Aussie homeowners may have to spend an extra $107,500 on their mortgage after interest rates hikes in the past year.

New research from banks revealed mortgagees will pay an additional $3586 a year on their home loan repayments after the typical variable interest rate rose from 6 per cent to 6.27 per cent in the last 12 months.

The average loan size also increased from $547,696 to $581,467, according to the Reserve Bank of Australia (RBA).

And with a typical 30-year mortgage, this adds up to a whopping $107,500 more in interest over the lifetime of the home loan.

Last year, Queensland homeowners were spending $2879 a month to service their mortgage, but now were paying $3291 — an extra $412 a month, the biggest jump of any state and territory.

Northern Territory mortgagees only need to fork out at extra $15 a month after their average monthly home loan repayments rose from $2432 to $2446 in the past year.

Western Australia, South Australia, and New South Wales property owners are paying $335 or more a month on their loan commitments, whereas Victoria, ACT and Tasmania are having to fund an extra $109-$172 a month.
