Gl Rate Calculator

General Liability (GL) Rate Calculator

The total amount of payroll or sales used to determine your risk level.

The rate assigned by the insurer for your specific business class code.

Use 1.00 if no multiplier applies. Values > 1 increase cost, < 1 decrease cost.

For business owners and insurance professionals, determining the cost of commercial insurance starts with the GL Rate. A General Liability (GL) rate is the specific dollar amount an insurance carrier charges for every $1,000 of "exposure." This exposure is typically measured by your business's gross sales, total payroll, or sometimes square footage.

How the GL Rate Formula Works

The math behind a general liability policy is standardized across most carriers. The formula used by our calculator follows the industry standard:

Estimated Premium = (Total Exposure / 1,000) × GL Rate × Experience Multiplier

Key Components Explained

• Exposure: This is the basis of the risk. If you are a retail store, your exposure is likely your gross annual sales. If you are a contractor, your exposure is often the total payroll paid to workers.
• GL Rate: This is a numeric value assigned by the insurance company based on your Class Code. High-risk industries like roofing will have a much higher GL rate (e.g., $45.00) compared to a low-risk office environment (e.g., $2.50).
• Experience Multiplier: Also known as an "Experience Mod" or "Schedule Rating," this factor adjusts the premium based on your claims history or specific safety programs.

Example GL Rate Calculation

Imagine a small landscaping company with the following details:

• Total Payroll (Exposure): $250,000
• Assigned GL Rate: $15.00 per $1,000
• Multiplier: 1.0 (Neutral)

First, we divide the exposure by 1,000:
$250,000 / 1,000 = 250 Units of Exposure.

Next, we multiply the units by the GL rate:
250 Units × $15.00 = $3,750.

The estimated annual premium for this business would be $3,750 before any additional taxes or administrative fees.

Why Do GL Rates Change?

Insurance carriers regularly update their GL rates based on actuarial data. Factors that influence these shifts include:

1. Geography: Doing business in a high-litigation state typically results in a higher GL rate.
2. Industry Trends: If a specific sector (like residential construction) sees an increase in nationwide claims, the base rate for that class code will rise.
3. Coverage Limits: A policy with a $2 million occurrence limit will naturally require a higher rate than a policy with a $1 million limit.

Using a GL rate calculator helps you forecast your fixed costs during the budgeting phase of your fiscal year, ensuring you aren't surprised by insurance audits at the end of the term.
