Pergola Footing and Concrete Calculator

Enter the post count and footing size to see cubic yards, bags of concrete and the depth to plan for.

These tools give planning-level estimates from typical values. They are not quotes, designs or engineering, and results depend on your actual materials, soil, site, local rules and conditions. Only a yard visit can confirm what a project needs, and we give you a written scope and price before any work begins.

How it works

Four quick steps.

  1. 01

    Set the post count

    Four, six, eight or more posts.

  2. 02

    Pick the footing size

    Diameter and depth of each hole.

  3. 03

    Read the concrete

    Cubic yards and bags to plan for.

  4. 04

    See the gravel and weight

    Base material and total weight.

Tips

  • Footings must go below frost depth, and local code sets the minimum.
  • Wider footings spread the load. Deeper footings resist wind and frost.
  • Call 811 before you dig so that utilities are located.
Questions

About this tool.

Is this an engineered design?

No. It is a volume calculator. Footing size depends on soil, loads and local code, and we coordinate engineering when needed.

How many bags is that?

The tool shows bags of premixed concrete in two common sizes.

How long until I can build?

Concrete usually cures for several days before it carries load.
