Staircase Concrete Calculator PRO Calculate staircase concrete volume, cement, sand, aggregate, water, steel and total construction cost. Number of Steps Tread / Step Length (m) Rise / Step Height (m) Width of Staircase (m) Waist Slab Thickness (m) Material Rates Cement Rate (₹ per bag) Sand Rate (₹ per m³) Aggregate Rate (₹ per m³) Steel Rate (₹ per kg) Calculate Complete Estimation Formula Used Stair Length = √[(Total Rise²) + (Total Tread²)] Concrete Volume = Length × Width × Thickness Dry Volume = Wet Volume × 1.54
