Vacancy Rate Calculator

Even a single vacant unit has a measurable impact on your annual income — this calculator makes that impact visible by converting a raw vacancy count into a rate, a monthly loss, and an annual loss figure. Enter your total units, vacant units, and rent per unit to see the numbers. Use it to model different occupancy scenarios when underwriting a new acquisition.

Frequently Asked Questions

What is a normal vacancy rate for rentals?
The national average vacancy rate for residential rentals is typically 5–7%. In tight markets like major urban cores, it can be 2–4%. In rural or high-supply markets, it may exceed 10%. Always underwrite with a vacancy assumption even if your units are currently occupied.
How does vacancy affect my cash flow?
Every vacant unit-month is lost income you can never recover. A single vacant unit at $1,500/month costs $18,000 in annual gross rent. When underwriting, most investors use a 5–10% vacancy factor applied to gross scheduled income even when fully occupied.
What's the difference between vacancy rate and occupancy rate?
They are inverses: Occupancy Rate = 100% − Vacancy Rate. A 7% vacancy rate means 93% occupancy. Both metrics describe the same phenomenon from opposite directions.
How can I reduce my vacancy rate?
Price competitively, keep the property well-maintained, respond quickly to maintenance requests (tenant retention), and start marketing units 30–60 days before a lease ends. Tenant turnover is the primary driver of vacancy.
