Build your dream home, know every rupee.

Ask three contractors what your house will cost and you will get three answers

All three will be a lump sum, none will be itemised, and the one you accept will grow by 20–30% before the roof is on. Not because anyone lied — because "₹1,700 per square foot" is a rate for the structure, and a house is not only its structure. The lift, the borewell, the compound wall, the interiors, the sanction fees and the eight months of interest on the loan are all real, all excluded from that rate, and all yours.

This house construction cost calculator builds the estimate the way the site actually consumes money: floor by floor, at a rate that reflects your city and your finish quality, with every add-on priced separately, the material quantities worked out, the loan modelled and the rental income projected if you plan to let a floor.

Construction cost per square foot in India, by finish quality

The single most searched number in Indian home building, and the one most often quoted without its conditions. These are the rates the calculator uses for the structure, before city adjustment and before add-ons.

Notice the jump from Standard to Premium — a 53% increase for finishes, not for structure. The concrete, the steel and the labour are nearly identical in both. Almost everything above roughly ₹1,700 a square foot is finish, and finish is the part you can phase. Build the structure right the first time, because it is the part you cannot revisit; the marble can wait a year.

City multipliers — the same house costs differently in different places

Labour rates, material transport and local practice move the base rate substantially.

The construction spread from Agra to Mumbai is about 1.55×. The land spread is nearly 14×. If you already own the plot, building in a metro is far less punishing than the headline suggests — and if you do not, the land is the decision and the construction rate is a detail.

Floor by floor — why a G+2 is not three times a ground floor

Each additional floor costs less per square foot than the one below it. The foundation, the plinth, the sump, the septic tank and the main service runs are paid for once and carry the whole building.

Material quantities for an Indian RCC house

These are the standard consumption ratios per square foot of built-up area. They are what you use to check whether a contractor's material bill is plausible — the most useful thing on this page if somebody is buying material on your behalf.

Steel and cement together are typically 25–30% of the structural cost, and they are the two line items where substitution is most tempting and most damaging. Unbranded TMT bars save a few rupees a kilo and cost you the building's design life. Save on tiles, never on steel.

What the per-square-foot rate does not include

This is where the 20–30% overrun comes from. Every one of these is a real cost and none of them is inside the rate.

• Land, registration and stamp duty — usually the largest number in the whole project.
• Approvals — building plan sanction, development charges, water and electricity connections, completion certificate.
• Compound wall, gate and site levelling — priced separately, always needed.
• Borewell or water connection, and the sump — around ₹1,00,000 for a borewell with pump.
• Lift — roughly ₹9,00,000 for a two-stop hydraulic unit. Mandatory in some municipalities above a certain height.
• Solar — around ₹2,80,000 for a 5kW grid-tied system, subsidy-eligible under the national scheme.
• Interiors beyond the finish level — modular kitchen, wardrobes, false ceiling. Typically another 12% (basic) to 38% (luxury) on top of the structure cost.
• Loan interest during construction — a construction loan disburses in stages and charges pre-EMI interest from the first one.
• Contingency — keep 10%. Every site finds something.

How to use this construction cost calculator

1. Pick your city. It sets the cost multiplier and the indicative land rate. Choose Custom if you know your local rate.
2. Enter the plot area and select the floors you will build. Ground, first, second, third, basement and terrace are costed at their own multipliers.
3. Choose the finish quality. Standard is what most families build. The tab compares all five side by side on your own area.
4. Set the interior level. This is a percentage on top of the structure, from 12% for basic to 38% for luxury, and it is where budgets quietly double.
5. Tick the add-ons you actually need. Lift, solar, borewell, automation, servant room — each is priced individually rather than assumed.
6. Check the material quantities. Cement bags, steel kilos, bricks and sand — take this to the site and check what is being delivered.
7. Plan the loan and the rental income. If a floor will be let, the rental tab projects the income and the yield against the money you have put in.

Glossary

Built-up area

Floor area including the walls and balconies. Construction rates are quoted on this.

Carpet area

The usable area inside the walls — the only floor you can actually stand on.

Plinth

The raised base on which the house sits, above ground level and below the floor.

RCC

Reinforced Cement Concrete — the steel-and-concrete frame carrying the building.

TMT steel

Thermo-Mechanically Treated reinforcement bars. Fe500D is the usual grade for houses.

AAC block

Autoclaved Aerated Concrete — a lighter, better-insulating alternative to red brick.

M-sand

Manufactured sand from crushed stone. More consistent and better regulated than river sand.

FAR / FSI

Floor Area Ratio — how much built-up area your plot is legally permitted to carry.

Setback

The open space you must leave between the building and the plot boundary.

Completion certificate

The authority's confirmation that the house was built to the sanctioned plan.

Pre-EMI

Interest paid on the portion of a construction loan disbursed so far, before the full EMI begins.

Rental yield

Annual rent divided by the money invested. The test of whether a let-out floor was worth building.
