Gravel Cost Calculator

Gravel Calculator — Tons, Cubic Yards & Cost

Calculate how much gravel you need — and what it will cost — for a driveway, walkway, or drainage bed. Enter your area, gravel type, and price per ton to get cubic yards, tons, and total estimated cost.

Pick the shape that best matches the area you're covering.

Most driveways use 4–6 in of gravel depth.

Density affects how many tons your order weighs.

$/ton

Check with your local supplier — gravel typically runs $15–$75 per ton.

Covers uneven sub-grade, spillage, and compaction. 10% works for most driveways.

A 20 ft × 10 ft driveway at 4 in deep needs 2.47 yd³ of gravel. With 10% waste that's 2.72 yd³ of crushed stone — about 3.53 tons — so suggested order is 2.8 yd³. At $55/ton, that's roughly $194.20.
