Estimate window replacement by count, style, frame material and glazing, with removal and disposal included.
Quick answer: Eight windows at a typical $650 each works out to about $5,200 of base installed cost. Style, frame material and glazing each adjust that figure, and removal adds a typical $300. A 10% contingency puts the planning figure near $6,050 for a straightforward double-hung job.

What is Window Replacement Cost Calculator?
Window replacement is priced per window rather than per square foot, because most of the work — removing the old unit, flashing the opening, insulating and trimming — is the same whether the window is small or large. The installed price covers the unit plus labor, and it swings widely with frame material and glazing. Vinyl double-hung windows sit at the low end, wood and fiberglass at the high end, and bay or bow windows cost several times a standard unit because they combine multiple sashes in one opening. This calculator multiplies the number of windows by a price you control, then adds removal, a contingency and any permit your area requires.

The unit price and the installed price are different numbers
Advertised window prices are usually for the unit alone, sometimes not even glazed. The installed price includes labor, flashing, shims, insulation, interior and exterior trim, sealant and disposal of the old window. That gap is large enough that a quote built from showroom prices alone will look unrealistically low. The unit price in this calculator is the installed figure, which is what you should compare quotes against.
Frame material decides most of the spread
Vinyl is the cheapest common choice and needs little maintenance. Aluminum is slim and strong but conducts heat. Wood looks traditional and can be repainted, though it needs more care. Fiberglass sits between wood and vinyl on cost, holds its shape well and tolerates temperature swings. Because the frame is most of the unit cost, changing material moves the total more than any other single selection.
Glazing, style and installation conditions
Double glazing is the baseline in most of the country; triple glazing adds insulating value and often sound control at a higher price. Style matters too, because casement, picture and bay windows use different hardware and framing, and a bay replaces structure as well as a window. Finally, access: second-storey work, stucco or brick openings and lead paint in older homes all add labor.
Frequently Asked Questions
How much does window replacement cost per window?
Typical installed prices run from about $250 for a basic vinyl unit to $1,200 or more for a large wood or fiberglass window. The unit itself is usually the larger share, but labor, flashing, trim and disposal add up, and second-storey or hard-to-reach openings cost more.
Is it worth replacing all the windows at once?
Doing the whole house in one job usually costs less per window because setup, disposal and scaffolding are shared, and it keeps the exterior trim consistent. If the budget will not stretch, replacing the worst-performing windows first is a reasonable staged approach.
What is the difference between full-frame and pocket replacement?
A pocket, or insert, replacement fits a new sash into the existing frame and is faster and cheaper. A full-frame replacement removes the frame and trim to the rough opening, which allows better insulation and repair of rot, but costs more and usually disturbs interior and exterior finishes.
Do I need a permit for new windows?
Requirements vary by city and by whether the opening size changes. Like-for-like replacements often need no permit, while enlarging an opening or changing egress windows usually does. Check with your local building department, and remember that egress rules matter in bedrooms.
How much do triple-pane windows add?
Triple glazing typically adds a noticeable premium per window over double glazing, and the calculator applies an editable multiplier for it. In mild climates the energy saving may not repay the extra cost, while in very cold or very noisy locations the comfort gain is often what justifies it.
