This Microsoft Excel-based calculator compares the costs of building a new deck with recycled plastic, recycled wood/plastic composite lumber, cedar/redwood, and pressure-treated yellow pine. Based on the size of the project, the calculator estimates the initial, 3-year, 6-year, 10-year, lifetime, and average annual costs for each of these common decking materials. Costs include maintenance, and waste disposal. Users have the option to input their own cost information.
