Calculate Vacancy Rate
Enter property, rent, downtime, and loss details. Results will appear above this form after submission.
Formula Used
Rentable Units = Total Units − Off-Market Units
Physical Vacancy Rate = Vacant Units ÷ Rentable Units × 100
Available Vacancy Rate = Available Vacant Units ÷ Rentable Units × 100
Occupancy Rate = Occupied Units ÷ Rentable Units × 100
Potential Income = Rentable Units × Monthly Unit Income × Period Factor
Economic Vacancy Rate = Total Income Loss ÷ Potential Income × 100
Annualized Loss = Total Income Loss × 365 ÷ Period Days

Vacancy Rate Guide
What Vacancy Rate Means
A vacancy rate shows how much rentable space sits empty during a selected period. It is useful for landlords, property managers, investors, hotels, storage facilities, and workforce planners. A low rate usually means strong demand. A high rate may show weak pricing, slow leasing, poor marketing, or seasonal turnover.
Physical And Economic Views
Physical vacancy focuses on units. It compares vacant units with total rentable units. This is the simplest view. It helps teams see how much space is not occupied right now. Economic vacancy focuses on money. It compares lost income with potential income. This can reveal a bigger problem. One expensive empty unit can hurt more than several low rent units.
When To Use The Calculator
Use this calculator before rent reviews, monthly reports, budget meetings, and acquisition checks. Enter all units in the property. Remove spaces that are off market because of repair, legal limits, or planned renovation. Add the number of vacant units. Then add rent, other income, turnover days, concessions, and collection losses. The tool converts these inputs into occupancy, physical vacancy, economic vacancy, and annualized lost rent.
How To Read The Results
Compare the result with your target rate and market benchmark. If your physical vacancy is above target, leasing speed may need attention. If economic vacancy is high, review rent loss, concessions, bad debt, and downtime. If occupancy is strong but income loss remains high, the issue may be rent collection or heavy discounts.
Best Reporting Practice
Good vacancy analysis should be repeated often. Use the same period length each time. Keep definitions consistent. Track results by property, unit type, building, or manager. The trend is often more useful than one result. A sudden rise can warn you early. A steady fall can confirm that pricing, advertising, and renewal work are improving. Export the results for records and share them with owners or teams.
Advanced Review Tips
For advanced reviews, separate controllable and uncontrollable vacancy. Controllable items include pricing errors, weak follow up, poor photos, late repairs, or slow approvals. Uncontrollable items may include storm damage, major construction, or sudden local layoffs. This split makes the report fairer and more useful. It also helps teams choose the next action with confidence. Record notes each month so unusual events never distort future comparisons later.
FAQs
1. What is a vacancy rate?
Vacancy rate is the percentage of rentable units that are empty during a selected period. It helps measure demand, leasing speed, and property performance.
2. What is the basic vacancy rate formula?
The basic formula is vacant units divided by rentable units, then multiplied by 100. Off-market units should be removed from rentable units.
3. What is economic vacancy?
Economic vacancy measures income loss instead of only empty units. It includes rent loss, concessions, collection loss, and turnover downtime.
4. Why remove off-market units?
Off-market units are not available for normal leasing. Removing them creates a cleaner vacancy rate and avoids overstating leasing problems.
5. What is a good vacancy rate?
A good rate depends on location, property type, season, and market conditions. Many managers compare results with internal targets and local benchmarks.
6. How often should vacancy be calculated?
Monthly reporting is common. Weekly tracking can help during lease-up, high turnover, market changes, or large renovation periods.
7. Can this calculator work for commercial spaces?
Yes. Use spaces, suites, rooms, beds, lots, or units. Keep the same definition across all periods for better comparison.
8. Why is economic vacancy higher than physical vacancy?
It may include concessions, unpaid rent, long turnover, or high-value vacant units. This means income loss is larger than unit count suggests.
