Concrete Footing Volume Calculator

Estimate concrete volume for equal rectangular footings using length, width, depth, quantity and an optional allowance. Not a structural design tool.

How it is calculated

Concrete volume = length × width × depth × number of footings × (1 + allowance/100).

Worked example

Four footings measuring 0.5 × 0.5 × 0.4 m each have a combined geometric volume of 0.4 m³ before allowance.

Before you calculate

Enter dimensions determined by an appropriate design, not dimensions inferred from this calculator. Use the excavated or formed dimensions relevant to the order and select a deliberate allowance for site conditions. All footings in the calculation are assumed identical.

Interpreting the result

The result estimates material only. It does not design footing size, reinforcement, concrete strength or ground-bearing capacity. Structural and site decisions require suitable professional assessment and applicable local requirements.

Use the units shown beside each field. Monetary fields labelled EUR stay in euros; changing language does not exchange currencies. Results are estimates under the stated assumptions.
