Rolling credit cards and car loans into your home loan can cut the rate. The calculator shows whether it also cuts the total interest, or just stretches it out.
Keep separate: each debt runs at its own rate and repayment, showing months to clear each and total interest.
Consolidate, same repayment: the balances join the home loan at the home loan rate, and you keep paying the same combined amount until they are cleared.
Consolidate over the loan term: the balances are spread over your remaining home loan term, giving a much lower repayment.
A warning appears when the third option costs more in total interest than keeping the debts separate. Enter up to four debts.
A Worked Example
Illustrative figures only: a $10,000 card at 20% with $300 a month, a $25,000 car loan at 9% with $520 a month, and a 6% home loan with 25 years left.

About $4,500
Consolidate over 25 years

The lower rate only helps if the repayment stays up. Spread over 25 years, the same $35,000 costs about three times the interest of keeping the debts separate.
Assumptions and Gaps
Rates stay the same, and interest is charged monthly.
No new spending on cleared cards.
Repayments on each debt stay steady, although card minimums often fall with the balance.
No fees: refinance costs, discharge fees, valuation fees or break costs on fixed loans.
No credit assessment. Lenders look at income, expenses, equity and how existing debts have been managed.
Consolidating also turns unsecured debt into debt secured by your home. If repayments are missed later, the home is at risk, not just your credit file. Closing cleared card accounts stops the balances building again.
Consolidation and Debt Recycling
Consolidated debt is private debt, so its interest is generally not deductible. It belongs in its own split, away from any investment borrowing, so the records stay clean.
If you need consolidation to manage repayments, debt recycling may not suit yet. Adding investment debt while consumer debt is being cleared puts more strain on a stretched budget. Our article on clearing consumer debt before debt recycling covers the order.
It saves interest only if you keep repaying at a similar pace. The home loan rate is usually lower than card or car loan rates, but spreading the balance over 20 or 30 years can cost far more in total interest. Fees to refinance or break fixed loans also count. The calculator compares both outcomes.
It can. Consolidation uses equity and raises your home loan balance, which leaves less room for an investment split. Lenders also look closely at recent consumer debt when assessing new borrowing. Many people clear consolidated debt first, then start recycling once the budget has room.
Talk to your lenders early, as they have hardship processes. The National Debt Helpline on 1800 007 007 offers free, confidential financial counselling. A consolidation loan can help in some cases, but it is not the right first step for everyone, and new borrowing may not be approved while repayments are being missed.
General information only, not financial, tax or legal advice. We arrange the lending; we do not recommend specific investments, and your financial adviser and registered tax agent should guide the asset and tax decisions. Debt recycling is a leveraged strategy that uses your home as security and can amplify losses. Any figures shown are illustrative, based on stated assumptions, and not a promise of any result. Consider your circumstances and seek advice from a licensed broker, financial adviser and registered tax agent.
1. Arranged a loan when our small business situation made it difficult to qualify. 2. Met requirements to have funding available by a specified date. 3. Understood my needs to setup debt recycling to allow tax structuring. 4. Communicated well throughout.
I would use their services again.
