How to Calculate Vacancy Rate for Apartments

In real estate investing, the vacancy rate is one of the most critical metrics for measuring the performance of a rental property. It represents the percentage of all available units in a rental property that are unoccupied at a given time.

The Vacancy Rate Formula

The standard formula for calculating the physical vacancy rate is straightforward:

Vacancy Rate = (Number of Vacant Units ÷ Total Number of Units) × 100

Practical Example

Imagine you own an apartment complex with 40 units. During your monthly audit, you find that 2 units are currently empty and ready for rent.

  • Total Units: 40
  • Vacant Units: 2
  • Calculation: (2 / 40) = 0.05
  • Result: 0.05 × 100 = 5%

In this scenario, your vacancy rate is 5%, which is typically considered a healthy "market-standard" rate for residential real estate.

Physical vs. Economic Vacancy

While the calculator above focuses on Physical Vacancy (empty units), experienced investors also look at Economic Vacancy. Economic vacancy accounts for lost income even when units are physically occupied. This includes:

  • Non-payment: Tenants living in the unit but not paying rent.
  • Concessions: Offering "one month free" reduces the actual revenue.
  • Model Units: Units used for marketing that do not generate rent.

Why Vacancy Rates Matter

Understanding your vacancy rate is essential for several reasons:

  1. Valuation: Lenders and buyers use vacancy rates to determine the Net Operating Income (NOI) and the overall value of the property.
  2. Strategy: If your rate is 0%, your rents might be too low. If it's over 10%, your units might be overpriced or require maintenance.
  3. Cash Flow Management: High vacancy rates can lead to negative cash flow, as the landlord must still pay the mortgage, taxes, and insurance for empty units.

Tips to Reduce Vacancy Rates

If your calculation shows a rate higher than 7-8%, consider these strategies:

  • Improve Curb Appeal: First impressions matter for prospective tenants.
  • Incentivize Renewals: Offer small upgrades or slight rent freezes for long-term tenants.
  • Audit Marketing: Ensure your listings have high-quality photos and are posted on multiple platforms.
  • Speed Up Turnovers: Reduce the time it takes to clean, paint, and repair a unit after a tenant moves out.
