Equity Recycling Calculator

What equity recycling is (the property version)

Search "equity recycling" and most of what you find is a shares strategy: pay down the home loan, redraw the money, buy ETFs, convert non-deductible debt into deductible debt. Useful, but not what property investors mean by the term.

The property version is simpler and older: buy, let equity build, refinance to release it, use the release as the deposit on the next property, repeat. Each property in the portfolio grows, the growth becomes usable equity, and the usable equity becomes the next deposit. You never save another cash deposit after the first property; the portfolio funds its own expansion. That loop is the engine behind most multi-property portfolios in Australia, and it is the loop this calculator runs.

The arithmetic that makes it work: usable equity is your portfolio's value multiplied by the lender's LVR cap (normally 80%), minus your total debt. Every year of growth adds 80 cents of usable equity per dollar of value gained, across every property you hold. Three properties growing at 6% build the next deposit three times faster than one.

The buy, refinance, repeat sequence, step by step

1. Establish the base. Your home (or first investment property) grows and its loan gets paid down, until the value times 80% minus the debt reaches about 25% of your target purchase price. On the calculator's example figures, a $950,000 home with $520,000 owing already has $240,000 usable: enough for a $600,000 purchase with room to spare. Check your own number with the usable equity calculator.
2. Release the equity. A top-up or a new loan split against the existing property releases 25% of the next purchase price: 20% for the deposit, roughly 5% for stamp duty and costs. Keep it as a separate split, not blended into the home loan.
3. Buy with an 80% stand-alone loan. The new property carries its own loan for 80% of its price, secured only by itself. Combined with the release, the purchase is 105% debt-funded and zero cash out of pocket.
4. Hold and let the portfolio grow. Now two properties are growing instead of one. Rent helps carry the interest; the tax position usually softens the rest in the early years.
5. Revalue and go again. When usable equity across the whole portfolio reaches 25% of the next (now more expensive) target price, release and repeat. The calculator enforces at least 12 months between purchases, which is roughly the fastest lenders and valuers let this move in practice.

Notice the flywheel in step 4: the trigger tests equity across everything you own. Early purchases are slow because one property is doing the growing. Later purchases come faster because four or five properties are compounding at once. Then the purchases stop mattering and the compounding takes over, which is what the back half of the chart shows.

Why the 105% debt structure, and why uncrossed

Funding 105% of the purchase with debt sounds aggressive until you see what it replaces. The alternative is saving a $150,000 cash deposit per purchase, which at most household savings rates means one property every five to eight years instead of the sequence above. The equity is already yours; the structure just puts it to work.

The structure matters as much as the amount. Done properly it is two separate loans:

• An equity release split of about 25% of the price, secured against the existing portfolio;
• A stand-alone loan of 80% of the price, secured only by the new property.

Both loans fund investment, so the interest on both is generally deductible, and keeping the release in its own split keeps that clean at tax time.

The worked example, end to end

The prefilled scenario: $950,000 home with $520,000 owing, buying $600,000-class properties (in today's dollars), 6% growth, 80% LVR, 15 years. Here is the purchase timeline the model produces:

Two things worth noticing. First, the gap after property 2: purchases 1 and 2 fire back to back because the home had years of stored equity, then year 3 is a forced pause while the enlarged portfolio rebuilds its buffer. That rhythm, a burst then a wait, is what the strategy feels like from the inside. Second, look at the last row: from year 7 the model buys nothing, and equity still triples by year 15. The buying phase builds the machine; the holding phase is where most of the money is made.

And the honest caveat, again: this timeline assumes a lender says yes six times in seven years. On a real income, they will not. The value side supports this sequence; the income side decides the actual pace.

The three walls

Every recycling sequence runs into at least one of these. Plan for all three.

1. The serviceability wall

Lenders assess every application at your actual rate plus a 3 percentage point buffer, the floor APRA requires. Around a 6.5% actual rate you are tested at roughly 9.5%, on the entire debt stack, with rental income shaded to about 80%. Each 105% purchase adds a big slab of assessed repayments, so most investors' borrowing capacity runs out somewhere around property 2 or 3, years before their equity does. The fixes are income growth, rent growth, paying down debt, or a lender whose policy suits your file, which is broker work. Hitting this wall mid-sequence is the normal experience, not a sign the strategy failed.

2. The flat years

The model grows every property 6% every year. Real markets do nothing of the sort: they deliver a decade's growth in three or four good years and pad the rest with flat patches and small falls. A three-year flat patch adds three years between purchases and tests whether you can hold. This is exactly why we buy through cycles rather than trying to time them: because growth is lumpy, the entry that matters is buying a good asset at a fair price in a market with sound fundamentals, then giving it time. Miss the burst years because you were waiting for certainty and the whole timeline stretches.

3. Rate rises

The sequence deliberately accumulates debt: in the worked example, $5.1 million of it. A 1 percentage point rate rise on $5.1 million is $51,000 a year of extra interest, before tax relief. Rises hit the whole stack at once while rents adjust slowly. The defences are boring and non-negotiable: a cash buffer measured in months of total interest, fixed-rate portions where they make sense, and never sizing the next purchase off the assumption that today's rate holds.

When not to recycle

This strategy is not for every balance sheet, and pushing it when the foundations are thin is how people lose properties. Do not start (or continue) the loop when:

• Your cash buffer is thin. If you hold less than several months of total loan interest in cash or offset, a vacancy plus a repair bill plus a rate rise arrives as one event. Build the buffer before the next purchase, not after.
• Your income is unstable. Interest-only debt across multiple properties assumes the interest always gets paid. Commission-heavy, contract, or single-income households need a bigger buffer and a slower sequence.
• You are already at high LVR. Recycling from a portfolio already at 85% or 90% LVR means paying LMI to release equity and leaves no room for a valuation to come in soft. The strategy works from 80% and below.
• The plan needs everything to go right. If the numbers only work at 7% growth, full occupancy, and today's rates, they do not work. Model the flat patch and the rate rise before you sign anything.

Waiting a year to start from a stronger base costs you almost nothing over a 15-year horizon. Being forced to sell in year 3 costs you the strategy.
