What is the monthly repayment on a $600,000 Great Southern Bank home loan?
At Great Southern Bank's lowest variable rate of 6.04% p.a., a $600,000 principal and interest loan over 30 years repays about $3,613 a month, and $500,000 about $3,011. That is an estimate at the advertised rate before fees; the comparison rate in the table above carries the fees, and a fixed or interest-only loan repays differently.
How much do you need to earn for a $500,000 Great Southern Bank home loan?
There is no single salary. Like every Australian lender, Great Southern Bank must assess a new home loan at a rate at least 3 percentage points above the loan's rate under APRA's serviceability buffer, so 6.04% p.a. is assessed at about 9.04% p.a., then test that repayment against income after living expenses and other debts. The income required calculator at /calculators/income-required works this backwards from a property price and deposit.
