About this calculator
The CUB/m² Calculator estimates the basic construction cost of a property. The Basic Unit Cost (CUB) is a Brazilian real estate indicator calculated by construction industry unions based on standard projects. The tool multiplies the total area (in m²) by the regional CUB value, providing an initial estimate of construction costs.
To use it, enter the desired built area and select the state and reference month. CUB varies by region and project type (standard residential, high standard, etc.). The calculator obtains updated values from official sources (such as SindusCon-SP) for each state. The result is a gross value, not considering land, projects, fees, or special finishes.
This calculator is useful for construction companies, developers, and owners who want a first approximation of the work cost. It also serves to compare budgets or check if a proposed value is within the market average. Keep in mind that CUB is a basic cost; the actual cost can be up to 30% higher depending on specifications and location.
Cautions: CUB does not include special foundations, elevators, central air conditioning systems, landscaping, or land. Additionally, the CUB for a given month may be adjusted due to inflation of materials and labor. For a precise budget, consult an engineer or developer.
Frequently asked questions
What is CUB and how is it calculated?
CUB stands for Basic Unit Cost. It is calculated by construction unions based on standard projects, considering materials, labor, and administrative expenses. The value is published monthly per state.
Does the CUB cost include the land?
No. CUB only considers building construction costs, excluding land, special foundations, architectural projects, and approval fees.
Can I use CUB for any type of construction?
CUB is defined for standard residential, commercial, and industrial projects. For very specific constructions, the actual cost may differ significantly. Consult a professional.
How often is CUB updated?
CUB is updated monthly by state unions. The calculator fetches the most recent values available for the selected month.
Is the calculator result the final price of the work?
No. The result is an estimate of the basic cost. The final cost may be higher due to finishes, special installations, specialized labor, and taxes.
