Investment Property Mortgage Calculator
An Investment Property Mortgage Calculator helps real estate investors evaluate the financial performance of rental properties. By inputting property price, down payment, interest rate, loan term, and expenses, this tool calculates monthly mortgage payments, cash flow, cap rate, and cash-on-cash return.
This allows investors to make informed decisions about potential property purchases and financing strategies.
Key Features
- Calculate loan amount and monthly mortgage payments
- Estimate total monthly expenses, including property tax, insurance, and maintenance
- Determine monthly cash flow (rental income minus expenses)
- Calculate cash-on-cash return for the investment
- Compute cap rate to evaluate property profitability
How the Calculator Works
Step 1: Enter Property Details
- Property Price – the purchase price of the property
- Down Payment (%) – the portion of the property price you will pay upfront
Step 2: Enter Loan Details
- Interest Rate (% per annum) – annual interest charged by the lender
- Loan Term (years) – total repayment period
Step 3: Enter Rental Income & Expenses
- Expected Monthly Rental Income – potential rent you can charge
- Annual Property Tax – yearly tax on the property
- Annual Insurance – property insurance cost per year
- Monthly Maintenance/HOA – ongoing maintenance or homeowner association fees
What the Calculator Outputs
- Loan Amount – total borrowed amount after down payment
- Down Payment Amount – actual cash paid upfront
- Monthly Mortgage Payment – principal + interest per month
- Total Monthly Expenses – mortgage + tax + insurance + maintenance
- Monthly Rental Income – income from tenants
- Monthly Cash Flow – rental income minus total expenses
- Cash-on-Cash Return (%) – annual cash flow relative to initial investment
- Cap Rate (%) – net operating income divided by property price

This example demonstrates how a property generates positive cash flow while providing insight into investment return metrics.
Understanding Cash Flow, Cash-on-Cash Return, and Cap Rate
Cash Flow
Cash flow shows the profitability of a property each month after all expenses.
Positive cash flow means the property earns more than it costs to maintain.
Cash-on-Cash Return
Cash-on-cash return measures annual cash income relative to the cash invested (down payment).
It helps investors compare different property investment opportunities.
Cap Rate
Cap rate is calculated as Net Operating Income ÷ Property Price.
It shows the property’s overall yield, ignoring financing. A higher cap rate typically indicates better potential returns.
Benefits of Using This Calculator

Tips for Investment Property Analysis
- Include all expenses: Don’t forget vacancies, repairs, or management fees
- Evaluate financing: Interest rates and loan terms greatly affect cash flow
- Consider long-term growth: Factor in potential property appreciation
- Use both cap rate and cash-on-cash return: They measure different aspects of performance
