Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Solid stair volume = width × tread depth × riser height × n(n + 1) ÷ 2. Landing volume is added, then the allowance is applied and bags are rounded up.
FAQ
Concrete Steps Calculator questions
Why does stair volume use a triangular series?+
Each tread segment supports a different concrete height. Adding those increasing step prisms produces the n(n + 1) ÷ 2 factor.
Does the calculator check stair-code geometry?+
No. Riser height, tread depth, landings, handrails and guards must meet the rules that apply to the project.
Are these steps assumed to be solid?+
Yes. Hollow, suspended or precast stair systems use different quantities and engineering.
