Gravel Calculator: Estimate Gravel Needed, Wastage, and Cost

Estimate the amount of gravel needed for your project with our easy-to-use gravel calculator. Get accurate results including wastage and cost estimates.

Result

Gravel required: 10.00 cubic meters

Total with wastage: 11.00 cubic meters

Total cost: 825.00 €

This tool allows you to estimate the amount of gravel needed for your project using metric units (meters and centimeters). It also helps you calculate the approximate cost based on the price per ton.

How to Use the Gravel Calculator

To get an accurate estimate, please enter the dimensions of your area in meters and the depth in centimeters.

1. Measure the Area

Use a measuring tape to determine the length and width of the space where you plan to lay gravel.

2. Set the Depth

Choose the depth in centimeters according to the intended use:

Walkway: 5 cm
Driveway: 10 cm
Patio foundation: 15 cm

3. Determine the Density

The density of gravel varies depending on the type. Generally, it is about 1.5 tons per cubic meter.

4. Enter the Cost per Ton

The price of gravel depends on the region and type. Enter an average cost to estimate your budget.

Gravel Quantity Calculation

The gravel quantity is calculated as follows:

Volume = Length (m) × Width (m) × Depth (m)
Total weight = Volume (m³) × Density (tons/m³)

A 10% surplus is recommended to account for losses.

Example Calculation

Suppose you have an area that is 5 m long and 3 m wide with a depth of 10 cm (0.1 m):

Volume = 5 × 3 × 0.1 = 1.5 m³
Total weight = 1.5 × 1.5 = 2.25 tons
Weight with losses = 2.25 × 1.1 = 2.48 tons

If the price of gravel is €30 per ton:

Total cost = 2.48 × 30 = €74.4

Tips for Buying and Installing

Prepare the ground: Level and compact the surface before laying the gravel.
Choose the right type: Crushed gravel for stability, rounded gravel for aesthetics.
Use a geotextile fabric: It prevents weed growth.
