Concrete Footing Quantity Calculator
Estimate specified strip footings and rectangular or cylindrical pads, then separate net concrete, allowance-adjusted order quantity, supplier-rounded purchase quantity, and optional local cost.
Part of the Concrete & Masonry calculators — see all tools in this category.
Concrete footing quantity
Add only specified strip and pad geometry, then keep net concrete, ordered concrete, supplier rounding, and optional price separate.
Preparing calculator controls…
| Net concrete | 1.16 m³ |
|---|---|
| Ordered after allowance | 1.16 m³ |
| Supplier-purchased quantity | 1.25 m³ (5 increments) |
Current result
Order 1.25 m³ (5 whole supplier increments).
- Measured net concrete
- 1.16 m³
- After-allowance order need
- 1.16 m³
- Actual supplier-purchased stock
- 1.25 m³
- Explicit shared overlaps
- 0 m³
Net is the entered section volume minus only the shared overlaps you enter. The allowance affects only the after-allowance order need, once. Supplier-purchased stock then rounds that aggregate order up to whole increments, so it may exceed the order need. A blank optional rate remains unpriced, not a zero-cost quote.
- Enter only dimensions and shared junction volumes specified for this project; this calculator does not select footing size or depth.
- Supplier units are rounded after the aggregate order allowance. Net, ordered and supplier-purchased volumes are separate quantities.
| Material | Net need | Order quantity |
|---|---|---|
| User-specified concrete supply | 1.16 m³ (net) | 1.16 m³ (net) (5 packs) |

How it works and assumptions
Add each specified strip, rectangular pad, or cylindrical pad section. If two entered sections share a known volume, enter that overlap once. Add an allowance only if it is part of your purchase plan, then enter the supplier’s actual order increment.
The calculator does not choose a footing or make compliance claims. Continue with the live Specified Footing & Formwork Quantity Takeoff guide, then use the Itemized Slab & Shed Base Estimate guide to manually carry compatible quantities into a quote scope; neither guide transfers results or creates an exporter.
Worked example
The calculator includes a separate synthetic worked example and starts with the C11 UAT geometry, so you can check the net 1.16 m³ result and then change the allowance to test the order stage.
