Enter the number of windows being installed and the total cost into the calculator to determine the cost per window.

Cost Per Window Formula

The following equation is used to calculate the Cost Per Window.

  • Where CPW is the cost per window ($/window)
  • TCI is the total cost of installation and windows ($)
  • W is the number of windows

To calculate the cost per window, divide the overall cost by the number of windows.

What is the Average Cost Per Window?

You can expect to pay anywhere from $200 to $900 for a new single-hung or double-hung wood window.

There are so many different factors that come into play when deciding on a price per window, such as the size, the type of window, and if you want a double or triple pane.

The actual price of the window will depend on many factors including:

  • The type and age of your current windows
  • Location (the further you are from a major city, the more it will cost to have your replacement windows installed)
  • Size and shape of the window (a custom-made window will be more expensive than standard stock sizes)
  • Style of the frame (vinyl sash replacement windows typically cost less than wood-clad frames).
  • The material used in the frame (aluminum is much less expensive than vinyl or wood).


What factors should I consider before replacing my windows?

Before replacing your windows, consider factors such as the condition and age of your current windows, energy efficiency needs, the architectural style of your home, local climate, and your budget. These factors will help determine the type of windows that are best for your home and the overall cost of the replacement project.

How can I calculate the cost of replacing multiple windows in my home?

To calculate the cost of replacing multiple windows, you can use the Cost Per Window formula: divide the total cost of installation (including the cost of the windows themselves) by the number of windows you plan to replace. This will give you an average cost per window, helping you budget for the entire project.

Are there any ways to reduce the cost of window replacement?

Yes, there are several ways to reduce the cost of window replacement. These include choosing more cost-effective materials, such as vinyl instead of wood, opting for standard sizes and styles rather than custom options, and looking for rebates or tax credits for energy-efficient window installations. Additionally, comparing quotes from multiple contractors can help ensure you get the best price for the installation.
