How to Use This Calculator
Enter the total rise (height from bottom to top of steps) in inches, step width, and tread depth. Choose auto-calculate to let the tool determine the number of steps based on IRC maximum riser height, or enter the number of steps manually. Add cheek walls and a top landing if needed. The calculator computes concrete volume with a 10% waste factor.
Formula Used
Riser Height = Total Rise / Number of Steps. Total Run = (Steps - 1) x Tread Depth. Concrete Volume = sum of each step section (Width x Tread x cumulative height) + cheek walls + landing. Cubic Yards = Cu Ft / 27. IRC limits: max riser 7.75 in, min tread 10 in.
