You should have a pretty accurate budget after about 90 days, Cruze says.
Of course, if you find you're spending more money each month than you make, you'll have to start cutting back until you have a surplus for savings.
The average U.S. college kid graduates from school with about $25,000 in student loan debt, according to the latest figures from the Institute for College Access & Success.
Factor in credit-card debt and a weak job market and lots of Millennials find themselves so far in the red they can't even think about retirement savings."College loans are a big topic of discussion for my generation," Cruze says. "You hear about people in their 30s and 40s who are still paying off their student loans." She recommends paying off all debts -- including college loans -- before even starting to save for retirement. Ideally, you'll pay off all of you debts within a year or two of graduating college, Cruze says. "It takes a lot of sacrifices -- you can't buy clothes and you can't go out to eat -- but you can do it," she says. Save early and often
Regli admits few Millennials can afford to make the maximum allowable annual contributions to retirement accounts -- $17,000 for 401(k)s and $5,000 for IRAs if you're under 50.

If you can't set aside enough money to collect the maximum match, Regli suggests getting as much as you can. "Even if you just get some of the match, it's worth it in the long run." she says.
