Each insurance provider determines how much its Medicare supplement plans will cost. Pricing is usually done in one of three ways:

• Attained-Age: The majority of companies use this pricing style in South Carolina. In this pricing style, your rate is determined by your present age, which means that as you get older, your premiums will rise.
• Issue-Age: This is the second most popular pricing style used by companies in the state. Your policy's pricing is determined by your age when you initially purchase it — it will not vary as you get older, but it may increase due to inflation.
• Community-Rated: Every policyholder in a specific plan type pays the same monthly premium. For Plans D and M, insurers do not employ this pricing method.
