Concrete Driveway Cost Calculator

The Concrete Driveway Cost Calculator estimates concrete volume, gravel base, rebar grid, formwork length, and total material cost for a new concrete driveway. Enter driveway dimensions, rebar layout, and local material prices to build a realistic budget before you pour.

Material quantities

Concrete volume equals length times width times slab depth. Gravel base volume uses the same footprint with a separate gravel depth. Rebar length is estimated from a rectangular grid spaced evenly inside the slab edges. Form length is the perimeter: $2 \times \text{length} + 2 \times \text{width}$.

Cost estimation

Multiply each material quantity by your supplier price per unit. Concrete is priced per cubic meter or yard, gravel per cubic volume, rebar per linear foot or meter, and forms per linear length. The total is a material estimate only and does not include labor, excavation, or finishing.

Frequently Asked Questions

How thick should a residential concrete driveway be?

Most passenger-car driveways use 4 to 6 inches (10 to 15 cm) of concrete over a compacted gravel base. Heavier vehicles may need 6 to 8 inches.

Do I need rebar in a concrete driveway?

Many driveways use a rebar or wire mesh grid to control cracking. A common layout spaces bars 12 inches apart with 3 inches inset from each edge.

How deep should the gravel base be under concrete?

A 4 to 8 inch compacted gravel layer is typical. It improves drainage and provides a stable sub-base before the concrete pour.

Does this include labor and finishing costs?

No. This calculator estimates material quantities and material cost only. Add labor, equipment, sealing, and permits separately for a full project budget.
