Debt Recycling Explained: A Worked Example (Australia, 2026)

Debt recycling takes the least useful debt an Australian household has - the home loan - and turns it into the most useful kind: tax-deductible investment debt, without borrowing an extra dollar in total. It sounds like a trick, and the mechanics genuinely are that simple. What's harder to find is a plain-English answer to the question that actually matters: what does it cost, and when does it start paying off? This article works through real numbers using the debt recycling calculator.

The 30-second summary

• Debt recycling splits off home equity into a separate, interest-only investment loan, invests it, and makes that loan's interest tax-deductible.
• The tax refund plus the investment's own income get redirected onto the home loan as extra repayments - that's the "recycling."
• On a $200,000 tranche at a 6% loan rate and a 4% distribution yield, the net annual cost is about $2,720 on a $120,000 income - funded by future growth, not by cash flow alone.
• Redirecting that $9,280/year of tax refund plus investment income cuts 9.8 years and $162,768 of interest off a $400,000 home loan.
• If the distribution yield exceeds the investment loan rate, the strategy is cash-flow positive before any capital growth at all.
• It only works if the new loan is genuinely, cleanly separate from the home loan - mixing the two can cost you the deduction.

How debt recycling actually works

1. Split    Redraw or split off a fixed amount of home equity into a
            separate, interest-only investment loan.
2. Invest   Use that money only to buy income-producing assets - shares,
            ETFs, managed funds. Never mix it with personal spending.
3. Deduct   The investment loan's interest is now tax-deductible, because
            the money was used to produce assessable income.
4. Redirect Send the tax refund and the investment's own income onto the
            remaining (non-deductible) home loan as extra repayments.
5. Repeat   As the home loan shrinks and the property grows, more usable
            equity becomes available to split off into a new tranche.

Everything below models steps 1 through 4 precisely, for one fixed tranche. Step 5 - repeating the cycle as equity frees up - needs a property growth assumption this article deliberately avoids making for you; a broker or adviser can run that off your real numbers.

A worked example - $200,000 recycled from a $1,000,000 home

Item	Figure
Home value	$1,000,000
Home loan balance	$400,000 at 6.00% p.a., 25 years remaining
Amount recycled	$200,000 (of $400,000 usable equity at 80% LVR)
Investment loan	$200,000 at 6.00% p.a., interest-only
Expected distribution yield	4.00% p.a.
Taxable income	$120,000

This year's tax and cash flow:

Investment loan interest (deductible)	$12,000
Investment income (assessable)	$8,000
Net deduction	$4,000
Marginal tax rate (30% bracket + 2% Medicare)	32%
Tax saved	$1,280
Net annual cost of the strategy	$2,720

That net cost is the price of admission - it's real money leaving the household each year. What it buys, if redirected, is the home loan finishing years early:

	Without recycling	With recycling
Monthly home loan repayment	$2,577	$2,577 + $773 extra
Years to repay	25.0	15.3
Total interest paid	$373,162	$210,394

$9,280 a year - the $8,000 of investment income plus the $1,280 tax refund - redirected as extra repayments removes 9.8 years and $162,768 of interest from the home loan. That's the whole trade: $2,720/year out of pocket now, in exchange for a home loan gone nearly a decade sooner, plus whatever the $200,000 investment is worth by the time it's paid off.

When the numbers flip to cash-flow positive

The example above costs money because the 6% loan rate exceeds the 4% yield. Run the identical $200,000 tranche at an 8% distribution yield instead: investment income becomes $16,000, which is $4,000 more than the $12,000 of interest. That $4,000 is now extra taxable income rather than a deduction - $1,280 more tax at the same 32% marginal rate - but the household is still $2,720/year ahead in cash terms, before any capital growth is counted at all.

	4% yield (below loan rate)	8% yield (above loan rate)
Investment income	$8,000	$16,000
Tax effect	Saves $1,280	Costs an extra $1,280
Net annual position	−$2,720 (cost)	+$2,720 (benefit)

Yields reliably above a typical home loan rate are unusual for a diversified portfolio - most real debt-recycling plans sit closer to the first column and lean on capital growth, not yield, to be worthwhile over time.

Why the loan has to be split cleanly

This is the part that trips people up, and it's not optional. The ATO's test for deductibility looks at what the borrowed money was actually used for - not what the loan is labelled. A genuine debt-recycling structure splits the new borrowing off at the exact point the funds are drawn, and that money is used for nothing except buying income-producing assets.

If a redraw facility isn't tracked cleanly, or investment funds ever pass through an account that also covers personal spending, part or all of the interest can lose its deductible status - while the debt itself stays exactly where it was. Getting this right is a conversation with your lender and your accountant before any money moves, not something a calculator can verify after the fact.

The risk side

Debt recycling increases total borrowing against the home to fund an investment. That means:

• Investment risk sits against your house. If the portfolio falls in value, the investment loan and its interest don't shrink with it.
• Rate risk applies twice. A rate rise increases the cost on both the home loan and the investment loan at the same time.
• It's a long-horizon bet. The worked example above costs $2,720/year in year one. That cost has to be worn for years before capital growth, if it comes, makes the strategy worthwhile.

None of this makes debt recycling a bad idea - it's a standard, well-documented strategy that plenty of Australian households run successfully. It does make it a strategy to start with advice, not a spreadsheet.

Frequently asked questions

What is debt recycling?

Debt recycling replaces non-deductible home loan debt with tax-deductible investment debt, without increasing your total borrowing. You split off home equity into a separate loan, invest it, and the new loan's interest becomes deductible. The tax refund and the investment's own income are then redirected onto the home loan as extra repayments.

How much does debt recycling actually save in tax?

Tax saved equals the net deductible amount multiplied by your marginal tax rate. On a $200,000 tranche at a 6% loan rate and a 4% yield, that's a $4,000 net deduction worth $1,280/year at a 32% marginal rate.

Does debt recycling cost money or make money?

It depends on whether the distribution yield is above or below the investment loan rate. Below the rate, it costs money up front (about $2,720/year in the example above) and relies on capital growth. Above the rate, it's cash-flow positive immediately.

Why does the investment loan need to be structured separately?

The ATO looks at what the money was used for, not the loan's name. A clean split at the point of drawdown, used only for income-producing assets, is what keeps the interest deductible.

What's the risk in debt recycling?

Investment risk and interest-rate risk are both secured against your home, applied on top of your existing mortgage risk. It's a leveraged, long-horizon strategy - get advice before starting.

Can I keep recycling equity as the home loan shrinks?

In principle, yes - that's the "repeat" step. It needs a property growth assumption and a repeat decision each year or two, which is best modelled with a broker or adviser against your real numbers rather than assumed here.

Run your own numbers - home value, loan balance, recycled amount, and expected yield - in the debt recycling calculator. If you're weighing this against gearing into an investment property instead, see the negative gearing calculator, or for the lower-risk option of just paying the home loan down directly, the offset account explained guide.
