Allied health is a service business. Revenue is generated by clinicians doing billable work, measured in hours, charged at an hourly rate. The maths is simple. The execution is not.
The sector benchmark sits at approximately 5 billable hours per clinician per day. At current NDIS rates, that generates around $193,000 to $215,000 per clinician per year depending on discipline. It sounds reasonable. But when you run the numbers through a proper P&L — wages, super, leave, insurance, rent, admin, software, compliance — the margin on 5 billable hours is thin. In many practices, it’s negative.
This article breaks down what your utilisation rate actually means for your gross margin, your tax position, and your practice’s value. It’s the analysis that most allied health business commentary skips.
The Billable Hours Maths — What Each Hour Is Worth
| Daily Billable Hours | Annual Revenue / Clinician (OT/SP at $193.99) | Annual Revenue / Clinician (Physio at $183.99) |
|---|---|---|
| 4.0 hours | $171,191 | $162,391 |
| 4.5 hours | $192,590 | $182,690 |
| 5.0 hours | $213,989 | $202,989 |
| 5.5 hours | $235,388 | $223,288 |
| 6.0 hours | $256,787 | $243,587 |
Based on 44 billable weeks per year (allowing for leave, public holidays, and seasonal dips).
The difference between 5 and 6 billable hours per day is approximately $43,000 per clinician per year. For a practice with 10 clinicians, that’s $430,000 in additional revenue — enough to fund 3-4 full-time admin staff, which would likely free up even more clinical capacity.
What Utilisation Means for Gross Margin
The gross margin impact of utilisation is where most practice owners get surprised. A clinician on a $90,000 base salary costs approximately $135,000 fully loaded (salary + super + WorkCover + leave loading + devices + CPD allowance). That’s the breakeven revenue they need to generate before contributing a single dollar to overhead.
- At 4 hours/day: $171,191 revenue − $135,000 cost = $36,191 gross contribution (21% margin)
- At 5 hours/day: $213,989 revenue − $135,000 cost = $78,989 gross contribution (37% margin)
- At 6 hours/day: $256,787 revenue − $135,000 cost = $121,787 gross contribution (47% margin)
The margin difference between a 4-hour and 6-hour clinician is 26 percentage points. That’s the difference between a practice that struggles to pay its rent and one that generates real profit for its owner.
The Tax Implications of Utilisation
Higher utilisation doesn’t just mean more revenue — it changes your tax position in ways that require active management.
Trust Distributions and Utilisation
Most allied health practices are structured as discretionary trusts. When utilisation increases, trust income increases, and the distribution strategy needs to be reviewed. A practice that was distributing $150,000 to the primary beneficiary may find itself with $250,000 to distribute as utilisation improves — pushing the owner into the 45% tax bracket if distributions aren’t structured correctly.
The solution is proactive distribution planning — identifying lower-tax beneficiaries (adult children, spouses, corporate beneficiaries) and structuring distributions before 30 June. This is the kind of planning that pays for itself many times over, but it requires visibility of your utilisation numbers well before year-end.
Superannuation Contributions and Utilisation
Higher utilisation means higher revenue, which creates more capacity for concessional superannuation contributions. The $30,000 annual concessional cap (2025-26) is one of the most tax-effective tools available to practice owners. If your utilisation has been low and your contributions have been minimal, you may be able to use the carry-forward provisions to make larger contributions in years when utilisation — and income — is higher.
What Utilisation Means for Practice Valuation
Utilisation is one of the most powerful levers for increasing practice value. Here’s why:
A practice with 10 clinicians at 5 hours/day generates approximately $2.14M in revenue. At a 20% EBITDA margin, that’s $428,000 EBITDA. At a 3× multiple, the practice is worth approximately $1.28M.
The same practice at 6 hours/day generates $2.57M in revenue. At the same 20% EBITDA margin, that’s $514,000 EBITDA. At a 3× multiple, the practice is worth approximately $1.54M.
One extra billable hour per clinician per day = $260,000 increase in practice value. No new clinicians. No new locations. No new services. Just better utilisation of the team you already have.
Why Utilisation Is Low — And What to Do About It
The most common reasons allied health practices run below 5 billable hours per clinician are structural, not motivational:
- Clinicians doing admin: Every hour a clinician spends on scheduling, invoicing, or chasing service agreements is $193.99 in forgone revenue. A part-time admin person at $35/hr pays for themselves many times over.
- Poor geographic scheduling: Clinicians driving across the city between appointments. This is an operational design failure, not a clinician failure.
- No commercial onboarding: New graduates are not taught to think about billable hours at university. If you don’t set clear expectations from day one, you won’t get the output you need.
- No KPI visibility: You can’t manage what you can’t measure. If clinicians don’t know their utilisation target or their current performance, they can’t improve.

Utilisation is a financial problem as much as an operational one. If your practice is running below 5 hours per clinician per day, the tax, cash flow, and valuation implications are significant.
