Estimate Amount Of Concrete Needed

Learn the required concrete density or estimate it based on the chosen concrete mix.

Estimate amount of concrete needed.

Estimate the volume of concrete needed using geometrical formulas and the construction plans. Calculate the volume of concrete you need in cubic yards. Calculate the volume of the area after determining the shape of the area see the chart below by multiplying in the thickness of the concrete. To determine how many bags of concrete you will need divide the total cubic yards needed by the yield.

Multiply the volume by the density in the same units optional estimate the amount of readymix concrete you would need. The formula for cubic yards is this. Length x width x thickness. Concrete cost estimator helps homeowners and contractors calculate the amount of pre mixed concrete needed for footings slabs and walls round columns as well as concrete stairs.

For concrete the formula for volume is as follows. Enter the dimensions of your project and you will get results in cubic yards as well as the number of concrete mix bags needed for the job. Essentially you are solving for volume and then converting to cubic yards. This free concrete calculator estimates the amount of concrete necessary for a project and can account for different shapes and amounts of concrete.

You get 1 3 cu. 33 x 037 1 22 cubic yards. The best way to calculate how much concrete you re going to need in cubic yards is to do the following. Multiply the length 10 ft by the width 10 ft by the depth 35 ft or 4 in and divide it by 27 the number of cubic feet in a cubic yard.
