Measure vacant units, income leakage, and occupancy accurately. Compare physical vacancy and economic vacancy instantly. Plan leasing actions using clear metrics and visual trends.
Use the sample defaults or replace them with actual property figures. The calculator uses physical vacancy, economic vacancy, concessions, and credit loss together.
This tool supports leasing reviews, owner reporting, and internal budgeting. It estimates vacancy-related income leakage. It does not replace accounting records or lease audits.
This sample shows a twelve-month review for a mid-sized rental property.
| Metric | Example Value | Notes |
|---|---|---|
| Total Units | 20 | Total rentable apartments in the property. |
| Occupied Units | 17 | Three units remained vacant during the review. |
| Average Monthly Rent Per Unit | $1,200.00 | Scheduled market rent before loss adjustments. |
| Other Monthly Income Per Unit | $40.00 | Parking, pet rent, storage, or utility income. |
| Concessions Total | $1,800.00 | Move-in specials or discounts granted to residents. |
| Bad Debt Total | $1,200.00 | Uncollected rent written off during the period. |
| Lost Fees or Recoveries | $600.00 | Application, utility, or chargeback income missed. |
| Total Rentable Area | 18,000 sq ft | Used to estimate loss per square foot. |
Enter the property name if you want a labeled report. Choose the number of months you want to review, such as one month, one quarter, or a full year.
Enter total units and occupied units. The calculator derives vacant units automatically and uses them to estimate physical vacancy loss and lost ancillary income.
Enter the average monthly rent per unit and the monthly non-rent income per unit. Add concessions, bad debt, and other missed fees for the same period.
Optionally add total rentable area and your target occupancy rate. Submit the form to view vacancy loss, effective gross income, monthly averages, target gaps, and a waterfall chart.

Vacancy loss is the income a property misses because units are unoccupied or related income was not collected. It often includes lost rent, missed fee income, concessions, and credit loss during the review period.
Physical vacancy measures empty units. Economic vacancy measures all income leakage. A property can have strong occupancy but still show weak economic results when concessions, bad debt, or missed fees are high.
Vacant units often reduce more than rent. Parking, storage, pet charges, utility reimbursements, and other recurring fees may also disappear when a unit is not occupied. Including them gives a fuller income picture.
Yes, many operators include concessions when reviewing economic vacancy. They reduce collectible income, even when the unit is occupied. Tracking them helps compare leasing strategy against occupancy gains.
Bad debt comes from rent or charges billed but not collected. Vacancy comes from units or income streams that were never occupied or earned. Both lower effective gross income and should be tracked together.
Monthly analysis helps with leasing control and recent performance. Annual analysis gives a broader ownership view and smooths short-term fluctuations. Many managers review both for better operational decisions.
It estimates how much income remains below your chosen occupancy goal. This helps managers see the dollar value of missed leasing performance and prioritize turns, marketing, pricing, and renewal strategies.
Yes, with adapted inputs. You can treat suites as units and use average monthly rent equivalents. Add rent abatements, credit loss, and missed recoveries to estimate a similar vacancy impact view.
