How to Improve Your Workshop’s Labour Gross Profit

There are only three levers for improving your workshop’s labour gross profit: your labour rate, your technician cost per hour, and your billable hours. If your LGP is below 60%, at least one of these is out of alignment — and pulling all three simultaneously produces results that significantly outpace working any single lever alone.

There are only three levers for improving your workshop’s labour gross profit: your labour rate, your technician cost per hour, and your billable hours. If your LGP is below 60%, at least one of these is out of alignment — and pulling all three simultaneously produces results that significantly outpace working any single lever alone.

If your Labour Gross Profit (LGP) is below 60%, there are only three levers to pull — and most workshops are not pulling all of them.

LGP is the percentage of your labour revenue left after paying your technicians’ wages and superannuation. Below 60% means more than 40 cents in every labour dollar you bill is going straight to wage costs before any overhead has been paid. It is a margin that makes it very difficult to run a profitable, sustainable business.

Lever 1: Review Your Labour Rate

The most common cause of a low LGP is a labour rate that has not kept pace with wage increases. Wages move every year — through award adjustments, market pressure, and the cost of keeping good people. Labour rates, in many workshops, go two or three years between reviews. The gap grows silently.

A $10/hr rate increase sounds significant. The maths tends to change that perception quickly.

Three technicians billing 35 hours per week at a $10/hr rate increase generates an extra $54,600 in revenue per year — all of it flowing directly to gross profit, because your wage costs have not changed. The same increase on five technicians produces $91,000 in additional annual profit.

When reviewing your rate, consider:

• When you last reviewed it — if it was more than 12 months ago, it is almost certainly overdue
• What your local market is charging — call three workshops in your area and ask for a quote on a standard service
• What your costs have done — wages, rent, insurance, and parts costs all move upward; your rate should track accordingly
• Whether you are discounting in practice — a $180/hr posted rate that is regularly discounted to $160 is effectively a $160/hr business

A note on price sensitivity Workshop owners frequently overestimate the resistance customers will have to a rate increase. Research consistently shows that customers are far more sensitive to communication quality, wait times, and trust than to a $10–$15 difference in hourly rate. If you are delivering a professional, reliable service, your rate should reflect that.

Lever 2: Reduce Tech Cost Per Hour

Your tech cost per hour is their annual salary plus superannuation, divided by approximately 1,800 productive hours per year. A technician on $65,000 including super costs roughly $36/hr. That is the number that matters for LGP — not their hourly pay rate on paper.

There are several ways this number creeps higher than it should:

Overtime. A technician paid time-and-a-half for three hours on a Saturday is not costing you 1.5× their hourly rate — they are costing you significantly more when you factor in the unproductive hours baked into their weekly cost. Minimising unnecessary overtime tightens cost without changing the rate.

Rostering efficiency. If you are rostering four technicians for a week where you have three technicians’ worth of work, you are paying for capacity that is not generating revenue. Better job scheduling and forward booking visibility reduces this.

Superannuation increases. The super guarantee has increased incrementally over recent years. Each increase lifts tech cost per hour. If you have not reviewed your LGP since the last super increase, your margin is lower than you think.

The goal is not to reduce your technicians’ wages — it is to make sure you are billing enough to justify the cost, and that you are not carrying wage expense that is not matched by billable work.

Lever 3: Increase Billable Hours

Every hour your technicians clock but do not bill is a double cost: you are paying for their time, and you are not generating revenue from it. The gap between clocked hours and billed hours is one of the most common — and most recoverable — sources of lost profit in a workshop.

Common causes of unbilled time include:

• Warranty and goodwill work that is completed but not properly tracked or documented
• Internal work — servicing courtesy vehicles, workshop equipment maintenance — that is not allocated to a job card
• Time between jobs — waiting for parts, setting up equipment, general downtime that accumulates invisibly across the day
• Comebacks — rework on a previous job that absorbs technician time without generating a charge

The compounding effect Pulling all three levers at once is where the real impact is felt. A $10/hr rate increase combined with recovering two extra billable hours per technician per week, across a team of three at current tech costs, can add $80,00∓$100,000 in annual profit. Neither change alone gets close to that number.

The What If Calculation

Before committing to changes, it helps to model the impact. The Workshop University Labour Gross Profit Calculator includes a What If section that lets you adjust rate, cost, and hours with a slider to see the effect on your weekly, monthly, and annual numbers in real time. It takes less than two minutes to understand what each lever is worth to your specific business.

Three Things to Do This Week

• Check your current LGP using the calculator — if you do not know the number, you cannot manage it.
• Put a rate review in the diary — gather three competitor quotes and calculate what a $10/hr increase would add to your annual profit.
• Track your billable vs clocked hours for one week — pull last week’s figures from your workshop management system and calculate the ratio.

How often should I review my workshopb��s labour rate? At minimum, annually — and ideally in line with your main wage review. Because wage costs increase each year through award adjustments and super increases, a rate that is not reviewed erodes your LGP gradually. Many workshop owners find their rate has fallen 15–20% below the market after two years without a review.

What is a reasonable technician cost per hour? Technician cost per hour is annual salary plus superannuation divided by approximately 1,800 productive hours per year. A technician earning $60,000 plus 11.5% super ($6,900) has a total cost of $66,900, giving an hourly cost of approximately $37/hr. Higher base wages, frequent overtime, or rostering inefficiency push this number up.

How do billable hours affect labour gross profit? Every additional billable hour per technician per week generates revenue equal to your labour rate with no increase in wage costs — making it pure gross profit addition. Conversely, clocked hours that are not billed represent a double cost: wages are paid, but no revenue is generated. A workshop running at 70% efficiency (rather than 80%) is effectively paying for 10% of technician time with zero return.

What is the fastest way to improve LGP if I cannot raise my rate? Focus on billable hours. Review your current efficiency rate (billed ÷ clocked hours), identify the primary sources of unbilled time (warranty, internal work, job gaps), and implement a strict job card policy — every piece of work that touches a technician’s hands should be on a job card. This is typically the fastest improvement available without any external price change. The Technician Efficiency Calculator can help you quantify the opportunity.

Frequently Asked Questions

What are the three main ways to improve labour gross profit in a workshop?

The three levers are: increasing your labour rate, reducing your technician cost per hour, and increasing the number of billable hours per technician per week. Your labour rate is usually the highest-return lever — a rate increase flows almost entirely to profit because wage costs are unchanged. Improving billable hours is often the fastest win if your efficiency rate is below 75%.
