About this calculator

What is the Gravel Calculator – need for gravel and crushed stone?

The Gravel Calculator calculates the required amount of gravel or crushed stone in cubic meters and tons for filling, compaction layers, or drainage. The density of gravel varies between 2,360–3,034 lb/cu yd.

The calculator is free, works directly in the browser, and does not require registration. All figures are based on standard formulas; always check the rules that apply where you live.

Calculation Principle

Volume (m³) = Length × Width × Thickness. Weight (t) = Volume × density (kg/m³) ÷ 1000

Fill in the fields of the calculator with your information and press the calculate button – the result will be displayed immediately. Try different values to compare options.

Practical Example

Driveway base: 20 × 4 × 0.15 m = 12 m³. Density of crushed stone 1,700 kg/m³ → 20.4 tons. 10 t trucks = 3 loads.

Enter your own numbers into the calculator to get a personalized result. The calculator is designed for quick use in everyday situations.

When do you need this calculator?

The calculator is needed to support decision-making, budgeting, and cost comparisons. Getting accurate references quickly makes everyday life easier.

The result is an estimate – for important financial or construction decisions, we recommend consulting a professional.

Tips

  • Add a 10–15% compaction reserve – loose gravel compacts when driven over or walked on.
  • Ask the gravel supplier for density and grain size in advance for the calculator input.
  • Filling a yard does not require as dense crushed stone as a road base – choose the right quality.
