- postDepth: 0.75
- quantity: 6
- concretePricePerM3: 125
Result: Concrete volume = 0.44 m3
A row of fence posts becomes easier to budget when each footing is calculated first. The estimate is 0.44 m3.
- holeWidth: 0.35
- holeThickness: 0.35
- holeDepth: 1.0
- postWidth: 0.12
- postThickness: 0.12
- postDepth: 0.8
- quantity: 1
- concretePricePerM3: 140
Result: Concrete cost = 15.54 $
A simple budget helps you compare bags, ready-mix, and delivery charges. The estimate is 15.54 $.
- holeWidth: 0.4
- holeThickness: 0.4
- holeDepth: 1.2
- postWidth: 0.15
- postThickness: 0.15
- postDepth: 1.0
- quantity: 4
- concretePricePerM3: 130
Result: Concrete volume = 0.68 m3
Heavier structures need deeper holes and more concrete around the buried post. The estimate is 0.68 m3.
- holeWidth: 0.3
- holeThickness: 0.3
- holeDepth: 0.95
- postWidth: 0.1
- postThickness: 0.1
- postDepth: 0.8
- quantity: 12
- concretePricePerM3: 120
Result: Concrete cost = 111.60 $
Long fence runs are easiest to plan by multiplying a single footing estimate by the total post count. The estimate is 111.60 $.
How to Interpret Your Results
| Range | Meaning | Action |
|---|---|---|
| < 0.1 m3 | Small footing | Usually suitable for light-duty posts and compact installs. |
| 0.1–0.5 m3 | Typical footing | Common for fence posts, gates, and small structural supports. |
| > 0.5 m3 | Large footing | Check excavation limits, frost depth, and delivery access before pouring. |
