What's inside
Builder / Renovation cost calculators turn a curious website visitor into a qualified lead in under three minutes. Each tool prices the job using your actual rates, includes GST automatically, and delivers a branded PDF estimate to the customer the moment they submit — while sending you their name, phone and suburb in real time.
Every builder / renovation calculator is built around the way Australian tradies actually quote. Set your hourly rate, material costs and minimum job fee once, embed the calculator on your website with a single line of code, and let it qualify leads around the clock — including weekends, after-hours and while you're on the tools.
Our 2 builder / renovation calculators include full quote estimators.
Calculators are reviewed against current Australian builder / renovation material costs and labour rates. Defaults are pre-filled with national averages; every variable can be overridden to match your local market.

Builder / Renovation cost calculators — estimate jobs and capture leads online
Builder / Renovation jobs vary widely in cost depending on scope, materials, and site access. These calculators give customers a realistic estimate in minutes — and give you a qualified lead with a job value attached the moment they submit.
- How are builder / renovation estimates calculated?
- Each calculator uses industry-standard formulas covering materials, labour, travel, and GST. You enter your own rates and markup, so every estimate reflects your actual pricing rather than a generic national average.
- What information does the customer need to provide?
- Basic job details — dimensions, location, scope, and any special requirements. The calculator guides them step-by-step and adjusts the estimate in real time as they answer.
- What happens after a customer submits?
- You receive an instant email with their name, phone, suburb, and estimated job value, plus a branded PDF of the full breakdown. The lead also appears in your Leadkit dashboard for follow-up and can sync to your CRM.
- Is the calculator accurate for Australian pricing?
- Formulas are reviewed regularly against current builder / renovation material costs and labour rates across Australia. Defaults reflect national averages; you override any value to match your suburb, supplier prices and minimum job fee.
- Can I customise the calculator for my business?
- Yes — set your own rates, upload your logo, choose your brand colour, add your ABN and contact details. Customers see a fully branded experience that matches your website, not a generic third-party tool.
- How do I add the calculator to my website?
- Copy the embed snippet from your Leadkit dashboard and paste it into any page. It works on WordPress, Webflow, Squarespace, Wix, Shopify and custom-built sites. No website? We auto-generate a quote page at leadkit.com.au/quote/your-business that you can share on Instagram, Google Business Profile or your email signature.
