Everything to Know About Variable Loans and Offset Accounts

A variable rate loan paired with an offset account lets your everyday savings reduce the interest you pay, while your cash stays within reach.

That is the whole idea. If you are weighing up a home loan in Point Cook, you can take a slow breath. The decision gets lighter once you see how the two parts fit together.

How Does a Variable Rate Home Loan Work?

A variable rate home loan has an interest rate that your lender can change over time. Your repayments can move up or down with it.

Lenders set variable rates for their own reasons, and the Reserve Bank's cash rate is one influence. That means your repayment is not locked in the way it is on a fixed rate. In return, variable loans often allow extra repayments and may include home loan features that fixed loans restrict. Features differ between lenders, so check the details of any loan you are considering.

Most owner occupied home loan borrowers choose principal and interest repayments. Each repayment covers the interest charged and also reduces the amount you owe. You can see how different amounts change your repayments with our mortgage repayment calculator.

How an Offset Account Works Day to Day

An offset account is a transaction account linked to your home loan. The balance in it is subtracted from your loan balance when the lender works out your daily interest.

Your pay can go in, your bills can come out, and the money is still yours to spend. With a full linked offset, every dollar sitting there reduces the balance that interest is charged on. Some accounts only offset part of the balance, so ask the lender which type you would get.

An offset account does not lower your required repayment. What changes is how much of each repayment goes to interest and how much goes to the loan itself.

A Worked Example: $40,000 in an Offset Account

A $40,000 offset balance on a $600,000 loan reduces the interest charged by roughly $2,700 a year at the illustrative rate used here. This is an example only, not a forecast.

Consider a Point Cook couple with an owner occupied home loan of $600,000 over 30 years. They use an illustrative variable rate of 6.75% p.a. with principal and interest repayments. Their repayment comes to about $3,892 a month.

They keep $40,000 in a linked offset account, made up of their emergency savings and a few months of upcoming bills. Interest is now charged as if they owed $560,000. At 6.75% p.a., that is about $3,150 of interest in a month instead of $3,375. The difference is about $225 a month, or about $2,700 over a year, as long as the balance stays there.

Their repayment stays at $3,892, so the extra $225 goes towards the loan balance rather than interest. They did not lock their savings away. If the hot water system fails, they can pay for it from the offset account. The outcome is that their savings keep working for them, and they keep access to the money. The saving only lasts while the balance stays in the account, and it shrinks if they draw it down.

What Are the Trade-Offs of Variable Loans and Offset Accounts?

The main trade-offs are that your repayments can rise, and that loans with an offset account can cost more through a higher rate or an annual package fee.

A variable rate can increase, which can put pressure on a household budget. It helps to ask what repayment you could comfortably carry if the rate went up, and to plan with that figure in mind.

Offset accounts also suit people who actually hold a cash balance. If your savings are small, a fee or a higher rate on the loan could cost more than the interest you save. Before choosing, compare rates and fees across a few lenders, with and without the offset feature. Our team can do that comparison with you across lenders, and you can read more about home loan options on our site.

There is also a behaviour trade-off. Money in an offset account is easy to spend because it sits in a transaction account. Some people feel calmer keeping a separate savings account for goals they do not want to touch.

Splitting Your Loan to Balance Certainty and Flexibility

A split loan divides your borrowing into a fixed rate portion and a variable rate portion, so you get some repayment certainty and some flexibility.

For example, a borrower might fix half the loan so that part of the repayment stays steady, and keep the other half variable with an offset account attached. The fixed portion gives you a known repayment for the fixed term. The variable portion keeps your extra repayments and offset balance working.

The cost of this approach is that the offset account usually only reduces interest on the variable portion. Fixed portions can also carry break costs if you repay or refinance early, and lenders set their own rules on this. If your fixed term is ending soon, our page on fixed rate expiry explains your choices.

Reviewing Your Loan When Your Life Changes

If you already have a loan, you can ask your lender or broker to review the rate and features at any time. A review can show whether a lower rate or an offset account would suit you now.

Many borrowers review their loans after a new job, a growing family or a renovation. If your rate feels high, you can look at refinancing to reduce your rate as one option. Refinancing may involve fees and a new application, so it is worth weighing the cost first.
