That's pretty good, considering that by age 30, you should aim to have the equivalent of your annual salary saved. The median earnings for Americans between 25 and 34 years old is $40,352, meaning the 16 percent with $100,000 in savings are well ahead of schedule.

"Just make sure your lifestyle expenses don't exceed 75 percent of your gross income."
