How to use it
- Enter the length in feet
- Enter the width in feet
- Enter the thickness in inches
- Enter price per cubic yard and click Calculate
This tool converts your patio dimensions into the exact volume of concrete you’ll need. By entering length, width, and thickness it shows the total cubic feet and converts that to cubic yards, the standard ordering unit. It then divides the cubic feet by the 0.6 ft³ per 80‑lb bag to tell you how many bags to buy, and multiplies the cubic yards by your local price to give an estimated cost. Knowing these numbers helps you budget accurately, avoid surprise deliveries, and plan the right mix quantity before any work begins. Read the results column by column: cubic yards for ordering, cost for budgeting, bags for handling, and cubic feet for on‑site verification.
Pro tips
- Add 5‑10% extra volume for waste and spillage
- Round up bag count to the next whole bag
- Order concrete a day before the pour to ensure fresh mix
- Double‑check thickness; a common mistake is mixing inches with feet

Case study
Mike entered his 12 × 12 ft patio with a 4‑in thickness, saw a volume of 48 ft³ (1.78 yd³), learned he needed 80 bags, and got a clear $2,200 estimate, preventing a costly over‑order.
