Concrete Calculators
how much concrete do i need?

Calculate concrete cubic yardage for slabs, walls, footings, columns, stairs, blocks, curbs, and gutters using the many different concrete calculators on this page.

Estimate the volume and weight of concrete you'll need for any given area.

Figure out how many cubic yards of concrete you need in both US units of measure (feet and inches) and International system of units or metric units (meters and centimeters) of measurement.

The best way (and fastest way) to calculate concrete yardage is using a concrete calculator.

These concrete calculators are very accurate and will help you determine the volume of concrete you need for the type of project you're doing.

Always add a little extra to the quantity estimated just to be on the safe side.

Rarely is any concrete project perfect and you don't want to be left short on the amount you need.

You'll be able to calculate concrete cubic yardage, weight, and how many bags you need for:

Concrete slabs
Concrete Walls
Concrete Footings
Circular slabs or Tubes
Columns or Sono-tubes
Concrete Curbs and Gutters
Concrete stairs

Concrete calculator formula for a slab or floor

If you want to use a formula to calculate concrete volume, I have a whole page like the picture above that shows you a written formula for:

Square or Rectangular Slabs
Round Slabs
Concrete Walls
Concrete Footers
Square Columns
Round Columns
Concrete Stairs and Steps
Concrete Curbs and Gutters

Concrete calculators for specific applications

Use the concrete calculators below to help you determine concrete yardage for your specific project.

Use the calculators above for estimating purposes only.

Always double check your calculations when you figure concrete for a project. Not having enough concrete to finish can be both frustrating and problematic.

Concrete is made from aggregate (stone), sand, cement, and water.

You can make your own concrete using the raw materials and my concrete mixing ratio formula or you can buy pre-mixed concrete in bags that you just add water to.

For large projects, ordering concrete from a ready mix concrete company is usually easier and faster.

The concrete calculator APP for the Iphone and Android smartphone is terrific! I use it daily. The free desktop download is courtesy of Meet-Mr-Concrete.

Learn how I check the sub-grade to find the average thickness of a concrete floor on either the floors or slabs calculator page.

When I order concrete from a ready mix company, I always add 1/2 to 1 yard more than what it says on the calculator.
