CBS News ran the numbers for a 48-year-old in Charlotte, N.C., ineligible for subsidies. According to HealthCare.gov, she would pay $231 a month, but the actual plan on Blue Cross and Blue Shield of North Carolina's website costs $360, more than 50 percent higher. The difference: Blue Cross and Blue Shield requests your birthday before providing more accurate estimates.
The numbers for older Americans are even more striking. A 62-year-old in Charlotte looking for the same basic plan would get a price estimate on the government website of $394. The actual price is $634.
