10 auto repair shop KPIs every owner should know

Running an auto repair shop goes far beyond fixing vehicles. Many businesses have excellent technical quality and still struggle financially. This happens largely because they don't track their auto repair shop KPIs. These aren't random numbers: they help you understand productivity, profitability and team performance. Here are the 10 most important ones and what each one tells you.

The 10 key auto repair shop KPIs

Average ticket

The average ticket shows how much each customer spends at the shop on average. The calculation is simple:

• total revenue ÷ number of jobs.

A very low average ticket may mean the shop is focusing only on quick jobs and missing opportunities for more complete maintenance.

Rework rate

Few metrics matter as much as the rework rate. When a vehicle comes back, the shop loses productive time, profit and credibility. Tracking the comeback rate and warranty management is essential to measure technical quality and efficiency.

Team productivity

Shows how much of the team's capacity actually turns into billed work. A busy shop doesn't always mean high productivity: there is often idle time or bottlenecks hidden in the routine. See how to calculate productivity.

Average job time

Knowing how long each type of job takes helps with scheduling, pricing and productivity control. This metric also feeds several of the others.

Revenue per mechanic

Shows how much revenue each technician generates. The goal isn't to create competition but to understand individual performance: who needs training, who can move up the career path and how work is being distributed.

Estimate approval rate

Not every estimate gets approved, and this rate shows how well the shop's prices and proposals are accepted. It helps you assess whether prices are in line with the market and whether diagnoses are clear to customers. A very low rate may point to problems in communication or in how the work is presented.

Profitability

One of the best-known metrics, and one of the most misunderstood: high revenue doesn't mean high profit. Many shops work hard and have thin margins because of weak financial control. Profitability shows whether the business is growing in a healthy way.

Customer retention rate

Attracting new customers is essential, but keeping existing ones can be even more profitable. Loyal customers generate more revenue over time and recommend the shop to others.

Vehicles serviced per month

This is one of the most basic metrics, but it is still important. It helps you understand:

• seasonality
• the shop's growth
• operating capacity
• the need to expand.

This number should never be analyzed on its own. Ideally, compare it with profitability and productivity.

Operating costs

Every shop has costs that directly affect profit: energy, rent, tools, wages, taxes, equipment and inventory. When the owner doesn't track these numbers, small losses pile up quietly and undermine financial health.

Start with the basics

You don't need to track all 10 KPIs at once. If you are just starting, see the simple metrics every manager should track and build up gradually. With work orders and finances recorded in a repair shop management system, gathering this data becomes much easier.
