Rental Property Mortgage Calculator
Investing in rental property? Knowing your monthly mortgage payment is crucial to estimating profits and returns. The Rental Property Mortgage Calculator helps landlords and investors see exactly what they’ll owe each month — including principal, interest, taxes, insurance, and HOA (if any).
Whether you’re buying your first rental or expanding a portfolio, this calculator gives a full financial snapshot — monthly payments, interest over time, and how loan choices affect long-term cash flow.
⚙️ What the Calculator Does
The Rental Property Mortgage Calculator shows:
- Monthly mortgage payment (principal + interest)
- Total loan cost over the life of the loan
- Amortization schedule (interest vs. principal each month)
- Total interest paid
- Optional: property tax, insurance, HOA fees
- Impact of down payment and loan term on monthly cost
- Optional: integrates with ROI or cash flow estimates for rental properties
🧭 How to Use the Rental Property Mortgage Calculator
- Enter Property Purchase Price
Input the price of the property you’re buying. - Input Down Payment Amount or Percentage
Choose how much cash you’ll put down. A higher down payment = smaller loan and lower monthly payments. - Enter Loan Term
Typically 15, 20, or 30 years. Shorter terms mean higher monthly payments but less total interest. - Add Interest Rate
Input the annual interest rate offered by your lender. - Include Extra Costs (Optional)
Add estimated property taxes, insurance, HOA fees, and PMI (if required). - Calculate Monthly Mortgage
The calculator displays your monthly payment, total loan cost, and amortization summary. - Analyze Scenarios
Adjust down payment, loan term, or interest rate to see how each affects your payment and cash flow.
🧾 Example Calculation

- Purchase Price: $300,000

- Loan Amount: $240,000
- Interest Rate: 4.5%
- Loan Term: 30 years

- Insurance: $60/month
- HOA: $0
Results:

💡 Tip: If you rent the property for $2,000/month, your mortgage consumes about 71% of your income before other expenses — a healthy starting ratio for a positive cash flow property.

2. What is included in my monthly payment?
Principal, interest, and (optionally) taxes, insurance, and HOA.
3. Does it include PMI?
Yes, if your down payment is below 20%.
4. Can I compare multiple loan terms?
Yes — try 15 vs. 30 years to see how payments and total interest change.
5. Does interest rate significantly affect payment?
Yes — even a 0.5% rate change can alter monthly cost by hundreds.
6. Can I add rental income to see profit?
Yes — advanced calculators let you subtract expenses and mortgage from rent to see net cash flow.
7. What’s a good debt coverage ratio (DCR)?
Aim for 1.2 or higher — meaning rent covers 120% of total costs.
8. Can I use it for commercial properties?
Yes, if you adjust inputs for larger loans and longer terms.
9. How do property taxes affect my payment?
They add directly to your monthly escrow; vary widely by location.
10. What if I plan to refinance later?
Recalculate payments with new loan terms to see potential savings.
11. Does it show amortization schedules?
Yes — view month-by-month principal vs. interest breakdown.
12. Is interest fixed or variable?
You can model both; for variable, test high and low scenarios.
13. Does the calculator handle bi-weekly payments?
Yes — bi-weekly schedules shorten payoff time and reduce total interest.
14. Should I include maintenance or vacancy here?
Those belong in profit/cash flow calculators, not mortgage-only ones.
15. Can I estimate prepayment effects?
Yes — simulate extra monthly or yearly payments to see how fast you can pay off the loan.
16. How do closing costs fit in?
Include them in your total investment but not the mortgage principal unless financed.
17. What is amortization?
The process of paying off the loan through equal payments that gradually shift from mostly interest to mostly principal.
18. Can I use it for multi-unit buildings?
Yes — total rent and one mortgage still apply.
19. Does it show total interest paid?
Yes — displayed in summary and amortization table.
20. How often should I recalc?
Whenever interest rates, property taxes, or insurance premiums change.
