Building boundary wall fence posts for your plot in rural UP or Jaipur? Don’t let weak RCC posts crack, lean in windstorms, or pull out during rains—Construction Estimator India calculator gives you exact cement, sand & aggregate for bulletproof fence posts that last 30+ years.

Why Accurate Cement Calculation for Fence Posts Is Important?

Fence posts take wind load, cattle push, soil moisture—under-concreted posts = fallen fences, stolen crops, ₹20,000 rework. Over-ordering wastes ₹5,000–₹15,000 per 100 posts. Proper M20 concrete (8 bags/m³) ensures zero cracks, deep grip in black cotton soil. Construction Estimator India helps you save 20% material costs with perfect quantities.

Simple Cement Calculator Formula for Fence Posts (Step-by-Step)

Construction Estimator India dead-simple M20 formula:

1. Volume/post (m³) = 0.23 × 0.23 × Depth(m) (standard 9″x9″)
2. Dry volume = Wet volume × 1.54
3. Cement bags/post = Dry volume × 8 bags/m³
4. Sand/post = Dry volume × 14.5 cft/m³
5. Aggregate/post = Dry volume × 29 cft/m³

Example: 0.23×0.23×1.0m = 0.053 m³/post → 0.55 bags cement, 2 cft sand, 4 cft aggregate/post.

Total for N posts: Multiply by N + 10% wastage.
