Find how much gravel or crushed stone you need for a driveway or path — this crushed stone calculator gives you yards, tons, bags, and cost.
Estimate only — bag count assumes standard 0.5 cu ft (US) or 20 kg (EU) bags.
We convert your area and depth into cubic yards, then multiply by the material's typical density (about 1.2–1.4 tons per cubic yard depending on stone type) to get tons. Bag count divides total volume by a standard bag size, and cost multiplies tons by your price per ton.
Most driveways use a 4-6 inch gravel base. Enter your driveway's length and width with a 4-6 inch depth above for tons needed.
About 1.2 to 1.4 tons, depending on the stone type — crushed stone runs slightly heavier than pea gravel or decorative stone.
