About this calculator

Driveway area drives material quantities. Concrete driveways: 4-6 inches thick. Asphalt: 2-3 inch top over compacted base. Gravel: 4-6 inch lift over compacted sub-grade. Standard 1-car driveway: 10-12 ft wide; 2-car: 18-24 ft.

Frequently asked

Concrete or asphalt?+
Concrete: lasts 30-40 years, more expensive ($5-10/ft²). Asphalt: lasts 15-20 years, cheaper ($3-7/ft²).
Gravel maintenance?+
Cheapest install but needs grading and top-up every 1-3 years. Best for rural / long driveways.
Slope requirements?+
1-2% for drainage. Avoid 5%+ if at all possible (slick when icy).
Sealing?+
Asphalt needs seal coat every 2-5 years. Concrete: optional sealing for stain resistance.
Permits?+
Often required if widening or replacing a driveway connecting to a public road. Check city/county.
