What is the Siding Calculator?

The Siding Calculator is a user-friendly tool designed to assist homeowners, contractors, and builders in estimating the total amount of siding material required for a project. By inputting basic dimensions of the walls, windows, doors, and other structural features, users can figure out the necessary siding area and estimate costs based on their chosen materials.

How Does the Calculator Work?

The calculator uses a straightforward formula to calculate the net siding area:

\[ \text{Net Siding Area} = (\text{Wall Height} \times \text{Total Perimeter} \times \text{Number of Stories}) - (\text{Total Openings Area}) \]

\[ \text{Total Openings Area} = (\text{Windows Area}) + (\text{Doors Area}) + (\text{Garage Area}) \]

\[ \text{Total Siding Cost} = (\text{Net Siding Area} \times \text{Siding Cost per sq ft}) + (\text{Trim Cost}) + (\text{Insulation Cost}) + (\text{Installation Cost}) \]
