Manual Premium

Manual premium is the foundational number in commercial insurance pricing: it is the premium you get by taking the insurer's published ("manual") rate for your class of business and multiplying it by your exposure basis. The word manual refers to the rate manuals — historically printed books, now databases — that list a rate for each classification. Because it uses the standard rate and nothing else, the manual premium represents the price for an average risk in your class, before your individual loss history or account-specific characteristics enter the calculation.

For a small-business buyer, the manual premium is important because it is the baseline every discount or surcharge is measured against. If your operation is safer than average, credits pull your final cost below manual; if it is riskier, debits push it above. The relationship between the per-unit price and the total is worth understanding here too — see Rate vs. Premium. In workers' comp, the manual rate itself is often built from a published loss cost that each carrier marks up with its own multiplier, so two insurers can quote different manual premiums for the identical class code.

The key nuance is that manual premium is rarely what you actually pay. It is the input, not the output. From here the insurer applies your experience modifier, schedule credits or debits, and then any surcharges to arrive at the developed premium and ultimately the billed amount. When comparing quotes, ask carriers to show the manual premium separately from the modifications, so you can see whether a lower price comes from a genuinely better base rate or from optimistic credits that could disappear at renewal.
