When it comes to retirement savings, how do you stack up? According to a report from the Economic Policy Institute (EPI), the mean retirement savings of all working-age families, which the EPI defines as those between 32 and 61 years old, is $95,776.

But that number doesn't tell the whole story. Since so many families have zero savings and since super-savers can pull up the average, the median savings, or those at the 50th percentile, may be a better gauge. The median for all working-age families in the U.S. is just $5,000.

As the charts show, retirement preparedness varies by age. Not surprisingly, younger families have less stashed away. Here's a breakdown of the mean and median retirement savings of U.S. families at every age: Mean retirement savings of families between 32 and 37: $31,644

Median retirement savings of families between 32 and 37: $480 Mean retirement savings of families between 38 and 43: $67,270

Median retirement savings of families between 38 and 43: $4,200
