Construction Material & Cost Calculator

For a standard 9-inch thick wall of 100 sq ft, you will need approximately 900 to 1,000 bricks. For a 4.5-inch thick single-brick partition wall of 100 sq ft, the quantity required is about 450 to 500 bricks. These figures include standard mortar spacing and a 10% wastage buffer.

A standard 10x12 room with a height of 10 feet typically requires around 80 to 95 bags of cement. This includes cement required for the brickwork mortar, double-layer wall plastering, foundation plinth, and concrete roof slab casting. Adding a wastage allowance of 10-15% ensures coverage for site discrepancies.

To calculate construction material quantities, determine the volume of excavation, brickwork, and concrete structures. Brick counts are computed based on total wall volume divided by single brick size with mortar. Cement, sand, and aggregate bags are derived using volumetric wet-mix ratios, plaster surface areas, and standard coverage coefficients.

In 2025, the average cost to construct a single standard room (10x12 feet) in India ranges from ₹1.2 Lakhs to ₹2.5 Lakhs. The budget depends on material grades (Basic, Standard, or Premium), current steel and cement commodity prices, and labor rates in your city (e.g. Mumbai and Bangalore carry higher costs).

A standard 50-foot boundary wall with a height of 6 feet (9-inch thickness) requires approximately 18 to 22 bags of cement for brick mortar and pillar concrete. If plastering both sides of the boundary wall is also required, you will need an additional 15 to 18 bags of cement.

To calculate bathroom floor tiles, multiply the floor length by width to get total square footage. For wall tiles, calculate the room's perimeter (2 x (Length + Width)), multiply by desired tile height (standard is 7 feet), and subtract the door opening area. Add a 10-12% buffer for cutting waste.
