If you’ve found yourself scratching your head trying to figure out all the different types of interest rates and how they affect your mortgage repayments, you’re not alone. With debates about whether you should go for a fixed or variable interest rate, and terms like split rate thrown in, it’s almost easier to just agree with whatever your lender tells you to take. However, knowing the difference between each interest rate type could mean saving heaps over the life of your loan. 

Whether you’re new to the property world, looking to buy your first home or are interested in refinancing, read on to find out:

  • The benefits of knowing the ins and outs of rate types
  • Why timing is important when it comes to choosing a fixed rate 
  • The pros and cons of choosing a variable interest rate
  • What a split rate is and how it offers you the best of both (interest) worlds
  • What to consider when choosing a rate type

In the frenzy of buying their first home, people often overlook the terms and conditions of their home loan. For instance, that their interest rate changes after the first year of their loan. Lenders attract buyers with low offers, highlighting how you might save in the first year. But, did you know that without calculating the amount you pay in interest over time and comparing it to other interest rates on offer, you could be missing out? 

Couple this with certain features offered when you choose a select interest rate type and the amount of interest you pay could prove staggering in the long run. Not only could you accidentally prolong your loan term but you could also be paying more than you should be. 

Here’s a breakdown of the differences between each rate and product type, and the benefits or drawbacks of each:

What is a fixed rate?

A fixed rate is when the interest rate you pay for a certain period of time becomes set (fixed) at the initial rate you and your lender agreed on. This period usually lasts for a few years. As such, even if market conditions or the Reserve Bank’s cash rate change, the interest you pay on your home loan will stay constant. 

Thus, you will always know how much of your repayment is going towards paying for the principal amount of your home loan, and how much is going towards interest. While this protects you from sudden interest rate hikes, it also means you can’t take advantage of interest rate drops. This is because your lender may also charge you for making extra repayments. Furthermore, they will also prevent you from using features like an offset account. Generally, most lenders offer a lower fixed rate for the initial period of your loan. Usually, it’s about one to two years before switching back to a variable interest rate. 

If possible, opt to lock in an interest rate when the rate is at its lowest and is about to improve. As such, you can make the most of a fixed interest rate,

What is a variable rate?

A variable interest rate home loan means that you’ve been paying varying amounts of interest throughout your loan term. While you still make the same repayment amounts every month, the amount that goes towards interest and the amount that goes towards paying off your actual home differs every time the interest rate changes.

The interest rate fluctuates depending on various factors and the decision your lender decides to make. While the rate you pay isn’t determined by market conditions explicitly, most lenders follow current conditions. This means that if the Reserve Bank of Australia lowers the cash rate, your interest rate might go down too. Since there is more fluctuations to your interest rates, your lender might offer you offset or redraw features. Additionally, they might even offer the ability to make extra repayments at no cost. Depending on your income and how much free cash flow you have monthly, this could be beneficial to your situation. 

The main benefit is that in a down market you could be saving thousands in interest annually. This is due to the interest rate continues to collectively drop. 

What is a split rate? 

If you’re on a split loan, you’ll most likely reap the benefits of having both interest rate types simultaneously. How? Essentially, on a split rate loan, you’ll be paying a fixed rate on a portion of your loan, and a variable rate on the rest of it. This means you’ll be subject to the cons of each rate type, you’ll also be getting the best of both worlds:

  • Assurance that your repayments will definitely be going towards your home loan
  • The ability to use the banking features that variable loans offer

As beneficial as it seems, it is still something that should be carefully considered. You might be paying more interest on the variable part if you opt for a split rate. On the flipside, if the interest rate lowers drastically, you pay more on the fixed interest portion of your loan. 

If you’re still interested in having your mortgage on a split interest rate, make sure to ask your lender whether or not you’re able to add the split rate feature to your home loan product. It is also important to keep in mind that there’s no definitive rule for splitting your home loan. Hence, you can choose which way to split your loan and which portion you wish to keep fixed and variable. 

Where to from here?

As always, choosing the right interest rate type for you depends on your current situation. Making the switch could mean the difference between spending thousands of dollars, or saving it.

Similarly, if you’re looking to save for down the track, pay off your home loan as fast as possible, knowing how much you’ll be spending down the track based on any of your options could be beneficial. Lastly, it’s always important to know where the property cycle and market is currently at. If the market has begun to slow down and interest rates seem like they’ll continue to fall, it may be best to wait a little longer before locking in a fixed rate or refinancing to change your current rate type. Similarly, if the housing market is in a boom phase it might be beneficial to lock in a fixed or split rate as soon as possible to reap the benefits of a lower interest rate for a few more years.
