How to Use This Calculator

- Select your preferred lumber material: cedar for longevity, pine for budget, composite for low maintenance, or pressure-treated for durability.
- Review the Estimated Total Cost, which combines lumber, corner posts, hardware, and bulk soil costs.
- Use the Lumber Needed (linear ft) and Total Boards count to create your shopping list at the lumber yard.
- Note the Soil Needed (cu ft and cu yd) to order bulk soil or calculate how many bagged mixes to buy.
- Check the Deck Screws count and Corner Posts needed to ensure you have all hardware on hand before building.
