A home loan can feel like a long commitment, but the standard loan term is not always the only path. With a suitable loan structure and a repayment plan that fits your budget, you may be able to reduce mortgage interest and pay off your home sooner.
There is no single strategy that suits every household. The right approach depends on your interest rate, loan features, cash flow and need for access to savings. Here are some practical home loan payoff strategies to consider, and the details to check before making a change.
Start with the basics: what helps reduce mortgage interest?
Home loans usually charge interest on the outstanding balance. Paying down that balance sooner, or keeping savings in an eligible offset account, can reduce the amount of debt on which interest is calculated.
As a result, more of your regular repayment may go toward paying off the principal: the amount you borrowed, excluding interest and fees. The earlier you reduce the balance, the longer you may benefit from paying less interest, provided your loan terms and repayment schedule support it.
Before you make changes, check:
- Your current interest rate and whether it is fixed or variable.
- Your remaining loan term and repayment amount.
- Whether your repayments are principal and interest or interest-only.
- Any limits, fees or conditions on extra repayments, offset or redraw.
- How much cash you need to keep accessible for emergencies.
1. Use an offset account if the numbers work
An offset account is a transaction account linked to an eligible home loan. The money in it is generally taken into account when the lender calculates interest.
For example, if you have a $500,000 loan and $20,000 in a fully linked offset account, interest may be calculated on about $480,000. You still owe the loan balance, but you may pay less interest while the savings remain in the offset. The exact calculation depends on your lender and account terms.
Potential mortgage offset account benefits
- Your savings remain accessible for eligible spending.
- You may reduce the interest charged without making a permanent extra repayment.
- Your regular repayment can then pay down principal faster, depending on the loan’s structure.
The key is to compare the savings with the cost. Offset accounts may come with account or package fees, or be attached to a loan with a higher interest rate than a similar loan without an offset. As a simple illustration, an average offset balance of $20,000 against a hypothetical 6% interest rate could represent about $1,200 in annual interest avoided before fees and other differences. This is an estimate, not a lender quote; actual savings depend on daily balances, rates and loan conditions.
Moneysmart’s guide to mortgage offset accounts explains how they work and what costs to compare. If you already have an offset, check your statements or online banking to confirm it is linked and operating as expected. In July 2026, ASIC published Report 837 on banks’ communication about offset accounts, highlighting why it is worth checking what happens to an offset when you refinance or change loan products.
2. Make extra repayments you can sustain
Extra repayments reduce your loan balance, which can lower interest over time. Even a manageable regular amount may help, especially when you make it consistently and your lender applies it to the loan as expected.
Possible ways to build extra repayments into your plan include:
- Adding a set amount to each regular repayment.
- Putting some of a bonus or tax refund toward the loan.
- Increasing your payment when your income rises, if your budget allows.
- Keeping repayments at their current level if your minimum required repayment falls, rather than automatically reducing what you pay.
Before you transfer money, check your loan rules. Many variable-rate loans allow extra repayments, but fixed-rate loans can have annual limits or other restrictions during the fixed period. Exceeding a limit may lead to fees or other consequences under your contract.
A redraw facility may let you access some extra repayments later, but access can depend on lender rules, fees and processing times. It is not always as flexible as money held in a transaction account. If you need a reliable emergency reserve, consider that before committing all your spare cash to the loan.
What about fortnightly repayments?
Paying half your monthly repayment every two weeks can result in 26 half-payments across a year. The equivalent of 13 monthly payments. That may help you pay down the balance faster, but check how your lender schedules and credits repayments. Make sure the higher annual amount fits your budget and does not create cash-flow pressure.
3. Review your loan term and structure
A shorter contractual loan term usually means higher required repayments. This can help you pay off the loan sooner, but it also leaves less room in your monthly budget. A longer term may mean lower minimum repayments, but paying only the minimum over a longer period can increase total interest.
You may also be able to make higher repayments voluntarily on a loan with a longer term. This can provide more flexibility if your circumstances change, but only if your loan permits the extra payments and you follow through with a sustainable plan.
When comparing structures, look beyond the headline rate. Consider:
- The required repayment and total cost over the period you expect to keep the loan.
- Whether an offset account or redraw facility is included.
- Fees, rate discounts and any package conditions.
- Flexibility to make extra repayments or access funds.
- What the rate and repayment may become when a fixed period ends.
A lower interest rate can be valuable, but switching loans may involve discharge, application or valuation costs, and you could lose features you rely on. ASIC’s refinancing guidance recommends considering the costs and benefits of a switch rather than focusing only on the advertised rate.
Fixed versus variable: check the conditions first
Variable-rate loans often offer more flexibility for extra repayments, offset accounts or redraw, but rates and repayments can change. Fixed-rate loans offer more certainty during the fixed period, but may limit extra repayments or access to offset features. Restrictions vary between lenders and products.
Before making a lump-sum repayment, refinancing or paying off a fixed loan early, ask your lender about repayment caps and any potential break costs. If your fixed period is ending, review your options before the loan reverts to another rate. You can read more about the trade-offs in Moneysmart’s guide to fixed and variable home loan rates.
A practical plan to get started
You do not need to overhaul your finances all at once. A straightforward review can help you identify which changes are realistic:
- Check your loan details. Confirm your balance, rate, repayment type and remaining term.
- Protect a cash buffer. Keep enough accessible money for emergencies and near-term expenses.
- Compare features and costs. Work out whether an offset or redraw feature is worth its fees or any rate difference for your circumstances.
- Choose a manageable extra amount. Set a regular repayment you can maintain, rather than relying on an ambitious target that strains your budget.
- Check the result periodically. Review your statements and confirm any offset or extra payments are being handled as expected.
- Get guidance before switching. Compare the full costs, loan features and repayment implications, not just the interest rate.
The right strategy is the one you can maintain
Offset accounts, extra repayments and a suitable loan term can all help you pay off a mortgage faster, but their value depends on your circumstances and the loan’s rules. In reality, a strategy that preserves a sensible cash buffer and fits your household budget may be more effective over time than one that looks impressive on paper but is difficult to sustain.
