1. What is the Home Loan Payment Formula?

The home loan payment formula calculates the fixed monthly payment required to repay a loan over its term. It accounts for the principal amount, interest rate, and loan duration to determine consistent payments.

2. How Does the Calculator Work?

The calculator uses the standard PMT formula:

Where:

• \( P \) — Principal loan amount (AUD)
• \( r \) — Monthly interest rate (annual rate ÷ 12)
• \( n \) — Total number of payments (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 covers both principal and interest.
