Calculate concrete volume for rectangular strip or pad footings, multiple footings, waste allowance and ready-mix cost.
Concrete footing quantity
Enter footing length, width, depth and quantity. The calculator totals concrete volume and can apply the same sourced ready-mix pricing system used by Calcavera concrete tools.
Planning only
The calculator does not determine safe footing dimensions or reinforcement. Use dimensions from the structural design and local requirements.
Frequently asked questions
How much concrete do I need for a footing?
Multiply footing length, width and depth, then multiply by the number of identical footings and add the selected allowance.
Does this calculator design footing dimensions?
No. Footing size and reinforcement must come from the structural design and applicable requirements.
Can I calculate multiple footings?
Yes. Enter the number of identical footings.
Does it show ready-mix cost?
Yes when an active sourced ready-mix market rate exists for the selected market.
What does Concrete Footing Calculator & Cost Estimator calculate?
The calculator uses the measurements and values you enter and applies a defined deterministic formula. Change the inputs and the result is calculated again from those values.
Can I save this calculation to a project?
Yes. After calculating, use “Add to my project estimate” to save the result in your current Calcavera project estimate. You can repeat this with other calculators to build a multi-item project.
Can I print or save the estimate as a PDF?
Yes. Open the saved project estimate, then use the “Print / Save PDF” button. Your browser can print the estimate or save it as a PDF file.
Can I use metric and imperial units?
Yes. Where supported by the calculator, you can mix common metric and imperial input units. Calcavera converts measurements before running the calculation and shows the selected output unit.
Are the cost figures a contractor quote?
No. Cost ranges are planning estimates and appear only when an active market rate is available. Supplier pricing, labor, taxes, delivery, specifications and site conditions can change the final cost.
