Rent Increase Calculator

Calculate a proposed rent change and annual effect. Replace every default with figures that apply to your property and location.

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 — sample input: 2000 currency units
• Proposed increase — sample input: 3 %
• Months at new rent — sample input: 12 months

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.
