The magic home loan number you need to know

We talk a lot about how important it is to find a great home loan deal, but do you really know what that means?

New research from the home loan comparison experts at Mozo reveals that 3.70% is the new benchmark for home loan rates, so if your rate is higher than this, you could be paying too much interest.

Despite the fact that half the lenders in the Mozo database currently offer an owner occupier rate at or below the magic number, many Aussies are still paying too much on their mortgage, with the average rate sitting at a steep 4.35%.

“By being on the lookout for more competitive rates under the 3.70% benchmark, borrowers have the potential to save thousands of dollars a year on their home loan,” says Mozo Director, Kirsty Lamont.

Crunching the numbers

On a $300,000 home loan over 30 years, the difference between the cost of the average home loan rate and the lowest in the Mozo database is $59,276 - a considerable chunk of change for a household to save*.

“There’s potentially tens of thousands of dollars in savings up for grabs for those who take the time to shop around and find a great deal,” said Lamont.


Tips for choosing a bargain home loan rate

  • Check the comparison rate. One really handy tool when trying to decide what the best value loan for you is, is the comparison rate. This rate takes into account both the interest and guaranteed fees on a loan, to give you a more accurate idea of the ‘true’ cost of a loan and help you compare your options on even footing.

  • Decide what you really need. Many home loans come with a bunch of handy features like free extra repayments and offset accounts which can save you a tonne of money on interest. The downside is that full feature home loans often have more fees or higher interest rates attached. So it’s worth working out exactly what features you’ll use and look for a home loan to suit, so you’re not paying for extras you don’t use.

  • Compare your options. An easy way to compare a heap of home loans from a wide array of lenders is to use our home loan comparison table. Or, if you’re refinancing, take our Switch and Save calculator for a whirl to find out how much a better deal could save you.

*Based on a $300,000 loan over 30 years, 80% LVR, principal and interest repayments. Lowest rate in the Mozo database is 3.49% from Reduce Home Loans.

* WARNING: This comparison rate applies only to the example or examples given. Different amounts and terms will result in different comparison rates. Costs such as redraw fees or early repayment fees, and cost savings such as fee waivers, are not included in the comparison rate but may influence the cost of the loan. The comparison rate displayed is for a secured loan with monthly principal and interest repayments for $150,000 over 25 years.

** Initial monthly repayment figures are estimates only, based on the advertised rate. You can change the loan amount and term in the input boxes at the top of this table. Rates, fees and charges and therefore the total cost of the loan may vary depending on your loan amount, loan term, and credit history. Actual repayments will depend on your individual circumstances and interest rate changes.
