Understanding Vacancy Rate
How we calculate. Vacancy % = vacant ÷ total units × 100. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical Vacancy Rate case uses vacant units 12 and total units 150. Enter the same figures below to reproduce the worked path.
What is Vacancy Rate?
Leasing and underwriting KPI. Some analyses use vacant SF ÷ total SF instead of unit counts.
- Same unit definition in both inputs
- Economic vacancy may include unpaid occupied units—label if used
- Segment by building
The Formula
Worked Example
Common Use Cases
- Asset management: leasing health
- Underwriting: income haircuts
- Market reports: submarket trends
Pro Tips
- Pair with occupancy (usually complements)
- Track days vacant separately
- Watch concessions as soft vacancy
Limitations: Vacancy Rate results are educational real-estate planning aids—not appraisals, loan offers, or investment advice. Confirm figures with qualified professionals and your lender.
