A variable rate loan with an offset account lets a first home buyer reduce interest by keeping savings linked to the loan, while keeping access to that cash. The trade-off is that your repayments can change when your lender changes the rate, and offset features can come with a higher rate or an annual fee, depending on the lender.
This article is for first home buyers in South Morang who are comparing loan structures before they apply. It explains how each feature works, and what to check before you choose.
How Does a Variable Rate Home Loan Work?
A variable interest rate moves up or down at your lender's discretion, usually (but not always) following changes in the cash rate set by the Reserve Bank. When the rate falls, your required repayment can fall. When it rises, your repayment goes up.
As an illustration only, a $600,000 loan at an example rate of 6.75% p.a. over 30 years has a principal and interest repayment of about $3,891 a month. If the rate rose by one percentage point to 7.75%, the same loan would need about $4,298 a month. That is a difference of roughly $407 a month, so your budget needs room for movement.
Variable loans often allow extra repayments without penalty, which a fixed interest rate loan may limit. A fixed rate gives certainty for a set period, but break costs can apply if you leave early. If you are weighing the two, our home loans page outlines the main structures, and the borrowing capacity page shows how lenders assess what you can borrow.
What Is an Offset Account and How Does It Reduce Interest?
An offset account is a transaction account linked to your home loan, and its balance is subtracted from your loan balance when interest is calculated. You pay interest only on the difference.
Consider a first home buyer with a $500,000 loan at the illustrative 6.75% p.a. who keeps $20,000 in the offset account. Interest is charged as if the loan were $480,000. Over one year, that is about $1,350 less interest than on the full balance ($20,000 x 6.75%). The money stays accessible for bills or emergencies.
The savings only apply while the money sits in the account. If the balance drops, so does the benefit. Offset accounts also tend to be offered on packaged loans, which may carry an annual fee or a higher rate than a basic loan. Whether the offset pays off depends on how much you keep in it. A small balance may not cover the extra cost.
Offset Account or Redraw: Which Suits Your Situation?
An offset account keeps your savings separate and linked to the loan, while redraw lets you withdraw extra repayments you have already made into the loan. Both reduce interest, but they differ in access and control.
With redraw, the money is part of the loan. Some lenders limit how much or how often you can withdraw, and some may need to approve the request. Offset funds work like an everyday account, so access is usually immediate. Redraw is often included in a loan at no extra cost, which suits buyers who want to pay down the loan and rarely need the cash.

Variable Rate and Offset Example for a South Morang First Home Buyer
For a South Morang buyer, a variable loan with an offset account suits someone who expects to hold a cash buffer and wants flexibility to make extra repayments. A buyer who needs fixed repayments for budgeting may prefer a fixed or split structure instead.
As an example, consider a couple buying their first home in South Morang with a $520,000 loan. They compare a basic variable loan at the illustrative 6.75% p.a. with a packaged variable loan that has an offset account and an annual fee. They expect to hold about $25,000 in everyday savings. At 6.75% p.a., that balance offsets about $1,688 of interest a year ($25,000 x 6.75%). The package fee is $395 a year, so the net benefit is about $1,293 a year, assuming the rate on both loans is the same. In practice, packaged loans can carry a different rate, so they check this with their broker.
Their outcome: the packaged loan makes sense while they keep that balance. If their savings fell to $5,000, the interest saved would be about $338 a year, which would not cover the fee. They choose the offset loan and review it each year. Our Mortgage Broker in South Morang page has details on how we work with local buyers.
How Do Grants and Stamp Duty Concessions Affect Your Loan Choice?
In Victoria, a first home buyer pays no land transfer duty on a dutiable value up to $600,000, with a concession between $600,000 and $750,000, and standard rates above $750,000. The buyer must live in the home as their principal place of residence for at least 12 months, starting within 12 months of settlement.
The Victorian first home owner grant is $10,000 and applies only to new homes with a dutiable value up to $750,000. It does not apply to established homes. Because the grant is not available for established homes, your deposit plan may differ depending on what you buy. You can estimate your costs with our stamp duty calculator.
The federal 5% Deposit Scheme lets eligible first home buyers buy with a 5% deposit without paying lenders mortgage insurance. It is accessed only through a participating lender. Loan features such as offset accounts vary by lender, so confirm with the participating lender whether an offset account is available before you commit. Price caps apply, and the cap depends on the suburb and postcode in Housing Australia's postcode search tool. If your deposit is smaller, the lender may charge more or require LMI outside the scheme.
Checking Your Structure Before You Apply
Before a formal application, a pre-approval helps you see what a lender is willing to offer, and lets you compare how an offset account, redraw and variable rate suit your budget. Pre-approval is not a final commitment, and lenders can reassess when you apply.
Once you own a home, the loan health check helps you review whether the rate and features still suit you.
Frequently Asked Questions
How does an offset account work on a variable rate loan?
An offset account is a linked transaction account whose balance is subtracted from your loan balance when interest is calculated. You pay interest only on the remaining amount, while still having access to your cash.
What is the difference between offset and redraw?
An offset account keeps your savings separate from the loan, while redraw lets you withdraw extra repayments you have already made. Redraw access can be limited by the lender, whereas offset funds are usually available immediately.
Are offset accounts worth the extra cost?
It depends on the balance you keep in the account and the fee or rate difference. A small balance may save less interest than the annual fee costs.
Do first home buyers in Victoria pay stamp duty?
No land transfer duty is payable for a first home buyer on a dutiable value up to $600,000, with a concession up to $750,000. The buyer must meet the residence requirement, so check your situation with a professional.
