Frequently Asked Questions

The calculator uses a standard amortisation formula that accounts for your loan amount, interest rate, and loan term. It divides total interest across each monthly payment so you pay a blend of principal and interest every month, with the interest portion decreasing over time.
With principal & interest (P&I) you pay down both the loan balance and the interest each month, building equity faster. With interest-only you pay just the interest for a set period (typically 1-5 years), keeping repayments lower initially but not reducing the loan balance.
This calculator estimates repayments based on the loan amount and interest rate only. It does not include establishment fees, ongoing account fees, lender mortgage insurance (LMI), or government charges. Speak with us for a full cost breakdown tailored to your situation.
Even small additional payments can dramatically reduce total interest and shorten your loan term. For example, an extra $200 per month on a $500,000 loan at 6% could save over $100,000 in interest and cut years off your mortgage.
