The gravel calculator finds the volume, mass and price of gravel used during earthworks.

If you are planning to construct a gravel driveway, this gravel calculator (gravel estimator or aggregate calculator) might prove itself useful. It will help you estimate the amount of material required to finish all earthworks. Read on to understand how to use our calculator to answer the question "how much gravel do I need?" After all, you don't want to overspend and end up with tonnes of material you will never use.

The first step is establishing the volume of gravel needed. It is equal to the volume of an excavation, and you can do it in a following way:

- Determine the length and width of a cuboidal excavation. For example, we can assume an excavation of length L = 6 m and width b = 3 m.
- Calculate the area of the excavation, multiplying the length by width. In our case,
`A = 6 * 3 = 18 m^2`

. You can also type the area of the excavation directly into the gravel estimator if you choose an excavation of some more sophisticated shape. - Determine the depth of the excavation. Let's say it's d = 2 m.
- Multiply the area and depth of the excavation to obtain its volume:
`18 * 2 = 36 m^3`

. - The volume of gravel required is equal to the volume of excavation. Our gravel calculator will display this value for you.

To calculate the weight of the material, you simply have to multiply the volume by density. You don't have to remember the density of gravel, though - by default, our calculator sets this value for you. Of course, if you decide to use some unusual aggregate, change the density as you need.

Once you determined the weight of gravel, you can use our gravel calculator to find out its cost. Simply enter the price per tonne or per cubic meter and let the gravel estimator calculate this value for you. Remember to buy some extra material to allows for small modifications of the project.

If you are going to use sand instead of gravel, try our sand calculator or the paver sand calculator.
