Deck Builder Calculator provides estimates for a simple rectangular deck project. Calculator functions include the following:
A deck, porch or just the floor under one's feet all have much in common. They need structural support and will need to be covered. This calculator is simple but useful in many applications. Decks can come in all shapes and sizes, but the most common is the simple rectangle with a width and length. For these calculators, the length is associated with the length of the independent joists. This length is also known as the joist span. Please consult your local building codes prior to building a deck to determine if the materials and construction method are adequate to accommodated the weight (load) that will be placed on the framing. Weight requirements can wildly vary. The most common object on decks that pose load challenges are hot tubs. These popular items contain large volumes of water that can literally weigh tons and pose dangerous loads on the deck structure.
When the width of your deck is longer than the length of your boards, splicing is required. If possible, you might want to consider longer boards if they are available. Longer boards will reduce or eliminate splicing which saves labor, and in some cases may even save material costs. For example, at the time of this writing, a nationally advertised provider of decking boards listed 5/4" thick, pressure treated, six inch wide deck boards that were $6.84 for 8' boards and $8.70 for 10' boards. In the graphic below, you can see where 10' boards only required 12 boards to cover the deck and 8' boards required 17 boards and 13 splices. In this case, the 10' boards ended up costing less at $104.40 verses $116.28.
Decking boards, the planks that make up the surface of a deck, can be constructed from a variety of materials. Each material has its own set of characteristics, including durability, appearance, maintenance requirements, and cost. Here are some common materials used for decking boards:
|Flooring Pricing Survey Data (U.S. dollars per square foot)|
The above prices are for different flooring materials and price points in the United States as advertised on the date indicated by a large big-box DIY retailer on their public website. A retailer is surveyed and the number of products included in the survey is listed. Survey sample is typically not the complete product line of the retailer. This is purely for convenience of calculator users to make a rough estimate. Sample pricing is entered into Price Survey Tools to generate the statistics found above.
CAUTION: The pricing information provided is for calculating convenience with NO implied guarantees to the accuracy of the values listed. Authoritative sources should be sought to confirm any value before risking health or wealth on the veracity of the data. Furthermore, vCalc gives no guarantee that you will be able to buy products at listed prices or even if they will be available. The data provided is purely a convenience for making estimates, so we strongly recommend that one ALWAYS use local pricing and authoritative specifications.
