The pros and cons of comparing fixed rate home loans

The pros and cons of comparing fixed rate home loans

Following recent cash rate cuts from the Reserve Bank of Australia (RBA), many banks have slashed their home loan interest rates to new lows.

Some borrowers may want to lock in these low rates with a fixed rate home loan, but it’s important to be aware of the potential risks and rewards involved before applying.

Pros of fixed rate home loans

The main benefit of a fixed rate home loan is that it keeps your home loan repayments the same for a pre-set length of time, for simpler budgeting. If interest rates rise, borrowers on variable rate home loans will have to pay more in interest charges, while borrowers with fixed rate loans keep paying the same amount, effectively saving some money.

For example, if you were to take out a fixed rate home loan from BOQ, you could lock in an interest rate as low as 2.99% p.a. (comparison rate 4.09% p.a.) for a term of three years. Assuming a mortgage of $500,000 for example, your repayments would cost $2,105 per month for three years, regardless of whether rates rise.

Features of fixed rate home loans

A low interest rate isn’t the only thing to look for when comparing fixed rate home loans. A mortgage with features and benefits that suit your financial situation can make a big difference.

For example, the BOQ three-year fixed rate home loan lets you make up to $5,000 in extra repayments per year, which can help to lower your loan principal, shrink your interest charges, and pay off your debt that little bit sooner.

However, this mortgage offer is only available to owner occupiers, so investors may want to look further afield.

Cons of fixed rate home loans

The main risk of a fixed rate home loan is related to its main benefit – if variable rates change, you’ll keep paying the same fixed rate, even if a fixed rate is higher. For example, if the RBA cuts the cash rate again, or if your lender reduced its variable rates for other reasons, borrowers with fixed-rate home loans would miss out on the interest savings from the lower variable rate.

It’s also important to keep in mind that once the fixed term expires, your home loan will revert to your lender’s standard variable rate. If this rate has risen significantly during the fixed term, you could be in for a shock when the cost of your repayments jumps overnight.

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 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.

What is a fixed home loan?

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.

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.

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 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 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.

Are fixed rates or variable rates cheaper?

Fixed and variable home loan interest rates are discretionary based on the lender’s decision. They will also be influenced by the Australian economy, as well as the Reserve Bank of Australia’s cash rate. The specific interest rate you may be offered will also depend on your credit history and financial situation.

Whether a fixed or variable rate home loan is the cheaper option for you will depend on all the above, and may still fluctuate over a 25-year home loan term. Therefore, it’s worth comparing your loan options with our comparison tables to see how the rates compare, based on your specific financial needs.

What is the difference between a fixed rate and variable rate?

A variable rate can fluctuate over the life of a loan as determined by your lender. While the rate is broadly reflective of market conditions, including the Reserve Bank’s cash rate, it is by no means the sole determining factor in your bank’s decision-making process.

A fixed rate is one which is set for a period of time, regardless of market fluctuations. Fixed rates can be as short as one year or as long as 15 years however after this time it will revert to a variable rate, unless you negotiate with your bank to enter into another fixed term agreement

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 however fixed rates do offer customers a level of security by knowing exactly how much they need to set aside each month.

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*

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).

Is the lowest home loan rate always the cheapest?

The home loan with the lowest interest rate may not always be the cheapest mortgage option for you. Sometimes a home loan with a low interest rate may charge high fees, which may cost more in total than a mortgage with a higher interest rate and no fees.

Consider checking the comparison rate, which combines interest and standard fees, to get a better idea of the overall cost of different home loan options.

What is a honeymoon rate and honeymoon period?

Also known as the ‘introductory rate’ or ‘bait rate’, a honeymoon rate is a special low interest rate applied to loans for an initial period to attract more borrowers. The honeymoon period when this lower rate applies usually varies from six months to one year. The rate can be fixed, capped or variable for the first 12 months of the loan. At the end of the term, the loan reverts to the standard variable rate.
