How the footing calculator works
Estimate concrete for rectangular strip or pad footing sections. Enter one footing section's dimensions and the number of identical sections to get total concrete volume.
Total volume = length × width × depth × quantity. Waste is added after the base volume is calculated. The calculator is designed to give a useful first-pass material estimate while keeping the assumptions visible. For a purchase, compare the result with the product packaging or supplier quotation.
Common search terms for this tool include footing calculator, concrete footing calculator, footing concrete calculator, foundation footing calculator. The wording is included naturally so the page answers the same questions people ask when planning a project.
Frequently asked questions
Does this design a foundation footing?
No. It estimates concrete quantity only. Structural footing width, depth and reinforcement depend on soil, loads, climate and local codes.
Can I calculate several pad footings?
Yes. Use the quantity field for identical pad footings.
What if footings have different sizes?
Calculate each size separately and add the results together.
Why include waste?
Real excavations and formwork are rarely perfectly uniform, so the delivered quantity can differ from the theoretical volume.
