How it works on a firm’s website

A firm can run this in one of two ways. Either way, the firm sends the formal quotation, and the visitor is told the estimate is only a rough guide.

Instant version (this demo): the visitor sees a rough range at once. The firm receives their details with that range and follows up with a quotation.

Approval version: the visitor sees no price. The firm gets an email with a link to confirm. When the firm approves, the estimate is emailed to the customer automatically. Nothing reaches the customer before that, and the firm can change the range first.

These are previews only. Nothing is sent from this demo, and the approval version here shows sample emails.

How to use this calculator

  1. About the home: choose the property type, finish level and number of bedrooms, enter the floor area and how many bathrooms you want to renovate.
  2. What is included: tick the work you want done, from hacking and tiling to carpentry, doors, windows, air-conditioning and cleaning, and choose the level of kitchen work. Hacking and demolition is usually needed for resale homes.
  3. Your rough range updates as you change anything, along with where the money goes and your biggest saving. It is a guide for planning, not a quotation.
  4. Copy share link reopens these exact choices, handy for sending to a partner or a contractor.
  5. The renovation firm reviews your details and sends you a formal quotation.

How it is calculated

Whole-home work is priced per square foot. Built-ins, doors, air-conditioning and similar items are priced per item or per room, so your bedrooms and bathrooms change the total. Everything is then multiplied by the property type and, for most items, the finish level. The total is shown as a range of 15% either side. These are sample rates for the demo, not market prices.

Your biggest saving compares changes such as one finish level lower, a simpler kitchen, or leaving out an item, and shows the one that cuts the budget most.

Not included unless you tick them: furniture, loose appliances, GST, and any structural work or permits. Real quotations depend on the site, the layout, the materials and the contractor.
