Cement, steel and brick quantities for your build

This construction material calculator works out how much cement, steel, brick, sand and crush a grey-structure build needs for your covered area, using 2026 Pakistan rates and a built-in wastage allowance. Enter the total constructed area across all floors and the quantities and material cost update live — a fast way to plan procurement and check a supplier's quantities.

How the quantities are derived

Each material is estimated from a per-square-foot coefficient applied to your covered area, then a wastage allowance is added on top. As a rule of thumb for a standard grey structure, budget around 0.4 bags of cement, 3.2 kg of steel and 8.5 bricks per square foot of covered area, plus sand and crush for concrete and mortar. These are planning coefficients for a typical residential build; a heavily reinforced design, a basement or long spans will use more steel and concrete, so treat the output as a procurement guide rather than a structural take-off.

Why a wastage allowance matters

Real sites never use exactly the theoretical quantity. Cement is lost to spillage and over-rich mixes, steel to offcuts and laps, bricks to breakage in handling. The calculator adds a standard wastage allowance so your order reflects what actually gets consumed, not the paper minimum. On cut and brittle materials it is always cheaper to order a small margin up front than to place an urgent top-up order mid-pour at a worse rate. For steel and cement especially, buying the bulk of the requirement in one go also protects you from price movement during the build.

From quantities to a delivered order

Heavy materials — sand, crush and bricks — carry a large transport share, so the delivered price depends heavily on your distance from the source; the city selector adjusts the estimate for that. Once you have your quantities, send them to us on WhatsApp for current delivered rates. While we specialise in finishing materials, we can point you to reliable grey-structure suppliers and help you sequence the finishing once the structure is up. For finishing quantities, use the full construction cost calculator instead.

As a planning rule for a standard grey structure, budget roughly 0.4 bags of cement, 3.2 kg of steel and 8.5 bricks per square foot of covered area, plus sand and crush for concrete and mortar. Heavily reinforced designs, basements or long spans use more. The calculator adds a wastage allowance on top.

Yes. A standard wastage allowance is added to every quantity to reflect real-site losses — cement spillage, steel offcuts and laps, brick breakage. This means your order matches what actually gets consumed rather than the theoretical minimum, so you are less likely to run short mid-build.

They are planning estimates from typical residential coefficients, good for procurement and for checking a supplier's quantities. They are not a substitute for a structural engineer's bar-bending schedule and concrete take-off, which account for your specific reinforcement and design. Use the output as a guide and confirm critical quantities with your engineer.

Sand, crush and bricks are heavy and carry a large transport cost, so their delivered price depends on how far you are from the source. The city selector adjusts the estimate to reflect typical delivered rates in each city rather than ex-quarry prices.

We specialise in finishing materials — wall panels, flooring, ceilings and MDF/HPL — rather than grey-structure materials. Use this calculator to plan your cement, steel and brick quantities, and talk to us for the finishing stage. Send your quantities on WhatsApp and we'll help you sequence the build.
