About the Selling Property Cost Calculator
Selling a property comes with more costs than most people expect — agent commission, marketing, conveyancing and paying out the remaining mortgage all come off the top before you see any proceeds. Many sellers budget for the commission and forget the rest: professional photography, a listing on the major portals, signboards, and sometimes styling or minor repairs to get the property presentation-ready, all of which are typically paid upfront regardless of whether the sale price meets expectations. This calculator adds those costs up against your expected sale price to show what you'd actually walk away with.
How it works
Agent commission is calculated as a percentage of the sale price. That's added to marketing and legal costs to get your total selling costs. Net proceeds = sale price − total selling costs − remaining mortgage owing.
Assumptions and behaviour
- Agent commission is a flat percentage of the final sale price — real agreements sometimes use tiered or fixed-fee structures.
- Marketing and legal costs are entered as flat dollar figures — get quotes from your agent and conveyancer for accurate numbers.
- Doesn't subtract capital gains tax — that's calculated separately based on your personal tax situation.
Limitations
- Capital gains tax isn't included — for an investment property, this can be a significant cost; speak to a tax professional.
- Mortgage discharge fees and any break costs on a fixed-rate loan aren't included — add them to the mortgage figure if relevant.
- Real agent commission rates vary by state, agency and negotiation — treat the default as a starting point only.
- Auction costs (auctioneer's fee, sometimes charged separately from commission) and styling/staging costs aren't broken out as their own line — fold them into the marketing or legal cost fields if they apply to your sale.
