Three tools in one: Quick BOQ cost estimate, IS-standard material consumption calculator, and CPWD productivity norms — all sourced from CPWD DSR 2021 and BIS standards.
Enter your project type and area to get a ball-park cost estimate based on current Indian market rates (Q3 2024). Not a substitute for a detailed BOQ — use as a first-cut sanity check.

Enter the type of work and quantity to get IS-standard material consumption figures including 5% wastage allowance (per CPWD DSR 2021).
| Material | Per Unit | Total (with 5% wastage) |
|---|
Source: CPWD DSR 2021 · IS 456:2000 · IS 383:2016 · Wastage factor: 5% added to all quantities.
Standard CPWD DSR 2021 labour productivity norms for common construction activities. Use these to plan manpower and compare your site's actual output.
How to use: If your activity quantity is 200m² of plastering and you have 8 masons, expected duration = (200 × 0.08 man-days) ÷ 8 = 2 days.

Every rate behind these estimators comes from CPWD DSR 2021 or a BIS material-consumption norm, not a rule of thumb — so a number you get here is defensible in front of a client or consultant.
