How Much Does Medicare Cost At Age 65? 
Medicare Part A for most people will be free and Medicare Part B will be $ 104.90 per month for 2014 . The premium for Medicare Part B can be higher if you had a higher income over the last 2 years . However , Medicare Part A & B only covers about 80 % of the costs of medical expenses and for this reason many people get a Medicare Supplement Plan -LRB- Medigap Plan -RRB- to cover the difference . These plans can vary in premium based on which plan , your age , zip code and smoking status .
