Concrete Driveway Calculator

Pouring a new concrete driveway is one of the most expensive and permanent home improvements you can make. Because driveways cover a massive surface area, ordering the wrong amount of concrete can be a very costly mistake.

By using our concrete driveway calculator, you can instantly determine exactly how many cubic yards of concrete you need to order from the ready-mix plant. Our tool also acts as a concrete driveway cost calculator, allowing you to estimate your total raw material costs before requesting bids from contractors.

To manually calculate concrete for a driveway, you need to find the three-dimensional volume of the slab.

A driveway is essentially just a very large slab. Therefore, the mathematics behind a cement driveway calculator are exactly the same as a standard slab estimator. Always remember to add a 10% waste margin, as driveway subgrades are notoriously uneven, causing the concrete to puddle slightly thicker in certain areas.

The most critical decision you will make when using a driveway calculator for yardage is deciding on the thickness.

A 4-inch thick driveway is the residential standard. It is perfectly capable of supporting standard passenger cars and light SUVs, provided the gravel sub-base underneath is properly compacted.

However, if you plan to park heavy pickup trucks, large RVs, or boats on the driveway, you should absolutely upgrade to a 6-inch thick slab. While increasing from 4 inches to 6 inches will increase your concrete costs by 50%, it massively increases the load-bearing capacity of the slab, preventing cracking and sinking down the road.
