Offset Accounts, Redraw Facilities and Loan Features: What Actually Saves You Money

19/4/2026

The interest rate gets all the attention. But the features attached to your home loan can save you tens of thousands of dollars over the life of the loan, or cost you just as much if you choose the wrong product. Here is what matters and what does not.

When most people compare home loans, they start and end with the interest rate. That is understandable. The rate is the single biggest variable in how much your loan costs. But two loans with identical rates can produce dramatically different outcomes over 25 or 30 years depending on the features they include.

An offset account, a redraw facility, the ability to make extra repayments without penalty, and the option to switch between repayment frequencies are all features that affect the true cost of your loan. Understanding how they work, and which ones matter for your situation, is the difference between a loan that works for you and one that works against you.

The 100% Offset Account

An offset account is a transaction account linked to your home loan. The balance in the offset account is deducted from your loan balance before interest is calculated.

If you have a $500,000 loan and $50,000 sitting in your offset account, you only pay interest on $450,000. The $50,000 in your offset still earns you a "return" equal to your home loan interest rate, because it is reducing the interest charged on your loan. And unlike savings account interest, this return is not taxable.

Why This Matters

At a rate of 6.5%, a $50,000 offset balance saves you approximately $3,250 per year in interest. Over 25 years, that $50,000 permanently sitting in your offset would save you roughly $81,000 in total interest and shorten your loan term by several years.

The key word is "permanently." An offset account only saves you money while the funds are in it. If you use the account for daily spending and the balance fluctuates between $5,000 and $50,000, your savings will be based on the average balance, not the peak.

100% vs. Partial Offset

Some lenders offer a "partial" offset, where only a portion of your account balance (sometimes 50% or 75%) is offset against the loan. This is a significantly less valuable feature. If you are choosing a loan with an offset account, make sure it is a full 100% offset.

Offset Account Fees

Some lenders charge a monthly or annual fee for an offset account, or only include it with their premium loan packages that carry a slightly higher rate. Whether the offset is worth the fee depends on how much money you expect to keep in the account. If you maintain a healthy balance, the interest savings will far outweigh the fee. If your balance is typically under $5,000, the fee may erode the benefit.

Redraw Facilities

A redraw facility allows you to access extra repayments you have made on your loan. If your minimum monthly repayment is $3,000 and you have been paying $3,500, the extra $500 per month accumulates in your loan as "available redraw."

The Difference Between Offset and Redraw

On the surface, offset accounts and redraw facilities seem to do the same thing: reduce the interest you pay. But there are important differences.

Access: Money in an offset account is your money in a transaction account. You can spend it, transfer it, and use it with a debit card, exactly like a normal bank account. Redraw requires a specific request to your lender, which may take hours or days to process, and some lenders impose minimum redraw amounts.

Control: With an offset account, you maintain full control of your cash at all times. With redraw, some lenders reserve the right to restrict access under certain circumstances (though this is rare with mainstream lenders).

Tax implications for investors: For investment properties, keeping funds in an offset account rather than making extra repayments via redraw preserves the full tax-deductibility of your loan interest. This is a critical distinction for anyone with an investment property loan.

Recommendation: If you have the choice, an offset account is almost always the more flexible and more useful feature. Redraw is better than nothing, but offset is the gold standard.

Extra Repayments

The ability to make additional repayments above your minimum without penalty is one of the most powerful features a home loan can offer. Extra repayments reduce your principal faster, which means you pay less interest over the life of the loan and shorten your loan term.

On a $500,000 loan at 6.5% over 30 years, an extra $200 per month saves you approximately $90,000 in interest and takes roughly five years off your loan.

Fixed Rate Limitations

If you are on a fixed rate, extra repayments are often capped. Many lenders allow $10,000 to $20,000 in extra repayments per year during a fixed rate period. Beyond that cap, you may face break fees. This is one of the key trade-offs of choosing a fixed rate: you get certainty on repayments, but you lose flexibility.

Variable rate loans typically allow unlimited extra repayments at no cost. This is one of the reasons many borrowers prefer variable, or use a split loan structure (part fixed, part variable) to get the best of both worlds.

Repayment Frequency: Monthly vs. Fortnightly

Switching from monthly to fortnightly repayments is one of the simplest ways to pay off your loan faster without increasing your per-repayment amount.

The maths is straightforward. Monthly repayments mean 12 payments per year. Fortnightly repayments (half the monthly amount, paid every two weeks) result in 26 fortnightly payments, which equals 13 monthly-equivalent payments per year. That one extra payment per year goes directly to reducing your principal.

On a $500,000 loan at 6.5% over 30 years, switching from monthly to fortnightly repayments saves approximately $65,000 in interest and cuts roughly four years off the loan term.

Loan Portability

Loan portability allows you to take your existing loan with you when you sell one property and buy another. Instead of discharging your current loan and taking out a new one (with new application fees, potentially new LMI, and the hassle of a full reassessment), you simply transfer the existing loan to the new property.

Not all loans offer portability, and not all lenders make the process straightforward. If you anticipate selling and buying within the next few years, portability is a feature worth prioritising.

Split Loans: Fixed and Variable

A split loan divides your mortgage into two portions: one at a fixed rate and one at a variable rate. This gives you partial certainty (the fixed portion) and partial flexibility (the variable portion, which you can use for extra repayments and an offset account).

The split can be any ratio you choose: 50/50, 70/30, 80/20, depending on your appetite for certainty vs. flexibility.

In the current rate environment, with the RBA cash rate at 4.10% and expert opinion divided on whether further increases are ahead, a split structure allows you to hedge your position rather than committing entirely to one view.

How to Choose the Right Features

The features that matter most depend on your financial behaviour and your goals.

If you are a disciplined saver who maintains a healthy cash balance, a 100% offset account is the single most valuable feature you can have. It effectively earns you a tax-free return equal to your home loan rate on every dollar you keep in the account.

If you want repayment certainty but do not want to sacrifice all flexibility, a split loan with an offset on the variable portion gives you both.

If you are focused on paying off your loan as fast as possible, unlimited extra repayments and fortnightly payment frequency will have the greatest impact.

If you are an investor, the offset account's tax advantages make it an essential feature, and the distinction between offset and redraw is not optional but critical to your tax position.

A broker who understands your goals can match you to a loan where the features align with how you actually manage your money, not just the loan with the lowest headline rate.
