What Is The Average Cost For A Medicare F Supplement? 
Average costs are almost immaterial . Location , age , gender and tobacco use are the determining factors . Note that the cheapest rates are not always the best choice . Many insurers purchase sell the products through companies which had been inactive . They sell through these companies for a couple of years , then they close the companies to new business . Rates in the closed companies increase while lower rates in the new companies attract younger , perhaps healthier , insureds . So also of importance is how long has the company been selling Medicare Supplements , and what are their renewal rates like . In my area , the monthly rate for a 65 yo male with a Plan F with a major company , everyone knows the name , is almost $ 260/mo It 's new company sells the same plan for $ 140 . mo. . You can expect the rates with this company to rise dramatically in just a few years . Some insurers increase rates by 10-15 % / year , others by 3 or 4 % . If you remain healthy , you can switch insurers . If you do n't , you are stuck .
