What the estimate includes
Vacancy cost is more than missed rent. Cleaning, make-ready repairs, utilities, marketing and other turnover costs can change the real financial impact.
RentFlow Pro extends this concept into connected Vacancy Cost, Property Profitability, Cash-Flow Forecasting and portfolio financial intelligence.

Vacancy cost calculator FAQ
What does the vacancy cost calculator include?
It estimates lost rent using a simple 30-day month and adds the turnover costs you enter, including cleaning, repairs, utilities, marketing and other costs.
Does vacancy cost mean only lost rent?
No. Lost rent is one component. Direct turnover costs can materially increase the financial effect of a vacancy.
Is the result accounting or tax advice?
No. The calculator is a planning estimate for rental operations and does not replace accounting, tax, legal or other professional advice.
Do I need a RentFlow account to use it?
No. The calculator is free and public. RentFlow Pro includes deeper Vacancy Cost and portfolio financial intelligence inside the landlord workspace.
