Turn a proposed percentage division of the net property pool into dollar amounts, and see what your share is worth after your own legal costs.
Under section 79 of the Family Law Act 1975, as amended from 10 June 2025, a court deciding a property settlement must identify the parties' existing property and liabilities, assess contributions (including the effect of family violence on a party's ability to contribute), consider current and future circumstances (including the effect of family violence and the care of children), and make only an order that is just and equitable. The result is usually expressed as a percentage of the net pool: all property, superannuation and financial resources the court treats as in the pool, less liabilities.
Enter the net pool, the share proposed for the other party, and your own legal and valuation costs. The calculator shows the other party's dollar share and what your remaining share is worth once your costs are paid.
Formula: other party's share = pool × percentage; your share after costs = pool − other party's share − your costs.
Worked example (illustrative): a net pool of $980,000, including $310,000 of combined super. An offer of 55/45 in your favour means the other party receives $441,000 and you receive $539,000. After $18,000 of your own costs, your share is worth $521,000. If you hold out for 57/43 and the extra negotiation costs $30,000 more, the 2-point gain ($19,600) is wiped out.
Limits: percentages are not set by formula and every case is different. The tool does not split super into the separate super component, value tax liabilities or allow for spousal maintenance. Read the property settlement worked example and get legal advice before signing consent orders.
