Work out land use percentage split instantly with clear inputs, formula shown and shareable results.
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.
Land use share
Share = zone area / total planning area x 100
Preliminary estimate only. Land use proportions are prescribed by the applicable master plan and development control regulations.
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.
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.
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.
