Extra repayments work because every dollar you add goes straight to your loan balance, so less interest is charged from that point on. If you own a home in Mt Eliza and want to pay down your home loan sooner, the right method depends on your loan type and how much flexibility you want.
This article covers the main ways to pay extra, the trade-offs of each, and two worked examples. All figures use an illustrative rate of 6.75% p.a. Your own rate will depend on your lender and your loan.
How Do Extra Home Loan Repayments Actually Reduce Interest?
Interest is calculated on your outstanding balance, so a lower balance means less interest charged each period. Extra repayments reduce that balance faster than your scheduled repayments alone.
Consider a borrower with a $600,000 loan amount on a 30 year principal and interest loan at an illustrative 6.75% p.a. The scheduled repayment is about $3,892 a month. In the first month, interest is about $3,375, which leaves only about $517 going to the balance.
Now the borrower adds $300 a month. That extra amount goes entirely to principal, so about $817 reduces the balance in that first month instead of $517. Each later month starts from a lower balance, so the interest portion shrinks a little sooner. The trade-off is that $300 less is available each month for everyday costs or other goals, so the amount needs to suit your budget. A calculator is a sensible way to test different amounts when you are calculating home loan repayments.
Which Extra Repayment Method Suits Your Loan?
The three common methods are paying more than the minimum, using redraw, and using an offset account. Which one suits you depends on whether your loan has a variable rate or a fixed rate, and how much access to your money you want.
On a variable rate loan, extra repayments are usually accepted without penalty, though you should confirm this with your lender. Fixed rate loans often cap how much extra you can pay each year, and going over the cap may trigger a fee. That makes a fixed rate less flexible for this strategy.
Redraw lets you withdraw extra repayments you have made, but some lenders limit or condition access. An offset account keeps your savings in a separate transaction account linked to your loan. The balance is netted against your loan when interest is calculated, and your money stays available.
The cost of an offset account is that loans with this feature may carry a higher rate or an annual fee, depending on the lender. It is worth comparing the total cost, not only the headline rate. You can see the loan structures we work with on our home loans page.

Offset Account Example: What $30,000 Can Do
An offset account reduces the balance your interest is charged on, while keeping your cash accessible. The saving depends on how much you keep in the account and for how long.
Take the same $600,000 loan at the illustrative 6.75% p.a. A borrower keeps $30,000 in a linked offset account, which is a mix of savings and money set aside for upcoming bills. Interest is then calculated on $570,000. Monthly interest falls from about $3,375 to about $3,206, a difference of roughly $169 a month at that rate.
The borrower still has access to the $30,000 if an unexpected expense arises. If they withdraw it, the interest saving drops with the balance. The outcome is a lower interest charge without locking money away, as long as the account balance is kept steady. This only works while the loan is variable or the lender offers offset on the fixed portion, so check this before you commit.
Split Loan Structures: Fixed Certainty With Variable Flexibility
A split loan divides your loan amount into a fixed portion and a variable portion. You get repayment certainty on one part and the ability to pay extra on the other.
For instance, a borrower might fix half of the loan and leave half variable, then direct all extra repayments and the offset account to the variable half. The trade-off is that the fixed portion has less flexibility, and if rates fall the fixed part will not follow. If rates rise, the variable part will. Your lender will explain the break costs that may apply if you leave a fixed portion early.
If your current loan does not allow extra repayments or an offset account, refinancing may be worth reviewing. Switching has costs, such as discharge and application fees, so those should be weighed against the potential interest saving.
How Much Extra Should You Pay Without Straining Your Budget?
Pay an amount you can keep up comfortably after covering living costs, and keep an emergency buffer before directing spare cash into your loan. A smaller regular amount that you maintain often does more than a large amount you cannot sustain.
Some borrowers pay half of the monthly repayment every fortnight, which results in the equivalent of one extra monthly repayment each year. Others round repayments up to a set figure or put a tax refund or bonus on the loan as a lump sum. Each of these builds equity in your home over time, but money paid into a loan is not as easy to reach as savings, unless you use redraw or an offset account.
It is also worth thinking about your next move. If you plan to upgrade or change lenders, check whether your loan is portable and whether any redraw balance is accessible. If you are buying your first property, our first home buyers page explains how to set up a loan with extra repayments in mind.

Frequently Asked Questions
Do extra repayments reduce the interest on my home loan?
Yes. Extra repayments reduce your loan balance, and interest is charged on the balance that remains. The lower the balance, the less interest is charged going forward.
Can I make extra repayments on a fixed rate loan?
Often only up to a yearly cap, and going over it may trigger a fee. A variable rate loan is usually more flexible, so check your lender's terms.
What is the difference between redraw and an offset account?
Redraw lets you withdraw extra repayments you have already made, and access can be limited by some lenders. An offset account holds your savings in a linked account and reduces the balance interest is charged on, while keeping the money available.
Does an offset account have any downsides?
Loans with an offset account may carry a higher rate or an annual fee, depending on the lender. It is worth comparing the total cost against the interest you expect to save.
