We recommend that you get a policy-specific premium breakdown directly from your agent (or insurer, if you buy direct). Specifically, you might want to ask for a rate worksheet comparison between your last year's premium and your current annual premium. That's a good way to get an apples-to-apples comparison of what your rates are doing.
While you're at it, it's a good idea to make sure that the type and level of coverage is what you want. If you're driving a new car, you'll likely want comprehensive and collision coverage as well as liability (the latter is required by law.) If you're driving a $1,000 car, on the other hand, maybe liability coverage is enough. These are good things to discuss with your agent or company, particularly if you have changes in your life (new car, change in household members, moving, etc.)
