Two businesses with the same revenue can pay wildly different premiums. Here is what the carrier is actually looking at.
Commercial · Updated September 2026
Most general liability premium starts as a rate applied to an exposure base. The exposure base is usually gross revenue or payroll, depending on the class of business. The rate comes from the classification code that describes what you do. Multiply the two, then adjust for limits, deductibles, experience and credits or debits the underwriter applies.
That is why revenue alone tells you very little. A janitorial company and a roofing contractor with identical revenue sit in different classes with very different rates, because the claims histories of those classes differ enormously.
Your class code is meant to describe your actual operations. Businesses that have changed over time frequently sit in a code that no longer fits — a remodeler classified as a general carpentry operation, a manufacturer that now mostly distributes. Reviewing classification at renewal is the single most common way to find real savings, and it cuts both ways: a code that understates your operations can leave a claim disputed.
Higher limits cost more, but not proportionally: doubling a limit typically costs far less than double, because severe claims are less frequent. That is also why an umbrella policy is usually cheap relative to the protection it adds.
A deductible lowers premium by moving small claims back to you. Whether that is worth it depends on how many small claims your operation actually generates.
Carriers look at several years of loss runs. Frequency often worries an underwriter more than severity, because repeated small claims suggest an operational problem rather than bad luck. A clean record earns credits; a pattern earns debits or a declination.
Underwriters also weigh things that are not on a form: how long you have been in business, subcontractor controls, written safety practices, the quality of your contracts, and whether you collect certificates from subs. Those last two matter more than most owners expect, because an uninsured subcontractor's claim lands on your policy.
Verify your classification every year. Collect certificates from every subcontractor and keep them current. Keep loss runs clean by fixing the cause of repeat claims rather than absorbing them. Shop the market periodically, since appetite for a given class shifts between carriers year to year. And give an underwriter a clear picture of your operation — a well-documented submission consistently prices better than a vague one.
