Frequently Asked Questions

What is the Rental Property Calculator?

The FourCasa Rental Property Calculator is a free online tool that helps real estate investors analyze rental properties. It calculates cash flow, ROI (Return on Investment), cap rate, cash-on-cash return, DSCR (Debt Service Coverage Ratio), IRR (Internal Rate of Return), and generates detailed 30-year financial projections. No sign-up required.

How do I calculate rental property ROI?

To calculate rental property ROI, enter the purchase price, down payment, rental income, and expenses into the calculator. The tool automatically calculates annual ROI by dividing your total return (cash flow + equity gain + appreciation) by your total investment. It shows year-by-year projections for up to 30 years.

What is cash-on-cash return for rental property?

Cash-on-cash return measures annual pre-tax cash flow divided by total cash invested. For example, if you invest $100,000 cash and receive $8,000 annual cash flow, your cash-on-cash return is 8%. The calculator shows this automatically based on your down payment, closing costs, and net operating income after mortgage payments.

How do I calculate cap rate?

Cap rate (capitalization rate) is calculated by dividing Net Operating Income (NOI) by the property's purchase price or market value. NOI = Gross Rental Income - Operating Expenses (excluding mortgage). This tool calculates cap rate automatically and shows how it changes over time with rent increases and expense growth.

Is the property investment calculator really free?

Yes, the Rental Property Calculator is 100% free with no sign-up required. You can analyze unlimited properties, compare scenarios, and download PDF reports. There are no hidden fees or premium tiers.
