House Construction Cost Calculator (India)

Built-up area is multiplied by the number of floors, then by a city-specific rate band in rupees per square foot rather than a single national average — construction in Mumbai and in Nagpur do not cost the same thing, and a national figure is useless to both.

Each floor above ground carries a 2% escalation, because material has to be lifted and the structure below must be sized for the additional load. The calculator blends this across all floors rather than applying it flat.

The rate band is set by specification level, which moves the total far more than area does: a luxury specification can cost double a basic one on an identical footprint. The four tiers describe real material choices, not vague adjectives.

The result is split across the nine standard work heads by their typical share of a turnkey residential job. Those proportions are far more stable across cities and years than the absolute rates, so they are the most reliable part of the estimate and the best way to sanity-check a builder quote.

Rates exclude land, statutory approvals, GST and loose furniture. Last reviewed 2026-10-21; reviewed again quarterly because steel and cement move within months.
