What this calculator estimates
Estimate lost rent and carrying costs during vacancy. It combines the inputs below to produce Total vacancy cost. Every assumption remains editable so the estimate can reflect the property, financing and location being evaluated.
Worked example
Using the displayed sample assumptions, the calculator produces $6,000. This is an illustration, not a market quote. Change one input at a time to understand what drives the result.
Inputs and assumptions
- Monthly market rent — sample input: 2500 currency units
- Vacant days — sample input: 30 days
- Monthly carrying costs — sample input: 1500 currency units
- Turnover work — optional — sample input: 2000 currency units
How to interpret the result
Review cash flow together with reserves, vacancy and financing risk. Compare a conservative case with an expected case and keep a record of the assumptions used.
Common mistake to avoid
Do not treat gross rent as net operating income. Local definitions, taxes, lending practices and measurement requirements can materially change the result.
