Trades calculators for Australian businesses — estimate, capture leads, win more jobs
Trades pricing varies by state, site conditions, materials and scope. These calculators let customers self-estimate in under three minutes, leaving you a qualified lead with a job value, contact details and suburb attached.
- What do trades calculators cover?
- Each calculator covers the most common trades job types — materials, labour hours, travel, GST at 10% and your margin. You set your rates once; the formula does the rest, including showing the customer an estimate range rather than a single price.
- How does the lead capture work?
- When a customer submits an estimate, their name, phone, suburb and job value are sent instantly to your email and the Leadkit dashboard, with a branded PDF attached. A hot / warm / cold score lets you prioritise which leads to call first.
- Can I brand the trades calculator for my business?
- Yes — upload your logo, set your accent colour, add your ABN and contact details. The calculator looks like part of your website and sends fully branded estimate PDFs to customers with your business details and ABN on every document.
- Are the calculators accurate for Australian pricing?
- Formulas are reviewed against current Australian trades material costs and labour rates, with defaults reflecting national averages. You can override any rate to match your local market, supplier prices and minimum job fee.
- Do I need to know how to code?
- No. Copy one embed snippet from your Leadkit dashboard and paste it into any website builder — WordPress, Webflow, Squarespace, Wix, Shopify or a custom-built site all work. No website? Every account gets a free auto-generated quote page at leadkit.com.au/quote/your-business.
- What if a trades calculator I need is missing?
- Use the request form below. Approved requests typically go live within days; we prioritise the ones with the most votes from the Leadkit community. Building a new trades calculator is free — there's no charge to request one.
