Aggregate Calculator

Aggregate Calculator – Estimate Gravel, Sand & Crushed Stone

When it comes to construction, landscaping, or home improvement projects, knowing how much aggregate material you need is essential. An Aggregate Calculator helps you determine the quantity of sand, gravel, crushed stone, or concrete required based on the dimensions of your project.

Whether you’re building a driveway, laying a patio, or pouring concrete, this tool takes out the guesswork — saving you time, money, and waste.

Planning a construction project—whether it’s a driveway, patio, or foundation—requires knowing exactly how much material you need. Our free Aggregate Calculator simplifies the process, helping you estimate quantities of gravel, sand, concrete, or other aggregates in just a few clicks. With instant results and a visual chart breaking down your material needs, you can budget effectively and avoid costly mistakes.

What Is Aggregate?

Aggregate refers to coarse- to medium-grained materials used in construction. It includes:

• Gravel

• Crushed stone

• Sand

• Recycled concrete

Aggregates are essential for creating strong foundations, mixing concrete, improving drainage, and reinforcing durability in roads and buildings.

What Is an Aggregate Calculator?

An Aggregate Calculator estimates the volume or weight of materials like gravel, sand, crushed stone, or concrete required for construction or landscaping projects. By inputting dimensions (e.g., length, width, depth) and material type, it calculates how much you need, often converting between cubic yards, tons, or bags for convenience.

Key uses of aggregates:

• • Gravel: For driveways, pathways, or drainage.

• • Sand: For concrete mixes, masonry, or leveling.

• • Concrete: For slabs, footings, or patios.

• • Crushed Stone: For road bases or landscaping.

Manually calculating material needs can lead to errors or over-ordering. Our Aggregate Calculator automates the math, saving time and money.

How Does the Aggregate Calculator Work?

The calculator estimates the volume and weight of the aggregate material you need based on three main inputs:

1. Length – in meters or feet

2. Width – in meters or feet

3. Depth – in inches, cm, or feet

Once entered, the calculator computes the volume in cubic meters (m³) or cubic feet (ft³) and provides an estimate in tons, kilograms, or pounds based on the selected material density.

Formula for Aggregate Calculation

Here’s the simple formula:

If using metric units:

If using imperial units:

Then multiply by the material density to get the total weight.

Common Material Densities

Note: Density may vary depending on moisture and compaction.

Example Calculation

Let’s say you’re building a gravel driveway:

• Length = 10 meters

• Width = 4 meters

• Depth = 0.2 meters (20 cm)

Volume = 10 × 4 × 0.2 = 8 m³

Assuming gravel density = 1,800 kg/m³

Total weight = 8 × 1,800 = 14,400 kg or 14.4 tons

You’ll need approximately 14.4 metric tons of gravel.
