Profitability: Understand Your Numbers and Keep More of What You Earn
Most workshops are busy. Not all of them are profitable. This page covers the numbers, strategies, and mindset shifts that help you keep more of what you work so hard to earn.
Check Your Workshop Health ScoreWhy Most Workshops Struggle With Profitability
Here is a scenario that might sound familiar. You are flat out every day. The workshop is booked. Your technicians are busy. Customers keep coming in. But at the end of the month, when you look at what is left in the account, it does not match the effort you put in.
Most workshop owners price their labour based on what competitors charge rather than what it actually costs them to deliver the work. The result is a labour rate that covers wages but leaves nothing for profit, overheads, or growth.
Then there is the work you do not bill for. The extra half hour on a job that ran over. The courtesy check you did not charge for. The come-back you absorbed. These small leaks add up to thousands of dollars every month.
And most owners do not track parts margin separately from labour margin, which means they have no idea where the profit actually comes from or where it is disappearing to.
The good news is that profitability is not about working harder. It is about understanding your numbers and making better decisions with the information you already have.

What You Need to Know About Profitability
1 Labour Gross Profit
Labour Gross Profit is the profit remaining after paying technician wages, expressed as a percentage of your total labour revenue. It is the single most important indicator of whether your pricing is healthy.
If you bill $40,000 in labour and pay $16,000 in technician wages (including super), your Labour Gross Profit is 60%. That means 60 cents of every labour dollar stays in the business to cover overheads, rent, equipment, and your own income.
Benchmark: Aim for 60-70% or higher. Below 55% means your labour pricing almost certainly needs a review. Many workshops we work with have improved this number by 10-15 points simply by recalculating their true cost per productive hour and adjusting their rate.
2 Effective Labour Rate
Your posted labour rate is what you charge. Your Effective Labour Rate is what you actually earn per hour of technician time. The gap between the two represents all the revenue that leaks out through unbilled work, discounting, under-quoting, and downtime.
If your posted rate is $180/hour but your effective rate is $130/hour, you have a $50/hour gap. Across three technicians working 40 hours a week, that gap represents $6,000 per week in lost revenue potential.
Practical tip: Audit one week of completed jobs. Compare the time quoted against the time actually spent. How many hours were given away? Multiply those hours by your posted rate. That is the revenue you left on the table in a single week.
3 Average Repair Order
Your Average Repair Order (ARO) is the total revenue divided by the number of completed jobs. Small increases in ARO have a massive compound effect. If you complete 40 jobs a week and increase your ARO by just $50, that is an extra $2,000 per week – over $100,000 per year.
The most effective way to increase ARO is not upselling. It is performing a thorough digital vehicle inspection on every job and presenting the findings to the customer with photos. Customers approve work they can see and trust.
Practical tip: Track your ARO monthly. The absolute number matters less than the trend. Is it going up, down, or flat? If it is flat, look at how consistently your team is performing inspections and presenting findings.
4 Parts Margin
Many workshop owners focus on labour revenue but overlook parts as a profit centre. The margin you make on parts – the difference between what you pay and what you charge – can significantly impact your overall profitability.
Practical tip: Establish a standard parts markup policy and apply it consistently. A tiered approach works well – higher percentage markup on low-cost items, moderate markup on mid-range, and lower percentage (but higher dollar) markup on expensive parts. Review your parts margin monthly alongside your labour margin.
5 Common Profit Leaks
Profit leaks are the small, recurring losses that individually seem minor but collectively drain thousands from your business every month. The most common ones we see across workshops are unbilled time, courtesy work, come-backs, and poor job costing.
Practical tip: Pick one of these leaks and focus on it for a month. Track it, measure it, and put a process in place to reduce it. Once you have plugged one leak, move to the next. Small changes compound quickly.
Three Things You Can Do This Week
Calculate Your Labour Gross Profit
Pull up last month’s total labour revenue and total technician wages including super. Divide the difference by revenue and multiply by 100. If it is below 60%, your pricing needs a review.
Audit One Week of Jobs for Unbilled Time
Look at every completed job from last week. Compare time quoted against time actually spent. Multiply the difference by your posted rate. That number is what you gave away in a single week.
Review Your Labour Rate Against Your Costs
Calculate what it actually costs per hour to have a technician available – wages, super, leave loading, training, downtime, and overheads. Compare that to your posted rate. Is the gap big enough to cover profit?

How to Get Profitable Fast
Most profit leaks hide in everyday jobs: prices that never moved, time that never got billed, discounts applied to the wrong parts. James Mitchell’s free book walks through 13 of them and how to fix each one. No email needed.
