A complete project-level estimate of bricks, cement, sand, aggregate, and steel from your built-up area and wall type, plus an overall cost breakdown. Adjust the per-sq.ft rates below to match your local practice and prices.
These are rough thumb-rule multipliers per sq.ft of built-up area — actual requirement depends on wall thickness, mix design, brick size, site conditions, and local practice. Adjust to match your project.
How to Use This Calculator
Enter your built-up area, number of floors, and wall type.
Toggle flooring and paint on or off, and open "Advanced" to adjust the per-sq.ft rates to match your project and local prices.
Click "Calculate" for an estimated material list and total project cost.
How the Estimate Is Built
The estimator first finds the total area: built-up area × number of floors. Each material quantity is that total area multiplied by a per-sq.ft factor from the Advanced panel, and each cost is the quantity multiplied by its rate. Labour is total area × labour rate per sq.ft. Flooring and paint are added only when their switches are on.
Choosing a wall type only changes the bricks factor: 8 bricks per sq.ft for 9-inch walls and 5 for 4.5-inch walls. "Custom" keeps whatever value is in the bricks field so you can type your own.
Example with the Default Settings
A single-floor, 1,500 sq.ft house with 9-inch walls, flooring and paint included, using the default factors and rates:

Material cost comes to ₹11,04,000 and the overall figure works out to about ₹986 per sq.ft. Steel, labour and cement together make up roughly two-thirds of the total, so the rates you enter for those three matter far more than the others. Doubling the floors to two doubles every quantity and cost.
Matching the Units Your Supplier Uses
Sand and aggregate are sold by the brass in Maharashtra and some nearby states. One brass is 100 cu.ft, so 2,250 cu.ft of sand is 22.5 brass. Elsewhere they may be sold by the tonne or by the truckload; ask the supplier how many cu.ft a load holds.
Steel is priced per kg or per tonne. 6,000 kg is 6 tonnes, and quotes are usually separate for each bar diameter.
Cement comes in 50 kg bags, so 600 bags is 30 tonnes.
Enter rates as the price you actually pay at site, including GST and transport. GST rates for building materials were revised on 22 September 2025; cement, for example, moved from 28% to 18%. Check current rates on the CBIC GST portal or with your supplier.
Costs This Estimate Leaves Out
The total covers the structure, masonry, basic flooring and paint. A finished house also needs doors and windows, electrical wiring and fittings, plumbing and sanitaryware, waterproofing, a kitchen platform, an overhead tank, and often a compound wall and gate. Plan approval fees, utility connections, soil testing and an architect or engineer's fees are extra as well. Keep a separate budget line for these, along with a contingency for price rises during construction.
Frequently Asked Questions
This gives a rough, project-level estimate using per-sq.ft thumb rules, not a detailed bill of quantities. Actual material needs depend on wall thickness, mix design, brick dimensions, mortar joints, wastage, site conditions, structural design, and local construction practices.
There's no single universal conversion factor for material use per sq.ft — it varies by region, builder practice, and design. The defaults are common rough estimates; adjust them if you have better figures for your project.
The calculator multiplies one area by the number of floors, so it assumes every floor is the same. If the floors differ, add their built-up areas together, enter the sum as the area and set floors to 1.
No. It covers bricks, cement, sand, aggregate, steel, optional tiles and paint, and labour at a per-sq.ft rate. Fittings and finishes such as wiring, plumbing, sanitaryware, doors, windows and waterproofing need to be budgeted separately.
With the default settings, steel, labour and cement account for about two-thirds of the estimate. Getting current local prices for steel per kg, cement per bag and the labour rate per sq.ft will improve the result more than fine-tuning paint or aggregate.
