Are you planning to start a landscaping or home improvement project? Need more certainty about material quantities? No worries! Use the material calculator. Whether it's estimating soil, mulch, gravel, or other supplies in tons, this tool helps to determine the precise amount of materials needed for your project.

Before entering the inputs into this aggregate calculator, choose the type of material you are interested in because each type has its unique density. 

How To Calculate Material Needed?

To calculate the quantity of the material needed, follow these steps:

  • Calculate area by multiplying length with the width (Area = Length x Width)
  • Now, find the volume (Length X Width X Depth)
  • Once you get the volume, multiply it with the density of the material (Weight = Density X Volume)
  • Now convert the result into tons as 1 ton = 2,000 lb


Let's suppose you want to pour a concrete slab for your backyard project having the following dimensions:

  • Material: Concrete
  • Project: Pouring a concrete slab
  • Dimensions: Length = 5 feet, Width = 4 feet, Depth = 45 inches
  • Concrete Density: 150 lb/ft³

Now, that you have got the measurements. Now, how do you calculate material quantity and the cost of the material, if the price per unit of mass is $5/lbs and the price per unit of volume is $4/inches?


Steps to Calculate Concrete Quantity:

1. Concrete Slab Area:

$$\text{ Area (A)} = \text{Length} \times \text{Width}$$
$$\text{ Area (A)} = \ 5\ ft \times \ 4\ ft$$
$$\text{ Area (A)} = \ 20\ ft^2$$

2. Calculate Slab Volume:

$$\text{Volume (V)} = \text{Length} \times \text{Width} \times \text{Depth}$$
$$V = 5 \, \text{ft} \times 4 \, \text{ft} \times 3.75 \, \text{ft} = 75 \, \text{ft}^3$$

3. Calculate Concrete Weight:

$$\text{Weight} = \text{Volume} \times \text{Density}$$
$$\text{Weight} = 75 \, \text{ft}^3 \times 150 \, \text{lb/ft}^3 = 11,250 \, \text{lb}$$

4. Convert to Tons:

$$\text {Convert lbs to tons, since 1 ton = 2,000 lb}$$
$$\text{Weight in Tons} = \frac{11,250 \, \text{lb}}{2,000 \, \text{lb/ton}} = 5.625 \, \text{tons}$$

5. Cost of The Material:

$$\ Cost\ Per\ Pound =\ $4$$
$$\ 11,250 \, \text{lb} \times $5/\text{lb} = $56,200$$
$$\ Cost\ Per\ Cubic\ Foot\ Volume =\ $5$$
$$\ 75 \, \text{ft}^3 \times $5/\text{ft}^3 = $300$$

How Do You Calculate Material In Civil Work?

The ratio of concrete ingredients that is most commonly used in the construction of buildings and other related projects is 1:1.5:3 and 1:2:4.

The required amount of cement is, = (154÷5.5) x 1 = 28 cubic feet
The Sand you need is = (154÷5.5) x 1.5 = 42 cubic feet
The required Stone chips are = (154÷5.5) x 3 = 84 cubic feet
