Concrete Steps Calculator – Estimate Yards Needed for Concrete Stairs
Find the amount of concrete needed to pour steps. The calculator also supports a platform at the top of the steps, leave this empty to use the run dimension for the top step.

How to Estimate Concrete for Steps
Estimating concrete needed for steps may seem daunting, but it can be done in a few simple steps.
Divide the Steps into Rectangles
The first step to estimate the volume of a set of steps is to divide the steps into smaller rectangles. Finding the volume of a rectangular prism is much easier than finding the volume of a complex shape. Think about each step as a rectangle from the top of the step to the ground and the platform as a single rectangle.
Find the dimensions of each rectangle and measure the volume for them separately. Use our concrete calculator to assist in this process.
The dimensions of each rectangle will be the run by the vertical rise from the ground. To find this for each step simply multiply the rise of the step by the number of steps in it is. For instance, the first step is rise × run × 1, the second step is rise × run × 2, and so on.
The dimensions of the platform can be found by multiplying the platform depth by the height of the platform from the ground.
Find the Volume of Each Rectangle Section
The dimensions of each rectangle can be used to find the volume of each using the formula for volume, length × width × height. Simply multiply the step width by the depth and height for each rectangle section.
Find the Total Step Volume
The final step is to add the volumes of each step section together to get the total volume of the steps. Our concrete step volume calculator can help find how much concrete you need to pour your steps. If you’re feeling intimidated by the process you can also hire a professional contractor to measure and pour your steps.
