How to use it
- Enter length, width, and thickness in the fields provided.
- Input the price per cubic yard for your region.
- Click Calculate to view cubic yards, cubic feet, bag count and estimated cost.
What it does – The calculator turns the dimensions of your driveway (length, width, thickness) and the local price per cubic yard into four actionable numbers: total cubic yards of concrete, total cubic feet, the number of 80‑lb bags required, and the estimated material cost. Why it matters – Knowing the exact volume prevents over‑ordering, saves money, and helps you get accurate quotes from contractors. How to read the results – Cubic yards is the volume contractors charge for; Cubic feet shows the raw space you’ll fill; Bags tells you how many 80‑lb mix bags to buy (each 0.6 ft³); Estimated cost multiplies the yardage by your price input. All results appear instantly, so you can plan your repair budget without guesswork. You can also adjust the price per yard to compare different suppliers, and the tool automatically rounds up the bag count to ensure you have enough material.
Pro tips
- Add 5‑10% extra volume for spillage and sub‑grade variations.
- Always round up the bag count; you can’t purchase a fraction of a bag.
- Compare several local suppliers’ price per cubic yard before ordering.
- Double‑check thickness conversion; a 2‑inch slab is 0.166 ft thick.

Case study
Mike measured his 20 × 12 ft driveway at 4 in thick, entered a $115/yd³ price, and the calculator showed 0.74 yd³, 22 bags, and $85 total. He ordered 23 bags, avoided a $30 over‑order, and finished the repair on budget.
