What Is a Good Profit Margin for an Auto Repair Shop?

The broad average net profit for auto repair shops is 6 to 7%, but that number understates what a well-run operation can achieve. Many owners have a gut sense of where margins stand, yet benchmarks provide a much clearer picture of an auto repair shop’s profit margin.

Industry averages can be misleading because they blend sole proprietors, part-time operations, and underperformers with shops running disciplined operations. A shop with a 7% net margin might assume that is fine since it matches the broad average, but it falls well short of what an actively managed shop should usually aim for.

In the sections below, we walk through the key benchmarks, what most affects them, and where shops often find their next margin gains.

Gross Profit Margin vs. Net Profit Margin

Gross profit margin and net profit margin measure two different things, and tracking both reveals where financial pressure is actually coming from.

Gross Profit Margin

Gross profit margin reflects revenue minus direct costs, mainly parts and technician labor tied to the work performed. It shows how efficiently your shop turns labor and materials into revenue before accounting for overhead.

Net Profit Margin

Net profit margin is what remains after paying every expense, including rent, utilities, insurance, office staff, marketing, loan interest, and taxes. This is the number that shows whether the business is building wealth or simply staying afloat.

A strong gross margin can still produce a weak net margin if overhead is too high, which is why reviewing both numbers together matters.

What the Industry Benchmarks Show

Actively managed shops consistently outperform the broad industry average, often by a wide margin. Two solid datasets give the clearest view of where auto repair shops land on profitability.

Net Profit Margins

The after-tax net profit for auto repair shops is an average of 6-7% of sales. This figure includes the full population, from sole proprietors to part-time operations to underperformers.

The Ratchet+Wrench Industry Survey shows what actively managed shops report. Among respondents who track their margins, 38% report net profits of 15% or higher, and 19% report 20% or more. One of the most useful findings: 25% of shop owners do not track net profit margin at all.

Gross Profit Margins

The same Ratchet+Wrench survey found that 57% of shops report overall gross margins of 50% or higher. The most common bracket is the 50-59% range, where 38% of respondents fall.

RMA financial data supports that range, showing gross margins of 54.5 to 58.3% across multiple fiscal periods.

Quick Reference

If you want a simple way to frame the benchmarks, start here:

• After-tax net profit. 6 to 7% broad average, 10 to 19% for active shops, 20%+ for top performers
• Overall gross profit. 50 to 59% typical, 60%+ for top performers
• Parts gross profit. 50 to 59% typical target, 58% industry benchmark

These ranges are not identical for every market, but they give you a practical starting point for evaluating where your shop stands.

What’s Eating Into Your Margins? The Cost Breakdown

Parts, labor, and rent account for the largest share of revenue in most shops, and when any of these categories drift upward without a matching lift in pricing or efficiency, margins tighten quickly.

Parts, Labor, and Rent

Each of the following categories puts significant pressure on margins:

• Parts and direct costs are the biggest expense at about 44 to 46% of revenue.
• Total labor costs, including technician wages, officer compensation, and benefits, account for about 20 to 22% of revenue.
• Rent lands at about 5.5 to 6% of revenue

When those categories creep upward without corresponding pricing adjustments, the impact on net margin is immediate.

A Rising Cost Pressure

Auto repair and maintenance posted a 6.1% decline in labor productivity in 2024, while unit labor costs rose 10.8%. That marked the steepest productivity decline among the ten largest service industries tracked.

In practical terms, shops that have not adjusted pricing are paying more for labor while getting less output per dollar spent.

The Five Factors That Move the Needle Most

Five operational areas consistently separate higher-margin shops from the rest: technician efficiency, labor-rate pricing, parts-markup discipline, average repair order value, and margin tracking.

1. Technician Efficiency

This is the single biggest lever. The industry targets are 90% productivity (the share of available time spent working) and more billable hours than clock hours. At those benchmarks, each bay should produce more than $25,000 in monthly sales.

2. Labor Rate Pricing

Nearly half of U.S. shops charge $120 to $159 per hour. Regional rates vary meaningfully. California averages around $176 per hour, while Mississippi averages around $110 per hour.

A useful pricing calculation starts with your highest-paid technician’s hourly rate. Apply a 25 to 30% load factor for taxes and insurance, then multiply by 2.5. That gives you the minimum labor rate needed to maintain a 60% labor margin. Pricing below that floor erodes margins no matter how busy the shop is.

3. Parts Markup Discipline

Parts pricing is one of the most common places shops lose profit. Several shops operate below the parts’ gross profit benchmark. One common mistake causes much of the problem. Shops confuse markup with margin. A part bought for $100 and sold with a 25% markup reaches $125, but that produces only a 20% margin. When that miscalculation repeats across parts-heavy jobs, those jobs are consistently underpriced.

4. Average Repair Order Value (ARO)

Every vehicle visit carries fixed overhead, including intake, test drive, and documentation, so completing more work per visit directly improves gross margins.

Digital Vehicle Inspections with photos, video, and written notes are linked to higher ARO values. They also improve approval rates for recommended services by making the needed work visible and easier for customers to understand.

5. Margin Tracking and Visibility

Shops that track their numbers perform significantly better, yet a lot of shop owners do not track net profit margin at all.

A practical way to diagnose margin issues is to review four core levers:

• Car count
• Average repair order
• Labor efficiency
• Parts margin

When margins start slipping, the cause usually shows up in one or more of these areas. Reviewing them monthly lets you catch margin erosion before it compounds into a much bigger problem.

Taking the Next Step With Confidence

Improving the profit margin for an auto repair shop usually happens faster when you focus on one thing at a time. Start by pulling up your shop management system and reviewing your four core levers: car count, ARO, labor efficiency, and parts margin.

From there, identify the single area with the biggest gap between your current performance and the benchmark range you want to reach. Focusing on one lever makes the work more manageable and lets you see progress sooner.
