As the most common type of workers’ comp for small businesses, guaranteed cost insurance is a predictable, budget-conscious coverage option where the policyholder pays a fixed upfront premium, and the insurer assumes all of the financial risk.
Guaranteed cost insurance is a type of insurance plan where the policyholder pays a fixed upfront premium, and the insurer covers all claims, regardless of their frequency or cost. While guaranteed cost programs come with a higher premium, their budget-friendly predictability offers peace of mind, eliminating the need for large deductibles or unexpected out-of-pocket expenses.
A guaranteed cost plan is typically an option for many types of insurance, including general liability, commercial auto, and homeowner's insurance, but it’s most commonly linked to workers’ compensation coverage.
The main difference between guaranteed cost and loss-sensitive coverage is who carries the financial risk during a policy term. While the insurer assumes 100% of the risk with guaranteed cost plans, loss-sensitive plans put the risk in the policyholder’s hands, in exchange for lower upfront premiums and claim-based deductibles.
