Mortgage Repayment Calculator

Compare a repayment scenario, not a loan offer

Enter the principal you would borrow, an assumed annual interest rate and a term. The result spreads repayment into equal monthly amounts at a fixed rate.

Worked example

A $600,000 loan at 6% over 30 years gives $3,597.30 per month. The calculator assumes that rate remains unchanged for all 30 years, which is a modelling choice, not a forecast.

How the result is built

Each payment covers interest on the remaining balance and some principal. Earlier payments contain a larger interest component because the balance is higher.

Before you use the number

Deposit requirements, fees, insurance, rates, bank serviceability checks and rate changes are not included. A manageable illustrative payment is not proof of loan approval or affordability.
