About the Property Selling Cost Calculator

A property selling cost calculator Australia helps homeowners and investors estimate the total costs involved in selling a property, including agent commissions, marketing fees, legal costs, and mortgage discharge fees. Understanding these costs is essential for calculating your net proceeds and planning your next property purchase. The ATO considers selling costs when calculating capital gains tax.


What is the Property Selling Cost Calculator?

This calculator estimates all costs associated with selling a property in Australia, providing a clear breakdown of fees and net proceeds. Selling costs typically include real estate agent commission, which ranges from 1.5% to 3% of the sale price plus GST, marketing and advertising expenses, professional photography and styling costs, conveyancing or solicitor fees, mortgage discharge and early repayment fees, and pest and building inspection reports for the buyer. The calculator inputs the expected sale price, agent commission rate, marketing budget, legal fees, and any outstanding mortgage balance. It shows the total selling costs as both a dollar amount and a percentage of the sale price. It also calculates the net equity you will receive after all costs and mortgage repayment. Australian property sellers use this tool to decide on an asking price, negotiate agent fees, and understand their net position before listing. This is particularly important when selling one property to fund the purchase of another.

Worked Australian Example

Practical Example

Rebecca is selling her three-bedroom house in Townsville, QLD with an expected sale price of $520,000. She has an outstanding mortgage balance of $180,000. Her real estate agent charges 2.5% commission plus GST. Marketing costs are $3,500, legal fees are $1,800, and mortgage discharge fees are $350. Using the calculator, she enters $520,000 as sale price, 2.5% as commission, $3,500 marketing, $1,800 legal fees, $350 discharge, and $180,000 mortgage balance. Agent commission is $13,000 plus $1,300 GST, totalling $14,300. Total selling costs are $3,500 plus $1,800 plus $350 plus $14,300, equalling $19,950. Net proceeds before mortgage repayment are $500,050. After repaying the $180,000 mortgage, Rebecca receives net equity of $320,050. She is pleased with this result and uses the figure as her deposit for her next home. The ATO will include the selling costs in her cost base if the property was an investment, reducing her CGT liability.
