House Construction Cost Calculator

How the estimate works

The construction industry in India prices residential building on a per-square-foot basis covering both material and labour. Multiply your total built-up area by that rate and you have a workable ballpark. This calculator does exactly that, with three quality tiers you can override with your own contractor's rate.

What the three quality tiers mean

Typical cost split

Roughly a third of a residential budget goes on cement, steel and sand; a quarter on labour; and the balance on bricks, finishing, tiles, plumbing, electricals and professional fees. The breakdown shown with your result uses this industry-standard split, so you can sanity-check a contractor's quotation head by head.

Costs this estimate excludes

• Land cost, and stamp duty or registration on the land purchase
• Municipal plan approval, development charges and utility connection deposits
• Architect and structural consultant fees, if billed separately
• Compound wall, gate, driveway, borewell and landscaping
• GST, where your contractor charges it separately
• Loose furniture, appliances and soft furnishings

Keep a contingency

Set aside 10–15% of the estimate for the unexpected: rock excavation, design changes mid-build, material price rises, or a monsoon that stalls work. Projects that run over budget usually do so because no contingency was planned, not because the original estimate was wildly wrong.
