Estimate the difference between your property value and loan balance, then see what portion may be usable under a selected LVR.
Equity estimate
Estimate how much usable equity you may have.
Compare your property value with your current loan balance and a target lending limit.
Short explanation
Understanding home equity
Equity is simple to estimate but harder to use. Lenders still need to check valuation, borrowing capacity, purpose, and policy before equity can support a loan change.
How home equity works
Home equity is the difference between what a property may be worth and what you still owe. If a property is worth $950,000 and the loan balance is $590,000, the total equity estimate is $360,000.
Usable equity is usually lower than total equity because lenders generally want a buffer between the loan balance and the property value.
Total equity vs usable equity
Total equity is a simple property value minus loan balance estimate. Usable equity applies a lending limit, such as 80% LVR, and then subtracts the current loan balance.
Borrowing above common LVR limits may still be possible in some situations, but it can involve mortgage insurance, tighter policy, or different lender appetite.
Ways people use equity
Borrowers may explore equity for renovations, investment property deposits, upgrades, debt consolidation, business cash flow, or restructuring an existing home loan.
The purpose matters because lenders assess risk, documentation, repayment capacity, and acceptable loan structure differently.

Estimate basisHow this equity estimate works
This page estimates total and usable equity, then makes clear that lender valuation, purpose, and servicing still decide the real pathway.
- Total equity is estimated as property value minus current loan balance.
- Usable equity is estimated by applying the selected LVR limit to the property value, then subtracting the current loan balance.
- The calculator does not confirm a lender valuation, borrowing capacity, acceptable purpose, mortgage insurance position, or approval.
- A broker should compare whether equity is best reviewed through a top-up, refinance, split loan, construction pathway, investment loan, or debt consolidation review.
Frequently asked questions
Home equity calculator FAQ
How much equity can I use?
A common first estimate is property value multiplied by a target LVR, less the current loan balance. The amount a lender will actually allow depends on valuation, servicing, purpose, and policy.
Can I use equity to buy an investment property?
Possibly. A lender still needs to assess deposit, borrowing capacity, rental income treatment, existing debts, and the full investment loan structure.
Does usable equity mean I am approved?
No. Usable equity is only an estimate. Approval requires lender assessment, valuation, documents, credit checks, and policy fit.
What LVR should I use for an equity estimate?
Many borrowers start with 80% because it is a common benchmark, but the right limit depends on loan purpose, lender, property, and mortgage insurance.
Should I refinance to access equity?
It can be worth comparing if your current lender, rate, or structure is limiting. Switching costs and the new loan setup should be weighed against the benefit.
When you're ready to use equity
A calculator gives you a starting number.
Check whether usable equity is actually usable.
Treat the equity figure as an estimate. A broker still needs to check valuation, usable equity, loan purpose, repayments, lender limits and policy before you rely on it.
- Confirm valueAn online estimate is not the same as a lender valuation. Property type and location can change the view.
- Test servicingEven with equity, lenders still need to assess income, expenses, credit commitments, and loan purpose.
- Compare structureA broker can compare top-up, split loan, refinance, construction, investment, or consolidation structures.
This calculator provides a general estimate only. It is not approval, credit advice, valuation advice, or a loan recommendation. Actual usable equity depends on lender policy, valuation, income, expenses, purpose, loan type, LVR limits, mortgage insurance, documents, and verification.
