How to Estimate Concrete Slab Cost
Concrete costs $125-$175 per cubic yard in 2026, with $150 being a solid average for budgeting. The thickness of your slab plays a big role in total cost — 4 inches is standard for patios and walkways, while driveways typically need 6 inches to handle vehicle weight.
Always order 5-10% more concrete than your calculated volume. This extra accounts for spillage, uneven ground, and waste during pouring. It's much cheaper to have a little left over than to order a second truck for a small shortfall.
For the best deal, get quotes from at least three local suppliers and consider pouring during the off-season when demand is lower. Fall and early spring often bring better rates since contractors are less busy during those times.
