How to Price Builder's Jobs in Australia (2026 Guide)

What Are Builders Charging in Australia in 2026?

Builder rates vary significantly depending on the type of work, the state, and whether you're quoting a day rate or a fixed-price contract. Here's a general snapshot:

These are charge-out rates — not take-home pay. The difference between what you charge and what you actually keep is where most builders lose money.

Why Most Builders Are Underpriced

The most common pricing mistake builders make is basing their rate on what competitors charge, what they've always charged, or what they think clients will accept — rather than what their business actually needs to generate.

The result: a full order book, long hours, and not enough money at the end of the month.

The solution is to build your rate from the ground up using real numbers.

Step 1: Calculate Your Actual Billable Days Per Year

You don't earn money every day you go to work. Start by calculating how many days you can actually bill for.

Starting point: 52 weeks × 5 days = 260 potential working days

Subtract non-billable time: - Annual leave: 20 days - Public holidays: 10–12 days - Wet weather and site delays: 10–20 days - Quoting, tendering, admin: 20–30 days - Sick leave: 5–10 days

Realistic billable days for a sole trader builder: 170–200 days per year

Many builders assume they'll bill 200+ days a year and find they're actually billing closer to 160. That gap destroys your pricing model if you don't account for it.

Step 2: Calculate Your Annual Operating Costs

Pull your actual figures from your accounting software or bank statements. Don't estimate — get real numbers.

Costs to include: - Vehicle: repayments, registration, insurance, fuel, servicing - Tools and plant equipment (purchase, depreciation, replacement, hire) - Builder's licence and insurance (public liability, professional indemnity, workers' comp) - Phone, internet, software subscriptions - Accounting, bookkeeping, legal - Marketing, website, signage - Protective equipment and workwear - Training and licencing requirements - QBCC/VBA/BSB levy and registration fees

A realistic annual overhead for a sole trader builder: $70,000 – $120,000+

This feels high until you actually add it up — and then it makes complete sense.

Step 3: Set a Target Wage

Don't treat your wage as whatever's left over. Set it as a fixed cost, the same as your van repayment.

Market rates for builders in employment: - Qualified carpenter/builder (3–5 yrs): $85,000 – $105,000 - Experienced builder / site manager: $100,000 – $130,000 - Licensed builder / project manager: $120,000 – $160,000+

As a business owner, you take on risk that an employee doesn't — so your wage should be at the higher end of these ranges, or above them.

Step 4: Calculate Your Break-Even Day Rate

Formula:

Example: - Annual overheads: $90,000 - Desired wage: $110,000 - Total needed: $200,000 - Billable days: 180

$200,000 ÷ 180 = $1,111/day just to break even

Add a 15–20% profit margin and your day rate should be closer to $1,280–$1,335/day to run a truly healthy business.

If you're currently charging $800/day, the numbers make the problem clear.

Step 5: How to Price a Building Project (Not Just a Day Rate)

For most building work, you'll be quoting fixed-price contracts rather than working on a day rate. Here's how to build an accurate project quote:

Labour Estimate the total days required for each trade stage. Be honest — include site setup, cleanup, waiting time for inspections, and rework allowance (budget 5–10% for variations and minor rework on most residential jobs).

Multiply by your day rate.

Materials Get supplier quotes where possible — don't estimate from memory. Apply a materials markup of 15–25% to cover your time ordering, collecting, and managing materials.

Subcontractors Get written quotes from your subbies and add a margin of 10–15% for coordination and risk.

Preliminaries and site costs Include skip bin hire, scaffold hire, temporary fencing, site toilets, traffic management, or any other site-specific costs.

Contingency Add 10–15% on residential renovations and 5–10% on new builds. Renovations always hold surprises.

Project management If you're spending significant time managing a project (attending meetings, coordinating trades, doing variations admin), price that time separately. Many builders forget to charge for this — and it can add up to weeks of work on a large renovation.

Typical Price Ranges for Common Building Jobs (2026)

These are indicative ranges. Costs vary significantly based on specification, site conditions, and location.

Fixed Price vs. Cost Plus: Which Model Is Right for You?

Fixed price gives clients certainty but puts the risk on you. Works well when scope is clearly defined and you've done similar work before. Requires disciplined quoting and a solid variations process.

Cost plus (you charge actual costs plus a margin) gives you more protection when scope is unclear. Works well for renovations with unknowns, or clients who want to make decisions as the build progresses. Can be harder to win against fixed-price competitors.

Most experienced builders use fixed price for well-defined projects and cost plus (or a hybrid) for complex renovations or extensions where the scope can shift.

How to Handle Variations Without Losing Money

Variations are where builder profit goes to die — if you're not managing them properly.

Every time scope changes, you need a written variation approved by the client before the work is done. Not after. Not verbally. In writing.

A simple variation process: 1. Identify the change in scope 2. Estimate the additional cost (labour + materials + margin) 3. Send a written variation quote with a description of the change 4. Get written approval (email is fine) before proceeding 5. Invoice the variation separately or add it to the final invoice with a clear line item

Builders who skip this step end up absorbing thousands of dollars in unrecovered variations on every major project.

How to Track Whether Your Pricing Is Working

If you're not tracking job profitability, you have no idea whether your pricing is actually working. A job that looks profitable on paper can quietly lose money through extra hours, unrecovered materials, and unbilled variations.

Job management software like TradeTrack lets you track actual vs. estimated hours, costs, and revenue on every project — so you can see exactly where your margin is going and tighten your quoting over time.

Key Takeaways

• ✓Most builders are undercharging because they've never properly calculated their operating costs
• ✓Your break-even day rate is almost certainly higher than you think
• ✓Fixed-price contracts need a solid variations process or your margin disappears
• ✓Track actual job costs against estimates so your quoting improves over time
• ✓Profit isn't what's left over — it should be built into your price from the start

Get your pricing right and everything else in your business gets easier.
