Brazil House Construction Cost Calculator (2026)
Data verified on
Enter the built area and finish standard to estimate what it costs to build a house in Brazil in 2026. The calculator uses the CUB — Brazil’s official construction cost index per square meter — for the July 2026 reference month, and shows both ends of the budget: the strict CUB figure and a realistic estimate that adds the 20–40% of items the index deliberately leaves out.
What the CUB index is and who publishes it
The CUB (Custo Unitário Básico, or Basic Unit Cost) is Brazil’s official construction cost per square meter. It was created by Federal Law 4,591/1964 and is calculated under technical standard ABNT NBR 12,721:2006, which defines reference "standard projects": R-1 for a single-family house, R-8 and R-16 for 8- and 16-storey residential buildings, and several others. Each comes in three finish standards — low (B), normal (N) and high (A).
Crucially, the CUB is not published by the federal government. Each state’s Sinduscon (the construction industry union) surveys material, labor and administrative prices in its own region every month and publishes a local index. That makes the CUB regional, and it is released by the 5th day of the following month — so in August 2026 the newest table available is the July 2026 reference.
This calculator is built on the São Paulo R-1 standard projects, the benchmark most widely used for residential budgets in Brazil’s largest construction market.
2026 CUB values by finish standard
Figures below are R-1 single-family standard projects for the July 2026 reference month. São Paulo and Rio Grande do Sul are shown on the standard payroll-charges table; Santa Catarina is on the "desonerado" table (reduced payroll contribution regime), which is what the local union publishes.
| Finish standard | Standard project | São Paulo | Rio Grande do Sul | Santa Catarina |
|---|---|---|---|---|
| Low / entry-level | R1-B | R$2,186.73/m² | R$2,557.10/m² | R$2,657.23/m² |
| Normal / mid-range | R1-N | R$2,681.61/m² | R$3,433.48/m² | R$3,147.03/m² |
| High / premium | R1-A | R$3,242.79/m² | R$4,632.89/m² | R$3,864.04/m² |
Why real cost always exceeds the CUB
The CUB is not the total cost of a build, and the technical note printed on every CUB table says so explicitly. Under NBR 12,721:2006 the index excludes foundations, retaining walls, tie-backs and water-table lowering; lifts; equipment such as water heaters, pumps, air conditioning and ventilation; playgrounds; complementary works; site urbanization, swimming pools, sports courts and landscaping; taxes, fees and notary charges; architectural, structural, services and special design fees; and the builder’s and developer’s own markup.
That list is long and expensive. Foundations alone can exceed 10% of a build, and design fees typically run 3–8%. Practising engineers therefore add 20–40% on top of the CUB to reach a realistic figure. This calculator uses 30%, the midpoint, and displays both numbers side by side. For a 120 m² normal-standard house in São Paulo that is the difference between R$321,793.20 and R$418,331.16 — roughly R$100,000.
Sites with steep slopes, poor soil or piling requirements sit closer to the 40% end of the range.
Where the money goes, stage by stage
Knowing the total is not enough — cash flow is what stalls Brazilian self-builds. The reference breakdown below sits inside the usual budget ranges for residential work and is what the calculator applies to your chosen figure. The headline finding: finishes are by far the largest slice, at roughly 37% — more than double the structure. Tiles, flooring, doors, windows, sanitary ware and paint are where budgets overrun, because each individual upgrade is multiplied across every room.
| Construction stage | % of total | 120 m² normal standard (with +30%) |
|---|---|---|
| Site preparation and foundation | 15% | R$62,749.67 |
| Concrete and steel structure | 16% | R$66,932.99 |
| Masonry and partitions | 10% | R$41,833.12 |
| Roof framing and tiles | 8% | R$33,466.49 |
| Electrical and plumbing | 14% | R$58,566.36 |
| Finishes, joinery and painting | 37% | R$154,782.53 |
| Total | 100% | R$418,331.16 |
Cost by house size: 40 m² to 200 m²
Nobody really wants a price per square meter — they want the price of their house. The table applies the July 2026 São Paulo CUB to nine built areas across the three finish standards, with the 30% of items NBR 12,721 excludes already added. The "index only" column is there deliberately: it is the figure most articles quote, and the gap to the realistic column is what typically runs out mid-build.
In the sizes people ask about most: a 60 m² house at normal standard lands at R$209,166 realistically, against R$160,897 on the raw index. A 100 m² house comes to R$348,609 and a 150 m² house to R$522,914. That same 100 m² house drops to R$284,275 at low standard and rises to R$421,563 at high standard — the finish choice moves the budget more than an extra 40 m² of floor area does.
One caveat on reading the table: the CUB is linear by construction, so a 50 m² house appears to cost exactly half of a 100 m² one. Real builds do not behave that way. Kitchens, bathrooms and laundry rooms concentrate the expensive work — plumbing, wiring, tiling, sanitary ware and fittings — and they do not shrink in proportion with bedrooms and living areas. Small houses therefore tend to run above the index per square meter, and large ones below it. We apply no correction factor because no technical source quantifies one, but keep the skew in mind below about 60 m².
| Built area | Index only (normal) | Realistic — low | Realistic — normal | Realistic — high |
|---|---|---|---|---|
| 40 m² | R$107,264 | R$113,710 | R$139,444 | R$168,625 |
| 50 m² | R$134,081 | R$142,137 | R$174,305 | R$210,781 |
| 60 m² | R$160,897 | R$170,565 | R$209,166 | R$252,938 |
| 70 m² | R$187,713 | R$198,992 | R$244,027 | R$295,094 |
| 80 m² | R$214,529 | R$227,420 | R$278,887 | R$337,250 |
| 100 m² | R$268,161 | R$284,275 | R$348,609 | R$421,563 |
| 120 m² | R$321,793 | R$341,130 | R$418,331 | R$505,875 |
| 150 m² | R$402,242 | R$426,412 | R$522,914 | R$632,344 |
| 200 m² | R$536,322 | R$568,550 | R$697,219 | R$843,125 |
Frequently asked questions
What does it cost to build a house in Brazil in 2026?
Using the July 2026 São Paulo CUB, construction costs R$2,186.73/m² at low standard, R$2,681.61/m² at normal standard and R$3,242.79/m² at high standard. A 120 m² normal-standard house comes to R$321,793.20 on the raw index and around R$418,331.16 once the 30% of excluded items is added — about R$3,486.09 per built square meter.
What does a 100 m² house cost to build in Brazil?
On the July 2026 São Paulo CUB, a 100 m² single-storey house at normal standard is R$268,161 on the raw index and roughly R$348,609 once the 30% of excluded items is added — foundations, design fees, permits, utility connections and the builder’s markup. Low standard comes to R$284,275 and high standard to R$421,563. The index is regional and revised monthly, so use the one published for your state.
Does the CUB include the land?
No. The CUB covers only the construction of the standard project. Land, transfer tax, registration, foundations, design fees, municipal permits, utility connections, walls, gates and landscaping are all excluded by NBR 12,721:2006.
Why do CUB values differ between states?
Each state union runs its own monthly price survey. In July 2026 the R1-N standard was R$2,681.61/m² in São Paulo but R$3,433.48/m² in Rio Grande do Sul. Always use the index published for the state where you will build.
Is a two-storey house more expensive per square meter?
Not necessarily, and no reliable public source quantifies an uplift — so this calculator applies no multiplier. NBR 12,721 has no two-storey standard project at all. Notably, the July 2026 São Paulo CUB prices an 8-storey building (R8-N) at R$2,231.37/m², about 17% below the single-storey R1-N, because foundations and roofing are spread across more floor area.

The index is regional and updated monthly, and real costs depend on soil, topography, design and suppliers.
