Most clinics hire when they feel busy. Feeling busy is not the same as being full, and the difference between the two is a year of paying somebody out of a diary that was never as tight as it seemed.
The decision has an arithmetic, and it is not complicated. What makes it hard is that two of the four numbers are ones most clinics have never worked out.
First: are you actually full?
Before any of the money, answer this. Two figures settle it, and they have to be read together.
- Utilisation — the share of sellable hours that were booked. Per clinician, not averaged across the practice; one person at 95% and one at 45% averages to a healthy-looking 70% and describes neither.
- Time to third available appointment — how many days until the third free slot, which is what a patient calling today actually waits.
| Utilisation | Wait | What it means |
|---|---|---|
| High | Long | Genuinely full. This is the case a hire fixes. |
| Moderate | Long | A scheduling problem. A second clinician inherits it. |
| High | Short | Efficient, and demand is the constraint. Hiring adds cost, not income. |
| Low | Short | Not busy. The feeling was volume of interruption, not volume of work. |
Only the first row is a hiring signal. The second is the expensive mistake: a diary with structural holes does not fill because somebody new is standing in it, and now the holes cost a salary. The measurements themselves are worth getting right before this decision, not during it.
What the hire costs — all of it
Salary is the number people plan with and it is usually about two-thirds of the real one. The rest arrives quietly.
- Employment costs on top of salary — contributions, insurance, leave, whatever your country adds. This varies enormously and it is not optional.
- Their share of the room. If the new person needs a chair or a room that is not currently idle, you are buying capacity as well as labour.
- Consumables and lab work at their volume, which scales with them rather than staying fixed.
- Your time. Somebody now supervises, reviews and covers for them. That time comes out of your own clinical hours, and it is the cost owners never enter.
What they can bring in — after the ramp
Nobody is full from month one. A new clinician arrives without a patient list, and unless you are handing them yours, they build one at the speed your enquiries arrive.
Budgeting for a full diary in month one is the single most common error in this decision. Six months to reasonable occupancy is a normal shape, and it is six months of paying somebody in full.
Example
A worked example — your own numbers will differ
- Cost per sellable hour of the clinic: 144
- New clinician, 130 sellable hours a month
- Fully loaded cost: 6,200 a month
- Revenue per hour they can realistically bill: 95
- At 100% occupancy: 12,350 — comfortable
- At 45% in month two: 5,558 — a loss
- Break-even occupancy: 6,200 ÷ (130 × 95) = 50%
That last line is the number to carry into the decision. Not "can they pay for themselves at capacity" — everybody can. The question is what occupancy they need to stop costing you money, and how many months you can fund below it.
The cost-per-hour half of this is worth computing properly rather than estimating, and there is a calculator for it that takes about five minutes.
Four things to try first
Each of these adds capacity or revenue without adding a salary, and each is reversible in a way a hire is not.
- Recover the capacity you already lose. If missed appointments are running at any meaningful rate, that is capacity you are paying for and not selling — cheaper to reclaim than to buy more.
- Fix the shape of the diary. Slots sized by service rather than a uniform default, and blocked time that reflects reality, frequently release hours nobody knew were there.
- Change the mix, not the volume. Some work earns more per hour than other work. Knowing which is a pricing question and it can move revenue without moving anybody's hours.
- Extend hours before extending headcount. An evening or a Saturday morning tests whether the demand is real, at a cost you can stop next month.
If all four are exhausted and the wait is still long, that is the point at which the hire is the answer rather than the reflex.
Employee, or self-employed?
The structure changes the arithmetic entirely, and which structures are lawful for clinical staff differs by country — this is a question for your accountant rather than for a blog. What is generally true is the shape of the trade.
| You carry | They carry | |
|---|---|---|
| Employed | The fixed cost from day one, and the ramp | Less risk, and usually less upside |
| Percentage or room rental | Less downside during the ramp | The empty weeks |
The second is why associate and rental arrangements are common in exactly the specialities where ramps are long. It is also why they can end badly: the person carrying the empty weeks is the person who leaves when a better room appears.
A short checklist
- Measure utilisation per clinician and the wait to the third available appointment.
- Confirm you are in the full-and-waiting case, not the scheduling one.
- Compute cost per hour, then the fully loaded monthly cost of the hire.
- Work out break-even occupancy, and how many months below it you can fund.
- Try the four cheaper things, and give each of them a month.
- Decide the structure with your accountant, not from an article.
Most clinics that run this honestly find one of two answers: they were not as full as they felt, or they should have hired eight months ago. Both are useful, and neither is available from the feeling.
Common questions
- What utilisation rate means a clinic is ready to hire?
- There is no threshold worth borrowing, because it depends on how much slack your work needs and how long your appointments run. What generally holds: below about 60% you are already paying for time you are not selling, and above about 90% you have no room to absorb an overrun. Read it per clinician, and read it alongside how long a new patient waits — high utilisation with a short wait means demand is the constraint, and a hire does not fix that.
- How long before a new clinician pays for themselves?
- Plan for a ramp of several months rather than weeks, and budget the full cost throughout it. The specific number depends on how your enquiries arrive and whether you are handing over part of your own list. The useful figure is break-even occupancy — what share of their hours must be booked before they stop costing you — and how many months you can fund below it.
- Is it cheaper to extend opening hours instead?
- Usually, and it is reversible, which a hire is not. An evening or a weekend morning tests whether demand is real at a cost you can stop. If those hours fill and the wait stays long, you have evidence rather than a feeling.
- Should the first hire be a clinician or an administrator?
- It depends what is actually constraining you. If clinical hours are full and the wait is long, a clinician. If clinical hours have holes and the phone never stops, an administrator — or removing the phone traffic — releases clinical capacity you are already paying for. The two feel identical from inside a busy week and have opposite answers.
