Quote Price Calculator

Build a complete job quote from materials, labour, subcontractors and your markup percentage. Get the client price including and excluding GST instantly. Stop under-quoting.

Quick answer: Quote Price = (Materials + Labour + Subs) ร— (1 + Markup%) ร— (1 + GST%). A job costing $8,000 with 25% markup = $10,000 ex-GST = $11,000 inc-GST to the client.

๐Ÿ“ How It Works

A job quote adds your markup to the total direct costs to arrive at your selling price. GST is then added on top of the selling price. Markup is calculated on cost. The resulting profit margin (on selling price) will always be lower than the markup percentage.

Total Cost = Materials + Labour + Subs + Other Ex-GST Price = Total Cost ร— (1 + Markup%) Inc-GST Price = Ex-GST Price ร— (1 + GST%) Profit Margin = (Price โˆ’ Cost) รท Price ร— 100

๐Ÿ“‹ Worked Example

Tiling job: Materials $2,800, Labour $2,400, Other $200. Total = $5,400. At 25% markup: Ex-GST = $6,750. Profit = $1,350 (20% margin). Inc 10% GST = $7,425 to quote the client.

โ“ Frequently Asked Questions

Most contractors apply a single markup to total job cost. Some apply a higher markup to materials (to account for procurement effort) and lower to labour. Either approach works as long as the combined quote covers all costs and delivers your target margin.

15โ€“30% is typical for most trade contractors in Australia. Use the Hourly Rate Calculator first to determine your minimum charge rate, then work backward to find the markup that covers your overheads. Don't guess โ€” under-quoting is the most common reason trade businesses fail.

Always present the inc-GST price prominently to the client โ€” it's the total they pay. Show ex-GST as a separate line. For B2B clients who are GST-registered, show both clearly. For consumers, the inc-GST price is legally required to be the prominent price.

For jobs starting more than 4 weeks from quote date, add a material price escalation allowance (typically 5โ€“10%) or include a quote validity period of 14โ€“30 days. Major material prices (steel, timber, copper) can change rapidly โ€” protect yourself with a validity clause.
