Real Estate ROI Calculator - Rental Property Return

A "good" ROI depends on your market and risk tolerance. In 2026, most experienced investors target a cash-on-cash return of 8% to 12% and a total annual ROI (including appreciation and principal paydown) of 15% or higher. In high-demand coastal cities, cash flow might be lower (2-4%) with the expectation of higher long-term appreciation.

To calculate the Cap Rate, divide the Net Operating Income (NOI) by the property's purchase price. NOI is your gross annual rent minus all operating expenses (taxes, insurance, maintenance), but *before* you subtract mortgage payments. Cap rate allows you to compare the profitability of different properties regardless of how they are financed.

The 50% rule is a quick estimation tool that assumes 50% of a property's gross income will go toward operating expenses, not including the mortgage. For example, if a house rents for $2,000 per month, you should expect $1,000 to be spent on taxes, insurance, and repairs, leaving $1,000 for debt service and profit.

Yes. To find your true "Cash-on-Cash" return, you must include every dollar you spent to acquire the property, including the down payment, loan origination fees, title insurance, and initial renovations. Excluding these "sunk costs" will artificially inflate your perceived rate of return.

Vacancy is a silent killer of ROI. Even a "low" 5% vacancy rate means your property is empty for 18 days every year. In your calculations, you should always subtract a vacancy allowance from your gross rent to ensure you have enough cash reserves to cover the mortgage during tenant turnover periods.

Historically, both have returned about 10% annually. However, real estate offers unique advantages such as tax-deductible depreciation and the ability to use leverage. Conversely, stocks are more liquid and require zero management effort. Investors should model both using a professional ROI tool to see which fits their 2026 goals.

On a $300,000 mortgage, a 1% rate increase (e.g., from 6.5% to 7.5%) adds approximately $200 to your monthly payment. This $2,400 annual increase comes directly out of your net profit, potentially turning a cash-flowing property into one that requires a monthly out-of-pocket contribution.

This calculator does not model: (1) personal income taxes or capital gains taxes upon sale; (2) the benefits of depreciation (the "phantom loss"); (3) 1031 exchange deferrals; or (4) specific local business license fees. It provides a pre-tax operational and equity growth projection.

Standard guidelines suggest reserving 1% of the property value per year for maintenance, or roughly 10-15% of the monthly rent. Older properties or those in harsh climates (snow/salt air) may require 2% or more to cover major items like roofs and HVAC systems over time.

Yes. You can use this tool for any income-producing real estate. For a duplex or fourplex, simply enter the combined monthly rent of all units into the "Monthly Rent" field and use the aggregate operating expenses for the entire building.
