If you buy something for £100, what do you have to sell it for to make a gross profit margin of 33%? The answer is, of course, £150. Certainly every reader of Auto Retail Network’s Bulletin where this article was first published, would have got this simple example of ‘mark-ups and margins’ correct. However, our experience running training courses for sales executives and aftersales personnel is that the mathematical skills of dealer staff are often sadly lacking, and many would come up with £133 as the answer – how would yours fare? Furthermore, our research on gross margins strongly suggests that this lack of knowledge has an impact on profits.

For example, a few years ago we carried out a series of site visits for a dealer group client looking specifically at gross margins in their service departments, and with their permission, we can share one of the findings. The group’s minimum margin for sublet and sundry sales was fifteen per cent. But the actual average across all the sites we visited was just over fourteen per cent. On closer inspection, we found the majority of sites just added 15% to the cost price of sublet and sundry sales, which is a margin of 13%. To achieve a minimum 15% margin they should have added 17.6% to the cost price.

In this case, the difference in gross profit between a 13% and 15% margin is around £2,000 per annum for the average service department, because sublet and sundry sales only make up eight per cent of sales. However this group’s minimum margin on sublet and sundry was too low anyway – between 17.5% and 21.5% is average. At this higher level, more than £3,000 potential profit is lost because of the wrong mark-up.

We have seen similar instances of incorrect mark-ups that cause far larger losses in potential profit in sales, service, bodyshop, and parts. We have also seen evidence that ignorance of this relatively simple maths can affect the ability to negotiate good deals with suppliers and customers.

In the body repair market,for instance, bodyshops invariably have an inflated idea of their margins on refinish paint. When you research the specific question of paint margins, the results usually range from thirty-five to forty-five per cent. Yet the average gross profit margin achieved on paint is a fraction over 30%. In fact body repairers are probably quoting the discount they get from their suppliers – their so called ‘buying discount’. They are not taking into account discounts they give to work providers and customers, the vagaries of computer estimating systems, or any wastage (which can be huge for the more careless).

Going back to the dealer group case study, the upshot of the gross margins audit was a five-hour training course on mark-ups and margins. This extended to all departments across the group, and individual courses included a mixture of departmental delegates. A further audit after twelve months revealed a big improvement, with some of the best results coming from accessory sales through the showroom. Getting the basics right can make all the difference.
