Boundary Wall Cost Calculator

Work out boundary wall cost instantly with clear inputs, formula shown and shareable results.

About Boundary Wall Cost Calculator

A boundary wall prices in two parts because they scale differently: the wall itself is measured by area and the foundation by length. Separating them shows why a low wall is disproportionately expensive per square metre, since the foundation cost is unchanged by height.

Formula

Cost

Total = length x height x wall rate + length x foundation rate

Worked example

With the default values below, Boundary Wall Cost Calculator returns Total boundary wall cost of $310,000.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Boundary Wall Cost figure worked out?

Total = length x height x wall rate + length x foundation rate. A boundary wall prices in two parts because they scale differently: the wall itself is measured by area and the foundation by length.

Do piers change the cost much?

Yes for tall or thin walls. Piers at 3 metre centres add material and labour but allow a thinner panel, and above about 1.8 m they are usually cheaper than thickening the whole wall.

What values do I need to enter?

This calculator takes 4 inputs: Wall length, Wall height, Wall rate, Foundation rate. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
