Want to save money by switching your home loan? How about paying off your mortgage sooner, or making use of your equity? If you haven't thought about your mortgage since you bought your first home, you may be surprised by the potential time and money savings by switching. 

Calculate if refinancing may be worth it for you, and compare a wide range of home loan options.

How to use a refinance home loan calculator

The best way to use a refinance mortgage calculator is to first work out exactly what you’re looking for in your next home loan, then apply the relevant calculations.

Some examples of what you might be looking for in a new home loan include:

  1. Reducing your repayments. A refinance calculator can help you switch and save, by working out the lowest interest rates you may be able to afford, and how much you may save compared to your current mortgage rate.
  2. Paying off your loan faster. Whether you’re five or fifteen years into paying off your home loan, refinancing to a lower interest rate may allow you to shorten your loan term. If you keep making the same home loan repayments as you are now, but switch to a lower rate, you may be able to pay off the loan much sooner.
  3. Choosing a different loan type. Maybe you are on a variable rate home loan and now want the stability of locking in a fixed rate home loan, so your repayments are no longer subject to market conditions, or vice versa?
  4. Getting cash out of your home loan. Perhaps you’re looking to consolidate some debt or renovate your home? Refinancing your home loan can let you enjoy flexible features, such as a redraw facility, or you could refinance and borrow a little more to have some extra cash at your disposal.

Once you know what you want from your new home loan, you can select the correct option from above the calculator.

Next, all you’ll need to do is:

  • Enter your loan balance
  • Enter your current monthly repayments
  • Enter your current interest rate

Then, depending on what refinancing journey you are on, you’ll need to:

  • Enter the amount of cash out you want; or
  • Enter a number of years to see how much you may save with different homeloans over time by switching.

Your calculations, and potential new home loans will then automatically load in the comparison table.

  • Keep in mind that a refinance home loan calculator does not take every aspect of your personal situation into account, such as your credit score or employment status, and is not a substitute for professional financial advice. Consider contacting your mortgage broker for advice specific to your personal circumstances.

Why should you use a refinance home loan calculator?

The refinance calculator is a tool to help you calculate how much you may save in time and repayments when switching your home loan, as well as how much you seek to gain through new loan features.

Whether your home loan costs you more per month than you’d prefer to pay, or you'd like to be out of debt sooner, or you want to put the equity in your home to use, you may want to calculate whether refinancing your mortgage will help you achieve these goals.

RateCity's refinance calculator can help you quickly and easily compare the costs and benefits of refinancing your mortgage across the home loan market.

A bank’s refinancing home loan calculator may show you potential savings, but will generally only direct you to refinance with that bank. Further, bank calculators don’t always let you adjust the figures in your calculation, like the interest rates and mortgage terms. This may prevent you from being able to see how each factor will impact potential new home loan options.

For example, a home loan package also offering credit cards may sound like a competitive option, but will also typically incur higher costs and fees from the lender. A refinancing calculator can help to show you the more realistic cost of switching.

What should I look out for when refinancing?

Before you refinance your mortgage, it’s important to confirm that you’ll be getting a better deal than your current loan. A few small details could make a big difference to the cost and benefits of your home loan.

For example, when some borrowers refinance, they choose a longer home loan term than their current mortgage, so their monthly payments are even cheaper. However, the longer you take to pay back your loan amount, the more interest payments you’ll need to make. Even if your new home loan has a lower interest rate, you could still end up paying more in total interest charges over the life of the loan by switching to a longer home loan term.

To illustrate, if you’re 10 years away from paying off your mortgage, refinancing to a new home loan with a 30-year term could end up costing you more money in total, even if the interest rate is lower. It’s important to compare your options and consider contacting a finance professional before applying to refinance.

Pros and cons of refinancing your home loan

There are both advantages and disadvantages to refinancing your home loan that are worth weighing up before you make the switch.

Pros:

  • Switch and save. You could potentially save big on your repayments if you switch to a home loan with lower interest rates and/or lower fees.
  • Greater flexibility. You may find it easier to manage your loan if you switch to a new mortgage that is more flexible (e.g. adding an offset account, redraw facility, split interest and more).
  • Shave years off the loan. By switching to a lower rate loan, but keeping your monthly mortgage payment amounts the same, you may shave years off of your loan through reducing the principal faster, and therefore reducing the interest you may be charged.

Cons:

  • Forgetting about fees. If you don’t also factor potential fees and refinancing charges into your refinancing costs (such as new loan upfront fees), you run the risk of losing money you saved in lower interest charges. The potential savings may be exceeded by the fees accrued during the refinancing process.
  • Risk of less flexibility. You may find it harder to manage your mortgage if your new home loan is less flexible.
  • Paying LMI. You may need to pay lender’s mortgage insurance (LMI) if your home has fallen in value and your LVR has been pushed up above 80 per cent.

Frequently Asked Questions

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.

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.

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.
