Compare a resale scenario.
Enter your own assumptions to see the arithmetic.
The starting amounts are examples, and the assumed sale-price change comes from you.

This is a scenario calculation, not a forecast or property valuation.
I'm not a financial adviser or property valuer, so I keep this tool to arithmetic for your planning brief.
A qualified valuer or licensed financial adviser can help assess your property and financial circumstances.

I can pass your enquiry to a local Sydney renovator who can assess the site and prepare a written quote.

The calculator adds your renovation spend and other project costs, then subtracts that total from the sale-price change you enter.
Cost recovery is your assumed sale-price change divided by total project cost, while return on cost is the net difference divided by total project cost.
The tool has no property sales dataset, suburb multiplier or automated valuation; changing the assumed uplift changes the outcome because you're supplying that assumption.
A qualified valuer can assess comparable properties, while a licensed financial adviser can help with the broader financial decision.
Before choosing a spend assumption, review the scope questions in the bathroom budget guide.
For a smaller scope to discuss with a contractor, read the bathroom makeover guide.

Questions about this tool.
Does the calculator predict what my home will sell for?
No, it compares the figures you enter; the starting amounts are examples and the output isn't a valuation or a forecast.
Why can cost recovery and return on cost differ?
Cost recovery compares the assumed uplift with the cost, while return on cost first subtracts the cost; recovering 100% of a project cost produces a 0% return in this simple scenario.
Can I test a lower sale-price outcome?
Yes, enter 0 or a negative sale-price change to explore how the arithmetic changes, and include other project costs you want to consider.
