Usable equity is your property value multiplied by your chosen lending limit, less what you owe.
The default limit is 80% of the value, because lenders mortgage insurance usually applies when you borrow more than that.
Taking off a buffer shows an amount you could consider recycling, not an amount you should.
Lenders also assess your income, expenses and their own valuation, so equity alone does not mean approval.
A broker can check your real figures before you plan around them.
How the Calculator Works
Enter your property value, your current home loan balance, the highest loan-to-value ratio (LVR) you want to stay under and any buffer you want to keep.
Current LVR: your loan balance divided by the property value.
Usable equity: the property value multiplied by your chosen LVR, less your loan balance.
Amount you could consider recycling: usable equity less your buffer.
If a result falls below zero, the calculator shows $0. To see where this number fits in the wider strategy, read our guide to debt recycling.
A Worked Example
Take a home valued at $900,000 with $480,000 owing and a $20,000 buffer. The current LVR is 53.3%.
Step
80% limit
70% limit
Lending limit (value x LVR)
$720,000
$630,000
Less loan balance
$480,000
$480,000
Usable equity
$240,000
$150,000
Less buffer
$20,000

$130,000
A lower limit leaves more equity untouched if values fall or your plans change.
Why 80% Is the Default
Moneysmart explains that lenders mortgage insurance (LMI) is usually a one-off cost when you borrow more than 80% of a property's value. It protects the lender, not you.
Staying at or under 80% generally avoids that cost, and you can set a lower limit for more room. For how equity builds and why you can start small, read how much equity you need.
What Equity Does Not Show
A positive result shows room under your limit. It does not show what a lender will approve.
Serviceability: the lender checks that your income can support the extra borrowing after expenses and other debts.
Valuation: the lender relies on its own valuation, which can differ from your estimate.
Investment risk: borrowing to invest can magnify losses, and the debt remains if the investment falls.
How the equity is drawn matters as much as how much there is. Our loan structure and splits page shows how we keep the investment borrowing separate.
Next Steps With Your Number
Bring your result to a free first call by phone or video. We talk through your goals, current loan, income and savings, and you come away knowing whether the lending side looks workable.
Your financial adviser decides how much, if any, to invest and in what.
Your accountant or tax agent confirms the tax treatment.
The calculator turns your property value and loan balance into a usable equity figure under the limit you choose. Treat it as the ceiling for a conversation, not a target to borrow up to.
Approval still depends on your income, the lender's valuation and its policy, so have the number checked before you plan around it.
Have Your Equity Checked

There is no set minimum. What matters is your usable equity under your lending limit, whether your income supports the extra borrowing and how much your adviser suggests investing. You can also recycle in smaller amounts over time.
It is the part of your property value you could borrow against under a chosen loan-to-value ratio, less what you already owe. At an 80% limit on a $900,000 home with $480,000 owing, it is $240,000.
Some lenders lend above 80%, but lenders mortgage insurance is usually payable once you borrow more than 80% of the property's value. Borrowing more also leaves less room if values fall.
No. Lenders also assess your income, expenses and other debts, and rely on their own valuation. Equity is one part of the assessment.
That depends on your income, expenses and plans, and is worth agreeing with your financial adviser. The calculator subtracts whatever buffer you enter.
