Divorce Asset Split Calculator Australia
Build a current joint balance sheet, enter a proposal percentage and test how retained assets and assumed debts might be equalised. The percentage is your scenario, not a legal entitlement or prediction. Australian property settlements require disclosure, valuation and consideration of contributions, current and future circumstances, family violence and whether an order is just and equitable.

The result does not decide the proper percentage, asset ownership, tax, transaction, super-splitting or implementation terms. Obtain independent legal and financial advice.
The calculator only solves a proposed balance sheet
The page first totals the current values entered for real property, cash, investments, business interests, vehicles, personal property and superannuation. It subtracts the entered liabilities and agreed cost allowance. The resulting net pool is multiplied by Party A’s user-entered proposal percentage; Party B receives the balance to 100%.
Party A’s pre-equalisation net position is the gross assets proposed to be retained minus the liabilities proposed to be assumed. Party B’s position is derived from all remaining assets and liabilities. The equalisation amount is the difference between Party A’s target and current retained net position.
Party A target: net pool × entered Party A percentage.
Party A retained net: gross assets retained by A − liabilities assumed by A.
Equalisation: Party A target − Party A retained net. A positive result moves value from B to A; a negative result moves value from A to B.
“Moves value” does not automatically mean a cash payment. Implementation could involve a property transfer, refinance, sale proceeds, investment transfer or superannuation split. Each has legal, liquidity, tax, lender and timing consequences. Super is not converted into immediately accessible cash by this arithmetic.
There is no automatic 50–50 rule or calculator percentage
The Family Law Act directs a court to identify existing legal and equitable interests in property and liabilities, consider relevant contributions and current and future circumstances, and make an order only where it is just and equitable. The legislation addresses married and eligible de facto relationships through related provisions. The facts, evidence and discretion matter.
Contributions can be financial or non-financial, direct or indirect, and can include homemaker and parenting contributions. Current and future circumstances can include age, health, income, earning capacity, care of children, commitments and other legislated considerations. The weight and interaction of those matters cannot be reduced to one universal formula.
Reforms commencing on 10 June 2025 placed clearer property provisions in the Act, including duties of disclosure and express treatment of the economic effect of family violence where relevant. Companion animals also have a specific statutory framework. A percentage selected on this page cannot assess evidence, causation, safety or judicial discretion.
Full and frank disclosure comes before division
Financial and property matters carry duties of disclosure. The Court’s guidance describes disclosure of total direct and indirect financial circumstances, including income, property, financial resources, corporations, trusts and relevant disposals. Failure to disclose can have serious procedural and substantive consequences.
A joint balance sheet should itemise each asset and liability, current value, ownership, evidence and any competing value. Bank and loan statements, title searches, company or trust records, tax returns, super statements and transaction histories can be relevant. Mark an unknown item for investigation rather than entering zero.
The inputs here are category totals for scenario arithmetic; they are not a substitute for an itemised schedule. A $100,000 “investments” line cannot reveal whether parcels, cost bases, tax liabilities or ownership are agreed. Keep the detailed source sheet and use consistent valuation dates.
| Category | Value question | Common evidence |
|---|---|---|
| Real property | Current agreed market value and secured debt | Joint valuation, title and lender statements |
| Business / trust | Interest, control, maintainable earnings and tax | Accounts, returns, deeds and expert valuation |
| Superannuation | Fund interest and prescribed valuation | Fund information, statements and specialist method |
| Personal property | Current realistic value, not insured replacement cost | Appraisal, sale evidence and agreed schedule |
| Liabilities | Current enforceable balance and purpose | Statements, contracts and transaction records |
Valuation date and method can change the pool
Property proceedings commonly require current values, not simply values at separation. Markets, loan balances, businesses and super can change while negotiations continue. Contributions and post-separation events may also require legal analysis. Record the date beside every value and update the model when the evidence changes.
One party’s real estate appraisal and the other’s estimate can differ substantially. If a material item is disputed, the Court’s guidance encourages appropriate valuation evidence and, where possible, agreement on a valuer or court expert. A midpoint chosen for convenience may conceal a large negotiation issue.
Home contents in a family-law balance sheet are generally considered at realistic current value rather than insured new-replacement value. Vehicles likewise need current market evidence and finance. Business interests, defined-benefit super, overseas property, cryptocurrency and trusts can require specialist investigation.
Equal dollars may not deliver equal usable value
A home, cash account, business interest and super balance have different liquidity and risk. A person retaining a property may need lender approval and sufficient income to refinance. Superannuation is usually preserved. A business can require working capital and may be difficult to sell. The calculator values each entered dollar equally because it cannot price those differences.
Capital gains tax, transfer duty concessions, sale costs and other tax outcomes depend on ownership, asset history, orders, agreements and later events. Potential tax liabilities are not automatically deducted in every matter. Enter a cost allowance only where the treatment and amount are supported by advice; otherwise show it as a separate sensitivity.
Implementation documents matter. An informal transfer or cash payment may not finalise claims and can create avoidable tax or title problems. Consent orders and binding financial agreements have different legal requirements. Each party should obtain independent advice before signing or transferring property.
Time limits and process should be checked early
Property proceedings can be started before a divorce is final. The Court’s practice direction states that, unless leave or consent applies, married parties generally commence within 12 months after a divorce order takes effect, while de facto proceedings generally have a two-year period after breakdown. Jurisdictional and eligibility rules can be complex, and late applications require legal consideration.
Before court proceedings, pre-action procedures, dispute resolution and disclosure may apply, subject to exceptions such as urgency or safety. A negotiated proposal should still be tested against complete evidence and documented in an enforceable form. Delay can change values, finance capacity and risk.
A careful scenario workflow
Create an itemised balance sheet with documents and current dates. Separate agreed items from disputed or unknown items. Obtain valuations where the difference could alter decisions. Ask a lawyer to explain the relevant contribution and current/future-circumstance analysis before selecting proposal percentages.
Run more than one implementation scenario. A 55% share made up largely of inaccessible super is not the same cash-flow position as 55% with housing and liquid assets. Add refinancing limits, sale timing, tax advice and living budgets outside the pool calculation. Test what happens if a disputed value moves.
When a proposal is reached, reconcile every asset, liability and super interest to the implementation documents. The retained gross assets and liabilities in this page must allocate the full entered pool; the calculator derives Party B as the remainder. Check that no account, debt or transaction is omitted and obtain independent advice before finalisation.
Property settlement calculation questions
Does Australian law split divorce assets 50–50?
No automatic percentage applies. The Act requires identification of property and liabilities, consideration of contributions and current/future circumstances, and a just and equitable outcome.
Does this calculator choose a fair percentage?
No. The user supplies the percentage only to compare a proposal. Legal advice and evidence are needed to assess an appropriate outcome.
Should superannuation be included?
Super interests can be relevant property and may be split under specific rules. They remain subject to super law and may require prescribed valuation; they are not ordinary cash.
Which value should I use for household contents?
Use a realistic current value for the family-law balance sheet, supported where material. Do not use a home-insurance new-replacement total without advice.
Can a spreadsheet finalise the settlement?
No. Informal arithmetic does not necessarily prevent later claims or implement property and super transfers. Obtain advice on consent orders or agreements.
What if an asset or debt is unknown?
Mark it for disclosure or valuation rather than entering zero. A complete current pool is essential before an equalisation result is meaningful.
