What is equity

Equity is the difference between your property value and total secured debts. It shows your current position in the property before lenders apply serviceability checks.

What is usable equity (usable equity 80 percent rule)

Usable equity is the portion of equity available below your chosen target LVR threshold. In Australia, 80% LVR is a common benchmark to reduce LMI exposure, but lender policy can vary.

People often refer to this as the usable equity 80 percent rule. It can support equity to refinance Australia planning, but should still be validated with serviceability and repayment checks.

How lenders assess usable equity

Step 1 — Bank valuation may differ from your estimate.
Step 2 — LVR limits apply (often 80%).
Step 3 — Existing debts reduce usable equity.
Step 4 — Borrowing capacity must still be approved.

This calculator estimates usable equity only and does not guarantee lender approval.

Equity vs borrowing capacity

Equity is your asset position in the property. Borrowing capacity is how much a lender may approve after assessing serviceability and policy.

These are not the same. You can have usable equity and still be limited by income, living costs, existing debts, dependants, buffers, and lender rules.

Next step: run Borrowing Capacity Calculator.

How this equity calculator works

The calculator adds your current loan balance and other secured debt, then compares that total against your property value to estimate equity and usable equity.

Total secured debt = current loan balance + other secured debts
Equity = property value − total secured debt
Current LVR = total secured debt ÷ property value
Usable equity = max borrow at target LVR − total secured debt (minimum 0)
