As an automotive repair business owner, setting and hitting appropriate Gross Profit Margins (GPMs) can significantly impact your company's financial health and long-term success. The GPM is a crucial metric that reflects the percentage of revenue that remains after the cost of goods sold (COGS) is subtracted. How do you get started with monitoring your GPM?
CSI Accounting & Payroll has helped auto repair shops with their accounting since the 1960s, specializing in it since the day we started! We know the metrics that matter the most for you to keep an eye on - like your GPM - as well as how you can track them.
In this article, we will explore the significance of GPMs for auto repair shops and provide practical tips for boosting profit margins, all based on these questions commonly asked by other auto repair shop owners:
- How do I calculate my current GPM?
- What is the ideal GPM?
- How do I improve my GPM?
Calculating Your Gross Profit Margin
To calculate the Gross Profit Margin for an auto repair shop, you need to know the total revenue generated from parts sales and the total cost of those parts. Once you have this information, you can use the following formula:
Gross Profit Margin = (Revenue - Cost of Goods Sold) / Revenue x 100
Here, "revenue" refers to the total amount of money generated from the sale of parts, and "cost of goods sold" refers to the total cost of acquiring those parts from suppliers.
The Ideal Gross Profit Margin
With the right margin, you can cover your costs, make a reasonable profit, and remain competitive in the marketplace. What is the ideal GPM for auto repair shops? The "long" answer would be that it depends on various factors, such as:
- The location of the shop
- The types of services offered
- The competitive landscape in the local market
The "generally accepted by the industry" answer would be around 50-60% on the sale of parts. However, it's more complicated than that - you can't simply mark up all parts by the same percentage. Remember, it can still be trial and error! The ideal GPM will also depend on a number of factors specific to that business and may require some experimentation to find the optimal level.
Matrix pricing and other best practices can help, which we cover in the next section.
How to Improve Profit Margins
The accountants at CSI Accounting & Payroll have found that when working with auto repair shop clients, we commonly reach a higher overall GPM when we factor in using proper matrix pricing.

Every job is different. However, if your labor sales are significantly higher than your parts sales over time, it usually means that you aren’t marking your parts up enough. Parts and accessories purchased from dealerships are normally priced somewhere lower on the spectrum, while parts and accessories purchased from jobbers are normally priced higher on the spectrum. If your parts sales are significantly higher than your labor sales over time, it usually means that your shop labor rate is too low.
Under this model, you can average a higher combined Gross Profit Margin on labor and parts sales:
What else can you do? To reach higher Gross Profit Margins, repair shop owners should try the following best practices:
- Set diagnostic rates equal to labor rates
- Implement matrix pricing for parts
- Factor drive time before and after repair work into the work order
- Charge for shop supplies and environmental fees
- Negotiate with vendors on parts and supplies
- Track inventory to reduce parts theft
- Evaluate labor rate increases on a periodic basis
- Find opportunities to raise average repair orders
- Focus on customer service to retain quality customers
- Track the productivity of technicians and service writers
- Pay employees using a commission-based system
- Invest in top talent and training
- Develop plans for growth
- Outsource accounting activities
These best practices require owners to stay out from under the hood to monitor the health of their business. If you structure your GPM goals accordingly and track your sales and cost activity, your focus can shift to maximizing volume based on potential per service bay.
