Loss Cost is one of the most important concepts in commercial insurance rating. Nearly every commercial insurance product begins with a foundational cost published by an insurance rating bureau. Insurance carriers then apply their own pricing methodology to arrive at the final premium. Understanding loss costs is essential for product managers, underwriters, actuaries, developers, and insurance organizations modernizing their commercial insurance rating systems. Modern platforms like SelectRate automate loss cost management while allowing carriers to maintain independent pricing strategies.
