Building Material Calculator — bricks, cement, steel, sand and cost

This calculator turns a covered area into a practical shopping list for a house: bricks or concrete blocks, cement bags, steel bars, sand, crush, and the tiles and paint that appear once you move from grey structure to finishing. Enter the covered area of one floor, choose how many stories, pick brick or block masonry, set the finish level and the city, and the page estimates quantities and a planning cost range in PKR or AED.

The numbers are built from published construction planning ratios, not from a single magic formula. A 9-inch brick wall uses about 9 bricks per square foot of wall, a 4.5-inch wall about 4.5, and an 8-inch block wall about 1.05 to 1.125 blocks per square foot. For a whole house, the tool starts from grey-structure ratios per covered square foot and then adjusts for masonry type, number of stories, finishing and wastage. The result is deliberately labelled as an estimate: soil, spans, seismic detailing and the actual drawings can move steel and concrete significantly.

Location changes the money, not the physics. Labour, transport, cement and steel prices differ between Lahore, Karachi, Punjab cities, Dubai, Sharjah and Abu Dhabi. The calculator uses a dated planning rate for each city and shows a range around it. Replace it with a current contractor or supplier quotation before you commit a budget. The tool runs entirely in your browser, needs no upload and works on a phone.

The base column below is for a single-storey residential grey structure with brick masonry. The tool adjusts these figures for block walls, upper floors, finishing and the wastage you enter. They are planning ratios, not a substitute for a measured bill of quantities.

Cement is shown in 50 kg bags. Steel is shown in kilograms and converted to metric tons. Sand and crush are shown in cubic feet and approximate tons using bulk densities of about 45 kg/cft and 47 kg/cft.

Brick counts depend on the face that shows on the wall. A standard Pakistani brick is about 9 × 4.5 × 3 inches. With a 10 mm mortar joint, a 9-inch wall shows a 9 × 3 inch face and needs about 9 bricks per square foot; a 4.5-inch wall needs about half that. A 13.5-inch wall needs about 13.5 bricks per square foot.

Concrete blocks are larger, so the count is much lower. An 8 × 8 × 16 inch block covers about 0.89 sq ft without the joint, or roughly 1.05 to 1.125 blocks per square foot with mortar. The same face count applies to 4-inch, 6-inch and 8-inch blocks; the thickness changes the mortar volume and wall strength, not the face count.

The cost ranges below are planning assumptions reviewed for Q4 2026. They cover materials and labour for the stated scope, but exclude land, government approvals, utility connections, basement, boundary wall, landscaping, furniture and appliances. A contractor's quotation can be higher or lower depending on specification, access and the date of the quote.

Pakistan rates are in PKR per covered square foot; UAE rates are in AED per covered square foot. The calculator applies a storey factor for upper floors and then shows a range around the selected rate. Use the material quantities as the shopping list and the cost range as an early budget, not a final offer.

Grey structure is the unfinished shell: excavation and foundations, RCC columns, beams, slabs and staircase, brick or block masonry, internal and external plaster, and roof waterproofing. It usually excludes floor tiles, paint, doors, windows, electrical fittings, sanitary fixtures, kitchen cabinets and furniture.

Semi-finished adds a partial finishing allowance — typically basic flooring, plaster touch-ups and some paint — but not a full turnkey house. Complete finishing adds tiles, paint, doors and windows, basic electrical and sanitary fittings and a kitchen allowance. The exact scope must be written into the contract; two quotations with the same per-square-foot rate can include very different work.

Ask for the covered-area schedule by floor, the structural drawings and the masonry specification. Check whether the contract uses 4.5-inch, 9-inch or 13.5-inch walls, and whether the block size is 4, 6 or 8 inches. Confirm the cement bag weight (50 kg in Pakistan), steel grade and the wastage responsibility.

For a serious order, give the material list to two or three suppliers and compare delivered rates, not just the headline price. Cement, steel and bricks are bulky; transport can change the effective rate more than a small difference in the quoted unit price. Keep a contingency of 5–10% for changes and site waste.

• Covered area is not plot area. A 5 Marla plot is about 1,125 sq ft; the covered area of one floor is usually smaller after setbacks, stairs and open space.
• Order 5–10% extra bricks and blocks for breakage, cutting and corners. The calculator applies your wastage figure to the material totals.
• A 9-inch brick wall is about 9 bricks per sq ft of wall; a 4.5-inch wall about 4.5. Do not use the same count for both.
• For a normal residential grey structure, plan around 0.4–0.5 cement bags, 4–5 kg steel, 1.5–2 cft sand and 1.3–1.6 cft crush per covered sq ft. Long spans and heavy slabs can exceed this.
• Concrete blocks are faster and more uniform, but brick and block walls behave differently under load and heat. Let the structural engineer choose the wall type and thickness.
• The cost range excludes land, approvals, boundary wall, basement, furniture and appliances unless your contract says otherwise.
• Construction rates move. Replace the city rate with a dated local quotation before comparing contractors.
