Low-E double-pane glass can trim a few hundred dollars a year from heating and cooling, more in harsh climates. Add attic insulation and the savings stack, and a tighter house may even get by with a smaller furnace next time.

Do new windows raise home value?

Some, but don’t expect every dollar back. Resale surveys usually put window replacement at roughly half to three-quarters of its cost recouped at sale. Buyers notice windows from the curb, right along with siding.

Should I replace them all at once?

If you can. Crews have fixed setup costs per visit, so one big job beats three small ones. On a tight budget, start with the draftiest side of the house and price each phase separately with the calculator above.
