A profitable quote is built from four parts: labour, materials plus markup, travel or callout, and — if you are registered for GST — 10% GST on top. Getting any one of these wrong is the fastest way to quote a job that loses you money, so it pays to build every quote the same way.
The plain-text formula this calculator uses is:
Say you quote an 8-hour job at a $100/hr charge-out rate, with $400 of materials marked up 20%, and a $60 callout fee. Labour is 8 × $100 = $800. Materials become $400 + ($400 × 20%) = $480. The subtotal is $800 + $480 + $60 = $1,340. Adding 10% GST ($134) gives a total quote of $1,474. If you weren't registered for GST, the quote would simply be the $1,340 subtotal.
The single biggest pricing mistake is setting a charge-out rate close to what you'd earn as an employee. Your rate has to cover the hours you can't bill (quoting, travel, admin, chasing payment), plus tools, vehicle, fuel, insurance, licences, super and a profit margin. Most sole-trader tradies in Australia charge between $80 and $150 an hour, with licensed and specialised trades charging more.
Charging materials at cost gives away the time and risk of sourcing them. A markup of 10–30% on your cost price covers collection, handling, delivery, warranty and the cash-flow gap between paying your supplier and getting paid by the customer.
You must register for GST once your turnover reaches $75,000 in any rolling 12-month period, after which every taxable quote should be GST-inclusive (10% on the subtotal). Below that threshold you can stay unregistered and quote without GST — switch the GST toggle off in the calculator above. Either way, once a job is over $82.50 you must give the customer a valid tax invoice, which you can create with the free invoice generator.
Once you're happy with the price, send a clear written quote that states exactly what is and isn't included. See the tradie quoting guide for templates and tips, learn how OneBookPlus helps tradies quote, schedule and invoice, or check the GST maths with the GST calculator.
Build a quote from the ground up: (1) estimate the labour hours and multiply by your charge-out rate, (2) add the cost of materials plus a markup to cover sourcing, handling and risk, (3) add any callout or travel fee, and (4) if you are registered for GST, add 10% GST to the subtotal. The total is the price you quote the customer. This calculator does all four steps for you.
Charge-out rates vary by trade, location and experience, but most Australian sole-trader tradies charge somewhere between $80 and $150 per hour, while specialised or licensed work (electrical, plumbing, HVAC) often runs $100 to $180+ per hour. Your charge-out rate is not your wage — it must also cover tools, vehicle, insurance, super, downtime, admin and profit. Work backwards from the annual income you need plus overheads, divided by your realistically billable hours.
A materials markup of 10% to 30% is standard for Australian trades. The markup compensates you for sourcing, collecting, storing, delivering and warranting the materials, plus the cash-flow cost of paying suppliers before the customer pays you. For large material-heavy jobs many tradies use a lower percentage (10%–15%); for small jobs with lots of small parts a higher markup (25%–30%) is common. Markup is calculated on your cost price, not the sell price.
If your business is registered for GST you must add 10% GST to the price of your taxable sales, so your quote should be GST-inclusive. You are required to register for GST once your turnover reaches $75,000 in a rolling 12-month period. If you are not registered for GST (turnover under $75,000 and not voluntarily registered) you do not charge GST — turn the GST toggle off.
A fixed-price (lump-sum) quote gives the customer certainty and rewards you for working efficiently, but you carry the risk if the job runs over. Charging by the hour (a 'do-and-charge' or time-and-materials job) protects you on jobs with unknown scope. Many tradies quote a fixed price for well-defined work and use hourly rates for diagnostics, variations or jobs where the scope can't be pinned down. Use this calculator to sanity-check either approach.
A quote is a fixed, binding price for clearly defined work — once accepted, you are generally committed to that figure unless the scope changes. An estimate is your best-guess approximation that can move as the job unfolds. Always put quotes in writing, state exactly what is and isn't included, and note that the price may change if the customer requests variations or hidden issues are uncovered.
Sources & methodology
This tradie quote calculator builds your price the way trades professionals do: labour (your charge-out rate × estimated hours), plus materials at cost with a percentage markup, plus any travel or callout fee. That gives a subtotal, and — if you're registered for GST — Australia's flat 10% GST is added on top to give the final quote. Everything is computed in your browser; nothing you enter is stored or sent to a server.
