What is a principal and interest home loan?

If you’re in the market for a new home loan, or if you are refinancing an existing home loan, it is important to understand how you intend to repay your mortgage. 

Repayments are either made on a ‘principal and interest’ basis or they are paid by ‘interest-only’ instalments. 

Principal and interest loans

Making principal and interest (P&I) repayments helps to trim the principal (or ‘capital’), as well as the mortgage interest on the home loan. This is a popular choice for owner-occupiers. 

A P&I loan can be a competitive choice if you intend to live in the property for a long time. By paying off the capital, you not only increase your own equity stake in the property, but this strategy will result in outright home ownership. 

As you pay down the principal, you’ll simultaneously help to reduce the interest you’ll pay over the term of the loan. However, if you select a P&I option, your monthly repayments will be higher than if you make interest-only payments. 

Interest-only loans 

As the name would suggest, with an interest-only loan you only pay the mortgage interest set by the lender. This means you don’t repay any capital. 

Most lenders offer interest-only loans for a limited time – up to 5 years in some cases – after which you either need to start paying back the principal, or you must reapply to continue paying the home loan on an interest-only basis. 

Many investors choose interest-only loans as they can pay less in mortgage repayments and can easily work out a tax deductable amount to claim. First home buyers may find this an attractive loan type, particularly after the shock of initial buying expenses.

APRA crackdown on interest-only lending

Recently, lenders have been increasing interest rates for interest-only loans and the requirements to have one have become much harder (if the option hasn’t been removed completely). This is a result of a recent crackdown by APRA on risky lending practices.

 

It is important you look at the comparison rates of interest-only vs. principal and interest loans for this reason, as the money you save paying interest soon may not stack up as rates continue to rise.

How they stack up

Example – owner-occupier Alex has taken out a $350,000 home loan at a rate of 5 per cent interest over a term of 25 years. 

If she took out a P&I Loan for the whole loan term: 

Monthly repayments $2,046
Total cost of loan $613,820

If she took out a five-year interest-only loan, and then swapped to paying P&I: 

Monthly repayments (five-years interest-only) $1,458
Monthly repayments (20-years P&I) $2,310
Total cost of loan $641,863

Paying the principal and interest option will set Alex back around $2,046 per month, while the interest only option might seem more affordable at around $1,458 per month for the first five years. 

However, once that interest-only period finishes Alex will be left paying principal and interest on a 20-year loan term, which is almost $300 more expensive per month and costs her an extra $28,043 over the life of the loan. 

How do I know which is the best home loan for me? 

Choosing between principal and interest or interest-only loans is a personal decision that comes down to individual factors, including whether you’re an owner-occupier, whether you’re concerned about finances etc. 

Try using our home loan calculator to estimate your repayments and determine the total amount of interest payable over the lifetime of the loan. This should help you to determine if you can afford to pay both principal and interest.

What is an interest-only loan? How do I work out interest-only loan repayments?

An ‘interest-only’ loan is a loan where the borrower is only required to pay back the interest on the loan. Typically, banks will only let lenders do this for a fixed period of time – often five years – however some lenders will be happy to extend this.

Interest-only loans are popular with investors who aren’t keen on putting a lot of capital into their investment property. It is also a handy feature for people who need to reduce their mortgage repayments for a short period of time while they are travelling overseas, or taking time off to look after a new family member, for example.

While moving on to interest-only will make your monthly repayments cheaper, ultimately, you will end up paying your bank thousands of dollars extra in interest to make up for the time where you weren’t paying off the principal.

What is 'principal and interest'?

‘Principal and interest’ loans are the most common type of home loans on the market. The principal part of the loan is the initial sum lent to the customer and the interest is the money paid on top of this, at the agreed interest rate, until the end of the loan.

By reducing the principal amount, the total of interest charged will also become smaller until eventually the debt is paid off in full.

When does Commonwealth Bank charge an early exit fee?

When you take out a fixed interest home loan with the Commonwealth Bank, you’re able to lock the interest for a particular period. If the rates change during this period, your repayments remain unchanged. If you break the loan during the fixed interest period, you’ll have to pay the Commonwealth Bank home loan early exit fee and an administrative fee.

The Early Repayment Adjustment (ERA) and Administrative fees are applicable in the following instances:

  • If you switch your loan from fixed interest to variable rate
  • When you apply for a top-up home loan
  • If you repay over and above the annual threshold limit, which is $10,000 per year during the fixed interest period
  • When you prepay the entire outstanding loan balance before the end of the fixed interest duration.

The fee calculation depends on the interest rates, the amount you’ve repaid and the loan size. You can contact the lender to understand more about what you may have to pay. 

How can I calculate interest on my home loan?

You can calculate the total interest you will pay over the life of your loan by using a mortgage calculator. The calculator will estimate your repayments based on the amount you want to borrow, the interest rate, the length of your loan, whether you are an owner-occupier or an investor and whether you plan to pay ‘principal and interest’ or ‘interest-only’.

If you are buying a new home, the calculator will also help you work out how much you’ll need to pay in stamp duty and other related costs.

How do I calculate monthly mortgage repayments?

Work out your mortgage repayments using a home loan calculator that takes into account your deposit size, property value and interest rate. This is divided by the loan term you choose (for example, there are 360 months in a 30-year mortgage) to determine the monthly repayments over this time frame.

Over the course of your loan, your monthly repayment amount will be affected by changes to your interest rate, plus any circumstances where you opt to pay interest-only for a period of time, instead of principal and interest.

What is the average length of a home loan?

Most Aussie lenders offer home loans with a 30-year term, meaning that you should pay back the full loan amount and the interest you owe on the amount in 30 years. 

However, home loans can also have a shorter or longer term. They may be as low as ten years or up to 45 years, depending on the product and lender. 

It’s worth remembering that a longer loan term usually means you’ll end up paying a lot more interest in total, but your scheduled repayments may be more manageable. In contrast, you could opt for a shorter loan term if you are comfortable making large repayments in exchange for paying less interest over the term of the loan.

What are the different types of home loan interest rates?

A home loan interest rate is used to calculate how much you’ll pay the lender, usually annually, above the amount you borrow. It’s what the lenders charge you for them lending you money and will impact the total amount you’ll pay over the life of your home loan. 

Having understood what are home loan rates in general, here are the two types you usually have with a home loan:

Fixed rates

These interest rates remain constant for a specific period and are a good option if you’re a first-time buyer or if you’re looking for a fixed monthly repayment. One possible downside of a fixed rate is that it may be higher than a variable rate. Also, you don’t benefit from any lowering of interest rates in the market. On the flip side, if rates go up, your rate won’t change, possibly saving you money.

Variable rates

With variable interest rates, the lender can change them at any time. This change can be based on economic conditions or other reasons. Changes in interest rates could be beneficial if your monthly repayment decreases but can be a problem if it increases. Variable interest rates offer several other benefits often not available with fixed rate home loans like redraw and offset facilities and free extra repayments. 

How can I pay off my home loan faster?

The quickest way to pay off your home loan is to make regular extra contributions in addition to your monthly repayments to pay down the principal as fast as possible. This in turn reduces the amount of interest paid overall and shortens the length of the loan.

Another option may be to increase the frequency of your payments to fortnightly or weekly, rather than monthly, which may then reduce the amount of interest you are charged, depending on how your lender calculates repayments.

What are extra repayments?

Additional payments to your home loan above the minimum monthly instalments, which can help to reduce the loan’s term and remaining payable interest.

What is the best interest rate for a mortgage?

The fastest way to find out what the lowest interest rates on the market are is to use a comparison website.

While a low interest rate is highly preferable, it is not the only factor that will determine whether a particular loan is right for you.

Loans with low interest rates can often include hidden catches, such as high fees or a period of low rates which jumps up after the introductory period has ended.

To work out the best value for money, have a look at a loan’s comparison rate and read the fine print to get across all the fees and charges that you could be theoretically charged over the life of the loan.

What are the features of home loans for expats from Westpac?

If you’re an Australian citizen living and working abroad, you can borrow to buy a property in Australia. With a Westpac non-resident home loan, you can borrow up to 80 per cent of the property value to purchase a property whilst living overseas. The minimum loan amount for these loans is $25,000, with a maximum loan term of 30 years.

The interest rates and other fees for Westpac non-resident home loans are the same as regular home loans offered to borrowers living in Australia. You’ll have to submit proof of income, six-month bank statements, an employment letter, and your last two payslips. You may also be required to submit a copy of your passport and visa that shows you’re allowed to live and work abroad.

How does a mortgage calculator work?

A mortgage calculator is an extremely helpful tool when planning to take out a home loan and working out the costs. Although each mortgage calculator you come across may be slightly different, most will help you estimate how much your repayments will be. The calculator will often also show you the difference in repayments if you repay weekly, monthly or fortnightly. 

To calculate these figures, you’ll be asked to enter a few details. These include the amount you plan to borrow, whether you’re an owner-occupier or an investor, the proposed interest rate and the home loan term. It will also often show you the total interest you’ll be charged and the total amount you’ll repay over the life of the loan.  

Understanding how the mortgage calculator works, helps you to use it to see how different loan amounts, interest rates and terms affect your repayments. This can then help you choose a home loan that you can repay comfortably and save on interest costs. The mortgage calculator lets you compare the benefits and costs of home loans from different lenders to help you make a more informed choice. Use a mortgage calculator to help identify which home loan is most suitable for your requirements and financial situation.

Why does Westpac charge an early termination fee for home loans?

The Westpac home loan early termination fee or break cost is applicable if you have a fixed rate home loan and repay part of or the whole outstanding amount before the fixed period ends. If you’re switching between products before the fixed period ends, you’ll pay a switching break cost and an administrative fee. 

The Westpac home loan early termination fee may not apply if you repay an amount below the prepayment threshold. The prepayment threshold is the amount Westpac allows you to repay during the fixed period outside your regular repayments.

Westpac charges this fee because when you take out a home loan, the bank borrows the funds with wholesale rates available to banks and lenders. Westpac will then work out your interest rate based on you making regular repayments for a fixed period. If you repay before this period ends, the lender may incur a loss if there is any change in the wholesale rate of interest.

Cash or mortgage – which is more suitable to buy an investment property?

Deciding whether to buy an investment property with cash or a mortgage is a matter or personal choice and will often depend on your financial situation. Using cash may seem logical if you have the money in reserve and it can allow you to later use the equity in your home. However, there may be other factors to think about, such as whether there are other debts to pay down and whether it will tie up all of your spare cash. Again, it’s a personal choice and may be worth seeking personal advice.

A mortgage is a popular option for people who don’t have enough cash in the bank to pay for an investment property. Sometimes when you take out a mortgage you can offset your loan interest against the rental income you may earn. The rental income can also help to pay down the loan.
