About Land Use Percentage Split Calculator

A land use budget expresses each zone as a percentage of the planning area so the plan can be compared against norms: roughly 40 to 55 percent residential, 3 to 5 percent commercial, and 20 to 25 percent for roads, utilities and open space. The unallocated remainder is where reserves for future use and unbuildable land sit.

Formula

Land use share

Share = zone area / total planning area x 100

Worked example

With the default values below, Land Use Percentage Split Calculator returns Residential share of 55.00%. 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.
Preliminary estimate only. Land use proportions are prescribed by the applicable master plan and development control regulations.

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 Land Use Percentage Split figure worked out?

Share = zone area / total planning area x 100. A land use budget expresses each zone as a percentage of the planning area so the plan can be compared against norms: roughly 40 to 55 percent residential, 3 to 5 percent commercial, and 20 to 25 percent for roads, utilities and open space.

Why is the infrastructure share so large?

Roads alone typically take twelve to eighteen percent of a residential layout, and mandated open space adds ten. The land is not saleable but the cost of servicing it falls on the plots that are.

What values do I need to enter?

This calculator takes 4 inputs: Total planning area, Residential area, Commercial and mixed use area, Roads, utilities and open space. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
