Credit cards, car loans and buy now pay later usually cost more than any investment can reliably earn. Why they generally go first, where HELP fits, and when consolidation helps.

For most people, clearing high-rate consumer debt comes before debt recycling. A card charging around 20% is a certain cost, while an investment return is not, and many lenders count card limits against borrowing capacity even with nothing owing. HELP debt is different: it is indexed rather than charged interest and repaid through your tax return, so it rarely needs to go first. Consolidating into the home loan lowers the repayment but stretches short-term debt over decades.

Debt recycling turns non-deductible home loan debt into deductible investment debt over time. It does nothing for a credit card, car loan or personal loan, which stay non-deductible and usually carry a much higher rate than your mortgage.
That makes the order simple for most home owners: clear the expensive private debt first, then point surplus cash at the home loan and the investment split. Starting a leveraged strategy while carrying 20% debt adds risk on top of a cost you already know.
Cash flow is the other reason. Debt recycling relies on steady surplus income to pay the investment interest and push down the home loan. Card and personal loan repayments eat that surplus, and a strategy that only works when nothing goes wrong is the wrong one to start.
The exceptions are debts that are cheap, small or nearly gone, and HELP, which works differently.
Every dollar paid off a card saves that card's rate, with certainty and no tax to pay on the saving. To beat it, an investment would need to earn more than that rate after tax, every year, with no market falls.
| Use of $10,000 | Illustrative outcome | Certainty |
|---|---|---|
| Pay off a card at 20% | About $2,000 a year in interest avoided | Certain |
| Pay off a home loan at 6% | About $600 a year in interest avoided | Certain |
| Recycle into investments | Depends on returns, the loan rate and your tax rate | Uncertain |
The rates are assumptions for illustration. On a 30% marginal tax rate plus the 2% Medicare levy, a taxable investment would need roughly 29% a year before tax to match a 20% card. No sensible plan relies on that.
Many lenders assess the limit on each card, not the balance. A $15,000 limit you pay off every month is still treated as a commitment you could draw on, and it reduces how much you can borrow.
Take an illustrative couple with three cards totalling $30,000 in limits and $2,000 owing. A lender that assesses limits counts a monthly commitment against the full $30,000, not the $2,000. Cutting that to one card with a $5,000 limit can free up meaningful capacity for the investment split, with no change to income or spending.
Debt recycling needs an investment split approved against your income, so unused limits can shrink or block it. Reducing limits to what you use, and closing cards you do not need, often adds more borrowing capacity than people expect.
Buy now pay later accounts are increasingly treated as credit, and many lenders ask about them and look for them on bank statements. Close the ones you no longer use before you apply.
Not every consumer debt deserves the same urgency. A rough order for most people:
A loan with only a few months left may not be worth paying out early once break fees and the loss of a cash buffer are counted. A larger balance with years to run usually is.
Keep an emergency fund while you do this. Clearing every debt to zero with no cash behind you leaves the next car repair on a card.
Clearing consumer debt first is the default, not a rule. Starting debt recycling alongside a remaining debt can be reasonable when:
A simple illustration: a household with a $4,000 car loan balance and 10 months left, no cards, and $2,000 a month spare. The car loan will be gone soon either way, so waiting a year to start adds little. The same household with $18,000 across two cards would generally be better placed clearing the cards first.
What does not change is the separation. Consumer debt, home loan debt and investment borrowing each need their own account, so nothing private ends up in the investment split. Your financial adviser decides whether starting now fits your plan; we confirm the lending supports it.
HELP (formerly HECS) is not charged interest. The balance is indexed each 1 June at the lower of CPI or the Wage Price Index, which the ATO set at 2.8% in 2026 and 3.2% in 2025.
Two recent changes matter. The ATO applied a 20% reduction to all study and training loan debts that existed on 1 June 2025. From 1 July 2025, compulsory repayments are calculated only on income above the minimum threshold, $67,000 for 2025-26, rather than on your whole income.
Because indexation is usually well below a home loan rate, paying HELP off early rarely beats putting the same cash on the mortgage. Many lenders count compulsory HELP repayments as an expense, though, so a large balance can reduce borrowing capacity. Whether a voluntary repayment helps your application is worth checking with us before you make it.
We structure the lending, coordinate with your adviser and accountant, and tell you plainly when debt recycling is not the right fit.

| $20,000 of card debt | Monthly repayment | Total interest |
|---|---|---|
| Kept on a card at 20%, repaid over 3 years | About $743 | About $6,800 |
| Added to a home loan at 6%, repaid over 30 years | About $120 | About $23,200 |
| Added to a home loan at 6%, repaid over 3 years | About $608 | About $1,900 |
Rates are illustrative assumptions. The last row is the one that works: consolidate into a separate split and keep paying it at close to the old repayment. Consolidated debt is also non-deductible, so it adds to the balance debt recycling is trying to shrink.
Our debt consolidation home loan page explains how we set this up, including closing the old limits at settlement.
Include cards, BNPL, car and personal loans, and HELP, with rates, balances and limits.
Hold enough cash to cover a surprise bill without reaching for a card.
Pay the highest rate first, or consolidate into its own split with a short repayment plan.
Reduce or close cards and BNPL accounts before any loan application.
With consumer debt gone, the loan structure for debt recycling has room to work.
The debt consolidation calculator compares total interest under each option using your own numbers.
If you are unsure whether you are ready at all, our guide on when not to debt recycle covers the other signs to wait.
For most people, yes. A card charging around 20% is a certain cost that no investment reliably beats after tax, and the card limit reduces how much a lender will approve for the investment split. Clearing the card, then reducing or closing the limit, usually leaves you better placed to start debt recycling.
Not always, but many lenders assess the full limit even when the balance is zero. Reducing limits to what you actually use, and closing cards you do not need, can lift borrowing capacity. Many people keep one low-limit card for convenience and close the rest before applying for the investment split.
Usually not as a priority. HELP is indexed at the lower of CPI or wage growth rather than charged interest, and compulsory repayments are now based only on income above the threshold. Paying a home loan down generally saves more. Many lenders count HELP repayments as an expense, so check the effect on borrowing capacity with your broker first.
No. Deductibility follows what the borrowed money was used for, not what secures it. A car loan or credit card rolled into the home loan funded private spending, so the interest stays non-deductible. Keeping it in its own split makes it easier to target and stops it mixing with any investment borrowing. Your registered tax agent confirms the treatment.
You can, but every dollar sent to the investment strategy is a dollar not saving the car loan's higher rate. If the car loan is small or nearly finished, running both can make sense. If it has years to run at a high rate, clearing it first usually leaves more surplus for recycling later.
