Understanding the impact of home loan interest rates

Understanding the impact of home loan interest rates

We all understand the importance of finding a lender offering competitive interest rates when entering into a home loan however there are other factors you need to consider including, comparison rates, fees and charges.

While it’s not the only thing you want to think about for your home loan, it’s natural and important that you compare interest rates between the different home loan options you’re considering. Remember that interest will be the biggest single cost you face – a $400,000 home loan with a 6.5 percent interest rate will cost you over $400,000 in interest over 25 years!

When you compare interest rates on home loans, you will generally see two rates. The first is the “headline” or advertised rate. Most lenders advertise this rate, and it’s the one that you’ll pay on your debt on day one. But it’s not sufficient to fully understand the cost of the loan.

That’s why there is a second, and perhaps more important interest rate you need to look at, called the comparison rate.

What is a comparison rate?

In order to compare interest rates and fees, the government developed the concept of the comparison rate some years ago. It’s designed to help you understand the “true cost” of a loan. It does this by looking at most of the fees and charges that apply to a loan, and then assuming a loan of $150,000. That way, you can compare interest rates across very different loans.

As an example, a loan with a very low headline rate – say 6 percent – might look really attractive when compared to one with a headline rate of 6.5 percent. But if the 6 percent loan has a $500 per year fee, then it may end up being just as expensive, especially if the 6.5 percent rate doesn’t have recurring fees. In this case, the comparison rate will be a reasonably accurate guide to help you compare interest rates more accurately between the two loans.

Ask your lender about revert rates

Comparison rates aren’t perfect. For example, they don’t work very well when comparing a fixed rate loan to a variable, because it assumes you automatically get the revert rate when the fixed period ends. However a lot of fixed loans revert to a higher interest rate at the end of the fixed term.

In fact, most people refinance to another fixed rate or a better variable rate home loan. However, when you want to compare interest rates, it’s a reasonable tool to put two loans side by side, so you should always look at the comparison rate as well as the headline rate.

Use the RateCity mortgage repayment calculator to compare home loans so you can quickly spot and eliminate the home loans that will empty your pockets out sooner.

What is a comparison rate?

The comparison rate is a more inclusive way of comparing home loans that factors in not only on the interest rate but also the majority of upfront and ongoing charges that add to the total cost of a home loan.

The rate is calculated using an industry-wide formula based on a $150,000 loan over a 25-year period and includes things like revert rates after an introductory or fixed rate period, application fees and monthly account keeping fees.

In Australia, all lenders are required by law to publish the comparison rate alongside their advertised rate so people can compare products easily.

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. 

What happens to my home loan when interest rates rise?

If you are on a variable rate home loan, every so often your rate will be subject to increases and decreases. Rate changes are determined by your lender, not the Reserve Bank of Australia, however often when the RBA changes the cash rate, a number of banks will follow suit, at least to some extent. You can use RateCity cash rate to check how the latest interest rate change affected your mortgage interest rate.

When your rate rises, you will be required to pay your bank more each month in mortgage repayments. Similarly, if your interest rate is cut, then your monthly repayments will decrease. Your lender will notify you of what your new repayments will be, although you can do the calculations yourself, and compare other home loan rates using our mortgage calculator.

There is no way of conclusively predicting when interest rates will go up or down on home loans so if you prefer a more stable approach consider opting for a fixed rate loan.

Does the Home Loan Rate Promise apply to discounted interest rate offers, such as honeymoon rates?

No. Temporary discounts to home loan interest rates will expire after a limited time, so they aren’t valid for comparing home loans as part of the Home Loan Rate Promise.

However, if your home loan has been discounted from the lender’s standard rate on a permanent basis, you can check if we can find an even lower rate that could apply to you.

What is the difference between fixed, variable and split rates?

Fixed rate

A fixed rate home loan is a loan where the interest rate is set for a certain amount of time, usually between one and 15 years. The advantage of a fixed rate is that you know exactly how much your repayments will be for the duration of the fixed term. There are some disadvantages to fixing that you need to be aware of. Some products won’t let you make extra repayments, or offer tools such as an offset account to help you reduce your interest, while others will charge a significant break fee if you decide to terminate the loan before the fixed period finishes.

Variable rate

A variable rate home loan is one where the interest rate can and will change over the course of your loan. The rate is determined by your lender, not the Reserve Bank of Australia, so while the cash rate might go down, your bank may decide not to follow suit, although they do broadly follow market conditions. One of the upsides of variable rates is that they are typically more flexible than their fixed rate counterparts which means that a lot of these products will let you make extra repayments and offer features such as offset accounts.

Split rates home loans

A split loan lets you fix a portion of your loan, and leave the remainder on a variable rate so you get a bet each way on fixed and variable rates. A split loan is a good option for someone who wants the peace of mind that regular repayments can provide but still wants to retain some of the additional features variable loans typically provide such as an offset account. Of course, with most things in life, split loans are still a trade-off. If the variable rate goes down, for example, the lower interest rates will only apply to the section that you didn’t fix.

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.

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. 

What is a variable home loan?

A variable rate home loan is one where the interest rate can and will change over the course of your loan. The rate is determined by your lender, not the Reserve Bank of Australia, so while the cash rate might go down, your bank may decide not to follow suit, although they do broadly follow market conditions. One of the upsides of variable rates is that they are typically more flexible than their fixed rate counterparts which means that a lot of these products will let you make extra repayments and offer features such as offset accounts.

How long can you fix a home loan rate for?

Most lenders should let you fix your interest rate for anywhere between one and five years. While rare, a few lenders may offer fixed rate terms for as long as 10 years.

Fixing your home loan interest rate for a longer term can keep your budgeting fairly straightforward, as you shouldn't have to factor in changes to your mortgage repayments if variable rates change, such as when the Reserve Bank of Australia (RBA) changes its rates at its monthly meeting. Additionally, if variable rates rise during your fixed rate term, you can continue to pay the lower fixed rate until the fixed term ends, potentially saving you some money.

Of course, a longer fixed term also means a longer length of time where you may have less flexibility in your home loan repayments. It’s also a longer period where you won’t be able to refinance your mortgage without paying break fees. If variable rates were to fall during this period, you may also be stuck paying a higher fixed rate for a longer period.

What is a standard variable rate (SVR)?

The standard variable rate (SVR) is the interest rate a lender applies to their standard home loan. It is a variable interest rate which is normally used as a benchmark from which they price their other variable rate home loan products.

A standard variable rate home loan typically includes most, if not all the features the lender has on offer, such as an offset account, but it often comes with a higher interest rate attached than their most ‘basic’ product on offer (usually referred to as their basic variable rate mortgage).

What is the average annual percentage rate?

Also known as the comparison rate, or sometimes the ‘true rate’ of a loan, the average annual percentage rate (AAPR) is used to indicate the overall cost of a loan after considering all the fees, charges and other factors, such as introductory offers and honeymoon rates.

The AAPR is calculated based on a standardised loan amount and loan term, and doesn’t include any extra non-standard charges.

What is the Home Loan Rate Promise?

The Home Loan Rate Promise is RateCity putting its money where its mouth is. We believe that too many Australians are paying too much for their home loans. We’re so confident we can help Aussies save money, if we can’t beat your current rate, we’ll give you a $100 gift card.*

There are two reasons it pays to check your rate with the Home Loan Rate Promise:

  • You can find out how much you could save on your home loan by switching to a loan with a lower interest rate
  • If we can’t beat your current rate, you can claim a $100 gift card with our Home Loan Rate Promise*

How does ANZ calculate early repayment costs?

If you have a fixed interest home loan, you’ll pay ANZ home loan early exit fees for partial or full repayment of the loan amount before the end of the fixed interest rate duration. These fees are also payable if you switch to another variable or fixed-rate loan.

The ANZ mortgage early exit fees can vary and you can get an estimate from the lender before you decide to prepay the loan. However, the exact early repayment cost can be determined when you prepay the loan.

The early exit fees are calculated after considering factors like the prepayment amount, the period left before the fixed-rate duration ends, and the change in the market rates since the beginning of the fixed-rate period. The early exit fees may not be charged if you’re paying off a smaller amount. You can check with ANZ to see how much you’ll have to pay.

How do you determine which home loan rates/products I’m shown?

When you check your home loan rate, you’ll supply some basic information about your current loan, including the amount owing on your mortgage and your current interest rate.

We’ll compare this information to the home loan options in the RateCity database and show you which home loan products you may be eligible to apply for.
