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.
