Response Times
We respond to all messages within 1–2 business days (Monday–Friday, 9:00 AM–6:00 PM IST). For construction estimate questions, please include:
- Your city or region
- Project type (residential / commercial / industrial)
- Built-up area in sq ft
- Number of floors
- The specific estimate output that seems incorrect
This helps us verify whether the discrepancy is within the normal ±10% variance range or indicates a data issue in our rate database for your region.
Help Us Improve Our Rate Data
Our construction cost calculator covers 600+ districts across India, and keeping regional rates accurate is an ongoing process. If you're a contractor, builder, or experienced homeowner who has found our estimates significantly off for your area, your feedback directly improves the tool for thousands of others.
What helpful feedback looks like:
- "In Coimbatore (semi-urban), standard construction is actually costing ₹1,700–1,900/sq ft currently, not ₹1,500."
- "TMT Fe-500D steel in Nagpur is ₹68/kg this month, your estimate seems to be using ₹62."
- "OPC 43 grade cement in Lucknow is ₹430/bag, not ₹395."
These data points are invaluable. Please use the contact form above or email us directly at contact@constructionestimatecalculator.in.
