How to Calculate Your Traffic Control Charge-Out Rate

To calculate a traffic control charge-out rate, start with the award wage for the time band you are pricing, add on-costs such as super and workers compensation, divide by the share of paid hours you can actually bill, add overheads and equipment recovery per billable hour, then apply your target margin. Repeat it for nights, weekends and public holidays.

Most new operators set their rate by ringing around and pitching a few dollars under the competition. That works until the first award increase, the first big insurance renewal or the first month where half the shifts were four-hour minimums. This guide shows the method an operations manager uses instead, so you know exactly what each dollar of your rate is paying for.

Charge-out rate, wage and price: what you are actually calculating

Three numbers get mixed up constantly in traffic control:

• The wage is what you pay the controller per hour under the award or agreement that covers them, including any casual loading and penalty for that shift. Our guide to traffic controller salary explains how award pay is built.
• The cost per billable hour is everything it costs you to put one controller on a client's job for an hour you can invoice: wage, on-costs, unbillable time and a share of overheads.
• The charge-out rate is the cost per billable hour plus margin. It is what appears on the quote.

Clients commonly see indicative rates of about $70 to $100 or more per controller per hour, with higher rates at night, on weekends and public holidays. That range tells you where the market sits. It tells you nothing about whether your business makes money at a given point in it. Two operators charging the same rate can have very different results because their billable-hours ratios and overheads differ.

Step 1: Work out the labour cost per paid hour

Start with the minimum rate for the controller's classification and employment type in the relevant award or enterprise agreement, for the specific time band. Use the Fair Work Ombudsman Pay Calculator or the award itself; if you pay above award, use what you actually pay. Call this W.

Then add the costs that follow every hour of wages. Express them as a percentage of W so the model updates automatically when wages change.

In this example only, the on-costs add 22% for a casual, so labour cost per paid hour is W × 1.22. A permanent worker's loading looks different: no casual loading in W, but paid leave and public holidays to recover.

Separate rates for each time band

Do not build one rate and add a flat percentage for nights. Penalty rates, overtime and minimum engagements in the award change W for each band, and some on-costs move with them. Build the calculation for weekday day shifts, nights, Saturdays, Sundays and public holidays separately. Public holidays in particular deserve their own line, because the award cost and the difficulty of filling those shifts are both higher.

Step 2: Convert paid hours into billable hours

This is the step that sinks traffic control companies. You pay for hours you cannot invoice:

• Induction, toolbox talks and training days, including refresher training for NSW workers who have not done traffic control work for two years (check current rules with SafeWork NSW).
• Travel time your award requires you to pay but your quote did not recover.
• The gap between an award minimum engagement and a client minimum that is shorter, or not enforced.
• Standby when a client is late and you have no standby clause.
• Shifts cancelled inside your notice period that you still pay but write off to keep the client happy.
• Disputed docket hours you credit back.

Pull a few months of payroll hours and invoiced hours and calculate the billable-hours ratio: invoiced controller hours divided by paid controller hours. If you have no history yet, make a conservative assumption and correct it after a quarter.

Example only: if you invoice 85 hours for every 100 you pay, labour cost per billable hour is W × 1.22 ÷ 0.85, or about W × 1.44. In other words, an unbillable 15% does not add 15% to your cost; it adds more, because you are spreading a fixed cost over fewer hours. Tight digital dockets and enforced minimum shift charges are the quickest ways to move this ratio.

Step 3: Add overheads per billable hour

Overheads are everything the business spends that is not tied to one job:

• Office and operations wages: allocators, schedulers, payroll, accounts, a safety coordinator.
• Insurance: public liability, professional indemnity if you design plans, motor and equipment cover.
• Software, phones, radios, rent, utilities and depot costs.
• Accounting, legal, prequalification, audits and certification.
• Marketing, tendering and bad debts.
• Your own salary if you work in the business. Leaving it out is the classic owner-operator mistake.

Add up a year of overheads and divide by the billable controller hours you expect in that year.

Example only: $300,000 of overheads over 20,000 billable controller hours is $15 per billable hour. If you only achieve 15,000 billable hours, the same overheads cost $20 per hour. That is why a quiet month hurts so much: the overhead does not shrink with the work.

Step 4: Decide how vehicles and equipment are recovered

You have two choices, and both are legitimate if you are consistent.

Bundle the standard kit into the controller rate. A ute, signs, cones and stands for a typical set-up are included. Work out the annual cost of the standard fleet (ownership, rego, insurance, fuel, maintenance, replacement of damaged signs) and divide by billable controller hours. This keeps quotes simple for small jobs.

Charge vehicles and plant separately. The ute or truck has its own rate and minimum, often 6 to 8 hours, and specialist plant such as truck-mounted attenuators, VMS boards and arrow boards is priced per shift or day. This is more accurate when your jobs vary a lot.

Either way, price TMAs on their own. Their capital cost, certification, operator licensing and utilisation are completely different from a ute. Our guide to hiring versus buying equipment helps you decide what belongs on your balance sheet.

Step 5: Apply margin correctly and set the final rate

Now add profit. Use margin, not markup, and know the difference.

The margin you need depends on the risk you carry, your growth plans, how much cash you need to fund wages before clients pay and what your accountant advises. Nobody can tell you the right percentage from a blog. What you can do is make it a deliberate choice rather than whatever is left after you match a competitor.

Putting the example together

Example only, for one time band:

1. Labour per billable hour: W × 1.44.
2. Overheads: plus $15.
3. Bundled standard kit: plus $6 (from your own fleet costs).
4. Cost per billable hour: (W × 1.44) + $21.
5. Charge-out rate at a 15% target margin: cost ÷ 0.85.

Plug in W for weekday days, then repeat with W for nights, Saturdays, Sundays and public holidays. Round to clean numbers, then sense-check against the market. If your weekday rate lands well above what clients are paying, look hard at the billable-hours ratio and overheads before you cut margin.

TrafWise has a free charge-out rate builder that walks through the same steps, so you can test different ratios and margins quickly.

Test the rate against minimums, travel and real jobs

A rate is only as good as the terms around it. Before you publish a rate card, check:

• Minimum charge. If the award makes you pay a minimum engagement, your client minimum must at least cover it. Four hours per controller is common.
• Travel. Decide whether travel is charged from the depot or a set radius, and make sure paid travel time is recovered somewhere.
• Overtime blocks. Time beyond the booked shift is often charged in half-hour or hourly blocks. Your award overtime cost may be higher than the rate you charge for extensions.
• Cancellation and standby. Without clear notice periods and standby charges, Step 2's ratio falls apart.
• Short-notice work. Same-day call-outs may carry award costs you are not recovering.

Then run your last 20 or 30 jobs through the model. Compare what each job should have earned at the new rate with what it actually cost in payroll and equipment. Jobs that consistently lose money tell you more than any benchmark. Our article on how to compare hourly and fixed-price pricing helps when a client asks for a lump sum instead.

Common charge-out rate mistakes

• Pricing from a competitor's rate. You do not know their costs, their award arrangements or whether they are making money.
• One rate for every time band. Night and weekend rates built as "day rate plus a bit" often lose money on exactly the shifts that are hardest to fill.
• Forgetting the owner's wage. If the business only works because you do 60 unpaid hours a week, it is not profitable yet.
• Ignoring unbillable time. Induction days, refresher training and travel add up quickly across a casual workforce.
• Applying markup when you meant margin. It shaves a few points off every quote.
• Never reviewing it. Award rates change through the Fair Work Commission's annual review, and insurance renews every year. A rate set two years ago is probably wrong.

Next steps

Pull your payroll and invoice data, calculate your billable-hours ratio, and build the rate one time band at a time. Then hold the rate with clear minimums and clean dockets. If your docket and payroll data are scattered across paper and spreadsheets, TrafWise keeps shift times, signed dockets and rosters in one place so the numbers in this model are real rather than guessed.
