Why Calculators Matter More Than Ever in 2025
- Price roller-coaster: Cement prices dipped 2% year-on-year in March but could spike again as government spending ramps up.
- Wage hikes: The 2024 labour-wage revision pushed on-site labour to ₹140–200 per sq ft in big cities
- City gap: A square foot in Mumbai can cost twice one in Guwahati.
- Click-to-revise: Change room size or finish level; the calculator re-prices instantly.
- Loan timing: A realistic early estimate helps families lock construction loans before the next interest-rate hike.
