Many people approaching retirement have a false sense of security that their health insurance will be covered by Medicare. However, a new study by Health View Servicesshows that a healthy couple retiring a decade from now will need 98% of their Social Security benefits to cover their Medicare premiums and other health care costs. Two decades from now that could soar to 127%. The Health View Services’ data shows that for a couple retiring next year, retirement health costs will amount to $366,600 in today’s dollars. This is considerably higher than the periodic Fidelity Benefits Consulting estimate of retiree health care costs, which I cited in The Confident Retirement Journey. Last year, Fidelity estimated the cost to be $220,000, down from $240,000 in 2012. Either way, those are big numbers that need to be factored into your retirement forecasts.
