1. What is the Monthly Payment Formula?

The monthly payment formula calculates the fixed payment amount required to repay a loan over a specified term, including both principal and interest components. Westpac Bank currently offers home loan rates starting at 6.74%.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

Where:

• \( P \) — Principal loan amount (AUD)
• \( r \) — Monthly interest rate (annual rate ÷ 12)
• \( n \) — Total number of payments (loan term in years × 12)
• \( PMT \) — Monthly payment amount (AUD)

Explanation: The formula accounts for compound interest over the life of the loan, calculating a fixed payment that will completely pay off the loan by the end of the term.

3. Importance of Monthly Payment Calculation

Details: Understanding your monthly payment helps with budgeting and ensures you can comfortably afford your home loan. It also helps compare different loan options.

4. Using the Calculator

Tips: Enter the principal amount in AUD, annual interest rate (Westpac's current rate is pre-filled), and loan term in years. All values must be positive numbers.
