Common questions
What others asks before signing up?
How much does a builder renovation cost in Australia?
Builder renovations span a huge range. Cosmetic refreshes for a whole home are typically $20,000–$80,000; single-room major renos are $25,000–$80,000; multi-room renovations sit between $80,000 and $350,000; single-storey extensions are $150,000–$500,000; and knockdown rebuilds with a project home builder run $400,000–$1.2M for a 200–280m² home. Architect-designed custom builds easily reach $600,000–$3M+. The calculator gives an instant estimate for your specific scope, finish tier and property — your builder confirms the final price after a site visit.
How accurate is an online renovation quote calculator?
It uses real Australian per-m² rates from HIA Renovations Roundup and Master Builders cost data — combined with finish tier, property age, scope, council fees, access and live-in factors — to produce a close estimate. It's a price indication only. Renovations are inherently variable, so the realistic range typically sits ±20–25% around the headline number; your builder confirms the final price after a site visit and detailed scope review.
What's the difference between a renovation, an extension and a knockdown rebuild?
A renovation works inside the existing structure — refreshing rooms, updating finishes, sometimes moving non-structural walls. An extension adds new floor area to the existing home (a rear extension, a second storey, a granny flat) and typically runs $3,000–$5,500/m² because it's new construction. A knockdown rebuild demolishes the existing house and starts from scratch — project-home rebuilds run $2,500–$4,000/m² for the entire new build. The calculator routes each path to the right rate.
Do I need council approval for my renovation?
Most extensions, structural changes and any addition to floor area need a Development Application (DA) and building permit. Cosmetic refreshes and like-for-like internal renovations often don't. Council DA fees vary by state and project value but typically run $500–$3,000 plus consultant fees. The calculator adds a built-in council allowance when you flag that approval is required — your builder will confirm the exact pathway after a site visit.
Can I add this calculator to my own website?
Yes — embed it on WordPress, Webflow, Squarespace, Wix or Shopify with one snippet, or use the free hosted page if you don't have a site.
What do I get when someone uses my calculator?
A full lead: their name, phone, email, scope details (renovation type, area, finish tier, council, live-in, access) and the estimate they saw — plus a branded PDF copy in your inbox, ready to call back.
I don't have a website — can I still use it?
Yes. Every calculator gets a free hosted quote page with your branding and a shareable link for your Google Business Profile, socials or texts.
Is Leadkit really free?
Yes. Free lets you add up to 3 calculators to your website and receive 10 leads per month — no credit card. Every lead beyond the cap is still captured and held for you; upgrading to Pro ($29/mo) opens them all retroactively and removes the cap.
Do I need to know how to code?
No. You get an embed code (one line of HTML). Paste it into your website builder — Wix, Squarespace, WordPress, or any custom site. That's it.
How accurate are the price estimates?
You configure the calculator formulas to match your actual pricing. Leadkit provides the framework; you set the numbers. Estimates can be as detailed or as rough as you like.
What happens with lead data?
All lead data is stored securely in your workspace. You own it. We never sell or share your leads with anyone.
Can I use Leadkit as an agency for multiple clients?
Yes — our Agency plan lets you create and manage separate workspaces for each of your clients, all from one dashboard.
What's the difference between the plans?
Free: up to 3 calculators, 10 leads/month (over-cap leads held + locked until upgrade). Pro: unlimited leads, unlimited calculators, white-label, branded email sending, analytics, email templates. Agency: everything in Pro plus multi-workspace management.

How it works
How this builder renovation estimate is calculated
Each estimate combines a per-m² build rate with finish tier, property age, scope add-ons, council fees and any live-in or architect engagement, then applies GST. It produces an estimate, not a binding quote — your builder confirms the final price after a site visit.
GST handling: All estimates are shown GST-inclusive at the Australian rate of 10%.
1
Pick the renovation type
Cosmetic refresh, single-room, multi-room, extension or knockdown rebuild — each path uses its own typical Australian per-m² rate.
base_rate_per_m2 by renovation type
2
Apply finish tier and property factors
Builder's standard, mid-range, premium or luxury — combined with property age (older homes hit asbestos and old wiring) and property type.
Multiselect scope (structural, new kitchen/bathroom, rewire) adds a percentage. Council DA, architect fees and a live-in-during-reno premium are added if applicable.

Sydney and Melbourne sit at the top of these ranges (15–25% premium); regional areas are often cheaper on labour but may add a travel surcharge for trades.
