About Rental Property Calculator
Use this rental property calculator to estimate monthly cash flow, cap rate, cash-on-cash return, expense mix, and potential profit after sale. It is a planning model, not financial advice.
How to Use
Enter purchase, loan, rent, and optional expense assumptions.
- Enter purchase price, financing terms, and monthly rent.
- Open more options for closing costs, repairs, taxes, vacancy, management, and sale assumptions.
- Review cash flow, return metrics, and expense breakdown.
Examples
-
Rental property with 20% down
Purchase price: $250,000 Down payment: 20% Loan term: 30 years Interest rate: 6.5% Monthly rent: $2,200 Closing costs: $7,000 Repairs: $10,000 Property tax: $3,000/year Insurance: $1,200/year Vacancy: 5% Management: 8% Maintenance: $150/month Appreciation: 3% Holding period: 10 years Selling costs: 6% Monthly mortgage: $1,264.14 Total monthly expenses: $2,050.14 Monthly cash flow: $149.86 Cash-on-cash return: 2.68% Capitalization rate: 6.79% Estimated total profit: $66,804.02
-
Higher-cash-flow rental
Purchase price: $180,000 Down payment: 25% Loan term: 30 years Interest rate: 5.75% Monthly rent: $1,850 Closing costs: $5,000 Repairs: $8,000 Property tax: $2,400/year Insurance: $960/year Vacancy: 4% Management: 7% Maintenance: $120/month Other costs: $40/month Appreciation: 2.5% Holding period: 8 years Selling costs: 5% Monthly mortgage: $787.82 Total monthly expenses: $1,431.32 Monthly cash flow: $418.68 Cash-on-cash return: 8.66% Capitalization rate: 8.04% Estimated total profit: $55,539.85
Real-World Usage Scenarios
- Investment Property Benchmarking - Comparing Yields - Evaluate multiple listings by normalizing metrics like Cap Rate and Cash-on-Cash return. This allows for an objective comparison between a high-priced urban apartment and a more affordable multi-family unit in a suburban area.
- Mortgage Leverage Simulation - Loan Structure Analysis - Determine how different down payment percentages and interest rates affect your monthly cash flow. Use the tool to find the 'break-even' point where financing costs do not exceed rental income.
- Renovation Impact Analysis - ROI Evaluation - Model the financial benefit of initial repairs. By inputting estimated repair costs and the projected rent increase, investors can see if a 'fixer-upper' delivers a higher long-term profit than a turn-key property.
- Exit Strategy Forecasting - Long-Term Gains - Project the total profit at sale by factoring in annual appreciation and selling costs. This helps in deciding whether to hold the asset for 5, 10, or 20 years based on cumulative equity and market trends.
- Operating Expense Stress-Testing - Simulate 'worst-case' scenarios by increasing the vacancy rate or maintenance assumptions. This testing ensures the investment remains viable even during unexpected economic downturns or higher-than-average turnover.
Frequently Asked Questions
What is the difference between Cap Rate and Cash-on-Cash Return?
Cap Rate measures the property's intrinsic profitability excluding financing, while Cash-on-Cash Return measures the actual yield on the specific amount of cash you invested, accounting for mortgage debt.
How should I account for variable property taxes and insurance?
Enter the annual totals for property tax and insurance. If these vary significantly by year, use a conservative average or increase the 'Maintenance/Other' field to create a financial buffer.
Does this model include closing costs and acquisition fees?
Yes. Closing costs and initial repairs are factored into the total initial investment, which directly impacts the calculation of your Cash-on-Cash return and total profit at sale.
Why is the vacancy rate a critical input?
A 0% vacancy is unrealistic over long periods. Including a vacancy rate (typically 5-10%) ensures your cash flow projections account for the time spent finding new tenants or performing turnovers.
Should I include HOA fees in the calculations?
Yes. Recurring costs like HOA fees, service charges, or landscaping should be added to the 'Other Monthly Cost' field to ensure an accurate net cash flow result.
