Wages Percentage: What It Is, What It Should Be, and What to Do When It's Wrong.
Most service business owners know wages are their biggest cost. Almost none of them know what percentage of revenue that cost represents — or whether that percentage is sustainable.
Wages percentage is the single most important number in a service business. Not revenue. Not net profit. Not the number of clients. Wages percentage — the proportion of every dollar earned that goes to staff — is the metric that determines whether the business is structurally viable or whether it's generating activity without generating margin.
A business with a wages percentage of 30% has room to cover fixed costs, pay the owner properly, and still have something left over. A business with a wages percentage of 52% is working extremely hard, keeping its staff employed, and leaving almost nothing for the owner or the business itself. Both businesses might report similar revenue. Only one is actually working.
How to calculate it
Annual wages bill ÷ annual revenue × 100.
The wages bill includes all wages paid to staff — casual, part-time, full-time. It does not include the owner's drawings, unless the owner has a formal wage set at a market rate. If the owner works in the business and isn't paying themselves a wage, the true wages percentage is higher than the number suggests — because the owner's labour has a cost even if it's not yet reflected in the books.
Example calculation
What the benchmark is
For most service businesses in Australia and New Zealand, the target range is 28–38%. This isn't an arbitrary number — it's the range at which a business can cover fixed costs, pay a market-rate salary to the owner, and still have margin left over to reinvest or build a buffer.
Below 28%
Unusual for a service business unless it's highly automated or heavily owner-operated. Check whether all labour costs are captured.
28–38%
Target range. The business has room to cover fixed costs and still generate margin. Not comfortable, but viable and compounding.
38–45%
Warning zone. The business is generating revenue but the margin is thin. One slow month or one unexpected cost is felt immediately. Review pricing and roster.
Above 45%
Unsustainable without structural change. The business is generating activity but not generating a viable return. This is the number that looks like a revenue problem but is almost always a pricing or staffing structure problem.
“Wages percentage is the number that determines whether the business compounds or treads water. Most owners discover they've been treading water for years when they finally calculate it.”
Why it gets too high
Wages percentage gets too high for three reasons: revenue is too low, staffing hours are too high relative to the revenue those hours produce, or — most commonly — both at once. The hardest situation to diagnose is when both are true, because fixing one without the other doesn't move the number far enough to matter.
A business with underpriced services and more staff than the revenue can support will have a high wages percentage regardless of how efficiently the roster is managed. The efficiency gain from tightening the roster is wiped out by the pricing gap. Conversely, a business that raises prices but doesn't review the staffing structure may improve margin on paper while still carrying hours the business doesn't need.
How to fix it — the right order of operations
Don't start by cutting wages. That's not the diagnosis — it's a response to a symptom. Start by identifying which lever is actually out of alignment.
If transaction value is the issue — the average job or appointment isn't generating enough — the answer is pricing. Fix pricing before touching the roster. A correctly priced service business with a tight roster is structurally sound. The same roster with the same hours but underpriced services will never reach the target percentage no matter how efficiently it's managed.
If pricing is already right and the percentage is still too high, the issue is hours — usually a roster that hasn't been reviewed against actual revenue production. Not all hours are equal. A four-hour morning shift in a hair salon generates different revenue than a four-hour afternoon shift. A roster built around availability rather than production will carry the wrong hours.
The correct sequence: set pricing correctly. Then assess what staffing level that pricing can sustainably support. The wages percentage target tells you what that level is.
