Estimated Annual Premium
How this calculator works
This calculator estimates insurance premiums using standard commercial underwriting benchmarks for automotive service operations. Garage liability is calculated between $2,500 and $6,000 depending on bay count and revenue scale, while garage keepers coverage is scaled against the estimated aggregate value of customer vehicles left overnight. Workers compensation is computed using industry class code 8380 based on shop payroll and regional risk factors.

How Much Does Auto Repair Shop Insurance Cost?
Insurance costs for automotive repair facilities vary significantly based on business size, location, and risk exposures. On average, a standard independent mechanic shop pays between $4,000 and $12,000 annually for a comprehensive commercial policy package. Premium totals depend heavily on your specific operational profile:
- Small independent shops with 1 to 2 bays typically see baseline premiums starting around $3,500 per year.
- Mid-sized service centers with 4 to 8 bays and multiple technicians generally average between $7,500 and $15,000 annually.
- High-volume collision centers and specialized repair facilities often exceed $20,000 per year due to elevated property values and complex tooling.
- Workers compensation under class code 8380 scales directly with total payroll and state-specific statutory requirements.
Bundling garage liability, garage keepers, and property coverage into a Garageowners policy is usually the most cost-effective approach for shop owners.
What Factors Affect Your Premium?
Commercial insurance underwriters evaluate several core operational metrics when determining final premium quotes for auto repair businesses. Understanding these drivers helps shop owners manage expenses effectively:
- Annual Revenue & Payroll: Higher gross sales and larger payroll figures indicate higher traffic and increased operational exposure.
- Customer Vehicles Overnight: The aggregate value and quantity of client cars left on premises overnight directly dictate garage keepers limits and pricing.
- Geographic Location: State regulations, local litigation climates, and regional weather risks heavily influence underlying base rates.
- Claims History: A clean loss history with zero prior property or liability claims helps secure preferred tier underwriting rates.
Implementing strict safety protocols and security measures can also qualify your shop for policy discounts.
