Enter the number of windows, cost per window, cost of additional installation materials, and labor cost into the calculator to determine the total cost of installing impact windows.

## Impact Window Formula

The following formula is used to calculate the total cost of installing impact windows.

TC = (N * C) + I + L

Variables:

- TC is the total cost of installing impact windows ($)
- N is the number of windows to be installed
- C is the cost per window (including the window itself and installation costs) ($)
- I is the cost of any additional installation materials needed ($)
- L is the labor cost for the installation ($)

To calculate the total cost of installing impact windows, multiply the number of windows to be installed by the cost per window. Then, add the cost of any additional installation materials needed and the labor cost for the installation.

## What is an Impact Window?

An impact window is a type of window specifically designed to withstand severe weather conditions, such as hurricanes and tropical storms. They are made from impact-resistant glass, which is composed of two layers of tempered glass bonded with a layer of a special material, typically polyvinic butyral (PVB). This construction allows the window to resist high winds and flying debris, and even if the glass is broken, the PVB layer holds the pieces together, preventing them from causing injury or damage. Impact windows are commonly used in coastal areas prone to severe weather.

## How to Calculate Impact Window?

The following steps outline how to calculate the Total Cost of installing Impact Windows.

- First, determine the number of windows to be installed (N).
- Next, determine the cost per window (C), including the window itself and installation costs.
- Next, determine the cost of any additional installation materials needed (I).
- Next, determine the labor cost for the installation (L).
- Finally, use the formula TC = (N * C) + I + L to calculate the Total Cost of installing Impact Windows.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

Number of windows to be installed (N) = 10

Cost per window (C) = $500

Cost of additional installation materials (I) = $100

Labor cost for the installation (L) = $200
