Estimating Concrete Steps

Steps seem tricky to calculate but are not. If there are three steps leading up to a porch:

  • Use the slab calculator to figure the concrete needed for the porch surface.

  • Use the footing calculator to calculate the sides of the porch and the steps

Here is an example:

This porch has 9 sq. feet of porch surface, so enter in the slab calculator 4" thickness by 3' width by 3' length. This totals .11 cubic yards.
3' x 3' Porch

This porch has 9 sq. feet of porch surface, so enter in the slab calculator 4" thickness by 3' width by 3' length. This totals .11 cubic yards.

The porch also has 9 linear feet of 6" step. So enter in the footing calculator, 6" depth by 12" width (always figure steps with a 12" width) by 9' length. This totals .17 cubic yards.

The total concrete needed for the 3' by 3' porch will be .28 cubic yards. (.11 + .17 cubic yards = .28 cubic yards)

Repeat this for added layers of steps.
