Floor Truss Cost Calculator

When planning a construction project, it’s essential to have a clear understanding of the costs involved. Floor trusses are a crucial component of many building projects, and their cost can vary significantly depending on various factors. To simplify the process of estimating the cost of floor trusses, we have developed the Floor Truss Cost Calculator. This handy tool allows you to quickly determine the estimated cost of floor trusses based on key parameters.

Formula: The formula used by our calculator to estimate the cost of floor trusses is as follows: Estimated Cost = (Span Length × Truss Depth × Truss Spacing × Load Capacity) / 1000

How to Use:

  1. Enter the Span Length (in feet) of the floor trusses you plan to use.
  2. Input the Truss Depth (in inches).
  3. Specify the Truss Spacing (in feet).
  4. Enter the Load Capacity (in pounds per square foot) that the floor trusses need to support.
  5. Click the “Calculate” button.
  6. The estimated cost of the floor trusses will be displayed in the “Estimated Cost” field.

Example: Let’s say you are designing a building with floor trusses that have a span length of 30 feet, a truss depth of 14 inches, a truss spacing of 2 feet, and a load capacity of 40 lbs/ft². Using the Floor Truss Cost Calculator, the estimated cost would be calculated as follows: Estimated Cost = (30 × 14 × 2 × 40) / 1000 = $33.60


  1. What factors can affect the cost of floor trusses?
    • Several factors can influence the cost, including span length, truss depth, truss spacing, and load capacity.
  2. Is this calculator suitable for residential and commercial projects?
    • Yes, it can be used for both residential and commercial construction projects.
  3. Can I change the units of measurement (e.g., meters instead of feet)?
    • Currently, the calculator only supports feet and inches for span length and truss depth. However, you can convert your measurements before inputting them.
  4. Are there any specific load capacity requirements I should be aware of?
    • Load capacity requirements can vary depending on local building codes and project specifications. Consult with a structural engineer for guidance.
  5. What’s the significance of the “/ 1000” in the formula?
    • This is a conversion factor used to ensure the result is in dollars rather than thousands of dollars.

Conclusion: Estimating the cost of floor trusses is an important step in any construction project. Our Floor Truss Cost Calculator simplifies this process, providing you with a quick and accurate estimate based on key parameters. By using this tool, you can make informed decisions about your construction budget and ensure the success of your project.
