What is an Investment Property Loan?
An investment property loan is a type of loan used to purchase property with the intention of generating income — typically through renting, leasing, or selling at a profit. These loans often come with different interest rates, deposit requirements, and repayment terms compared to traditional owner-occupied home loans.
Understanding the terms of an investment loan is crucial, as mistakes can significantly impact your return on investment (ROI). That’s why using a reliable calculator is essential before committing to any property purchase.
How to Use the Investment Property Loan Calculator
Using our Investment Property Loan Calculator is simple and straightforward. Here’s a step-by-step guide:
- Enter Loan Amount: Input the amount you plan to borrow for your investment property.
- Enter Interest Rate: Add the annual interest rate offered by your lender (in percentage).
- Select Loan Term: Choose the duration of your loan in years (typically between 10 to 30 years).
- Choose Payment Frequency: Select how often you plan to make repayments — monthly, fortnightly, or weekly.
- Click Calculate: Instantly view your total repayments, interest paid, and monthly repayment figure.
Formula Behind the Calculator
The investment property loan calculator uses the standard loan amortization formula to determine monthly payments:
Monthly Payment (M) = P × [r(1 + r)^n] / [(1 + r)^n – 1]
Where:
- P = Principal loan amount
- r = Monthly interest rate (annual interest ÷ 12 ÷ 100)
- n = Total number of monthly payments (loan term in years × 12)
This formula ensures that the repayment estimate accounts for both interest and principal components.
Example Calculation
Scenario:
- Loan Amount: $350,000
- Interest Rate: 6.5% per annum
- Loan Term: 25 years
Using the calculator:
- Monthly Interest Rate (r) = 6.5 ÷ 12 ÷ 100 = 0.005417
- Number of Payments (n) = 25 × 12 = 300
Plugging into the formula:
- Monthly Payment = 350000 × [0.005417(1 + 0.005417)^300] / [(1 + 0.005417)^300 – 1]
- Monthly Payment ≈ $2,370.20
So, you’ll pay approximately $2,370/month, with total repayment of $711,060 over 25 years, including $361,060 in interest.
