How to use it
- Enter the length in feet.
- Enter the width in feet.
- Enter the thickness in inches.
- Read the cubic yards, bags, and cubic feet results.
The Quikrete Calculator turns your project dimensions into the exact amount of concrete you’ll need. By entering length, width, and thickness, you instantly see three key figures: total cubic yards for ordering, the bag count required, and the volume in cubic feet for on‑site planning. Knowing the cubic yards helps you get accurate quotes from suppliers, while the bag count tells you how many standard bags to purchase, avoiding costly over‑or under‑ordering. The cubic‑feet figure is useful for checking against your mixing equipment capacity. All results are generated in real time, so you can tweak dimensions and see the impact immediately. No registration, no hidden fees—just clear, actionable numbers to keep your concrete project on budget and on schedule. You can also save the results for future reference or share them with your contractor.
Pro tips
- Add 5‑10% extra for waste and spillage.
- Round up the bag count to the nearest whole bag to ensure you have enough.
- Order a little more than the exact cubic yards to account for uneven sub‑grade.
- Double‑check thickness units; mixing inches with feet can cause large errors.

Case study
John needed a 6‑ft by 8‑ft patio 4 in thick. Using the calculator, he saw he required 0.56 cubic yards, about 10 bags. He ordered 10 bags, avoided a costly shortfall, and completed the patio on schedule.
