How to use these renovation cost calculators
Each renovation cost calculator works the same way: choose the options that match your project, enter your size or area, and select your city. The tools apply current Australian supply and labour rates and adjust for regional differences, giving you a realistic low-to-high range to budget against before you call in the trades.
How much do renovations cost in Australia?
Renovation costs vary widely by project and finish. As a rough guide, new flooring runs about $45–$255 per square metre installed, a full bathroom renovation $18,000–$35,000, a mid-range kitchen $25,000–$45,000, and a professional repaint $20–$105 per square metre of floor area. Your location, the condition of your home, and how much structural, plumbing or electrical work is involved all move the final figure.
