Understanding Rental Property Investment Metrics
Investing in real estate is a powerful way to build wealth, but simply buying a property and renting it out doesn't guarantee a profit. To succeed, investors must understand the specific financial metrics that drive rental property performance. This calculator focuses on the two most critical indicators: Monthly Cash Flow and Cash on Cash Return (ROI).
What is Cash Flow?
Cash flow is the net amount of money moving into or out of your rental business each month. It is calculated by taking your total income (mostly rent) and subtracting all expenses. Expenses include your mortgage payment (principal and interest), property taxes, insurance, HOA fees, and allocations for maintenance or vacancy.
Positive Cash Flow: This means the property pays for itself and puts extra money in your pocket every month. This is the goal for most "buy and hold" investors.
Why Cash on Cash Return Matters
While cash flow tells you how much money you make monthly, Cash on Cash Return (CoC ROI) tells you how hard your money is working for you. It calculates the annual return on the actual cash you invested (Down Payment + Closing Costs).
Formula: (Annual Pre-Tax Cash Flow / Total Cash Invested) × 100
For example, if you invest $50,000 cash to buy a property and it generates $5,000 in positive cash flow per year, your Cash on Cash Return is 10%. This metric allows you to compare real estate returns against other investment vehicles like stocks or bonds.
Common Rental Expenses to Consider
- Vacancy Rate: You won't have a tenant 100% of the time. It's wise to budget 5-8% of rent for vacancy.
- CapEx (Capital Expenditures): Big ticket items like a new roof or HVAC system.
- Property Management: If you don't manage it yourself, expect to pay 8-10% of the monthly rent to a manager.
Use the calculator above to adjust your purchase price, down payment, and expense estimates to see how they impact your bottom line before making an offer.
