Cost of a concrete driveway. Gary Salerno, owner of A+ Plus Concrete & Foundation Repair in Carnegie, Pennsylvania, says the average cost of a concrete driveway is $5,000 to $20,000, depending on several variables. He adds contractors who use the best materials typically charge $7 to $10 per square foot.

On average, the cost per square foot for asphalt will run between $2.50 to $4.00.Fluctuations in crude oil prices can cause fluctuations in asphalt prices but the price will remain around this range.Concrete, on the other hand, can run between $4.00 to $6.00 per square foot for basic installation and can cost more depending on different finishes and detail.Itâs not unheard of to have a stained concrete driveway with a smooth finish cost over $15.00 per square foot.oncrete, on the other hand, can run between $4.00 to $6.00 per square foot for basic installation and can cost more depending on different finishes and detail.
