So you need to change your old windows – they’re broken, outdated or just worn out. But, as a smart shopper, you’d like to know the cost of replacement in advance.

Find out below how to calculate the approximate price you’ll have to pay.

What Makes Up Window Replacement Cost?

Not all window replacement cost is the same. However, there is a general formula that applies to the price of every installation.

Here it is:

Cost of Replacement = New Window (or Window Part) + Supplies + Labor + A Percentage for Profit .

Important To Know

How badly damaged is your window? This will determine what part you need to replace.

Changing only one window element will usually mean a lower cost for replacement. For instance, window glass replacement cost could run as much as 50 percent lower than the price to install a whole new window.

Why Is The Price Of Some Window Styles So High?

Some window styles (such as a bay window) may be more complex in design and require numerous panes – and unusual sized panes or custom shapes might have to be specially ordered. This would naturally raise your window glass replacement cost, in terms of both the material needed and the labor required to install it.

What Else Affects Window Replacement Cost?

You might be surprised! Price often varies according to:

• Height of the window. The average cost to replace windows on upper stories is generally more than on the ground floor. The reason? It’s harder for pros to access your top floor carrying heavy windows, tools and supplies.
• 
Location of your home. Window companies may charge more in wealthy urban centers – or in isolated locales that are out of their usual service area.

• Time of year. Window installers tend to be busiest in the warmer months – spring and summer are their peak season. As a result, customers may pay a premium price at these times.

How To Save Money On Cost Of Replacement

If you’d like to pay a lower price for the cost of replacement windows, choose your material carefully. A vinyl window, for example, will usually cost less than a wooden one.

Consider the time of year, as well. For non-emergency window replacement, book an appointment during the fall or winter. (Pros install windows one at a time, working quickly to minimize cold drafts coming into your home.)
