What is a split home loan? 

A split rate home loan isn’t actually a specific type of home loan, but rather a type of home loan interest rate. Where most home loans are either variable or fixed-rate, split home loans use both of these types of interest rates. 

With a split rate home loan, you essentially split your home loan balance into two different accounts – one being charged a fixed interest rate and one charged a variable rate – at different portions.

For example, you might opt for a 60:40 split rate loan, where 60% of your loan is set to the loan’s standard variable rate while the remainder is set to a lower fixed rate for the first five years or so. 

If, in the above example, you took out a loan of $500,000, a 60:40 split loan would mean $300,000 would have a variable interest rate while the remaining $200,000 would attract the fixed rate. Capiche? 

If you’re not sure what split ratio you should do, a good financial adviser or mortgage broker may be able to help you figure it out. 

Calculating repayments on a split home loan

Using a split loan calculator, here’s a look at how different split loan rations can affect your total monthly repayments. For this example, we’ve used a 30-year, principal and interest (P&I) loan for $500,000.

The fixed interest rate here is a 3.00% for a period of five years, while the variable-rate will change so you can see the difference. 

Variable rate 60:40 split  70:30 split  80:20 split
3.15% p.a.  Monthly repayments (over 5-year fixed period): $2,132
Total interest payable (over 30 years): $271,852
Monthly repayments (over 5-year fixed period): $2,136
Total interest payable (over 30 years): $272,271

There’s no definitive rule on how much you can split your home loan by – it’ll be up to both you and your lender. Just make sure you consider: 

  • If your financial circumstances are likely to change in the near future 
  • What you prefer in a home loan – do you want short-term stability? Useful features like offset accounts and redraw facilities? 

Of course, your lender has to allow split loans in the first place. 

Advantages of split home loans

Splitting your home loan means you can take advantage of the benefits of both types of rates. In a low interest rate environment, having more of your loan as a variable-rate means you could potentially reap the rewards of falling interest rates, while fixing a greater portion of the loan could be more beneficial if interest rates were to rise. 

Other benefits include:

  • Security of a fixed-rate: fixing part of your loan gives you a degree of interest-rate certainty – the more you fix, the more rate security you’ll have over the length of the fixed-term, plus you can save on interest if interest rates rise. 
  • The flexibility of a variable rate: having a portion on a variable rate gives you a degree of loan flexibility (e.g. can make additional repayments, change repayment frequency, use an offset account etc.), plus you can save on interest if interest rates fall.   
  • Adjustable to your preferences: if you’re more risk-averse you can opt for a 50:50 loan split, or if you’re feeling bold why not go for something like 80:20 variable? 
  • Additional features: split home loans allow you to have a fixed home loan while also accessing features commonly associated with variable loans, like full offset accounts and redraw facilities.  

Disadvantages of split home loans

One of the main disadvantages is, as mentioned above, split home loans aren’t a specific type of home loan. To split your loan, the loan itself needs to offer a split facility as a feature, which many (but not all) home loans do.

Search for home loans that offer a split facility, and if they don’t, you can always try asking the lender to make an exception, although they’d be under no obligation to accept your request. Other potential disadvantages include:

  • Switching can be harder: since part of your loan is fixed, it could come with an expensive break fee, which would make switching harder if done before the fixed-term ends.
  • Budgeting can also be harder: having two separate mortgage repayments of differing amounts coming out of your account can make things complicated for your budgets, especially if the payment dates are different.   
  • Rates rising/falling can leave you worse off: if you get the wrong split allocation, then a rise or fall in interest rates could really leave you in the lurch.
  • More fees: since you’ve essentially split your mortgage into two separate accounts, you’ll probably pay twice as much in account-keeping fees. Also, as mentioned earlier, you’ll be up for break fees if you decide to switch or pay off the loan before the end of the fixed-term. 
  • Less choice: not all lenders offer split loan facilities. They’re not an uncommon product, but getting one can be harder in the first place, leaving you with fewer options 

If you’re currently stuck with a home loan that doesn’t offer a split facility and you want to split your loan, you could try refinancing to a loan that does. Just make sure you weigh up all the costs of refinancing against how much you could save with a split loan.

Split loans vs variable and fixed home loans 

To quickly recap, variable rate loans change based on market forces, while fixed loans are locked in for a set period of time, usually up to five years. If interest rates are expected to fall in the future, new fixed home loan rates can be lower than the variable rates on offer at the time.

For example, many lenders are now offering rates below 2.00% p.a. for fixed loans. However, fixed rates typically revert to the lender’s standard variable rate at the end of the fixed-rate period, and these revert rates can be more than 200 basis points (2.00%) higher than some of the lender’s lowest variable rates. 

Don’t assume a split home loan will always be better than a fully variable or fixed loan because anything can happen. 2020 saw a seismic shift in mortgage lending in Australia - previously fixed loans made up less than one sixth of all new home loans, and in 2021 at one stage made up nearly half of all new loans written.

This was due to various market forces, and while we're in a low interest environment now, that could change in the coming years. Fixed home loan rates are generally on the way back up, while variable rates remain untouched - even trending down in some cases.

Having a fully variable interest rate could, in theory, work out to be cheaper than having a partially variable loan. Likewise, you could be better off going full-fixed if interest rates rise in the near future, as fixed loans lock that rate in for a number of years.

Split loans vs variable loan repayments 

Split loans can sometimes be cheaper than using just a variable or fixed loan thanks to that ‘best of both worlds’ part. Of course, this will depend on the rates offered and the fees charged. Essentially, a split loan offers a way for you to ‘hedge your bets’ between interest rates rising or falling in future. 

Let’s say you took out a split home loan with the following:

  • A loan amount of $400,000 
  • A variable interest rate of 3.50% p.a. 
  • A fixed component of 3.00% p.a. 
  • A fixed period of five years
  • A 50:50 split 
  • P&I monthly repayments
  • A 30-year loan term  

In this case, your fixed repayments per month would be $843.20, while the variable repayments would be $898 per month, bringing your total monthly repayments to $1,741 during this five year period (and $1,788 thereafter). However, if your loan was entirely variable at 3.50%, those monthly repayments would be $1,796 per month. 

Over the five year period, your total P&I repayments would be:

  • Split loan: $104,460
  • Variable loan: $107,760 

So in this instance, your split loan repayments would be lower during the fixed period. Now, if there was a rate increase after one year (let’s say 25 basis points), then having half of your loan locked in a fixed rate would create a further discrepancy between potential split loan repayments and variable loan repayments. Using our example above, we can see that the variable component repayments rise after the interest rate increases from 3.50% p.a. to 3.75% p.a. 

  • Split loan: $1,769 monthly repayments during the first year and $1,797 during the next four years, total P&I repayment over five years = $107,664  
  • Variable loan: $1,852 monthly repayments: total P&I repayment over five years = $111,120

In the case of rising interest rates, you could save even more money by fixing a greater portion of your loan. But remember that lenders have teams of economists and loan specialists to basically ensure they come out on top.

If lenders are repeatedly dropping fixed interest rates, it’s unlikely that rates will rise, so it can be a dangerous game to fix too much of your loan. Sometimes keeping most of your loan to a variable rate can be the safer option. 

What happens when your split loan period ends? 

A misconception with split home loans that once the fixed period finishes, the entire home loan will revert to the interest rate on the variable component. For example, on a split loan with a fixed rate of 3.00% p.a. and a variable rate of 3.20%, one might think the fixed rate of 3.00% p.a. would revert to 3.20% p.a. at the end of the fixed period. But this doesn’t typically happen. 

The fixed-loan component may actually revert to a different ‘rollover rate’ specified in the terms and conditions of your split loan. This rate might be higher than the current variable rate of your split loan, and confusingly, this can actually mean you end up with two separate variable home loan interest rates for the remainder of the loan term (or until you choose to refinance the entire loan to a single rate).’s two cents 

Split home loans are just one of many home loan options available to customers. If you decide to go down the split home loan route, make sure you’ve compared a number of home loans based on their rates, fees and extra features.

You don’t want to sign up to a dud home loan just because it promises ‘flexible repayments’ due to its split facility. It’s entirely possible there are better fixed or variable rate home loans out there if you look hard enough. 

Also, keep in mind some of the possible traps of fixed rates. Just because only part of the loan is fixed under a split rate arrangement, doesn’t mean you’re safe from these traps. It still leaves that part of your loan susceptible to them. These traps can include:

  • Revert rates: At the end of the fixed term, fixed rates often revert to variable rates that are significantly higher than some of the lower variable rates on the market. 
  • Break fees: Should you need to end the fixed-rate contract early (e.g. you want to refinance to a lower rate, or you’ve sold your house) you’ll be liable for a break fee, which can cost thousands.
  • Falling rates: Banks set fixed rates based on their expert forecasts of where they think interest rates are headed.
