About Parking Turnover Calculator

Turnover is vehicles parked per space per day, and occupancy is the share of available space hours actually used. The two together characterise a car park: high turnover with moderate occupancy means efficient short stay use, while low turnover with high occupancy means the spaces are held all day by a few users.

Formulas

Turnover

Turnover = vehicles parked per day / spaces

Occupancy

Occupancy = vehicles x average duration / (spaces x operating hours)

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 3 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.
