Types of home loan repayments

There are many different types of home loans in Australia, but only two mortgage repayment options.

When you take out a home loan, you can choose to pay back both the interest and loan principal, or the interest only. 

It's important to understand how these different home loan repayment options work before taking out a mortgage. 

What is principal, and what is interest?

The loan principal is the amount of money you borrow. Interest is the cost you pay the lender to take out a loan. The sum of interest you pay depends on the principal and loan term, interest rates and other details.

What are the two home loan repayment options?

Principal and interest loan

With a principal and interest loan, your regular repayments are applied to both the loan's principal and interest.

When you start making repayments, most of your money will go towards the loan's interest. After a while, more of your monthly repayment will go towards the principal instead of interest. As you gradually pay the principal portion, the interest on that principal amount will also go down. 

Advantages

  • You'll pay less interest over the life of the loan
  • Interest rates may be lower than an interest only loan
  • You can pay off your home faster

Disadvantages

  • Monthly repayments will be higher
  • You may miss out on tax benefits if you have an investment loan
Most people opt for principal and interest mortgage repayments.

Interest only loan

For a set period, your repayments only go towards the interest on your loan, and not the loan principal amount. This can be up to 3 years for an owner-occupied loan and up to 5 years for an investment loan. 

You'll need a credit assessment to apply for an interest only loan. 

Advantages

  • Repayments are lower during the interest only period
  • It could be easier for you to manage your cash flow
  • You may be able to extend the interest only period if you meet the eligibility requirements

Disadvantages

  • It could cost you more in the long run
  • Monthly mortgage repayments will be higher once the interest only period ends – you'll be repaying both the principal and interest, recalculated for the remaining loan term
  • It can be more difficult to get approved for an interest only loan

Comparing mortgage repayments by home loan type

The type of loan you take out will affect your repayments. See how much interest you'd pay on the same loan over 30 years.

Although interest only loans usually have a higher interest rate, we're using the same rate for comparison purposes: 

Principal and interest vs interest only home loans
Loan terms Principal and interest Interest only (3 years)
Loan amount $600,000 $600,000
Interest rate 6.0% 6.0%
Repayments - interest only period Not applicable $3,000
Repayments - principal and interest $3,598 $3,741
Total interest payable $695,030 $719,815
Principal and interest vs interest only home loans
Loan terms Loan amount Loan amount
Principal and interest $600,000 $600,000
Interest only (3 years) $600,000 $600,000
Loan terms Interest rate Interest rate
Principal and interest 6.0% 6.0%
Interest only (3 years) 6.0% 6.0%
Loan terms Repayments - interest only period Repayments - interest only period
Principal and interest Not applicable Not applicable
Interest only (3 years) $3,000 $3,000
Loan terms Repayments - principal and interest Repayments - principal and interest
Principal and interest $3,598 $3,598
Interest only (3 years) $3,741 $3,741
Loan terms Total interest payable Total interest payable
Principal and interest $695,030 $695,030
Interest only (3 years) $719,815 $719,815

In this example, you'd save an estimated $24,785 in interest by making principal and interest repayments.
