How much cement, steel and sand a house needs in India (2026)

These figures are per sq ft of built-up area (BUA) for a low-rise RCC frame house on normal soil. They are for planning only. Your structural engineer's drawings and bar bending schedule give the real quantities.

• Floors. Each added floor puts more load on the columns and footings below, so steel per sq ft rises with height.
• Seismic zone. Delhi NCR, much of north India, the Himalaya and the north-east are in the higher seismic zones. The design code asks for more ductile detailing there, which means more steel at joints.
• Soil. Black cotton soil, filled land and soft coastal or alluvial soil can need deeper footings, a raft or piles. That adds concrete and steel below ground.
• Design. Long spans, cantilevered balconies, large openings and a basement all add steel. A plain, column-on-grid plan uses the least.
• Walls. AAC or fly ash blocks in place of red bricks cut mortar and the weight the frame carries.

So treat the table as a range to ask questions about, not a target. If a quantity is 30% away from it, ask the engineer or contractor why.

Established cement brands include UltraTech, ACC, Ambuja, Ramco and Dalmia. Common TMT brands include Tata Tiscon, JSW Neosteel and SAIL. A branded bar costs a little more than secondary steel, but its grade is more reliable. Whatever you buy, check for the BIS mark: IS 1786 for TMT bars, IS 269 for OPC and IS 1489 for PPC.

Sand is often sold by the ton or by the truckload, not by the cft. One tonne of sand is roughly 22 cft. River sand at ₹1,200–2,000 a tonne is about ₹55–90 per cft. M-sand at ₹900–1,500 a tonne is about ₹40–70.

Take a ground plus first floor house with 2,000 sq ft of built-up area. Using the calculator's rules, with wastage added, the quantities and costs come out like this.

Add a floor and the steel goes up. As a G+2 house of the same area, at 5.25 kg per sq ft, the steel is 10,920 kg with wastage, or ₹6.3–8.3 lakh. The total rises to about ₹12.5–17.9 lakh.

For scale, our rate table puts a standard house at about ₹1,800–2,450 per sq ft in most cities, so ₹36–49 lakh for this house. The five materials above are about a third of that. Labour, finishes, doors, windows, wiring and plumbing make up the rest.

• Ask the contractor for a bill of quantities (BOQ) that names the grade and brand of cement and steel, not just the quantity.
• Buy steel against the engineer's bar bending schedule, not a lump-sum tonnage.
• Weigh a sample bundle of steel at delivery, and check the brand and grade rolled onto the bars.
• Check the manufacturing date on cement bags. Use cement within about three months, and store it off the floor, away from damp.
• Check whether dealer rates include GST, cartage and unloading. They often don't.
• Don't skimp on curing. Cheaper cement used well beats good cement cured badly.

A structural engineer designs the frame and gives the bar bending schedule. That is where the real steel and concrete quantities come from. Your contractor then buys against it, and a local dealer supplies the cement, steel and aggregates. On a turnkey contract, ask to see the dealer bills for steel and cement.
