Concrete Steps Calculator

Calculate the volume and weight of concrete needed for steps and staircases. Enter the width, run, rise, and number of steps to get results in cubic yards, bags, and ready-mix truckloads. Ordering slightly more than the calculated amount helps ensure you have enough for the full pour.

Estimating notes

  • Confirm local codes for maximum riser height and minimum tread depth.
  • Add waste—stairs often require extra due to form adjustments.
  • If your steps include side stringers or thickened edges, add that volume separately.
  • Bag yields and density vary by product; verify values on your bag or supplier spec sheet.
  • Cost estimates exclude delivery fees, taxes, and minimum loads.
