Formula and assumptions
The estimate treats each step as a rectangular tread/riser block with overlapping geometry simplified as a stair-step prism. Confirm the shape and formwork with a qualified contractor.
Understand the geometry
The stair shape is not always a set of separate rectangular blocks; the concrete may be poured as a continuous stair profile. This estimate uses a simplified stepped-prism method and should be treated as approximate. Complex stairs, side walls, stringers, and landings need separate measurement.
Before ordering
Check the full form dimensions, rise/run layout, landing, reinforcement, and any structural plans. Do not use this estimate as a construction drawing.
Frequently asked questions
Are the prices current NYC contractor prices?
No. Prices are user-editable examples and are not presented as current market rates or a contractor quote.
Should I order exactly the calculated quantity?
Not without checking site conditions, measurements, product yield, supplier ordering increments, and the shape of the pour. Use the result as a planning estimate.
Can this calculator confirm NYC code compliance?
No. Confirm applicable requirements, permits, inspections, and design details with the relevant authority or a qualified professional.
