How to estimate concrete driveway cost
Calculate base volume in cubic yards: length × width × thickness in feet ÷ 27. Apply 5–10% waste for grade variation, spillage, and uneven subbase, then multiply the suggested ready-mix order by your supplier's price per cubic yard.
The concrete material line is only part of a driveway budget. Site demolition, excavation, compacted gravel base, reinforcement, forms, control joints, finishing, sealing, permits, delivery, pump access, and labor can exceed the concrete cost itself.
What changes the cost of a concrete driveway?
| Cost factor | Why it matters |
|---|---|
| Thickness | Moving from 4 to 5 inches increases concrete volume by 25%. |
| Base condition | Soft or poorly drained soil may require more excavation and gravel. |
| Reinforcement | Rebar or welded wire mesh adds material and labor. |
| Finish | Broom finish is typically simpler than exposed aggregate, color, or stamping. |
| Truck access | Restricted access may require wheelbarrows or a concrete pump. |
