The easiest way to pick a variable rate loan term

A variable rate loan gives you flexibility with repayments and features, but the loan term you choose sets the pace for how quickly you pay down the balance.

Variable Rate Loan Terms: How They Work

A variable rate loan term is the number of years you take to repay the loan. Most lenders offer terms from 1 to 30 years. A shorter term means higher monthly repayments but less interest paid over the life of the loan. A longer term reduces monthly repayments but increases the total interest cost.

Consider a Navy member posted to HMAS Kuttabul buying with a 10% deposit under the Australian Government 5% Deposit Scheme. At current variable rates, a $400,000 loan over 25 years might require monthly repayments around $2,400. The same loan over 30 years drops monthly repayments to roughly $2,200, but the total interest paid rises by tens of thousands of dollars.

The term you choose affects how much room you have in your budget each month and how much flexibility you have to make extra repayments when circumstances allow.

Matching Loan Terms to Deployment Cycles

Navy members move between sea postings, shore postings, and periods of training or leave. Each phase affects income differently. A shorter loan term might suit a member on sea posting with higher allowances and fewer living costs, while a longer term offers breathing room during shore postings or when household income drops.

You can structure a variable rate loan with a longer term to keep repayments manageable, then make extra repayments when income increases. Most variable rate loans let you pay more without penalty, and many include an offset account or redraw facility so you can access those extra funds if needed.

If you are buying under the 5% Deposit Scheme, a longer loan term can reduce the monthly repayment burden while you build equity in the first few years. No lenders mortgage insurance applies under the scheme, so the deposit size does not add upfront cost beyond stamp duty and settlement fees.

How Offset Accounts Change the Calculation

An offset account is a transaction account linked to your home loan. The balance in the offset account reduces the loan balance on which interest is calculated. If you have a $400,000 loan and $20,000 in an offset account, you pay interest on $380,000.

For Navy members with irregular income or allowances that fluctuate, an offset account paired with a longer loan term gives you the option to park extra funds and reduce interest without locking them into the loan. You still have access to the money if circumstances change.

Not all variable rate loans include an offset account. Some lenders charge a higher interest rate or an annual fee for the feature. If you plan to keep a buffer in savings, the offset account usually pays for itself. If you spend most of your income each month, a redraw facility may be sufficient.

Redraw vs Offset: What Fits Your Posting Pattern

A redraw facility lets you withdraw extra repayments you have made above the minimum. Most variable rate loans include redraw at no extra cost. An offset account keeps your savings separate from the loan but delivers the same interest saving.

The difference matters when you are posted interstate or deployed for extended periods. An offset account gives you immediate access to funds through your transaction account. Redraw may require a few days to process, and some lenders limit how often you can redraw or charge a fee per transaction.

If you are likely to move between postings or face unexpected costs related to relocation, an offset account paired with a 30-year loan term gives you maximum flexibility. If your income is stable and you plan to stay in one location, a redraw facility with a shorter term may suit better.

First Home Buyer Stamp Duty Concessions and Loan Structure

Most states and territories offer stamp duty concessions to first home buyers. In New South Wales, full transfer duty exemption applies on properties up to $800,000, with a sliding concession up to $1,000,000. In Victoria, full exemption applies up to $600,000, with a concession up to $750,000.

These concessions reduce the upfront cost of buying, which means you may not need to borrow as much or stretch the loan term as far to keep repayments affordable. A Navy member buying in Western Sydney with a property value of $750,000 and a 10% deposit would save roughly $30,000 in stamp duty under the New South Wales concession. That saving can go toward genuine savings, settlement costs, or a larger deposit, all of which reduce the loan amount and give you more flexibility with the loan term.

If you are buying in Queensland, the stamp duty concession applies up to $700,000 for established homes, with a partial concession up to $800,000. The First Home Owner Grant of $15,000 applies to new homes valued under $750,000 for contracts signed from 1 July 2026. These concessions do not change the loan term directly, but they reduce the amount you need to borrow, which gives you the option to choose a shorter term without increasing monthly repayments.

Refinancing to Shorten the Term Later

You are not locked into the loan term you choose at settlement. If your income increases or you receive a posting allowance that gives you more room in the budget, you can refinance to a shorter term or simply increase your repayments without changing the loan structure.

Most variable rate loans let you increase repayments at any time. If you want to formalise the change and reduce the loan term on paper, refinancing lets you do that. Home loan refinancing also gives you the opportunity to review your interest rate, loan features, and lender at the same time.

If you refinance after a few years and your loan balance has dropped, you may qualify for a lower interest rate or better loan features. That can offset the cost of refinancing and give you a lower monthly repayment even with a shorter term.

Choosing the Right Term Without Overstretching

The loan term that fits your circumstances now may not suit you in three years. A 30-year term gives you flexibility to adjust repayments as your income changes. A 25-year term reduces total interest without pushing monthly repayments to a point where you have no room for extra costs.

If you are posted to Garden Island, HMAS Albatross, or HMAS Cerberus, your housing costs and commute will differ depending on whether you live on base, nearby, or further out. A longer loan term keeps monthly repayments low enough that you can afford to live closer to work if needed, while still having the option to pay extra when you are on deployment or receiving higher allowances.
