Vacancy Rate Calculation

Vacancy rate measures the proportion of rental units that are unoccupied at a given time.

Formula

Vacancy Rate = Vacant Units / Total Units x 100

Occupancy Rate = 1 - Vacancy Rate

Impact

  • Each vacant unit represents lost income
  • Vacancy directly reduces effective gross income and NOI
  • Target vacancy varies by market: 3-5% is tight, 8-10% is average, above 15% is concerning

    • Exemple Résolu

    A 10-unit building has 1 vacant unit with average rent of $1,500/month.

    1. Vacancy rate: 1 / 10 x 100 = 10.0%
    2. Occupancy rate: 90.0%
    3. Monthly vacancy loss: 1 x $1,500 = $1,500
    4. Annual vacancy loss: $1,500 x 12 = $18,000
