Would you give up your morning cup of coffee if you knew it could saving you more than A$70,000 ($74,126)?
According to RateCity.com.au, by giving up one coffee a day and putting the money into your mortgage you could be A$71,891 better off over the lifetime of the loan, or 30 years.
Sally Tindall from RateCity told the Queensland Times that most people have no idea how much of an impact extra repayments can have on your mortgage.
"We wanted to show that if you squirrel away a small amount each week, it can knock years off your loan. It's also something most of us can easily do with very little effort," she said.
"Buying an extra cup of coffee or a bottle of water is often just mindless spending. If you save that money you'll be shocked by the results."
