What this calculator estimates
Estimate physical vacancy rate, occupied rate, potential rent and lost rent from vacant unit-days. It is designed for fast planning and comparison in the United States. The output is an estimate, not a binding quote, approval, tax determination, insurance offer or professional recommendation.
How to use it
Enter the requested values using a single consistent time period and currency. Select Calculate, review the headline result and supporting figures, then change one assumption at a time to compare another scenario.
How the calculation works
Vacant unit-days are divided by total available unit-days. Potential rent is scaled to the analysis period and multiplied by vacancy for the lost-rent estimate.
Important limitations
Economic vacancy can also include concessions, nonpayment, offline units and below-market rent. This calculator focuses on physical vacancy.
