### Quick Answer

**To calculate occupancy rate, divide the time that a unit was rented out by the time the unit was available for rent.** Another option is to divide the total number of units that are rented out by the total number of units.

### Full Answer

Which formula is used depends on the information required. If the occupancy rate of a single unit is required, then the ratio of the time the unit is rented to the time it was available is appropriate. To find the general occupancy rate of a set of units during a specific time period, use the number of units occupied over the total number of units available.
