Beginner's Guide to Refinancing Payment Frequency Options

Refinancing Lets You Change How Often You Pay

When you refinance your home loan, you can adjust how often you make repayments, whether that's weekly, fortnightly, or monthly. Most lenders offer all three options, and the choice affects both your cashflow and the total interest you pay over the life of the loan.

For ADF members posted to Blackwood Forest, this decision often ties directly to how Defence pays you. Defence salary comes in fortnightly, so matching your repayment schedule to that income pattern can reduce the risk of missed payments and help you stay ahead on interest without needing to manage multiple transactions each month.

Why Payment Frequency Affects Interest

Switching from monthly to fortnightly repayments reduces the interest you pay because you make 26 repayments each year instead of 12. Each fortnightly payment is half your monthly amount, but because there are more than two fortnights in most months, you end up making the equivalent of 13 monthly payments annually instead of 12.

This shortens the time it takes to pay off the loan and cuts down on the total interest charged. The effect compounds over time, so the earlier you make the switch during a refinance, the more pronounced the benefit.

Fortnightly Repayments Aligned to Defence Pay Cycles

Defence salaries are paid fortnightly, and setting your loan repayments to match that schedule means every payday includes your mortgage payment. You're not waiting until the end of the month or managing leftover funds.

Consider an ADF member posted to the Army School of Signals at nearby Latchford Barracks who refinances a loan with a remaining balance at the suburb's current median. Switching from monthly to fortnightly repayments means each pay cycle includes the repayment, reducing the need to hold funds in a transaction account until the monthly due date. It also means interest is calculated on a lower outstanding balance more frequently, which adds up over the loan term.

Weekly Repayments for Tighter Cashflow Control

Weekly repayments work in a similar way to fortnightly, but with 52 payments each year. Each weekly payment is a quarter of your monthly amount, which means you make slightly more than 12 monthly payments annually.

This option suits members who prefer tighter control over their budget or who receive additional allowances that are paid weekly. Weekly repayments also reduce the average daily loan balance more quickly than fortnightly or monthly schedules, which lowers the total interest charged.

In our experience, members who are managing multiple debts or saving for a deposit on an investment property find weekly payments helpful because they can see progress more frequently and adjust spending week to week rather than trying to hold funds over a longer period.

Monthly Repayments When Offset Accounts Are in Play

Monthly repayments still have a place, particularly when your loan includes an offset account. If you're holding a high balance in offset throughout the month, the benefit of more frequent repayments is reduced because the offset is already lowering the interest charged on your loan balance.

Some ADF members who receive allowances in lump sums or who are saving for a posting-related move prefer to keep funds in offset and make a single monthly repayment. This approach works when cashflow is predictable and the offset balance stays consistently high.

If you're refinancing and considering whether to add an offset account or adjust your payment frequency, a loan health check can help you compare the two strategies and work out which one delivers the most value based on your current financial position.

Changing Payment Frequency During the Refinance Process

You nominate your payment frequency when you submit your refinance application. Most lenders will ask for this detail upfront, and it's locked in once the loan settles unless you request a change later.

If you're currently on a fixed rate that's expiring, refinancing gives you the opportunity to reassess your repayment structure at the same time as you move to a new rate. You're not limited to the payment frequency you had on your previous loan.

Some lenders also allow you to make extra repayments on top of your scheduled frequency, which can be useful if you receive an annual bonus or posting allowance and want to put it toward your loan without formally changing your repayment schedule.

What Happens If You Need to Switch Back

Most lenders let you change your payment frequency after your loan has settled, though some may require you to submit a request in writing or through their online portal. There's usually no fee for making this change.

If your posting changes or your cashflow circumstances shift, you can move from fortnightly to monthly or vice versa without needing to refinance again. The loan terms don't change, just the timing of the repayments.

This flexibility is worth confirming before you settle on a new lender during the refinance process, particularly if you expect your circumstances to change in the next year or two due to deployment or a new posting.

Matching Repayment Frequency to Deployment and Allowances

Deployment allowances and field pay are often paid separately from your base salary, and they can be irregular depending on your role and posting. If you're receiving these payments, fortnightly or weekly repayments let you direct the additional income toward your loan without needing to hold it until a monthly repayment is due.

Members posted to Blackwood Forest who are attached to units with frequent field exercises or short-term deployments often find that more frequent repayments align with how their total income flows in, rather than just their base salary. This reduces the risk of overspending between repayments and keeps the loan balance moving down consistently.

If you're refinancing and want to work out how to structure your repayments around deployment income or allowances, call one of our team or book an appointment at a time that works for you.
