As of 2015, the average cost of driveway gravel varies between $10 to $60 for a cubic yard. The size and type of gravel determines the prices as well as if the customer picks it up personally or has it delivered to the site of the driveway.
A single-car driveway that is 12 feet by 25 feet requires about 10 to 14 tons of gravel, which can cost about $100 to $800 if it is poured nine inches thick. With installation and labor costs, this project costs about $300 to $1,000, or $0.75 to $3.00 per square foot. Some factors that increase the price of a driveway include curves, slopes and poor soil conditions.
