If you run a labour hire agency, chances are you believe your margins are healthier than they really are.
In fact, most labour hire agency owners think they’re operating at around an 18% margin. Based on BYN Accounting’s analysis of early childhood labour hire businesses across Australia, the reality is usually closer to 8–12%.
That gap isn’t bad luck or poor management; it’s what we call phantom profit. Money that looks real on paper but doesn’t exist once all costs are properly accounted for.
This article explains what true margin actually is, how to calculate it correctly, and why it’s one of the most important numbers in a sustainable labour hire business.
True margin is the actual profit you make per billable hour after accounting for all employment-related costs, not just the hourly rate you pay your workers.
Most agencies calculate margin using only bill rate and pay rate. That approach ignores statutory obligations, leave provisions, recruitment costs, and compliance expenses that quietly erode profitability over time.
True margin answers one simple question:
“After everything this worker costs me, how much do I really make per hour?”
Gross margin is usually calculated like this:
Bill Rate minus Pay Rate, divided by Bill Rate.
For example:
That gives a gross margin of 28.9%, which looks healthy on the surface.
The problem is that this figure excludes a long list of real costs that don’t disappear just because they’re not on the payslip.
True margin uses true cost per hour, not just the base pay rate.
True cost per hour includes:
Only after including all of these can you see what margin you’re actually running.
Let’s look at a realistic example for an early childhood educator paid $32 per hour.
When all costs are included, the true hourly cost looks like this:
True cost per hour: $42.76
Now, using the same $45 bill rate:
True margin = ($45.00 − $42.76) ÷ $45.00
True margin = 4.98%
In this example:
That difference — nearly 24% — is phantom profit.
On an agency turning over $2.8 million per year, that miscalculation can represent hundreds of thousands of dollars the owner believes they’re making, but aren’t.
This is why labour-hire businesses can appear profitable while struggling to pay tax, wages, or suppliers.
Based on BYN Accounting’s work with early childhood labour hire businesses with a turnover between $2M and $10M turnover, the following benchmarks apply:
As a rule of thumb, well-run labour hire agencies should target at least a 12% true margin.
Award wages typically rise faster than client fees. If you haven’t reviewed client rates in the past 12 months, your margins have already shrunk.
Superannuation increases, WorkCover adjustments, payroll tax thresholds, and leave accruals all compound quietly in the background.
With a national shortage of qualified educators, recruitment costs are rising sharply. When you factor in advertising, onboarding, training, lost productivity, and bad-hire risk, replacing a single worker can cost tens of thousands of dollars.
Racing competitors to the bottom on rates always ends the same way. If someone is charging rates below sustainable levels, they’re either miscalculating, cutting compliance corners, or heading for failure.
A quick margin health check is the bill-to-pay ratio:
Bill Rate ÷ Pay Rate
As a guide:
For early childhood labour hire, a minimum target of 1.35:1 is recommended.
There are only three real levers.
Review contracts, benchmark market rates, and be prepared to have difficult conversations. Losing unprofitable clients is often healthier than keeping them.
Improve retention, reduce recruitment churn, manage WorkCover claims proactively, and improve utilisation so fixed costs are spread across more billable hours.
If educators are available but not placed, the margin deteriorates rapidly. Aim for utilisation of 85% or higher wherever possible.
In some cases, the right decision is to exit clients who consistently operate below a sustainable margin.
At a minimum, labour hire agencies should review the following each month:
These reviews prevent margin erosion from becoming a surprise.
True margin is not the same as gross margin.
Most labour-hire agencies believe they’re making around 18%, whereas the reality is closer to 8–12%. That misunderstanding is one of the biggest reasons otherwise “successful” agencies struggle with cash flow and sustainability.
If you don’t know your true cost per hour, you don’t know your margin — and if you don’t know your margin, you don’t really know your business.
