What a feasibility template is

A feasibility template is a pre-built spreadsheet model — typically published by an industry body, university course or property consultancy — that you populate with your own project data.

What a good template looks like

  • AU-specific cost stack — GST, contributions, finance.
  • Monthly cashflow, not just annual.
  • Output set including profit on cost, margin, IRR, peak debt.
  • Structured input section, not formulas spread across the sheet.

When to skip the template

A template is a frozen guess at how your project looks. The moment you change one assumption, the formulas have to absorb it — which is where templates break. If you're running more than two or three feasibilities a month, a structured tool will save you time within a month.
