What this calculator estimates
Calculate a proposed rent change and annual effect. It combines the inputs below to produce New monthly rent. 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 $2,060. This is an illustration, not a market quote. Change one input at a time to understand what drives the result.
Inputs and assumptions
- Current monthly rent per unit — sample input: 2000 currency units
- Proposed increase — sample input: 3 %
- Number of units at this rent — sample input: 1 units
- Months at new rent in the first year — sample input: 12 months
- Projection period — sample input: 5 years
- Vacancy allowance — sample input: 0 %
- Annual operating-cost increase — optional — sample input: 0 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.
Calculation details
