Cement Quantity Calculation Guide
One of the most common questions builders face is: "How many bags of cement do I need?" Over-ordering wastes money, while under-ordering causes project delays. Here is a practical guide to calculate cement requirements accurately.
General Thumb Rule
For a standard residential house, you need approximately 0.4 bags of cement per square foot of built-up area. So a 1000 sq.ft. house needs roughly 400 bags (50 kg each).
Detailed Breakdown
- Foundation (PCC + RCC): 0.08 bags/sq.ft.
- Columns & Beams: 0.12 bags/sq.ft.
- Slab: 0.10 bags/sq.ft.
- Brick Work: 0.05 bags/sq.ft.
- Plastering (Internal + External): 0.04 bags/sq.ft.
- Flooring: 0.01 bags/sq.ft.
Example: 1200 Sq.Ft. House
Total cement = 1200 x 0.4 = 480 bags approximately
Always add 5-10% extra for wastage, so order around 500-530 bags.
Grade Selection
- Foundation, Columns, Beams, Slab: Use OPC 53 Grade
- Brick Work, Plastering: Use OPC 43 or PPC
- Flooring & Tiling: Use PPC or White Cement
Cost Saving Tips

- Plan deliveries in phases to avoid storage issues
