📋 '''Composite rating''' is a [[Definition:Rating | rating]] methodology in [[Definition:Commercial insurance | commercial insurance]] that replaces individual classification-by-classification [[Definition:Premium | premium]] calculations with a single blended rate applied across an insured's entire exposure base. Rather than pricing each location, class code, or operation separately — as standard [[Definition:Manual rating | manual rating]] would require — composite rating produces one rate per unit of exposure (often per $100 of [[Definition:Payroll | payroll]] in [[Definition:Workers' compensation insurance | workers' compensation]], or per $1,000 of [[Definition:Total insured value (TIV) | insured value]] in [[Definition:Property insurance | property]] programs). The technique is most commonly deployed for large, multi-location, or multi-class risks where the administrative burden of tracking dozens or hundreds of individual class rates would be impractical for both the insured and the [[Definition:Insurance carrier | carrier]].

⚙️ An [[Definition:Underwriter | underwriter]] constructs a composite rate by first computing what the total premium would be under standard classification procedures — applying the appropriate class rate to the corresponding exposure in each category — and then dividing that aggregate premium by the total exposure base to arrive at a single per-unit figure. Experience modifications, [[Definition:Schedule rating | schedule rating]] credits, and [[Definition:Loss-sensitive program | loss-sensitive]] adjustments are typically folded into the calculation before the composite rate is struck. The resulting rate is documented in the [[Definition:Insurance policy | policy]] and used at [[Definition:Audit (premium audit) | audit]] to compute the final premium based on actual exposures reported. In the United States, [[Definition:Rating bureau | rating bureaus]] and state [[Definition:Insurance regulator | regulators]] generally permit composite rating for accounts that meet minimum premium or size thresholds, though specific rules vary by state. In other markets such as the United Kingdom or Australia, where [[Definition:Tariff rating | tariff]] structures are less prescriptive, composite rating arises naturally as part of bespoke pricing on large commercial accounts.

💡 The practical appeal of composite rating lies in its simplicity for policyholders with complex operations. A large retailer with hundreds of stores, warehouses, and distribution centers — each potentially falling under different class codes — benefits from a single auditable rate rather than a matrix of individually tracked categories. This reduces disputes at audit, streamlines [[Definition:Premium allocation | premium allocation]] across business units, and makes it easier for [[Definition:Risk manager | risk managers]] to budget for insurance costs. From the insurer's perspective, composite rating also reduces processing overhead, particularly in [[Definition:Delegated underwriting authority (DUA) | delegated authority]] arrangements where [[Definition:Managing general agent (MGA) | MGAs]] or [[Definition:Program administrator | program administrators]] handle large account portfolios. The trade-off is that a composite rate can mask shifts in an insured's risk profile — if the business quietly expands into a higher-hazard class, the blended rate may not capture the incremental exposure until the next renewal analysis.
