Concrete Calculator Guide
Slabs (Including Irregular Shapes)
Rule of Thumb: Add 1/4″ to your slab thickness to account for slight variations in grade.
Check Your Grade: If your depth varies (e.g., from 2.5″ to 4″), the best fix—for both quality and cost—is to re-grade evenly.
Odd Shapes Made Easy: Break complex shapes into simple rectangles or triangles. For example, a driveway 13′ wide at one end and 17′ at the other, 25′ long, can be estimated as 15′ × 25′. (The average width is 15’.)
Steps
Break each step into a box (height × width × depth).
Calculate the volume for each step, then add the totals together.
Notes
Always Add a Safety Margin
Never order the exact amount. Add at least 0.25 cubic yards to your final total.
Running short can be costly in both time and quality. A little extra concrete is far better than not enough.
