How this is calculated

The calculator applies broad planning multipliers for project type, finish level, access complexity and contingency. It is an indicative guide only, not a quote or professional advice.

NSW residential building work may require licensed trades and written scope details. Check current obligations with NSW Fair Trading (the state building and consumer regulator) before committing to a contract.

Assumption set

  • Indicative only: calculator outputs and checklist prompts are planning aids, not a quote or building advice.
  • Renovation costs vary with site access, structural work, cabinetry, wet-area scope, finishes, approvals and supplier availability.
  • Timeline notes assume normal trade sequencing; strata, heritage, engineering, approvals or defects can extend the programme.
  • A written site quote from the independent provider takes precedence over any figure or checklist item on this page.
