Consumer insurance costs are a function of several factors including the sum of all required products, their discounts, efficiency in service from one source and, most important, the language in insurance agreements stating what will and will not be covered under a claim.
Price comparison analysis should involve securing policy discounts from a combination of products through one carrier. An automobile policy written by itself is more expensive than an automobile policy written along with a homeowners policy and vice versa. Similarly, additional discounts can apply to both the home and automobile if a life policy is written through the same carrier.
So, simply reviewing an auto policy rate compared to another auto rate rather than from an overall program cost will not deliver a true overall cost analysis. Further, cost is also a result of the differences in insurance contract language and not the differences in declaration page coverage limits or pricing.
