A 65-year-old couple retiring this year will need about $225,000 to cover medical expenses in retirement, according to a health care cost estimate released by Boston-based Fidelity Investments.

This figure is a 4.7% increase over the 2007 estimate of $215,000.

The 2008 figure also assumes that the couple doesn’t have employer-sponsored retiree health care coverage and makes life expectancy assumptions of 17 years for a male and 20 years for a female.
