Do you know refinancing can change your loan term?

Refinancing gives you the option to adjust how long you'll be repaying your mortgage.

Most people refinance to access a lower interest rate, but the loan term - how many years you're paying the thing off - is just as important. You can shorten it to clear the debt faster and pay less interest overall, or extend it to drop your monthly repayments and improve cashflow. Both have their place depending on your current situation and what you're trying to achieve.

Why your loan term matters when you refinance

Your loan term controls two things: how much you pay each month and how much interest you pay over the life of the loan. A shorter term means higher repayments but less interest paid. A longer term reduces your monthly commitment but increases the total cost. When you refinance your home loan, you're not locked into the remaining term from your existing mortgage. You can set a new one that fits your current income, expenses, and goals.

Consider someone working rotating shifts who refinanced after a promotion. They had 22 years remaining on their loan but chose to restart at 30 years. The lower monthly repayment gave them breathing room during quieter months and meant they could still make extra payments when overtime was available without feeling stretched on base pay. The flexibility mattered more than the total interest cost because their income varies week to week.

Shortening your loan term to save on interest

If your income has improved or your expenses have dropped, refinancing to a shorter term can cut years off your mortgage and save a significant amount in interest. You'll pay more each month, but the loan is cleared faster and costs less overall. Most lenders will let you refinance to any term between 5 and 30 years, depending on your age and borrowing capacity.

In our experience, people who've paid down a chunk of their mortgage and are earning more than when they first borrowed often shorten the term without much strain on their budget. The monthly increase isn't always as steep as you'd expect, especially if you're also accessing a lower interest rate at the same time.

Extending your loan term to reduce monthly repayments

Extending your loan term when you refinance drops your monthly repayment, which can make a real difference if your roster has changed, you've taken on other debt, or you're managing a period of lower income. This approach increases the total interest you'll pay, but it also gives you room to breathe and the option to make extra repayments when you can.

This strategy works well for people coming off a fixed rate period who are facing a jump in repayments. Extending the term softens the increase while you adjust to the new rate. You're not committed to slower repayment - you can always pay more when your circumstances allow. The key is that your minimum repayment is manageable on a lean month.

How refinancing compares to just making extra repayments

You don't always need to refinance to change how fast you repay your loan. If your current mortgage allows extra repayments without penalties, you can achieve similar results by increasing your regular payment or making lump sum contributions. The difference is that refinancing locks in a new term and often comes with a lower rate, while extra repayments on your existing loan require discipline and don't reduce your minimum monthly commitment.

Refinancing makes sense when you want to formalise the change - either to force yourself into higher repayments with a shorter term, or to lock in lower minimum repayments with a longer term. If you're also switching lenders to reduce your interest rate or access different features, adjusting the loan term at the same time costs you nothing extra. A home loan health check can show you whether refinancing or sticking with your current loan and adjusting repayments makes more sense for your situation.

What lenders look at when you change your loan term

Lenders assess your refinance application based on your current income, expenses, and the loan amount you're requesting. If you're shortening your term, they'll check that you can afford the higher repayment. If you're extending it, they'll still assess your ability to service the loan at the new term, but the hurdle is usually lower because the repayment is smaller.

Your age also plays a role. Most lenders want the loan term to finish before you turn 70 or 75, so if you're refinancing later in your career, you may have less flexibility to extend. On the other hand, shortening your term is rarely an issue as long as you can prove you can afford the repayment. The refinance application process is similar regardless of the term you choose, but it's worth discussing your options before you commit to a specific structure.

Matching your loan term to your actual plan

The loan term you choose should reflect what you're actually trying to do with your mortgage, not just what sounds sensible in theory. If you're planning to sell in a few years, a 30-year term with the option to make extra repayments gives you flexibility without locking you into higher monthly commitments. If you're staying put and want the mortgage cleared before you retire, a shorter term keeps you accountable.

We regularly see people refinance with a longer term purely for cashflow reasons, then set up automatic extra repayments so they're still paying it off at the pace they want. That approach gives them a safety net if income drops or expenses spike, without committing them to the extended timeline. The structure you choose now doesn't have to be the structure you stick with - you can always refinance again if your situation changes.
