How to use it
- Enter length, width, and thickness of the pad.
- Input the current price per cubic yard of concrete.
- Click “Calculate” to see volume, bags, and cost.
- Use the results to order the right amount of material.
The Concrete Pad Cost Calculator quickly tells you how many cubic yards of concrete you’ll need, how many 80‑lb bags that translates to, and the estimated price based on your local rate. Knowing the exact volume prevents over‑ordering, which saves money and reduces waste. The results are shown in four units: cubic yards for ordering bulk, cubic feet for quick checks, bag count (each bag = 0.6 ft³), and the total cost. For example, a 10 ft × 10 ft pad 4 in thick yields 1.23 yd³, about 56 bags, and a cost of $148 at $120/yd³. Read each line to confirm you’re ordering the right amount before you call the supplier.
Pro tips
- Add 5‑10% waste to volume before ordering.
- Round up bag count; you can’t buy a fraction of a bag.
- Compare delivery fees; larger orders may qualify for free haul.
- Double‑check thickness conversion; inches must be divided by 12.

Case study
Mike needed a 10 × 10 ft, 4‑in concrete slab for his workshop. Using the calculator, he saw he required 1.23 yd³, 56 bags, and $148 total. He ordered exactly that amount, avoided a $200 over‑order, and completed the slab on schedule.
