Gravel Calculator

Calculate gravel volume and weight from area and depth using the standard formula: Cubic Yards = (Length ft × Width ft × Depth ft) ÷ 27, then multiply by material density. Crushed stone runs about 1.35 tons per cubic yard (100 lb/ft³), while pea gravel is closer to 1.3 tons per cubic yard.

Choose from #57 crushed stone, pea gravel, crusher run, river rock, decomposed granite, and sand. Each material carries its own density profile, so weight estimates stay accurate whether your supplier charges by the cubic yard or by the ton.

Built-in presets for drainage (2–3 in), walkways (2–3 in), driveways (4–6 in compacted), base courses (4–6 in), and decorative beds (2–3 in). One ton of #57 stone covers roughly 77–80 sq ft at 2–3 inches deep.

Add a customizable waste factor: 5% for a clean, flat job, 10% for spillage and uneven subgrade, and up to 15% for complex shapes or small deliveries. Most contractors build in 10% by default because gravel settles when compacted.

Get detailed cost projections per cubic yard or per ton, plus the number of dump truck loads needed. In 2026, bulk gravel runs roughly $20–$80 per cubic yard or $25–$100 per ton delivered, with #57 stone typically $30–$50 per cubic yard.
