How Home Loan Repayments Work
Home loan repayments are typically calculated using a standard amortisation formula. With Principal & Interest (P&I) repayments, each payment covers both the interest charge and a portion of the loan balance. Early payments are mostly interest; as the balance decreases, more of each payment goes toward the principal.
With Interest-Only repayments, you only pay the interest charge each month. Your loan balance stays the same during the interest-only period, which typically lasts 1–5 years. After this period, you switch to P&I repayments - often at a higher amount since you have less time to repay the principal.
This calculator provides estimates for general information purposes only. Actual repayments may vary based on your lender's fees, rate changes, and specific loan terms. Always refer to your loan contract for exact figures.
