Construction Material Cost Calculator
Calculate the total cost of key construction materials including concrete, steel, and bricks for your building project.
Fill in the fields above and click Calculate to see your results.
How to use
Enter the quantities of the three structural materials — concrete volume in m³, steel weight in kg, and brick count — together with your current local unit prices. The calculator totals each material and gives the combined structural material budget.
Get quantities from your engineer's bill of materials if you have one. For a rough check, standard norms help: residential builds use roughly 100–120kg of rebar per m³ of concrete, and about 55–60 standard bricks per m² of 110mm wall. Prices for steel and cement move with the market, so re-quote within two weeks of purchase and add 3–5% to brick and concrete quantities for cutting waste and breakage.

Examples
Small residential house structure
- Steel / Rebar Weight:5,000
- Brick Quantity:10,000
- Concrete Volume:50
- Steel Price Per kg:18,000
- Brick Price Per Unit:2,500
- Concrete Price Per m³:1,800,000
Result
- Brick Cost:25,000,000
- Steel / Rebar Cost:90,000,000
- Concrete Cost:90,000,000
- Total Material Cost:205,000,000
Concrete and steel each cost 90M₫ and dominate the 205M₫ structural budget. The steel ratio here (100kg/m³ of concrete) matches residential norms — if your quote shows far less steel, question the structural design rather than celebrating the saving.
Single-room extension
- Steel / Rebar Weight:2,400
- Brick Quantity:6,000
- Concrete Volume:20
- Steel Price Per kg:18,000
- Brick Price Per Unit:2,200
- Concrete Price Per m³:1,800,000
Result
- Brick Cost:13,200,000
- Steel / Rebar Cost:43,200,000
- Concrete Cost:36,000,000
- Total Material Cost:92,400,000
A modest extension still needs 92.4M₫ of structural materials. Note steel exceeds concrete cost here — typical for small jobs where tie-ins to the existing structure demand extra reinforcement. Add 3–5% waste allowance on top before ordering.
Industry Benchmarks
| Metric | Typical Range |
|---|---|
| Sanity check: residential builds need ~100–120kg of rebar per m³ of concrete. A quote far below this range deserves a structural review. | — |
| Structural materials typically account for 60–70% of rough-build cost; labor takes the rest. Steel alone is usually 20–30% of the material budget. | — |
