1
Enter Monthly Rent
The full monthly rent at 100% occupancy. Vacancy loss is calculated as rent x vacancy percentage x 12.
2
Set Current Vacancy
National average is 6-7%. Class A properties: 3-5%. Class C: 8-15%. Seasonal markets vary widely. Use your actual experience or local market data.
3
Enter All Expenses
Expenses continue whether the unit is occupied or vacant: mortgage, taxes, insurance, and sometimes maintenance. Only management fees decrease with vacancy.
4
Read Break-Even Occupancy
The minimum occupancy rate at which cash flow is zero. Below this, you're losing money every month the unit sits vacant.
5
Check the Vacancy Table
The table shows cash flow at 0%, 5%, 8%, and 12% vacancy. This shows your risk exposure if tenant turnover increases.
6
Value the Vacancy Reduction
Reducing vacancy from 8% to 4% on $1,500/mo rent saves $720/yr. At a 5.5% cap rate, that's $13,090 in additional property value.

Vacancy is one of the biggest variables in rental property performance. A 4% difference in vacancy rate (8% vs 4%) on a $1,500/mo property means $720/year in lost income -- and at a 5.5% cap rate, it's $13,090 in property value.


Vacancy occurs in two forms: physical vacancy (unit is empty) and economic vacancy (unit is occupied but at below-market rent). Both reduce income. The calculator models physical vacancy.


Strategies to reduce vacancy: competitive pricing (not too high, not too low), excellent maintenance response times, tenant retention programs, and thorough upfront screening to select long-term tenants.
