How to calculate sonotube concrete
This calculator finds concrete volume needed for cylindrical sonotube piers, from tube diameter, depth, and pier count.
How the calculation works
Volume (cubic yards) = π × (Diameter ÷ 24)² × Depth × Count ÷ 27, converting diameter from inches to feet and the final cubic-foot result to cubic yards.
Example
12-inch diameter tubes, 4 ft deep, 6 piers: π×(12÷24)²×4×6÷27 = π×0.25×4×6÷27 ≈ 18.85÷27 ≈ 0.70 cubic yards.
Frequently asked questions
How is Result calculated?
Result = pi() × pow([Tube diameter] ÷ 24, 2) × [Depth] × [Number of piers] ÷ 27.
Is the Sonotube Concrete free to use?
Yes — every calculator on Simple Calculator Tools is free, runs in your browser, and does not require an account.

Pro Tips for Sonotube Concrete
- Confirm actual required pier depth from your local frost line depth and structural requirements before finalizing the calculation.
- Order a bit extra concrete beyond the exact calculated volume to account for minor tube irregularities and any spillage during the pour.
Common Sonotube Concrete Mistakes to Avoid
- Using a generic pier depth instead of your specific local frost line requirement, which varies significantly by climate and is critical for proper footing performance.
