Home Equity Calculator
Find out how much equity you've built and how much of it a lender will actually let you access — for a renovation, an investment property deposit, or consolidating expensive debt.

Estimate only. Access depends on a lender valuation, your income and the purpose of the funds. Going above 80% LVR triggers Lenders Mortgage Insurance.

How usable equity is calculated
Take 80% of your property's value and subtract what you still owe. That's the amount most lenders will release without Lenders Mortgage Insurance. For example, a home worth $950,000 with a $480,000 loan has $470,000 of raw equity but roughly $280,000 of usable equity at 80% LVR.
Equity is only half the test
Lenders assess two things: security (do you have enough equity?) and serviceability (can you afford the bigger repayment, tested at roughly 3% above the actual rate?). Plenty of homeowners are equity-rich but fail on servicing — which is where structuring the loan correctly, or choosing a lender with a more generous assessment, makes the difference.
Smart ways to use equity
- Renovate — often adds more value than it costs, and stays at home loan interest rates.
- Buy an investment property — use equity as the deposit rather than saving cash again.
- Consolidate debt — replace 15–20% credit card interest with home loan rates, but keep the term short so you don't pay more overall.
- Landscaping and outdoor work — a common cash-out purpose that lenders will fund with quotes.
Structuring matters
Released equity is usually set up as a separate split or sub-account rather than mixed into your existing loan. That keeps investment-purpose borrowing clearly separated from owner-occupier debt, which makes tax reporting far cleaner if the funds are used to invest.
Key terms explained
The main terms used in this calculator and its results.
- Equity
- The difference between your property's market value and the amount you still owe on your loan.
- Lenders Mortgage Insurance (LMI)
- A one-off premium that protects the lender (not you) if you default, typically required when borrowing more than 80% of the property value.
- Line of Credit
- A revolving loan secured against your property that you can draw on up to an approved limit, paying interest only on what you use.
- Loan-to-Value Ratio (LVR)
- Your loan amount expressed as a percentage of the property's value. A lower LVR generally means better rates and no LMI.
- Refinancing
- Replacing your existing home loan with a new one — often to get a lower rate, better features or to access equity.
- Serviceability
- A lender's assessment of your ability to comfortably afford loan repayments, based on your income, expenses and debts.
- Usable Equity
- The portion of your equity a lender will normally release — typically 80% of the property's value less your current loan balance.
