MEASURE ONCE. PLAN YOUR PURCHASE.

Concrete Footing Volume calculator.

Sum concrete for repeated footing segments and separately specified steps or voids.

CONCRETE

Your inputs

Use measurements from your plan and properties from your chosen product. Any prefilled values are illustrative.

Excluded or duplicated volume

yd³

Waste allowance

Shortcuts only; choose your own allowance above.

Where to get this value

Enter your own allowance. Presets are input shortcuts, not a construction recommendation.

Footing segment 1

Length

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Width

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Specified depth

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

BEHIND THE NUMBERS

How this calculation works.

Represent stepped footings as non-overlapping segments. Enter every dimension from an existing design. Deductions are applied before the waste allowance.

V = Σ(L × W × depth × count) − exclusionsCalculated with normalised units

A worked example

Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.

Excluded or duplicated volume: 0.1 m³
Waste allowance: 10 %
Length: 4 m
Width: 0.5 m
Specified depth: 0.3 m
Identical segments: 2
Length: 2 m
Width: 0.4 m
Specified depth: 0.2 m
Identical segments: 1

Concrete to order: 1.39 m³

Before you purchase

Use dimensions from your plan and properties from your chosen product. Any design spacing, section or fixing pattern must already be specified.

This tool does not choose footing dimensions or assess soil capacity.

Method: dimensional arithmetic and user-supplied specifications. Software checks: 2026-10-04. Calculation and review policy.

Check your purchase assumptions

Why adding four edge strips can overcount slab corners Reconcile volume at crossing concrete wall segments Check void deductions against their own concrete component Keep continuous strip lengths separate from station-to-station measurements
